Like all rechargeable cells, laptop and notebook batteries eventually lose their ability to hold a charge. Even though Lithium-ion batteries are not affected by "memory effect," every battery has a limited number of charge cycles. The good news is, there are a few things notebook owners can do to maintain and prolong the life of their portable computer battery packs.
Take the
Acer laptop batteries 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 in your operating system's task bar.) Store the
IBM laptop batteries in a cool, dry place away from direct sunlight.
Use the notebook until the power runs down before charging it again (the Power/Standby light will blink and/or an alarm will sound). This minimizes the number of charge cycles, which will prolong the life of the battery.
Set your operating system's power options 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
Lenovo laptop batteries 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.
