- What is your expected running time by a battery pack ?
- Decide battery pack voltage you will choose
- Battery pack voltage must be equal or a little higher than your device’s need.
- Decide Battery pack’s Capacity ( mAh or Ah)
- Battery capacity is depended on how long you need to run your device ( hours ), which can be calculated as the follow:
- ( Ah) = Device’s Wattage (W) x Time to run ( Hours) / Battery Voltage (V)
- For example, if using a 12V battery pack, and run 10W DC device for 10 hours, you need choose a battery pack with capacity > 8.3Ah, e.g (10×10)/12 = 8.3

- Don’t use a screensaver. They’re unnecessary on modern displays and will drain your battery to do nothing useful when your display could be off and saving power.
- Run fewer programs in the background. Examine your system tray for programs you don’t need and uninstall them or disable them and prevent them from automatically starting with your computer.
- Reduce CPU usage. If you use heavy programs that have your CPU doing a lot of work all of the time, your CPU will use more power and your battery will drain faster. Running fewer programs in the background can help with this, as can selecting lightweight programs that are easy on system resources.
- Avoid maxing out your RAM. If your computer fills its RAM and needs more memory, it will move data to the page file on its hard drive, and this extra hard drive usage can drain battery. This shouldn’t be a problem on modern computers with a decent amount of RAM. If your laptop’s RAM is full, try to make more RAM available — close programs running in the background or even upgrade your laptop’s RAM.
