How to Maintain a Notebook Battery

Like all rechargeable cells, laptop and notebook batteries eventually lose their ability to hold a charge. Although the Lithium-ion batteries does not always get affected by "memory effect," all battery has a designed limited number of charge cycles. You will be elated to know, there are a some simple tricks for maintaining and prolonging the life of a portable computer battery packs.

Take the battery out when the notebook is plugged in. Heat is one of the biggest detriments to the health of battery cells. Since laptops are usually set to run at full power when plugged in, the extra heat generated will eventually diminish the life of your battery.

Drain the battery pack to about 45 to 50 percent before removing it for extended storage. (Check the battery monitor Cmos battery buy in your operating system's task bar.) Store the battery in a cool, dry place away from direct sunlight.

Try as much possible to drain the power on the notebook before charging it again (the Power/Standby light will blink and/or an alarm will sound). This in return, reduces the number of charge cycles, which will at the same time prolong the life of the battery.

Setting the power options of your operating system to maximize battery life. In Windows XP, for example, click on the "Start" menu, then "Control Panel," "Performance and Maintenance," "Power Options," and then "Power Schemes." Select "Portable/Laptop," then click "OK."

Restart the computer and enter the BIOS (usually by pressing the "F1," "F2" or "Delete" key). Most newer notebooks have advanced BIOS features that control the amount of power used by internal components like the CPU. Set the power options to maximize battery life (refer to your owner's manual if necessary).

Buy an additional backup battery to increase the mobility of your notebook. Keep it fully charged if you use it on a regular basis. If not, follow Step 2 above to charge and store it safely.

How to Use a Notebook Battery

A notebook battery gives room for the notebook computer to be able to function even when it is not being plugged in into an electrical outlet. With this, the notebook gets more portability and mobility. To use a notebook battery, a user must install it and charge it, as the battery will eventually lose all of its charge if not plugged in to an electrical outlet. A battery can only be charged a certain number of times before it will not hold charge at all anymore and need replacing.

Turn the notebook computer over so the bottom is facing up.

Insert the HP 462889-121 battery into the slot. The battery can be inserted only one way, and the side that is opposite the battery latch should go in first. The Compaq 367759-001 battery can then be pushed down to snap it into place. Insert the AC power adapter into the back of the notebook to charge the Dell W953G battery and plug it into an electrical outlet. The battery will charge regardless of whether the notebook is on or not. When the battery is fully charged, the notebook can be unplugged to run on battery only.
