FAQs

Q: How to charge a new battery for Acer AP21A7T for the first time use?
A: New Acer AP21A7T battery pack is normally shipped in its partially charged condition. Please cycle your new AP21A7T battery pack by fully charge and discharge it for 3-5 times to allow it to reach its maximum rated capacity before use. (Note: it is perfectly normal for a battery to become warm to the touch during charging and discharging). New batteries are hard for your device to charge; they have never been fully charged and are therefore "unformed". Sometimes your device's charger will stop charging a new battery before it is fully charged. If this happens, simply remove the battery from your device and then re-insert it. The charge cycle should begin again. This may happen several times during your first battery charge. Don't worry; it's perfectly normal.
Q: The Acer AP21A7T battery has been installed several times, but device can't boot up?
A: Carefully check if interfaces of the device and the battery are correctly connected. If the cause of loose contact is ruled out, please contact the after-sales customer service to ensure that the battery part number and device model are matched.
Q: How to store the Acer AP21A7T battery if you won’t use it for a long time?
1.It is not a feasible way for you either fully charge or fully discharge battery if long term storage. Security risks will generate if under a fully charged state, while both cells and control circuit protection lock will be deactivated if under a fully discharged state. So you’d be better store the Acer AP21A7T battery at a half fully charged state and keep it in a cool, dry place. 20 degrees Celsius is the optimum storage temperature.
2.Install and run Acer AP21A7T battery as often as possible(at least once a month) so as to ensure its availability and avoid power drain.
Q: How to extend the life of your Acer AP21A7T battery?
1.Please fully charge your device before using it for the first time. Because the Acer AP21A7T 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 Acer AP21A7T 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.
