Should the battery be recharged in the meantime?

If you charge your battery at moderate temperatures while es is below zero degrees outside, the battery management system (BMS) ensures that the charging process is monitored. Es not only checks the self-discharge, but also detects potential risks to the cells, such as the risk of overcharging. When the battery reaches 100 percent, only trickle charging is activated - further "continuous charging" therefore brings you no benefits, but rather dangers and unnecessary electricity costs. The greatest danger is an electrical fire, which can be caused by a fault in the socket or the charger. You should therefore disconnect the battery from the charger in good time and only check the charge status after around three months. If necessary, you can then recharge it.
