When you use the Rechargeable laptop battery ,please note the following points:
1.Battery Storage - Store your laptop battery in a clean, dry, cool place away from heat and metal objects. These laptop batteries will self-discharge during storage; remember stored at about 40% state-of-charge.
2.Exercise Your Battery - Do not leave your battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery break in procedure described above.
3.Calibrate Your batteries - If your battery's 76% even less in work , you must fully charge, fully discharge, and then fully recharge the laptop battery pack.
