How to Disinfect a Vacuum Cleaner

Just because a vacuum helps create a clean home doesn’t mean it doesn’t need cleaning, too. Your vacuum removes dirt, debris and other stain-causing substances from floors and furniture on a regular basis. Vacuumed debris may contain bacteria or mold, so it’s important to clean and disinfect the vacuum cleaner on a regular basis to ensure bacteria and mold spores don’t spread to other areas of your home. You can kill germs, bacteria and mold and maintain a Dyson clean battery, sanitary vacuum with simple supplies and procedures.

Toss out the old vacuum bag. Place the bag in a plastic trash bag and seal it to prevent mold or bacteria from transferring to other surfaces.

Spray the inside of the vacuum with disinfectant spray to kill germs. Wait two to three minutes before putting a new vacuum bag inside and closing the vacuum. If there are any fabric-covered areas on the vacuum, spray them with the disinfectant spray, too.

Pour 1 qt. undiluted white vinegar into a bucket. Wet a clean cloth with the vinegar and wring out the excess moisture.

Clean the exterior of the Dyson DC45 vacuum battery by wiping it off completely with the vinegar. Rinse the cloth as dirt and stains are removed. Apply more vinegar and continue to clean until you’ve cleaned the entire vacuum. Dry the vacuum with a clean cloth.

Dampen a clean cloth with rubbing alcohol. Disinfect the vacuum cleaner by wiping it off with the rubbing alcohol. Allow the vacuum to air-dry so the alcohol can kill any bacteria or germs left behind.

Disinfect the vacuum handle and other areas commonly touched each week. Give the entire vacuum a cleaning once each month. Increase cleaning and disinfecting, as needed, when there’s been exposure to illness or mold.

Always unplug the Dyson SV05 vacuum battery and any other electrical appliance before cleaning.

Replacement Power Tool Batteries from Third Party

The time has come to replace your lithium-ion battery or perhaps you just realize that it’s handy to have a spare or two. So you load up in the pickup and head to the local hardware store where you bought your beloved cordless tool. As the helpful salesperson leads you locate the appropriate replacement Paslode tool batteries, you start to notice the price tag. $50, $75, even $100 or more! Panic begins to set in and you wonder if you can find a better deal online.

Once you get home, you fire up the old Commodore 64 and wait through the modem’s pig squealing to connect to the internet. A Google search of “Replacement Tool Batteries” brings up over 16 million sites to choose from. Of course, you’re looking for the best price. A battery is a battery, right? Eh, not so much. There are hundreds of variables in creating the lithium-ion battery that came with your tool in the first place. Just take a look at what we discussed with Paul Fry of Milwaukee Tool. Let’s look at the problems with aftermarket and knockoff replacement tool batteries. Then you can decide for yourself if going cheaper is worth it.

There are a host of potential issues that come from using aftermarket replacement tool batteries. Here are the most common considerations you should think about before slapping a third party battery that was half the cost in your cordless tool. When it comes to the design and makeup of the batteries, manufacturers protect their secrets. Some third party manufacturers may try to reverse engineer them while others just want to make the tool do something when you press the trigger. Either way, they won’t be recreating the exact original design, and that will cause problems.

The design that the manufacturer uses for their DYSON Vacuum Cleaner Battery is very specific. It helps to dissipate heat, which is the #1 lithium-ion battery performance killer. It also is responsible for how the battery directs any moisture away from the cells and vibration protection.

The cells differ greatly and literally hundreds are available that produce power in a battery pack. There are different lithium salts used as the electrolyte. There are many options for the type and amount of material used as the cation and anion. The cells aren’t as simple as a grouping of AA batteries working together. Adjusting any variable in a replacement battery cell can affect heat production, power output, run time, and more.

If you read no other part of this article, read this regarding replacement tool batteries!!! Today’s cordless tools rely on communication between the battery, tool, and charger. This prevents fatal damage to the tool or battery during charge or discharge. Aftermarket and knockoff batteries do not communicate with the tool the way it was designed and bypass all of the features designed to protect the tool and battery. After all, that communication is proprietary and carefully guarded.

First of all, most manufacturers warranty their batteries for at least a year. Some go 2 or 3 years and Ridgid offers free replacement tool batteries for life. Fill out the registration online and save your receipts. This simple step may alleviate the problem altogether. If you choose to go with a third party battery, there is likely no warranty on it and your cordless tool warranty is voided the moment you lock it in to the tool. If your tool fails due to the aftermarket battery, they will be able to tell and will not honor the warranty.

Did you know that lithium is one of the highly reactive elements on the Periodic Table? Yep, the same chemical makeup that makes it a great element for rechargeable batteries also makes it a great candidate to fail in a very spectacular way. In fact, if you are willing to sacrifice your battery, you can shoot many models out there and witness a fiery death. On second though, don’t actually try that at home. Leave that to the pros. The point is, if you don’t take care in both the creation and protection of the battery, it can lead to a very serious and literal meltdown. While most batteries use a lithium-iron-phosphorous ion that is relatively stable, poor construction or poor chemistry makes them unsafe in a hurry.

As I eluded to when talking about the battery cells, the change of any variable within the battery will affect performance. Run times will be reduced, power and torque will be lower than the manufacturer’s specifications, and heat will be a major problem. This is due to the use of cheaper materials and the way that they are put together in the housing. In addition to the performance of the tool itself, the balance and ergonomics of the tool will be thrown off by the adjusted size and weight.

Let’s get this out in the open now. Most Hitachi cordless drill batteries are already manufactured in China as it is. Original manufacturer batteries are produced by reputable companies that match the specifications in a way that produce reliable results. Many knockoff replacement tool batteries are not being produced with the same tight specs. At best, they are attempts at reverse engineering that fall short. At worst, they barely resemble the original battery and fit poorly.

Here’s some food for thought. Do you really want to buy a battery from a company made up of people that stole the design from the manufacturer to reproduce it for their own gain? Because that’s what they’re doing, even the really poor quality ones. I came across a site that sold DeWalt replacement tool batteries, X Box game systems, and dishware. Do you think that company is committed to producing quality tools? Heated jackets are now very popular. Do you really want to put one of these knockoffs in a garment that you are wearing? Something tells me that won’t end well.

Look, I know that you want to save money. I do, too. There are companies in China making knockoff Apple computers, SpyderCo knives, power tools, batteries, and any name brand item they think will sell. They’re thieves. They’re happy to take your money and have absolutely no qualms about sending you a piece of junk in exchange. Even the third party manufacturers, as much as they may try to produce quality, won’t be able to match what the original manufacturer’s battery is designed to do. Do yourself a favor and only go with original manufacturer replacement tool batteries.

How to Repair a Jacobs Drill Chuck

The Jacobs chuck is the mechanical device on the tip of the drill that fastens all drill bits and extensions in place. Jacobs drill chucks are commonly used in high-powered electric drills. When your Jacobs chuck breaks, repairing the chuck means replacing it with a new chuck. This requires that you partially dismantle the drill, which can void your drill’s warranty if you cause damage to the drill while replacing the Milwaukee power tool battery.

Unplug your drill’s power cord or remove the battery pack if your drill is cordless. Disable the drill’s trigger by pressing the locking button above or near the trigger. Place the drill on a sturdy work surface.

Grasp the chuck and rotate it counterclockwise until the jaws are fully expanded.

Determine how the chuck is fastened to the drill’s spindle. Most Jacobs chucks are fastened with a single screw. This will be either a Phillips screw on the bottom side of the chuck or an Allen screw inside the chuck. Since most Jacobs chucks use a left-handed screw, turn the screw clockwise until the screw is removed from its threaded hole.

Insert the hex wrench that came with your Ryobi cordless drill battery into the Jacobs chuck. Place the drill so the chuck is hanging off the side of your work table. Strike the wrench so the chuck rotates counterclockwise. This will knock the chuck loose from the drill’s spindle. Remove the chuck from the drill.

Place the new Jacobs chuck onto your drill’s spindle so the threads on the spindle align with the threads inside the chuck. Rotate the chuck clockwise until it is firmly fastened to the drill’s spindle. Reattach the chuck’s retaining screw and tighten by turning it counterclockwise.

Power Tool Brands Don’t Make Their Own Batteries

Power tool brands might make their own battery packs, but they don’t make their own batteries. Panasonic might be the only exception.

I spent the past two hours or so disassembling 18V 3.0Ah and 4.0Ah Ryobi cordless drill battery packs and examining datasheets, at least those I could find online.

All major power tool brands build their 18V (or 18V-class) battery packs with (5) or (10) 18650-size rechargeable Li-ion cells.

Bosch, Milwaukee, and Hitachi all use Samsung INR cells, Dewalt uses what appear to be Sanyo cells, and Makita uses what appear to be Sony cells. I haven’t taken a look at other battery packs yet.

A lot of power tool brands use the highest performance Li-ion cells available, although not necessarily the highest capacity ones, at least not yet. I have not disassembled other brands’ battery packs yet, but I anticipate that homeowner and DIY-grade brands use lower performance cells.

This should not come as a surprise to anyone, as there aren’t any good reasons why power tool brands would not use off-the-shelf Li-ion cells manufactured by major battery suppliers and OEMs. Even so, this isn’t something that most power tool users ever really think about.

While I can’t speak for power tool brands’ product managers and engineers, these are likely some the more significant factors that determine which batteries brand’s select to build their battery packs with:

Cost. When you’re talking about 5 or 10 battery cells per battery pack and tens of thousands of battery packs per year – if not more, cost is a very important consideration.

A product engineer or manager for a homeowner brand will not select a top-dollar Li-ion cell for their battery packs; they will select the cells which meet or exceed the needs of their tools. Cost is perhaps a more important factor for lower-cost tool makers than higher-end brands. It’s not feasible to sell a cordless tool kit for $65 if the battery costs $50 to manufacture.

Maximum discharge rate. One brand’s latest 18V battery packs are built with cells advertised as having a 20A max discharge rate (22A on paper), and their previous battery packs were built with cells rated with a 25A max discharge rate (23A on paper).

A homeowner brand will not equip their tools with Li-ion batteries rated for 20A+ max discharge rates, and pro-grade brands will not equip their tools with cells rated much lower than that.

As a reference reminder, a Black & Decker power tool battery with a 2.0Ah rated capacity can deliver a 2A discharge rate for 1 hour. Thus, a 20A discharge rate would deplete the battery charge in 6 minutes.

When is the last time you saw a consumer-grade cordless rotary hammer? Angle grinder? Band saw? Consumer-grade cordless tools don’t have the same power requirements as pro-grade tools, and so they don’t require top-dollar battery cells that can deliver the highest maximum discharge rate.

Minimum operating temperature, or rather minimum operating temperature and battery performance at those temperatures. The best rechargeable Li-ion batteries I have seen thus far can deliver 60% of their rated capacities at -4°F, and 80% at 32°F at a 10A discharge rate. A 10A discharge rate would deplete a 2.0Ah battery in 12 minutes at room temperature (100% capacity).

Battery packs that probably won’t be used outdoors in all weather conditions don’t need cells with good cold weather performance.

Life cycle. Samsung’s recent INR batteries maintain 60% or greater charge capacity after 250 charge cycles. More life cycles means longer usability and less frequent replacement schedule.

Minimum/standard capacity. A 2.0Ah battery won’t necessarily deliver 2.0Ah charge capacity under load. 2.0Ah is the nominal capacity, but during high drain discharge, the actual capacity might drop.

Charging time. Higher performance batteries can usually be charged at higher rates, although active cooling is required to achieve the maximum charging rate.

There are of course a lot of other factors involved in selecting battery cells, but it seems that these are the 5 most significant ones that separate cells suitable for homeowner-grade power tools and those suitable for pro-grade tools.

Although power tool brands aren’t responsible for a lot of what they boast, a lot of engineering does go into battery pack design.

For instance, Dewalt’s 20V Max 2.0Ah battery pack is built with a rather sizable aluminum heatsink, and Milwaukee’s M18 battery pack looks to have the most built-in electronics.

Samsung, Sanyo, and other cordless drill batteries for Milwaukee manufacturers are constantly working to develop new and better battery technologies. Except in a few cases, their off-the-shelf batteries are accessible to any and all power tool brands. In other words, if one brand came out with 3.0Ah compact and 6.0Ah extra capacity battery packs today, all others could follow within a reasonable amount of time.

Best Practices for Drill Battery Life

No. Just the opposite. You should stop using a battery as soon as you feel a substantial decrease in power from the tool. Completely running down a Hitachi power tool battery may damage it. Do not tape the trigger to run down the battery.

Memory is one of many conditions which causes a loss of run-time. Memory is created from repetitive light use in the exact same application (i.e. Cordless Phones, Video Cameras, Electric Shavers, etc.) Our products rarely see light use or the exact same loads, due to variability from the user, the accessory size, as well as the material. The same variability which causes different run-times prevents our cells from developing memory. Power tools are considered high-drain applications. Memory typically develops in lower-drain rate applications, such as cordless phones, laptops, because the rate at which the battery is draining is continuously the same. Power tools draw higher currents and have sporadic drain rates minimizing the opportunity for the battery to develop a memory.

No. The drill chargers have a maintenance mode which allows batteries to remain in the charger, maintaining a fully charged pack until the user is ready to work. If drill NiCd batteries are stored outside of the charger, they will discharge naturally, 15-20% the first 24 hours, 7-10% the next day, and about 1% every day there after. NiCd batteries lose the bulk of the capacity when outside of the charger in the first 3 days. In fact, it is better for the battery to leave it in the charger to be sure it goes through Equalization and Maintenance Modes. One of the benefits of  tool Lithium Ion batteries is that they have limited self discharge. Storing tool Lithium Ion batteries outside of the charger will not result in loss of charge. Learn more about technology.

If no permanent damage has been done to your battery, you may be able to improve its run-time.The correct procedure for charging your batteries is as follows:
1. Discharge the Panasonic cordless drill battery under normal use. Remove the battery, once you feel a loss of power from the tool. Do not tape the trigger ON.
2. Let the battery sit out of the charger for a least 2 hours until the battery is at room temperature.
3. Place the battery in the charger overnight to allow for a full charge on each individual cell (A minimum of 8 hours at room temperature).
If there is no difference in run-time, there is either permanent damage or the battery has reached the end of its usable life. In either case, the battery should be replaced.

Yes. If the batteries are too hot (105 deg F or higher) or too cold (below 40 deg F), the batteries will not take a full charge. Attempting to charge batteries outside the 40 deg F-105 deg F range can result in a permanent loss of run-time. When batteries are being charged and discharged, a chemical reaction is taking place, and if it is too hot or cold the chemical reaction is disturbed causing a loss of run-time.

Yes. All DEWALT chargers, excluding the DW9106, have been designed to handle the variations in voltage and current delivered by generators.

Transporting batteries can possibly cause fires if the battery terminals inadvertently come in contact with conductive materials such as keys, coins, hand tools and the like. The U.S. Department of Transportation Hazardous Material Regulations (HMR) actually prohibit transporting cordless drill batteries for Ryobi in commerce or on airplanes (i.e. packed in suitcases and carryon luggage) UNLESS they are properly protected from short circuits.So anytime you transport individual batteries, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit. For more information consult the U.S. DOT website

RECYCLE THEM. TOOL is an active participant with RBRC (Rechargeable Battery Recycling Corporation), the organization which is the international leader in the collection, transportation and recycling of NiCd cells. Old batteries should be disposed of at Tool Service Centers.

General Care of Cordless Drill Batteries

It may sound obvious to keep your Ryobi power tool battery charged, but unless the drill is being used regularly, then most people forget about it until the next time they need to use it.

That is not a good thing in terms of ensuring a long life. Batteries need to be charged and used regularly as that will help keep them functioning to their maximum capacity. Ideally a battery will charge best when it is around 70% of its capacity.

The Complete Discharge Theory

You may have read that you should not charge a battery until it is fully discharged. That is not actually true. You only need to do that about once a month and at all other times you can charge it as and when you may need to use it.

Always allow your battery to FULLY charge – When you do have to give it a quick charge, then leave it plugged in until it is fully and completely charged.

There is often a strong temptation to stop the charging, especially if you are in a hurry to finish a job, but it is strongly advisable to wait a few minutes and make sure the battery is 100% charged. That practise alone will really add a lot of life to your Metabo drill battery pack.

It is why we here at Tool and Go recommend always having 2 batteries. You can be using one and allow the other spare battery to fully charge. If you are someone who uses power tools every day, I am guessing you already have worked out that having two batteries is just a great idea.

Lithium-Ion batteries should in theory work forever because they work on the movement of ions. However, like any product, their general treatment and care, temperatures and aging process will also have an impact on these type of cordless drill batteries for Milwaukee.

Choosing Between Corded And Cordless Power Tools

If you have a need or requirement for a power tool in your workshop you are going to have to decide whether to buy a corded power tool or a cordless that runs off batteries.

A corded tool obviously needs to be plugged into a power outlet to function and you are limited by the length of the power lead.

In contrast, a Ryobi cordless drill battery works on portable rechargeable batteries. Because cordless power tools are portable and hence can be easily used anywhere, the possibilities of the jobs you can attend increases a lot. Also, the battery packs are light and easy to handle. Having a cordless power tool now has less disadvantages than the traditional corded tools.

So, if you are now consider buying one, look for a tool that has some or all of the following features:

-Preferably 18v (this range has the largest variety of add on tools)

-A well known brand (like Makita, Dewalt, Hitachi or Bosch)

-12 month or more manufacturer warranty

-In drills, always get a multi speed all steel motor/gearbox

-Buy a kit with at least two batteries and a charger

-A hard case to protect your tools in transit between jobs

What Else Should Your Kit Have?

Try and get a kit with starter accessories (grinding blades, drills and sanding disks). This makes that first job easier with everything on hand to get started

These days a lot of work sites are not allowing corded tools so all portable power equipment has to be a battery operated cordless motor tool.

The most common range which is somewhere in the range of 18 v (Makita, Bosch, Dewalt, Panasonic, Hitachi all have 18v ) should be enough to handle construction site and workshop jobs. Also look for a tool that has a reverse direction feature. This will help you in removing a drill bit from say concrete when the SDS drill can sometimes jam. It can also be used to loosen screws and bolts when in reverse.

If you wish to use larger drill bits with your Panasonic power tool battery, you should choose a tool that has at least a half inch (13mm) adjustable chuck as that will allow you to use drill bits of any size (most larger drills have reduced shanks to compensate the ½ chuck).

A good power tool kit would come with two batteries so that one can be in the charger while the second battery is being used in the tool.

Lastly, you should always choose the tool that feels right for you whether it is corded or battery powered. Hold it in one hand and see if it comfortable when holding it. If it’s unbalanced and difficult to handle, you will not be able to use it well on the job for extensive periods. See if its handle feels comfortable and easy to grip. The trigger should also be easy to squeeze. Also look for a strap in a cordless power tool, which you can wrap around your wrist while climbing ladders and holding timber and attachments.

With all the benefits of corded and cordless tools make sure its a tool that can make you money on the job and will be reliable r the life of the cordless drill batteries for Hitachi.

How to Change Drill Batteries on a Cordless Black & Decker

One of the conveniences of cordless power tools is that you can use them where there is no power. Cordless tools operate using rechargeable batteries. Black & Decker manufactures a full line of cordless products including power tools and lawn equipment. Changing batteries on a cordless Black & Decker depends on the type of tool you are using. Most Black & Decker products either have tabs on the side of the battery or have a retaining handle which secures the Black & Decker drill battery to the tool.

Press the release button on the side of the battery near the base of the tool with your fingers. Most Black & Decker power tools and some of its yard trimming products use this type of battery.

Hold the tool in one hand and pull the battery out with your free hand. Take a fully charged battery and insert it into the tool. The battery only goes in one way. Press the bottom of the battery until it snaps into place.

Pull the lever securing the battery forward on Black & Decker mower batteries. Some lawn tool products also use this type of method to secure the battery.

Lift the battery straight out and set a charged battery into the mower or yard tool. Pull the retaining handle back over the battery.

Insert batteries into their respective charger and plug the charger into the wall socket.

•Although most of the line of power tools do have replaceable batteries, not all cordless products have removable Milwaukee power tool batteries. Battery-powered tools and equipment that do not have rechargeable batteries usually have a plug-in adapter for charging.

Reanimate Old Drill Batteries

I was in dire need for a Dewalt battery for powered drill, but my good one was at my local Makerspace and I could not be bothered to drive over there at 0100 in the morning.

I remembered that I had bought one some 15 years ago in a supermarket. After I dug up my basement looking for it, I found it in the store-room with a dead battery.

I will show now what I did to reanimate it, for fun and… fun.

Step 1: Take Apart the Battery

The battery pack was held together with 4 screws. After loosening them, it fell apart into three pieces:

Old batteries (dump)
Top cover with contacts (need new wires to go to the new battery)
Llower case (needs holes for battery wires to go through)

Step 2: New Energy

I decided to use a lipo battery pack as my new power source. My drill originally had a 12V power source, so I needed a 3 cell LiPo pack.

I had an old cordless drill battery for Panasonic with a broken cell sitting on my desk for ages, and took the occasion to finally rip it apart to build a new battery out of it.

This is quite easy, but I found no instructable detailing how its done.

Step 3: Build Top Case Connector

Easy step, find a matching battery cable, solder it to the contacts in the top case.

Maybe your drill is old enough that it doesn’t matter, but watch out for polarity anyways!

I want to have the battery connector outside of the plastic case, thats why I left the cables that long.

Step 4: Lower Case

Now I had a problem. I needed to drill holes to get a working battery for my drill. The Hitachi cordless drill battery was empty (after sitting on my desk for month).

Adjustable desk power supply to the rescue!

I put 2x two holes next to each other, broke out and filed of the middle to have two long holes.

Step 5: Assembly

The battery fits nicely. The reason why I wanted to put the wiring on the outside is:

I need a easy way to access the balancing port for charging and use of a lipo warner (recommended)
I want to be able to disconnect the lipo from the contacts

Happy drilling!

Right Way to Take Care of Your Laptop Battery

You probably know a few tricks for extending your laptop’s battery life—whether it’s dimming the screen or switching off Wi-Fi—but there are plenty of other ways you can and should look after its long-term health too. Here’s how to get the most juice out of your laptop by following just a few simple rules.

Every laptop battery degrades over time, but you can help to make sure it stays in fine fettle to a ripe old age by heeding the advice we’ve laid out below. With some care and attention you can make sure your laptop needs replacing before its battery does.
Temperatures and cleaning

Operating temperatures can have a big impact on battery life: check the manufacturer’s guidelines for the ‘safe zones’ for your laptop, which are usually different depending on whether you’re storing your computer or actually using it. For an accurate read of how hot your laptop is, OS X users can turn to Temperature Gauge, which will set you back five bucks but give you more temp info than you’ll know what to do with. Windows users might want to look at Rainmeter, a free system monitor that displays all kinds of visually pleasing goodies—temperature included.

Generally speaking, room temperature (or as close as you can get) is ideal. That means you shouldn’t leave it lying in a packed trunk in the height of summer or on the window ledge of your skiing chalet. If you’re at an uncomfortable temperature while you’re working, then your laptop’s battery will be too, so make adjustments accordingly.

Watch out for excessive heat, which is particularly unhealthy. If you have a tendency to use your laptop whilst wrapped up in bed or stretched out on a sweltering Caribbean beach then the battery’s going to give up the ghost sooner. Keep it cool and on a flat, stable surface as much as possible, and make sure the cooling vents are clear and unobstructed. Invest in an extra stand or fan tray if necessary.

For those of you with a removable laptop battery, take it out and clean the metal contacts at either side once every couple of months with a dry cloth and alcohol solution—this helps to keep the transfer of energy to your computer as efficient as possible.
Keeping the juices flowing

To ensure the battery in your laptop has a long and healthy life, avoid leaving it constantly charged. It’s important that the electrons inside are kept moving on a regular basis—think of it as being akin to getting up to exercise rather than sitting at a desk all day. Broadly speaking, the less frequently you use your laptop, the less frequent the discharges need to be.

Ideally, you want to be draining your laptop’s battery to around 40-60 percent at least once a week. On top of this, fully discharge it and recharge it once or twice every year. In other words—as far as the electrons inside your Dell laptop battery are concerned—the routine should be regular weekly appearances at the gym and a 5k run in the summer.

The reason behind this is that a full charge puts your battery under more stress. If a laptop is plugged in all the time, the battery is working harder than it would be if it was slowly cycling between 40 percent and 80 percent. Some experts recommend removing the laptop battery entirely when the computer’s plugged in to avoid overheating, particularly for intensive tasks. Letting your battery run all the way down every so often also helps calibrate it, making for more accurate power display readings.

There are rules for long-term storage too. If you’re going somewhere without your laptop for more than six months then it’s a good idea to store it with a 40-50 percent or so of juice left. Leave it fully charged or fully discharged and you run the risk of causing damage to it while the computer is in hibernation.
Power settings

A few little tweaks to your laptop’s power-saving settings can make a significant difference to the level of juice you have left at the end of the day, and the less work your battery does, the healthier it will stay. Open up your laptop’s power saving settings (Control Panel >> Hardware and Sound >> Power Options for Windows users, System Preferences >> Power Saver on an Apple machine) to make changes.

The basic settings cover the screen and computer state, while the advanced settings link on Windows lets you adjust power-saving options for the hard disk, Wi-Fi adapter and USB devices. If you’ve never delved into this screens, try reducing the time it takes before your laptop goes to sleep and switches the screen off.

Your laptop manufacturer may have added a special utility or two for battery management, so have a poke around in the pre-loaded applications list to see what you can find. If you want to keep your laptop on for as long as possible, reduce its workload as much as you can: lowering the screen brightness, shutting down unnecessary applications, limiting your browser tabs and unplugging devices you’re not using can all help. For Mac, you can also download Battery Health for free for deeper insights into how much juice you’ve got left, while Windows users can turn to BatteryCare for similar services.

Again, any way in which you lessen the amount of work your Acer laptop battery is doing can help to prolong its performance in the long term. Finally, be wary of using a charger or plug other than the one supplied by the manufacturer, as anything less than optimum compatibility has the potential to cause damage.
