DO NOT store the battery near heat sources such as an oven 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 in use.
DO NOT store the battery fully charged or fully discharged for long periods of time. If you do not plan to use the e-Fin .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.
