Product details
Positioned for the electric mobility sector, the EVX12650 belongs to CSB's EVX series and is a 12V Valve Regulated Sealed Lead Acid battery featuring a durable deep cycle pure lead design with a proprietary formulation. It utilizes AGM Absorbent Glass Mat technology with a gas recombination efficiency of up to 99%, combined with pure lead construction. This series primarily serves applications such as electric mobility and cyclic energy storage, and the official designated use of the EVX12650 is electric mobility.
In terms of capacity parameters, this battery has a nominal capacity of 65Ah (20hr-rate, 1.75VPC @25°C). At 25°C, discharging at 1.75VPC to the 8-hour rate delivers 59.36Ah, while the 20-hour rate corresponds to 66.20Ah; at 1.80VPC, the 8-hour rate is 58.24Ah. The maximum charge current is 19.50A, the maximum discharge current is 500A, the short circuit current reaches 1568A, and the internal resistance is only 4.6 mΩ. The equalization voltage range is 14.4 to 15.0 Vdc/battery (25°C).
Regarding construction: the EVX12650 is equipped with I2 threaded lead alloy terminals that accommodate M6 bolts, with a terminal torque of 51.7±10.3 Kgf·cm, equivalent to 44.9±9.0 Lbf·in, also equal to 5.10±1.0 N·m. The case is made of PP (UL 94-HB) material. It weighs 22.20 kg (48.89 lb), with dimensions of 349.4±2.5 mm in length, 166.0±2.0 mm in width, and 174.9±2.0 mm in height.
Regarding operating temperatures, the nominal value is 25°C (77°F); the allowable discharge range is -15°C to 50°C (5°F to 122°F), while charging and storage require -15°C to 40°C (5°F to 104°F). For design life, at 25°C, 100%DOD provides 400 cycles, and 30%DOD provides 1800 cycles. Self-discharge remains below 10% after 90 days of standing, and it can be stored for up to 6 months at 25°C; it must be fully charged before reuse, and if the storage temperature exceeds 25°C, charging is required earlier.
This battery is maintenance-free, manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008 standards, and is UL1989 certified (MH14533). With its deep cycle capability and pure lead construction, it is suitable for cyclic application scenarios such as electric mobility that require continuous charge and discharge.
