ML35-12GEL 12V 35AH GEL NB Replacement Battery — Compatible with UPS 33Ah Werker WKA12-33J

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery designed as a GEL NB replacement compatible with UPS 33Ah Werker WKA12-33J. Its gel chemistry yields a slower self-discharge than AGM batteries, so it retains charge longer when stored and is a strong upgrade for standby applications. Formulated to deliver dependable power across a wide temperature range, Mighty Max GEL batteries perform reliably in both hot summers and cold winters. The sealed design contains a thick, non-spillable gel paste that reduces the risk of leaks and fumes and increases safety; this robust construction also helps the battery withstand vibration and shock in rugged conditions. Backed by Mighty Max’s reputation for quality, the ML35-12GEL offers superior discharge behavior, improved safety features, consistent performance, and an extended service life.
