Product details
EVX12300 is a 12V valve-regulated sealed lead-acid battery in CSB's EVX series. Internally, it uses a pure lead structure and AGM absorbent glass mat separators, and its gas recombination efficiency can reach 99%. The series is positioned as a durable deep-cycle battery for e-mobility and cyclic energy storage; the official application field is E-Mobility.
For temperature conditions, the nominal temperature is 25°C; discharge can be performed from -15°C to 50°C, while both charging and storage ranges are -15°C to 40°C. In terms of self-discharge, after 90 days at 25°C, self-discharge is less than 10%; the battery can be stored for up to 6 months and must be fully charged before use. If the storage ambient temperature is above 25°C, charge it earlier. The design life is 400 cycles at 100%DOD and 1800 cycles at 30%DOD at 25°C.
For dimensions, the EVX12300 is 166.0±2.0mm long, 125.0±1.5mm wide, and 175.0±2.0mm high, with a weight of 10.40kg (22.92 lb). The terminal is I1 type, accepts M5 bolts, and the terminal torque is 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in, or 3.0±0.6 N·m. The case uses ABS material with a flame retardant rating of UL 94-HB.
For capacity and electrical characteristics, at 25°C and 1.75VPC, the 20-hour rate nominal capacity is 30Ah, and the 8-hour rate capacity is 24.96Ah; at 1.80VPC, the 8-hour rate capacity is 24.32Ah. Maximum charge current is 9.00A, maximum discharge current is 400A, short-circuit current is 905A, and internal resistance is 7.9mΩ. The equalization voltage at 25°C is 14.4 to 15.0Vdc/battery; the data does not provide a float charge voltage.
For certifications, the battery is manufactured according to IEC 60254-1:2005 and IEC 60254-2:2008 and is UL1989 recognized (MH14533). Its maintenance-free design and deep-cycle characteristics make it suitable for e-mobility and cyclic energy application scenarios.
