Mighty Max ML35-12GEL 12V 35AH GEL Battery Pack (4) — Replacement for J.C. Penney 931-5730

ML35-12GEL by Mighty Max is a 12V 35AH GEL rechargeable, maintenance-free battery sold as a 4-pack and engineered as a compatible replacement for J.C. Penney 931-5730. These GEL batteries exhibit a slower self-discharge rate compared to AGM types, so they retain charge longer during storage and provide more reliable power when needed. Designed to withstand a wide range of climates, they deliver consistent performance in extreme temperatures and tolerate thermal fluctuations for dependable operation in hot summers or cold winters. The cells use a thick, non-spillable gel paste that reduces the risk of leaks, minimizes acid spills and harmful fumes, and enhances overall safety. Gel construction also improves resistance to vibration and shock, making these batteries well-suited for demanding or rugged environments. Backed by Mighty Max’s reputation, this advanced GEL technology offers superior discharge characteristics, improved safety, better performance, and an extended service life.
