FAQ - How to extend your Acer Aspire 1640 battery life?

1. Should I totally discharge and recharge my Acer Aspire 1640 battery occasionally to make it last longer?
   A: No, discharging and charging does not increase the life of a lithium ion Acer Aspire 1640. And with current lithium ion batteries this practice does not improve the runtime of the battery. This practice is a holdover from the days in which NiMH batteries were used.
2. What can I do to make my battery last longer?
   A: There are several things you can do to make your Acer Aspire 1640 battery last longer:
   - Use the notebook's power saving controls to reduce battery use in your normal day. For example, turn the Bluetooth off if it is not needed; reduce the screen brightness when conditions permit.
   - Avoid exposure to extreme temperatures. If the system is exposed to extreme cold or hot temperatures, allow it to warm up/cool down before use and before charging.
   - Contrary to last decades' batteries, modern lithium ion batteries do not need to be fully discharged to maintain health.
   - All batteries wear with use and time. When you find the runtime is no longer satisfactory, it may be time to purchase a new Dell battery.
3. Will my Acer Aspire 1640 battery become useless if I leave it unused for a long time?
   A: Basically, yes. We suggest you to charge or discharge the Acer Aspire 1640 laptop battery to 40 - 60% capacity using your Windows operating system power meter, then remove it from your system.
