Product Details

Upgrade for a standard Group 48 size battery.

Lead-Acid batteries can be a pain. If they leak, holes can be eaten away in the battery tray and surround panels. In addition, you can only expect a relatively short life-span from them, a few years at most. Braille Battery offers their Endurance Advanced AGM batteries to eliminate this problem altogether, while simultaneously increasing power delivery and life-span with zero maintenance required! The Group 48 B7548 Endurance AGM battery from Braille features exclusive AGM internal racing technology from Braille, weighs roughly the same as a stock battery, and increases the Pulse Cranking Amps to 2390 and offers a 75 Amp Hour (AH) capacity. This means that the B7548 battery provides the highest cranking power and longest run times in its class!
