Why an Optima BlueTop Deep Cycle Marine Battery is Better for Your Boat

Boats are hard on traditional lead-acid batteries. Their flat-plate design can’t handle the constant vibration and jarring from the waves. An Optima BlueTop Deep Cycle Marine Battery can handle the abuse. They are 15 times more vibration-resistant than the average lead-acid battery and rated for over 300 discharge/recharge cycles. The BlueTops can support high amperage loads when the engine is idling and alternator output drops, then recharge quickly when engine speed and alternator output increase.
