Follow the notice below, Better using your Dell 3RNFD Battery
1.Storage - Store your Dell 3RNFD Battery in a clean, dry, cool place away from heat and metal objects. The Lenovo L18C3PD2 batteries will self-discharge during storage; remember stored at about 40% state-of-charge.
2.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. Do not charged to higher voltages than its threshold voltage.
3.Exercise Your 3RNFD Battery - Do not leave your batteries 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.
4.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.
5.Consider removing the 3RNFD battery from a laptop when running on fixed power.
6.Do not short-circuit. A short-circuit may cause severe damage to the battery.
7.Avoid propping your laptop on a pillow, blanket, or other soft surface that can heat up. Your Dell 3RNFD battery is a lot less efficient when not within its standard operating temperature range.
