Mighty Max ML35-12GEL 12V 35AH GEL NB Replacement Battery — Compatible with Invacare Pronto M51, M61

ML35-12GEL is a 12V 35AH GEL rechargeable maintenance free battery designed as a replacement for Invacare Pronto M51 and M61. Its GEL chemistry offers a lower self-discharge rate than AGM batteries, so it retains charge longer in storage and is an excellent upgrade option for longer standby times. Built to deliver steady, long-lasting power across a wide range of temperatures, these GEL cells perform reliably in both hot and cold conditions. The battery uses a thick, non-spillable gel paste that minimizes the risk of acid leaks and fumes while improving resistance to vibration and shock—making it well suited for rugged or mobile applications. Backed by Mighty Max’s reputation for quality, this model provides improved discharge characteristics, enhanced safety, dependable performance, and extended service life.
