Our group 34 marine battery is rugged, powerful, resilient, and should be the only battery you rely on for cranking, igniting, and lighting.

The advantage of buying Banshee Marine Batteries is that they have more battery plates. More battery plates mean more plate surface area. That means that the Banshee battery has more power – twice as much as conventional batteries.

Banshee batteries are capable of providing engine cranking As good as any other battery equally sized, even at very low temperatures. And they can handle 400 charge-discharge cycles to 80% depth of discharge.

Enhanced Flooded Battery or increasingly referred to as EFB technology in the market can not be installed on its side or upside down. EFB batteries are an enhanced version of standard wet-flooded technology. The primary benefits of EFB technology are improved charge acceptance and greater cyclic durability when operating in a reduced state of charge (typical of Stop Start applications).
