DRY batteries are lead acid flooded batteries. These batteries need to be filled before first use. DRY High Perfomance batteries include a sulfation retardant technology which reduces battery-killing plate sulfation. This results in a longer battery life, especially in standby or storage mode. These batteries are perfectly suitable for motorcycles, scooters, ATVs (Ali Terrain Vehicles), UTVs (Utility Vehicles), watercraft, snowmobiles and lawnmowers.
