What do I need to consider when storing the battery?

Store the battery out of the reach of children and pets.
DO NOT store the battery near heat sources such as a stove or heater.
DO NOT leave the battery inside a vehicle on hot days. The ideal storage temperature is 22°C - 28°C.
Disconnect the charger when es is not in use.
DO NOT store the battery fully charged or discharged for a longer period of time. If you do not plan to use the e-Fin 2.0 within the next 4 weeks, make sure that the charge level is between 25% and 75%. Otherwise, the service life and performance may be reduced.
