Sealed Motorcycle Batteries

For minimum maintenance, sealed motorcycle batteries feature gas recombination technology, which permits the battery to be resealed after it is filled with acid. In addition, special negative plates never give off gas during normal charging conditions. The result? Virtually maintenance-free batteries that never spill and damage your equipment! Plus, these batteries require fewer charges and last longer.

Unsealed Motorcycle Batteries

For Maximum Starting Power and Easy Maintenance, Unsealed Motorcycle Batteries feature advanced separator and through-the-partition construction to shorten the current path and reduce resistance. The result? Boosted cranking power. Battery staying power is increased too: a special lead/calcium alloy reduces shelf discharge and maximizes staying power, even after months of storage.
