Vostro 2421 2521 Inspiron 14 (3421) 14r(5437) 15(3537) 17 15R 17RHow to Take Care of Your MR90Y laptop Battery
Let the MR90Y battery discharge completely the first time you use it. When you get a new Dell Vostro 2421 2521 Inspiron 14 (3421) 14r(5437) 15(3537) 17 15R 17R laptop, or just a new MR90Y 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 MR90Y battery--essentially 'teaching' it how much charge it can hold.
Allow the MR90Y battery to fully discharge about once every 30 cycles. This will help recalibrate the battery.
Avoid frequent charging and discharging. A typical lithium-ion MR90Y laptop battery has a life of about 300 to 500 charge 'cycles'.
