Product details
The CSB EVX12300 is a 12V valve-regulated sealed lead-acid battery in the EVX series, utilizing AGM absorbed glass mat technology with a maximum gas recombination efficiency of 99% and a pure lead construction. This series focuses on durable deep cycle performance, designed specifically for e-mobility and cyclic energy storage scenarios, with the official listed application being E-Mobility.
In terms of capacity, at 25°C and 1.75VPC, the EVX12300 delivers a 20-hour rate nominal capacity of 30Ah and an 8-hour rate capacity of 24.96Ah; under 1.80VPC conditions, the 8-hour rate capacity is 24.32Ah. The maximum charge current is 9.00A, the maximum discharge current is 400A, the short-circuit current is 905A, and the internal resistance is 7.9mΩ. The equalization voltage should be set between 14.4 and 15.0Vdc/battery (25°C); float voltage is not mentioned in the documentation.
In terms of dimensions and construction, the battery measures 166.0±2.0mm in length, 125.0±1.5mm in width, and 175.0±2.0mm in height, weighing 10.40kg (22.92 lb). It features I1 type terminals suitable for M5 bolts, with a terminal torque of 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in, or 3.0±0.6 N·m. The case is made of ABS material with a flame retardant rating of UL 94-HB.
Temperature conditions: nominal temperature 25°C; discharge can be performed between -15°C and 50°C, while charging and storage are limited to -15°C to 40°C. Regarding self-discharge characteristics, at 25°C after 90 days of rest, self-discharge is less than 10%, with a maximum storage of 6 months; a full charge is required before use. If storage temperature exceeds 25°C, an earlier recharge is necessary. The design life at 25°C is 400 cycles at 100% DOD and up to 1800 cycles at 30% DOD.
Manufacturing standards are based on IEC 60254-1:2005 and IEC 60254-2:2008, and the battery is UL1989 recognized (MH14533). Its maintenance-free design and deep cycle capability make it suitable for e-mobility and cyclic energy applications.
