Power Thunder Battery 53030

Conventional BMW 12-volt batteries reinforced with maintenance that use a specific lead to limit self-discharge and improve starting power. • Sturdy fiberglass to withstand vibrations • The special fine separator contains additional plates and provides up to 30% more starting power. • The intercell connector across the wall minimizes internal resistance and optimizes power • The Sulphate Stop function reduces plate sulfation and extends battery life. We recommend a motorcycle battery charger or battery regulator to prolong the life of your battery.
