Gel-Tech sealed marine batteries offer many significant advantages over conventional "flooded" batteries. Gel batteries are spill-proof and leak-proof, and resist over-discharges that can shorten the life of the battery.

Gel batteries have a self-discharge rate of less than 1 percent per month (at 68F). They provide ample cranking amperage for quick, sure starts, and deliver longer trolling time than comparable flooded models.

Their Sealed Valve-Regulated (SVR) design minimizes gassing, making them safe to install around people and sensitive electronic equipment. Gel batteries offer a viable alternative when you can only choose one battery.

Info & Guides

Charging:

For longest life, always use a good, constant potential, voltage-regulated charger. For 12-volt Gel batteries, charge to at least 13.8 volts, but no more than 14.1 volts at 68F (20C). Do not charge in a sealed container.
