A Laptop Battery Guide : How To Do Better For More Battery Life

For a laptop battery user, we should know Laptop Battery Basics :

Take care of your laptop battery and ensure that it will be ready to work properly when you need it most. Some general tips for laptop care include: avoid extreme temperatures, dont leave a laptop outside in cold weather or leave it in a hot car. Cold batteries cant create very much power and hot batteries will discharge very quickly. Use electrical power when available to keep battery charged. Dont let your laptop go for long periods of time without using the battery.

Ni-Cad (Nickel Cadmium battery), and Ni-MH (Nickel Metal Hydride) were once highly used having 1.2 Volts per cell.

Li-Ion (Lithium-ion) have now taken their place having 3.6-3.7 Volts per cell and are much more practical for todays power hungry notebooks. They have more power, higher voltage, less self drain, less weight, and can be smaller for the power you get. You will also not find the memory problems previous batteries were known for. I guess the only drawback is theyre more expensive.

Smart/dumb batteries

You will find most if not all of todays notebooks use Li-Ion smart batteries. The fact that its smart means it has circuits that report its charge level so you can estimate the battery life remaining or when its about to run out.

Batteries are over-all measured in mAh (Milliamps/hour)

There are many things you can do to increase your battery life at the cost of performance, comfort, and features. What many will do that need to maximize their battery life for example if theyre going on a trip, is get their settings in order before heading out. Heres a few things you can do:

Adjust LCD brightness

Most notebooks will be set to dim the LCD automatically by default from the factory. Unplug your system to check the brightness to verify. Some will do it over a few seconds slowly so you dont notice it so you have to watch carefully. If you feel you could deal with the display being even more dimmed, then (Windows) right click your desktop background, go to Properties, then click the Settings tab at the top. Click Advanced and you will often find your settings for brightness in there which can vary depending on the graphics chipset and software on your system. Sometimes you can find the graphics control panel or settings hot link in your lower right hand system tray depending on software.

Turn it down to whatever youre comfortable with. The LCD is one of the biggest battery hogs most laptops face keeping fed.

So try to know more information about your laptop batteries and keep it used longer.
