Power Thunder 53030

Conventional BMW batteries with 12 volts are reinforced and maintenance-free, using a special lead that limits self-discharge and improves starting power. Robust fiberglass withstands vibrations. The special fine separator accommodates additional plates and provides up to 30% more starting power. The intercellular connection through the wall minimizes internal resistance and optimizes performance. The sulfate stop function reduces plate sulfation and extends lifespan. We recommend using a motorcycle battery charger or a battery regulator to prolong the life of your battery.
