These guidelines can better preserve the life of your battery:
1. Do not store batteries for long periods plugged into or attached to any power source. This includes AC adapters and laptop security carts plugged into an outlet.
2. Laptop batteries, including those stored in laptop systems, should maintain an Operational Storage Temperature of 0° to 35°C (32° to 95°F).
3. Batteries may be stored in the laptop or outside of the laptop.
4. Charge batteries before storing. The recommended charging time should not exceed 1 hour. Typically, this should charge the battery 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.)
No, discharging and charging does not increase the life of a Lithium Ion technology battery.
The charge time varies depending on the system. If the system supports ExpressCharge , the battery typically will have greater than 80% charge after about an hour of charging, and fully charge in about 2 hours with the system off.
