Mighty Max ML35-12GEL 12V 35AH GEL Battery — Replacement for Apollo 3500-1K Swing Gate Operator

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery from Mighty Max, offered as a replacement option for Apollo 3500-1K swing gate operators. It’s built for dependable service and long standby life when compared with comparable battery types. Lower self-discharge than AGM: The GEL construction reduces self-discharge relative to AGM batteries, so the unit holds charge longer during periods of inactivity — an advantage for backup or seasonal use and a strong reason to consider it as an upgrade. Reliable across temperatures: This GEL battery maintains consistent output in a wide range of climatic conditions. Its design helps it tolerate temperature swings, providing steady power whether used in summer heat or winter cold. Rugged design and improved safety: A thick, non-spillable gel paste minimizes the chance of leaks and harmful fumes, and the sealed construction increases resistance to vibration and shock. Those safety and durability features make it suitable for demanding installations. Proven brand performance: Mighty Max has a reputation for quality and reliability. The ML35-12GEL leverages GEL technology to deliver improved discharge characteristics, enhanced safety, solid performance, and a longer service life.
