Mighty Max ML35-12GEL 12V 35AH GEL NB Replacement Battery for Heartway Rumba HP3, HP3HD, SR P4R - 2 Pack

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery sold as a 2-pack. Designed as an NB replacement compatible with Heartway Rumba models HP3, HP3HD and SR P4R, this battery provides dependable power for mobility and other applications. Longer charge retention: The GEL design features a slower self-discharge rate compared to AGM batteries, so these cells hold their charge longer when stored or unused. That translates to more reliable readiness between charges. Built for harsh environments: Mighty Max GEL batteries deliver consistent output across a wide temperature range and are engineered to tolerate extreme conditions and temperature fluctuations without compromising performance. Safer, rugged construction: Each unit uses a thick, non-spillable gel paste that minimizes the risk of acid leaks and harmful fumes. The gel construction also improves resistance to vibration and shock, making these batteries suitable for demanding, mobile use. Proven reliability: Backed by Mighty Max’s reputation for quality, the ML35-12GEL offers advanced GEL technology with superior discharge characteristics, enhanced safety features, solid performance and a longer service life.
