How to extend the life of your Dell WY9DX battery?
1.Please fully charge your device before using it for the first time. Because the Dell WY9DX battery is normally shipped in a partially-charged state. Please cycle your battery pack by fully charge (more than 12hours) and discharge(less than 10%) for 3-5times to reach maximum rated capacity.
2.Please don’t discharge battery to 0%, which is the most common reason among faulty batteries. It will damage battery if the device usually works at a critical power level ( below 3%).
3.Charge the battery before it runs to 20%. It is scientifically justified that charging battery at 20% till 80% will extend battery life to the longest.
4.If your Dell WY9DX battery won’t be used for a long time, please charge it once a month and keep battery power over 50%, remove it from your device and store it in an antistatic bag in a cool, dry place.
