                                      Using tips                                        

1.Battery Storage - Store your laptop battery in a clean, dry, cool place away from heat and metal objects. These latpop 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.

4.Charge and discharge - For lithium ion batteries, you do not need to discharge them fully and recharge constantly. You need to do a full discharge only about every 30 charges.

5.Do not charged to higher voltages than its threshold voltage

6.Do not short-circuit. A short-circuit may cause severe damage to the battery.

7.Consider removing the battery from a laptop when running on fixed power.

8.Avoid propping your laptop on a pillow, blanket, or other soft surface that can heat up. Your battery is a lot less efficient when not within its standard operating temperature range.
