Mighty Max ML35-12GEL 12V 35AH GEL NB Replacement Battery — Compatible with Roma Sirocco Powered Wheelchair, 4-Pack

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance free battery. Sold as a pack of 4, these batteries are designed as direct replacements for applications such as the Roma Sirocco powered wheelchair. Reliable charge retention: Gel chemistry in these batteries exhibits a slower self-discharge rate compared to AGM batteries, so they hold their charge longer when left unused — an excellent upgrade for devices that sit idle between uses. Performance across temperatures: Mighty Max GEL batteries are built to deliver steady power in a wide range of climates. Their construction helps maintain reliable output through both hot summers and cold winters, resisting performance loss from temperature swings. Rugged, safe construction: Each battery contains a thick, non-spillable gel paste that reduces the chance of leaks and minimizes hazardous fumes. The sealed GEL design also offers increased resistance to vibration and shock, making them suitable for demanding, mobile environments. Proven brand and longevity: Mighty Max has a strong reputation for dependable batteries. These GEL units offer improved discharge behavior, enhanced safety features, consistent performance, and an extended service life compared with many conventional lead-acid options.
