FAQs
Q: The IBM 41N5666 battery has been installed several times, but laptop can't boot up?
A: Carefully check if interfaces of the computer 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 laptop model are matched.
Q: How to store the IBM 41N5666 battery if you won’t use it for a long time?
1It 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 IBM 41N5666 battery at a half fully charged state and keep it in a cool, dry place. 20 degrees Celsius is the optimum storage temperature.
2Install and run IBM 41N5666 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 IBM 41N5666 battery?
1Please fully charge your laptop before using it for the first time. Because the IBM 41N5666 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.
2Please don’t discharge battery to 0%, which is the most common reason among faulty batteries. It will damage battery if the laptop usually works at a critical power level ( below 3%).
3Charge 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.
4If your IBM 41N5666 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 laptop and store it in an antistatic bag in a cool, dry place.
