How to Take Care of Your WT870 laptop Battery
Let the WT870 battery discharge completely the first time you use it. When you get a new Dell Studio 14 laptop, or just a new WT870 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 WT870 battery--essentially 'teaching' it how much charge it can hold.
Allow the WT870 battery to fully discharge about once every 30 cycles. This will help recalibrate the battery.
Avoid frequent charging and discharging. A typical lithium-ion WT870 laptop battery has a life of about 300 to 500 charge 'cycles'.
