Product details
The CSB EVX12650 in the EVX series is a 12V valve-regulated sealed lead-acid battery. It uses AGM absorbent glass mat technology, with gas recombination efficiency of up to 99%, and also features a pure lead construction and proprietary formulation. The series is positioned as a durable deep-cycle pure lead battery, serving electric mobility and cyclic energy storage applications; for the EVX12650 specifically, the official application area is electric mobility.
In terms of capacity, the EVX12650 has a nominal capacity of 65Ah (1.75VPC @25°C, 20hr-rate). At 25°C, the 8-hour rate capacity at 1.75VPC is 59.36Ah, the 20-hour rate capacity at 1.75VPC is 66.20Ah, and the 8-hour rate capacity at 1.80VPC is 58.24Ah. Its maximum charge current is 19.50A, maximum discharge current is 500A, short-circuit current is 1568A, and internal resistance is 4.6 mΩ; equalization voltage is 14.4 to 15.0 Vdc/battery (25°C).
The EVX12650 has dimensions of length 349.4±2.5 mm, width 166.0±2.0 mm, height 174.9±2.0 mm, and weight 22.20 kg (48.89 lb). Its case is made of PP (UL 94-HB) material; the terminal is I2 threaded lead alloy and can be fitted with M6 bolts, with a tightening torque of 51.7±10.3 Kgf·cm, which can also be converted to 44.9±9.0 Lbf·in or 5.10±1.0 N·m.
For temperature parameters, the nominal temperature is 25°C (77°F); the discharge temperature range is -15°C to 50°C (5°F to 122°F), and the charge and storage temperature range is -15°C to 40°C (5°F to 104°F). In a 25°C environment, the design life at 100%DOD is 400 cycles, and at 30%DOD is 1800 cycles. Self-discharge is less than 10% after 90 days; it can be stored for up to 6 months at 25°C and must be fully charged before use; if storage temperature exceeds 25°C, charge it earlier.
This battery features a maintenance-free design, is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008, and is UL1989 recognized (MH14533). The pure lead construction combined with deep-cycle characteristics makes it suitable for cycling applications such as electric mobility that involve repeated charge and discharge.
