Sealed VRLA (Valve Regulated Lead Acid) means a battery that’s perfect for people who have better things to do than battery maintenance! Our permanently sealed VRLA battery never needs refilling; however, it still needs periodic charging. Ideal for motorcycles, scooters, ATVs, riding mowers and personal watercraft. Spill-proof design means virtually no possibility of leaks Advanced lead-calcium technology pumps up starting power Sulfation retardant dramatically reduces battery-killing plate sulfation And, sealed VRLA batteries hold voltage longer and need less charging in standby or storage mode Selected types also available in Factory Activated (filled, sealed and charged at the factory)
