This state-of-the-art lead-acid battery is the valve-regulated type (often called sealed or maintenance-free), which fixes the acid electrolyte in a gel or in an absorptive fiberglass mat. The advantage of this design is that the battery needs no water additions, can be operated in any position, and can be used in close proximity to people and sensitive equipment. This battery offers heavy duty sealed no-leak design with no-corrosion terminals, higher cranking amps, lower self-discharge and greater vibration resistance. All of our batteries are factory fresh substitutes for the original OEM battery and are designed to meet or exceed the original batterys specifications.
