Product details
The CSB EVX12650 belongs to the EVX Series and is a 12V valve-regulated lead-acid battery featuring AGM absorbed glass mat technology for up to 99% gas recombination efficiency, along with pure lead construction and a proprietary formulation. This series is positioned as a durable deep-cycle pure lead battery for e-mobility and cyclic energy storage applications, and the official application area of the EVX12650 is e-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 at 1.75VPC corresponds to 59.36Ah, the 20-hour rate at 1.75VPC corresponds to 66.20Ah, and the 8-hour rate at 1.80VPC corresponds to 58.24Ah. The battery's maximum charging current is 19.50A, maximum discharging current is 500A, short-circuit current is 1568A, and internal resistance is 4.6 mΩ. The equalizing charge voltage is 14.4 to 15.0 Vdc/battery (25°C).
Structurally, the EVX12650 uses I2 threaded lead alloy terminals that accept M6 bolts, with a terminal torque of 51.7±10.3 Kgf·cm or 44.9±9.0 Lbf·in or 5.10±1.0 N·m. The case material is PP (UL 94-HB). The weight is 22.20 kg (48.89 lb), and the dimensions are length 349.4±2.5 mm, width 166.0±2.0 mm, height 174.9±2.0 mm.
Regarding operating temperature, the nominal temperature is 25°C (77°F), the discharge range is -15°C to 50°C (5°F to 122°F), and the charge and storage range is -15°C to 40°C (5°F to 104°F). The design life is 400 cycles at 100%DOD and 1800 cycles at 30%DOD at 25°C. Self-discharge is less than 10% after 90 days, and the battery can be stored for up to 6 months at 25°C; it must be fully charged before use, and should be charged sooner if stored above 25°C.
This battery is maintenance-free, manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008, and recognized under UL1989 (MH14533). Its deep-cycle characteristics and pure lead construction make it suitable for cyclic applications such as e-mobility that require repeated charging and discharging.
