Supernova B54 Battery Pack black

The optimal charging temperature of a battery is about 20°C. Therefore, in the high-tech battery, as in a modern electric car, an integrated battery heater ensures the optimum charging temperature when it is too cold. If the temperature exceeds 40°C, charging is automatically prevented until the temperature has dropped again.

All you have to do is activate the fully automatic Longlife mode for more than 50% of the service life and ensure that the battery is not left fully charged in a hot car for a long time, for example. Even without using the Longlife mode, Supernova still gives an exceptional 3-year warranty.

The Longlife mode ensures a particularly long service life of the battery cells. Through
special processor-controlled charging, this mode prevents any overheating of the cells during the charging process. The battery is only charged to 85% in this mode, which extends the service life.

If you do not use the battery for a longer period of time, you can simply put it into hibernation mode. It is then kept at optimum voltage on the charger. This stops the chemical aging of the battery almost completely. Deep discharge is prevented.
