Product details

The EVP44-12EVR battery integrates industrial-grade performance into everyday applications, with its core value lying in balancing high-power output and ultra-long service life. The battery employs a triple-layer plate paste coating process combined with AGM separator technology, achieving over 95% electrolyte absorption rate. Even under high-frequency deep discharge (DOD 50%) conditions, it maintains a cycle life of 1,700 cycles. Medical device users can rely on its instantaneous discharge characteristic of 27.5Ah/30-minute rate to ensure uninterrupted power for life support systems, while wheelchair users benefit from the enhanced mobility offered by its lightweight 15.5kg design.Telecom base station maintenance personnel particularly favor the product's wide temperature adaptability (-15℃~45℃), which ensures stable 37.4Ah/5-hour rate power output even in extreme environments. The innovative three-dimensional sealing structure allows full closure of six filling holes, coupled with flame-retardant pressure relief valves to achieve IP55 protection grade, completely eliminating acid leakage risks. Technical specifications show an energy density of 28Wh/kg, and its compact 7.76-inch length enables flexible integration into small equipment like lawn mowers. User test data indicates only 12% capacity degradation over 3 years under daily charge-discharge cycles, validating its reliability certified by "Eurobat General Standards".The multi-directional installation feature (except inverted) provides installation flexibility for sports equipment like golf carts, while the B2 terminal's reverse-connection prevention design effectively reduces operational errors. These details collectively build the product's core competitiveness in emergency power applications.
