Before putting it into winter storage, it is advisable to fully charge the battery with an external charger. To keep the voltage at a level above 12.5 V, the battery should also be connected to a compatible charger every two months. The maintenance charge prevents discharge, extends the life of the battery and guarantees an optimum charge level at the start of the season. For this, a special charger must be used, which includes a maintenance charge mode, as otherwise there is a risk of overcharging. In case of doubt, please consult the manufacturer’s information.
