lenovo ThinkPad T420s SeriesHow to Take Care of Your 42T4847 laptop Battery
Let the 42T4847 battery discharge completely the first time you use it. When you get a new lenovo ThinkPad T420s Series laptop, or just a new 42T4847 battery, plug the computer in and charge the battery fully. Unplug the laptop and run it on battery power until the computer warns you that it's about to run out. This calibrates the 42T4847 battery--essentially 'teaching' it how much charge it can hold.
Allow the 42T4847 battery to fully discharge about once every 30 cycles. This will help recalibrate the battery.
Avoid frequent charging and discharging. A typical lithium-ion 42T4847 laptop battery has a life of about 300 to 500 charge 'cycles'.
