Our Mobile Power Center can be stored from 0°F to +140°F at up to 80% relative humidity. However it is best stored below 68°F in a cool, dry, well-ventilated facility free from corrosive gas or vapor. Storage at elevated temperatures (above 110°F) will degrade battery performance and reduce battery life. Storage at low temperatures may affect initial battery performance. Extended storage may require a few regular operating cycles to restore full accuracy to the fuel gauge.
Storing any lithium-ion battery, including the lithium-ion battery inside our Mobile Power Center, in a fully charged state for an extended period of time (i.e. over 10 days) will degrade battery performance and reduce battery life. Similarly, storing any lithium-ion battery in a fully discharged state for an extended period of time will also degrade battery performance and reduce battery life. Therefore, when storing your Mobile Power Center for extended periods, we recommend maintaining a state of charge between 30-70%. This will help maximize battery performance and increase battery life. Also, we recommend fully cycling (i.e. fully charging and discharging) the Mobile Power Center at least once every six months (and then recharging to 30-70% if storing) to maximize battery performance and increase battery life.
