Why does the battery of my Stromer e-bike discharge itself?

Stromer E-Bike: Battery discharges itself

If you store your Stromer Speed Pedelec in anti-theft mode (locked mode), the anti-theft mode uses power and the battery will be empty after about 10 days. The anti-theft mode was developed to park the bike for a short time, for example while shopping. It is not suitable for monitoring the Speed Pedelec for an extended period of time. If it will be parked for a longer period, you should therefore switch off the bike and additionally secure it with a lock.

The battery management system (BMS) also consumes a small amount of power, slowly discharging the battery. If you do not use your bike for a longer period of time, we recommend connecting the bike to the charger CR246, which offers the option of a floating charge.

The floating charge automatically keeps the battery in the optimal charging range. This means that the charging process is stopped after a full charge until the charge level of the battery has fallen back to around 60 % after about 3 weeks. The charge level is then maintained at 65 – 80 % until the charger is disconnected from the battery.
