FAQ - How to make your Acer BTP-52EW battery last longer?

1. Should I totally discharge and recharge my Acer BTP-52EW battery occasionally to make it last longer?
   A: No, discharging and charging does not increase the life of a lithium ion Acer BTP-52EW. 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 BTP-52EW battery last longer:
   - Choose the right battery. Under the same use conditions, a lower capacity battery will wear out faster than a higher capacity battery because it has to be charged more often.
   - 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. What do we recommend for Acer BTP-52EW battery storage for a long period of time?
   A: When storing for more than 4 days these guidelines can better preserve the life of your battery:
   - Do not store Acer BTP-52EW battery for long periods plugged into or attached to any power source. This includes AC adapters and laptop security carts plugged into an outlet.
   - Acer BTP-52EW batteries, including those stored in laptop systems, should maintain an Operational Storage Temperature of 0° to 35°C (32° to 95°F).
   - Batteries may be stored in the laptop or outside of the laptop.
   - Charge batteries before storing. The recommended charging time should not exceed 1 hour. Typically, this should charge the Acer BTP-52EW batteries to between 80% and 100%. (Some discharge will take place over time. Stored batteries are expected to discharge 10-15% over a four month period, for your information.)
4. Any other tips of using Acer BTP-52EW battery?
   A: Keep the Acer BTP-52EW battery cool, dry and clean after been fully charged. Don't short circuit terminal or store your Acer BTP-52EW battery pack with metal parts.
