Dead and dying cordless drill batteries

And Then There Were None

All of my cordless drills were using Ni-Cd cordless drill batteries and like any rechargeable battery, you reach a point in time when the battery begins to lose the ability to hold a full charge, then to hold a charge at all. One by one, my rechargeable batteries succumbed to age, as they reached their maximum number of charge cycles and stopped working. The Makita died first, then the DeWalts and the Black and Decker. The Skill was next, then the Ryobi. The Fein is nearing its greater reward as well. Where I once had drills to spare, I now have a collection of tools with dead and dying batteries.

Thankfully the Fein drills are still working, but they do not last as long as they once did. The clock is ticking… No problem, I thought I would just get some new batteries and I would be back in business. I had been putting off buying new batteries because I always had several other drills that were working. When I began to have more dead batteries than working ones, I had had enough and I drove to the local mega-hardware box store to get a handful of new batteries.

A Rude Awakening

Whoa Partner! The cost to replace two batteries with most of the models was 50% or more of the original cost, with each battery costing give or take at the time (They have come down a bit since that time). Humm… I decided to cut bait instead of fish and I left the store with nothing. On the drive home I thought that with the high cost of replacement batteries, I might as well buy a totally new one, which comes with two new batteries and a new charger. Sounds good, but then what do you do with the old power heads? It’s easy enough to take the dead batteries to the recycling centre, but what do you do with several power heads that still work, but just need a good battery?


With no easy solution at hand, I decided to check into getting the batteries rebuilt at a local battery rebuilding service. Rebuilt batteries were about half the cost of factory built new batteries, so I thought that might be the way to go. At least it would be cheaper and I could get higher Amp-hour batteries installed during the rebuild. More power! Using rebuilt batteries also allows the continued use of my existing power heads, which are still in good shape. As I was getting ready to drive back over to the power tool battery shop to drop off 10 – 12 battery packs to get rebuilt, I quickly added up the cost.

Whoa Partner! At per rebuilt battery, I would be pouring a significant amount of money back into several old tools. Some of which (like the 9.6volt and the 14.4volt), lacked enough power and run time for my current needs. Being born in the year of the rat made me want to stretch more life out of the older ones, but the numbers were not adding up. I kept looking around the Internet and found a few companies that sold new “no-name” battery replacements for a little less than the rebuilt ones I was quoted.

Decisions, Decisions

However, I had never dealt with any of these companies before and most of the websites offered little, or no technical specs on their batteries. Without knowing the Amp-hour rating of the batteries, it makes it hard to compare different brands, so I kept looking. The new Lithium-ion cordless models were beginning to lure me into the abyssal vortex. Lithium-ion batteries are smaller and lighter than the same voltage Ni-Cd battery, which is a big benefit since my 18volt gets tiresome after using it all day.

I also thought about getting a 24volt, but the 24volt models seemed to be made for folks with forearms like Popeye the sailor man. Luckily, I never succumbed to the lure of 24volt drills. They were just too heavy to use all day, or for the occasional odd job around the studio. Then came the 28volt models, then the 36volt mega-extreme… I resisted once again. The Lithium-ion versions of the higher voltage tools were quite a bit less in weight, but still seemed like overkill for what I needed.

While it’s easy enough to just buy a new drill or two, the dilemma of what to do with my old power heads remained. It seemed like a waste to just throw them away! I guess old cordless tools are a lot like other tools and equipment, when they quit working you just get a new one and pitch them into the rubbish bin.

Another Option

One last option that I considered was to get a few Lithium-ion batteries for my existing 18volt DeWalts. The DeWalt line of 18volt tools can use the newer lithium-ion batteries, as well as the regular Ni-Cd’s, but you have to get a new charger to use the Lithium-ion batteries. So if you’re thinking about doing this as well, add up the costs before you lay out the plastic.

Two DeWalt Lithium-ion 18volt batteries and a charger are none too cheap. (One 18volt DeWalt Lithium-ion battery and a charger is around £108.83 ($179.00), two batteries and a charger is about £187.26 ($308.00), which is the same cost as a new 18volt DeWalt ½” NP-Lithium-ion cordless model, charger and two batteries – £187.87 ($309.00) at a large online merchant.

Note: There is no difference in power or run time between Ni-Cd and Lithium-ion batteries of the same voltage and Amp-hour rating. None, zip, nada. The main benefits of moving to Lithium-ion batteries over Ni-Cd’s is less weight, a more compact size and virtually no self-discharge of the battery when not in use. Lithium-ion formulas vary however, some are better or worse than traditional Ni-Cd’s, or NiMH batteries.

Decision Made

Well, after much deliberation I have decided to get a new 18volt Nano-Phosphate Lithium-ion based cordless drill (DeWalts NPLI battery is good for 2000 recharges, versus 800 recharges for their current Ni-Cd battery), instead of replacing/rebuilding my old dead batteries – with one exception! The Fein drills are just too well made and smooth running to discard, so I’ll be keeping those and rebuilding their batteries in the near future. As for my old DeWalt drills, those will get pitched/recycled and the Bosch power tool batteries will go to my local recycling centre.

The logic for keeping the old cordless tools and rebuilding them just never worked out. Not when I can get a brand new model with Lithium-ion technology that weighs less, for less money than rebuilding all of the batteries for the old drills. Now all I have to do is decide which new drill I want. If any of you have a Lithium-ion drill and you like it, let me know. If you don’t like your new Lithium-ion drill, let me know that as well. I still can’t get used to the idea that a drill costing a few hundred dollars is disposable!

Safety Note: Always follow all manufacturers safety instructions before working with your lathe, or any of the tools or products you may use. If you are unsure about any operation, obtain competent professional instruction before proceeding. Use and wear all necessary safety devices during turning and observe safe woodturning practices to prevent accident or injury.

Share Important Lawn Care Tools Homeowners Should Have

Lawn tools usually fall into 3 categories – basic tools, specialty tools and tools to rent.

Basic Lawn Care Tools

Garden Rake – This is a steel-headed rake that is very useful for preparing small areas for

the planting of plugs, sprigs and seed.

Wheelbarrow – This will haul everything from lawn tools to lawn waste to fertilizer.

Shovel – This is used primarily for large quantities of fine-textured material like soil,

sand or non-fibrous mulches. Consider selecting by weight of Craftsman tool batteries. It will be a lot easier for you to

dig if you make use of a lighter shovel.

Spreader – Precision is the main difference between a rotary and drop spreaders. A drop

spreader will distribute fertilizer, seed, and other amendments. Settings will let you

control the amount distributed. A rotary spreader, on the other hand, will fling seed or

amendments over a wide area. However, this is should not be used for irregularly, small

shaped lawns.


Edger – This is a half-moon-shaped cutting head that is mounted to a hardwood handle in order

to keep the lawn edges neat. It can be used to cleanly separate a lawn from paved surface. It

offers a more finished appearance as it trims away excess sold if you lay the sod along

irregular lawn edges.

Specialty Tools

Blowers – This is powered either by gas or electric. Also, they can be wheeled, hand-held, or

backpack styles. Though you can just rake leaves on the lawn, you will surely appreciate the

help of a blower to move leaves out from under the shrubs. Some recommend investing in

electric blowers since they are quieter and won’t have emissions.

Power Edger – This is a Black & Decker drill battery with a short blade that will trim grass vertically to create

edges or horizontally at lawn edges.

Saw – An electric saw is a great tool for cutting tree limbs and trunks. This can handle most

chores. This is quiet, low maintenance, always read to go, and won’t emit exhaust fumes.

Tools To Rent

Earthmover – This will include bulldozers, power shovels, excavators, backhoes and many more.


Power Aerator – This is available in different styles. It loosens compacted soil by drilling

many small holes in it.

Vertical Mower – This is like a lawn mower that can be used for dethatching and scarifying

the soil in preparation for efficient seeds. This has different vertically mounted blades set

in order penetrate the soil slightly.

Lawn Roller – You can use this cordless drill batteries to prepare the soil for planting. Though this is

inexpensive, this will take up storage space.

Make Sure Your Next Cordless Drill Driver is Equipped With Lithium Ion Batteries

If you’re going to purchase a cordless tool, then you should really think about getting one with Lithium ion batteries. They cost more, and it’s easy to think you could just buy a cheaper model and get a spare battery, but it’s not the same. Craftsman power tool battery are a true hassle free solution.

Lithium ion batteries, or Li-ion as there often called, have got a lot going for them when you use them in cordless tools. They have twice the power density than other rechargeable types, so you get a smaller lighter tool. It’s not just the power density that makes them smaller, each Li-ion cell has three times the voltage of an ordinary cell so it only takes a third of the cells to get same output voltage.

Li-ion cells have a good peak output current and low source resistance. When you overload the tool, the voltage stays up, and they just keep pumping current into the motor. Power tools have thermal overload trips in the motors, and that’s a good thing with Li-ion batteries, if they didn’t they’d just burn the motor out!

And charging is the best thing about Li-ion batteries, there’s absolutely no memory effect. And they charge quickly. Battery manufacturers always like to say they’ve reduced the memory effect, or even ‘virtually eliminated’ it. But it’s never true, you might get away with charging the Black & Decker cordless drill battery from half full every now and again, but if you keep topping them up then the capacity always goes down. With Li-ion they don’t need to reduce the memory effect, there isn’t one.

I use a Makita 18 volt drill with Li-ion batteries. It’s a bit smaller and and lighter than ordinary 18V cordless drills, but it’s as powerful as the best NiMh battery drill, and makes NiCad ones seem like toys. But it does twice the work of other drills between charges.

Li-ion batteries can be topped up whenever you want, and you can start using them again even if they haven’t had time to fully charge. Use the tool all morning, put the battery to charge over lunch, use it again all afternoon. You never have to stop work to go and change the battery.

Li-ion batteries have a low self discharge rate as well, that means the battery stays charged longer when you’re not using it.I also have a Milwaukee Sawzall with Li-ion batteries. For some jobs I’ll be using it all day, and put it to charge at night. But a lot of time I’m just using it for the odd cut here and there, and I just don’t bother charging it. It never discharges itself, I don’t think that saw battery has ever been flat, but I only ever charge it for the big jobs.

Next time you get half an hour into a job, and your old battery for Cordless Drill Driver runs out of juice again, think about getting your next cordless drill with Lithium ion batteries!

Battery Reconditioning Suggestions

Battery reconditioning is among the most upcoming eco friendly ways to reduce your footprint right now. Saving cash via electric battery reconditioning is attractive due to the very high cost of panasonic cordless drill batteries and their limited life. With all the portable battery powered devices and electrically powered vehicles on the market today it is more important than ever to learn to reuse batteries.

You merely require a reconditioning program and you can be moving toward reconditioning automotive, motorcycle, wheelchair, and marine batteries; along with other lead acid electric batteries. Reconditioning requires a little bit understanding and a few cheap tools. It can be achieved by almost anyone, but we should first know the way a battery works. Battery reconditioning generally functions much better on non-maintenance free Ryobi tool batteries, but could work with both.

I have looked at many different e books and videos to learn the best way to recondition my batteries, and i have found that most of the techniques do not work well. On the bright side, i have found a few that do. One of many objectives of reconditioning them is to eliminate the sulphation developed on the battery. After that one needs to make sure that before recharging the battery, that the battery is completely drained before it is put on the charger.

As far as tools needed to properly recondition a battery, everything need is relatively inexpensive. That is not to say that one could spend a lot of money on top of the line tools and various specialty tools. For most basic reconditioning techniques and the majority of batteries out there, though, I have found it to be very cheap when considering the alternative to buying a new car battery for instance. So I invite you to look for alternative ways to re using your worn out power tool batteries instead of throwing batteries and money away to get new ones.

How to Repair Cordless Power Tools

But let’s say you have a cordless tool, and its battery is failing. Can you fix the battery? Of course you can. You are Hackaday readers, you’ll all be aware that inside almost all cordless tool batteries you’ll find a set of standard off-the-shelf cells wired together, C or D cells in the case of NiCd or NiMh Bosch power tool batteries, and maybe 18650 cells for LiIon. If you can defeat the efforts of your tool manufacturer to discourage battery pack dismantling, you can have them out on your bench, and replace them.

Of course, there is a snag to replacing cells in a pack. This isn’t like the spring-loaded battery compartment in your radio, each cell will have spot-welded metal strip conductors linking it to its neighbour, and you’ll have to come up with a way of replicating that. If you’re lucky you’ll find solderable batteries, otherwise you’ll have to consider a battery welder. But if you can overcome that hurdle, you should at least be able to replace your cells without breaking the bank.

You will be unlikely to find a tool with a NiCd battery for sale new these days, but there are still huge numbers of older ones with dead packs to be found often at next-to-no outlay. It’s not the safest of exploits, but it is possible to rejuvenate dead NiCd cells with the application of short bursts of high current. The theory goes that metal crystals grow in the cell and short it out, and the high current blows these metal crystals and brings the cell back to life. There are tales of this being performed with hefty bench power supplies, car batteries, and arc welders, though you may wish to research carefully before you give it a try.

Finally, who needs cells? If you have a suitably powerful low voltage supply, why not run your tool directly from it and forget about the battery pack? Of course, you lose the ability to run it as a cordless tool, but if it came to you at very little cost than that should present very little hardship. Try a modified PC power supply if it’s a 12 V tool, or a lead-acid pack if it isn’t.

So we’ve got past my rant about the iniquity of the built-in obsolescence of cordless power tools, and identified several ways that we as resourceful Hackaday readers can benefit from the cast-offs of others whose batteries have reached the end of their lives. It doesn’t change my personal view that I’d always still buy a tool with a cord by choice, but at least there are ways forward for those stuck with failing cordless tool battery. Do you share my feelings on this topic?

My battery pack had a thermister that aged, and was also susceptible to corrosion. It was unidentifiable by the time I saw it. If I knew what to replace it with, and had a strong confidence in not burning down my house or drill, I would rebuild it myself.

I’m not much into power tools, but I see the category is a huge opportunity for vendor lock-in and reduced tool quality (it’s battery-powered, so less sturdy, etc), and clearly some vendors have taken advantage.

Is the usefulness of battery tools that there is no cord, or that you’re independent of the grid?

It seems to me a good option would be a separate battery pack with an inverter, from which you could operate several corded tools. Aside from the cord issue, you’d have just one battery to charge rather than many, it would be separate from the tool, so would not affect handling, and could be larger and therefore higher capacity/power Dewalt cordless drill battery. it could be non-proprietary relative to the tools, and you’d be able to use more ‘standard’ corded tools.

Picking the Right Power Tools for Your Own Needs

A lot of time when people need new Panasonic power tool battery they will either go to the store and look around, do a little research online, or maybe even ask friends or family for recommendations. This is a good way to get some opinions.

If you are going to be going to the store to check out what is available, it is best to be prepared ahead of time. You should familiarize yourself with common trends for each type of tool you need and then figure out what features are the best fit for your situation. You can save yourself a lot of money by looking at what you need rather than what is the “best”.

What are some example of what I’m talking about? Let’s take a look at the example of cordless drills and drivers. You might be tempted to buy something that has Lithium Ion batteries and hammering action, and possible 18 volts of Milwaukee cordless drill battery. That would be nice, but it will also be expensive. The description of what I just threw out there is for contractor grade tools.

What are you going to be using the drill for? Let’s say that you are planning on building some light furniture and maybe will use the drill on weekends mostly. You probably don’t need a super powerful drill with the most expensive battery technology. You could probably get by with a 12 volt drill, no need for hammering action, and you could probably do fine with a NiCad battery as opposed to Lithium Ion. Sure, a Lithium Ion battery would be really nice, and would charge faster, but if you aren’t planning on using the drill for continuous hours at a time you could save a few bucks in this department.

See what I’m doing here? I’m trying to find the specific features that I probably do need, and then going out and finding a tool to match those needs. This will help me to maximize my dollars and get what I need all at the same time, rather than blow all my money on a battery for power tools that may be a bit overblown for my needs.

Ways of Choosing a Laptop Battery

Laptops are eating up PCs’ market shares for its portability. But if you want to take advantage of the laptop’s portability, you need to make sure the battery of your laptop is durable enough. If not, you need get a new replacement lap top battery. So how to choose a Fujitsu laptop battery?

The first thing you should consider when you choose a laptop battery is the reputability of the batteries. There’re many laptop manufacturers on the market. If your budget is not so tight, then the best choice would be a battery made by the manufacturer of your laptop. But those batteries would be much more expensive than the average price in the market. Dell, for example, has been known to charge four times more than ones you can get elsewhere. Therefore, if you don’t want to pay the high premium price, you can get one from a different manufacturer.

Actually many famous laptop battery manufacturers don’t actually manufacturer, instead they are the brander of the product. For instance, if you open up a genuine Samsung laptop batteries, you may find that the power cells inside are actually made by Toshiba, Panasonic, or a similar big name company. Many third party brands use the exact same power cells as original manufacturers, and they cost much less than the original ones.

Another thing you should consider is the type of the battery. Normally there’re 4 main types of laptop batteries: nickel cadmium (NiCad) battery, nickel metal hydride (NiMH) battery, Lithium ion (Li-Ion) battery and Li-Poly battery. NiCad battery is very old and primitive; it’s rare in the market now. Ni-MH is newer and more advanced, but is not as good as its Li-Ion and Li-Poly counterparts. Li-Ion and Li-Poly are the most advanced and common types of batteries on the market. You should be clear what type you laptop battery is, because most of the laptops are designed with one type of batteries and cannot be used with other types. For example, if your original HP laptop computer battery is Li-ion, then you should get a Li-ion replacement battery.

Another important thing you should really pay attention to is the power rating of the battery. Batteries with the same physical size may vary greatly in power ratings. Normally batteries are rated by Volts and Amperes, though most companies show battery ratings with Volts and Milliamperes (or mAh). One thousand Milliamperes equals 1 Ampere. However, some batteries have both different Volts and Milliamperes, then it’s hard to compare which one has stronger power. Actually there’s another way to rate the power: by Watt-Hours. Watt-Hours is just multiplying the Volts and the Amperes together. So you can easily find out which battery has more power.

There’s one more thing you should be noted: be careful with the used or refurbished batteries. Because refurbished batteries do not hold as much power when compared to new LG notebook batteries. Also, they can kick the bucket on you randomly since you really do not know how old the battery is.

Power Tool Battery and Electric Drill

An electric drill is doubt the most commonly owned by homeowner working on their home improvement tasks and is most likely the first Milwaukee power tool battery purchased by the newbie.

There are two major kinds of electric drill the corded and cordless which comes with their own pros and cons.


Corded electric drills have a dangling wire and plug which requires an electrical supply. As a result it can restrict your working range from an electric socket but you can extend your range by using an appropriate extension. When you in the range of a socket, this power tool is simply plug it in and begin drilling thing.

They tend to have more power and have higher speeds as compare to cordless version. With the exception of the smallest drills, they are usually overly bulky to be utilized by simple screwdrivers.

The power rating for corded electric drills is usually used is wattage in the UK and horsepower in the USA. The drill with the higher wattage equals to a more powerful drill. Most household models are in the scale of 500 to 1000 W.

The strength of a single drill is usually revealed by its wattage, a higher wattage Dyson Vacuum battery should is equipped with more sturdy bearings and gearbox. A low wattage drill that is stretched will be operating at maximum power every now and then would be pushing its bearings closer to their limits. While a higher wattage tool will use lesser effort to performance the similar job, with a resulting in reduction of wear and tear. In plain terms, the more you are going to work the drill, the higher the input wattage should be.


In the recent years, cordless power tool like the electric drills have achieved immense progress and can offer same performance to the majority of corded drills.

The distinct advantage over the corded version is that they are not restricted by the wire, but it relies on the limited power of the battery pack. Fortunately, majority of models come with replaceable battery packs and include a spare, the electric drill will come back life with a fully charged battery pack.

Voltage is usually used for rating these type of power tool, the higher the voltage, the more power it has. Most household models come in the range of 9.6 to 16 volts battery pack, there also some that come in 32 volts battery packs which are targeted for the professional usage.

It is an obvious advantage to have a minimal of a single replaceable battery pack. Various kinds of cordless drill batteries are utilized on various models; the two general types are Nickel Metal Hydride (Ni-Mh), Nickel Cadmium (Ni-Cd).

To sum it up, we have gone through the two different version of this power tool. Generally corded drills offer higher power and higher maximum drilling speeds than cordless ones. However, cordless drills offer higher flexibility without the hassle of messy wires.

Evolution Of Rechargeable NiMH Batteries

The widespread use of Rechargeable NiMH Batteries owes its roots to the early years of development of rechargeable battery technology.

The first rechargeable bosch drill battery was the lead-acid battery invented in 1859 by a French physicist by name Gaston Planté. Widespread electrification in Europe led to the use of storage batteries for portable lighting systems, telegraphy, and back-up power. The most remarkable use of these batteries was for electric cars and probably here the rechargeable batteries found the largest market. But eventually, internal combustion engines prevailed for a host of advantages and so petrol-driven cars replaced electric cars.

Nickel cadmium cells made its appearance in 1900 and found acceptance where more power was needed. But, a drawback of both lead-acid and nickel-cadmium batteries was they produced a lot of gas when overcharged. A German engineer by name Neumann plugged this issue by making possible a sealed version. By 1960s sealed batteries were widely available. For most part of the last century lead-acid and Nickel-Cadmium batteries dominated the market. Even today small lead-acid battery packs provide the initial bursts of power in almost all cars, whereas nickel-cadmium batteries provide emergency backup power for aircraft and trains.

Technological evolution is an inevitable part of our life. It is not surprising therefore that better batteries sooner or later had to make their appearance. Nickel-metal hydride battery came into the market in 1989. These batteries had an advantage of storing twice as much energy as that of lead-acid batteries for identical weights.

Rechargeable NiMH tool batteries have become all-encompassing in today’s technological climate, powering everything from laptops and cellular phones to hybrid electric vehicles.

The development of NiMH battery traces its origin to the nickel-hydrogen batteries used for aerospace applications. Nickel-hydrogen batteries were specifically suited to aerospace applications because of their exceptional life cycle and acceptable specific energy. But, the drawbacks were poor volumetric efficiency and the need for tanks of hydrogen gas and platinum catalysts. NiMH batteries overcame this problem by configuring a battery using metal hydride storage materials as one of the electrodes. The sustained work done in multi-component metal hydride alloys has been singularly responsible for the current generation of high performance and durable Rechargeable NiMH Batteries. These are in use today in nearly every application you can think of.

The NiMH battery is actually an alkaline storage battery because it uses potassium hydroxide as the electrolyte. Rechargeable alkaline batteries found wide application for the following key reasons.

* High electrolyte conductivity.
* The battery system can be sealed to plug leakage problems.
* Operable over wide temperature ranges.
* Longer life and durability compensating for higher initial costs.
* Higher energy density and lower cost per watt-hour.

One significant technological development in Rechargeable NiMH Batteries is in the field of battery packs used in hybrid electric vehicles. The battery packs are now considerably reduced in size, weight, and cost, without compromising in power, reliability, and life expectancy. This has enabled these batteries to be selected for mass production of hybrid electric vehicles (HEVs) of makes such as Honda Insight and Toyota Prius. Adapting the NiMH battery technology to cars was no mean feat because the way batteries work for hybrid cars is very different from the way they work in portable devices. Rechargeable NiMH Batteries in laptops and cell phones are designed to discharge over a period of several days. Dyson batteries for hybrid cars, on the other hand, need to sustain for several years and must endure umpteen cycles of absorbing power, regenerative braking, and supplying short bursts of power.

Hopefully, in the near future rechargeable NiMH Batteries or its successors will have wider and more extensive applications and will make us use gas engines less and less.

How to Choose the Right Cordless Drill

A cordless drill is essential for anyone who enjoys woodworking, masonry, home improvement, or any other hands-on construction activities. This wonderful tool allows you convenience and mobility that is difficult to attain in a traditional corded model because there is no need for finding a close outlet or maneuvering around a heavy extension cord. There are thousands of models of cordless drills on the market today in prices ranging from well below $100 to more than $1,000. How can you choose the cordless drill that is best suited for you? Selecting the perfect Ryobi cordless drill battery can be easily accomplished by looking at a few important factors.

First you should evaluate your needs. Think of the conditions and durations for which you intend to use it. If you will only be using it for small, everyday activities, you hardly need a $1,200 professional drill. Alternatively, if you plan to do massive projects or heavy-duty drilling, you may prefer a higher-end drill that has additional features such as a ½” chuck as opposed to the traditional 3/8″ chuck. Also decide if you need a keyed or keyless chuck. A keyless chuck makes it faster and easier to change bits but a keyed chuck can be more secure for heavy jobs.

Another thing to consider when choosing a cordless drill is the battery type and size. The newer Nickel-Metal-Hydride batteries are smaller and last longer than the Nickel-Cadmium batteries. If you only intend to use your drill occasionally for small jobs, the minimum recommended power is 9.6v. You may want to stay with 12v and above, however, if you will be doing larger jobs. Often, drills in the 14.4v to 18v range can be found for under $100 and provide a better value for the dollar than smaller drills. It is important to remember that more voltage means a higher drill weight, something to consider if you will be holding it for very long periods of time.

Once you have a basic idea of the type of Black & Decker power tool battery you are looking for, make a trip to your local home improvement store and try out several models for performance and function. Don’t overlook things like padded or rubber grips. These seemingly unimportant features can make a big difference after holding the drill all day. While testing models, check for clutch change settings. The perfect setting for you depends on your strength and hand size. More available clutch setting choices give you more control over the speed of the drill.

After you have narrowed your choices down a bit, check the cost of replacement batteries. If you are buying a cordless drill to last, you don’t want to find out later that the replacement batteries cost as much as a new drill. Also find out the life expectancy of the included batteries. You may find a slightly more expensive drill is a better value than a cheaper model once battery life and cost is added into the equation.

By taking the time to do your research and test several options, you can be assured that you will find a cordless drill that you will be happy with long-term. So do some testing, compare some options and low prices power tool batteries, and pick your perfect drill. You will be checking items off of your to-do list in no time.
