Product details
The CSB EVX12300 battery belongs to the EVX series product line. It is a 12V Valve Regulated Sealed Lead Acid battery that uses AGM Absorbent Glass Mat technology internally, with a gas recombination efficiency of up to 99%, and is built with a pure lead structure. This series is defined as a durable deep cycle battery suitable for electric mobility and cyclic energy storage applications, with the official application direction being E-Mobility.
In terms of capacity data, at 25°C and 1.75VPC, the EVX12300 has a nominal capacity of 30Ah at the 20-hour rate and 24.96Ah at the 8-hour rate; if the condition is changed to 1.80VPC, the 8-hour rate capacity reaches 24.32Ah. The battery supports a maximum charging current of 9.00A, a maximum discharge current of 400A, a short-circuit current of 905A, and a measured internal resistance of 7.9mΩ. The equalization voltage should be controlled at 14.4 to 15.0Vdc/battery (25°C), while the float charge voltage is not given in the data.
Looking at the structural dimensions, the EVX12300 has a length of 166.0±2.0mm, a width of 125.0±1.5mm, a height of 175.0±2.0mm, and an overall weight of 10.40kg (22.92 lb). The terminal adopts the I1 type, which can match M5 bolts, and the terminal torque range is 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.
Regarding operating temperature, the nominal temperature is set at 25°C, the allowable temperature range during discharge is -15°C to 50°C, while charging and storage must be between -15°C and 40°C. In terms of self-discharge performance, after 90 days of storage at 25°C, self-discharge is less than 10%, and it can be stored for up to 6 months; it must be fully charged before reuse. If the storage temperature exceeds 25°C, it needs to be charged in advance. In terms of design life, at 25°C, 400 cycles can be achieved at 100% DOD, and 1800 cycles at 30% DOD.
This battery is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008 standards, and has also obtained UL1989 recognition (MH14533). The combination of maintenance-free design and deep cycle characteristics enables it to handle electric mobility and cyclic energy application scenarios.
