Lower self-discharge than AGM: The GEL construction reduces self-discharge compared to AGM batteries, so these cells hold their charge longer when left idle — an excellent upgrade choice for standby systems. Reliable across temperature extremes: Engineered to maintain steady output in a wide range of climates, these GEL batteries tolerate temperature fluctuations and deliver consistent power whether operating in hot summers or cold winters.
Built tough with added safety: A thick, non-spillable gel paste minimizes the chance of leaks and reduces harmful acid fumes, while the sealed design improves resistance to vibration and shock for use in demanding environments.
Trusted brand quality: Manufactured by Mighty Max, these GEL batteries combine improved discharge characteristics, enhanced safety, dependable performance, and extended service life.
