ML12-12GEL 12V 12AH GEL F2 Replacement Battery for Sunl E-21 — Pack of 3

ML12-12GEL is a maintenance-free, rechargeable 12V 12AH GEL battery sold in a pack of 3. Its gel construction features a thick, non-spillable paste that minimizes leakage and lowers the risk of acid spills and corrosive fumes. That sealed design also helps the batteries withstand vibration and shock, making them suitable for tougher, high-vibration applications. Compared with AGM batteries, these GEL cells have a slower self-discharge rate, so they hold their charge longer when left unused — a practical upgrade for longer storage life. Mighty Max GEL batteries are engineered to perform reliably across a wide range of temperatures, resisting fluctuations so they deliver steady power in both hot summers and cold winters. Backed by Mighty Max’s reputation for quality and dependability, this GEL technology provides improved discharge characteristics, greater safety, consistent performance, and an extended service life.
