Product details
The EVX series includes the CSB EVX12650, a 12V valve-regulated sealed lead-acid battery. This battery utilizes AGM absorbed glass mat technology with a maximum gas recombination efficiency of up to 99%, and features pure lead construction and a proprietary formulation. This series is positioned as a durable deep cycle pure lead battery suitable for electric mobility and cyclic energy storage applications, and the official application direction of the EVX12650 is electric mobility.
In terms of capacity, the EVX12650 has a nominal capacity of 65Ah at 25°C, 1.75VPC, 20hr-rate. Also at 25°C, when discharged at 8-hour rate, 1.75VPC, the capacity is 59.36Ah; at 20-hour rate, 1.75VPC, the capacity is 66.20Ah; at 8-hour rate, 1.80VPC, the capacity is 58.24Ah. The battery can withstand a maximum charging current of 19.50A, a maximum discharge current of 500A, a short-circuit current of 1568A, and an internal resistance of 4.6 mΩ. At 25°C, the equalization voltage range is 14.4 to 15.0 Vdc/battery.
Structurally, the EVX12650 is equipped with I2 threaded lead alloy terminals compatible with M6 bolts. The terminal torque is 51.7±10.3 Kgf·cm, or 44.9±9.0 Lbf·in, or 5.10±1.0 N·m. The case is made of PP (UL 94-HB) material. The battery weighs 22.20 kg (48.89 lb), with dimensions of: length 349.4±2.5 mm, width 166.0±2.0 mm, height 174.9±2.0 mm.
In terms of temperature adaptability, the nominal operating temperature is 25°C (77°F). The discharge temperature range is -15°C to 50°C (5°F to 122°F), and the charging and storage temperature range is -15°C to 40°C (5°F to 104°F). For design life, at 25°C, 400 cycles at 100%DOD and 1800 cycles at 30%DOD can be achieved. Self-discharge characteristics are less than 10% after 90 days, and it can be stored for up to 6 months at 25°C, requiring a full charge before reuse; if the storage temperature exceeds 25°C, it should be charged earlier.
This battery features a maintenance-free design, is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008 standards, and is UL1989 recognized (MH14533). Its pure lead construction and deep cycle characteristics make it suitable for cyclic application scenarios such as electric mobility that require frequent charging and discharging.
