Q: How to store the Panasonic CF-NX4 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 Panasonic CF-NX4 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 Panasonic CF-NX4 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 Panasonic CF-NX4 battery?
1Please fully charge your laptop before using it for the first time. Because the Panasonic CF-NX4 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 Panasonic CF-NX4 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.
