Mighty Max ML35-12GEL 12V 35AH GEL Replacement Battery — Compatible with Neptune NT12-35 IT (4-Pack)

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery sold as a pack of 4 and designed as a replacement compatible with Neptune NT12-35 IT. Compared with AGM batteries, this GEL design has a slower self-discharge rate, so it retains charge longer when not in use — making it a strong upgrade choice. Mighty Max GEL batteries deliver reliable power across a wide temperature range, maintaining steady output in both hot and cold conditions and handling temperature fluctuations effectively. Constructed with a thick, non-spillable gel paste, these batteries are safer and less likely to leak, which reduces the risk of acid spills and harmful fumes. Their robust build also resists vibration and shock, making them suitable for demanding or mobile applications. Backed by Mighty Max’s reputation for quality, this GEL technology offers superior discharge characteristics, improved safety, consistent performance, and extended service life.
