Product details
The CSB EVX12400 belongs to the EVX series; its product type is a 12V Top Terminal VRLA-AGM battery, and its official application area is electric mobility. This series is positioned as a durable deep-cycle valve-regulated sealed pure lead battery series for electric mobility and cyclic energy storage applications, featuring a pure lead construction and proprietary formulation, suitable for deep-cycle use scenarios.
In terms of capacity, the EVX12400 has a nominal voltage of 12 Vdc and a nominal capacity of 40 Ah (1.75 VPC @25°C, 20-hour rate). At 25°C, the 8-hour rate 1.75 VPC capacity is 31.52 Ah, the 20-hour rate 1.75 VPC capacity is 40.00 Ah, and the 8-hour rate 1.80 VPC capacity is 30.56 Ah. The maximum charge current is 12.00 A, the maximum discharge current is 400 A, the short-circuit current is 1082 A, and the internal resistance is 8.2 mΩ.
The battery uses a valve-regulated sealed lead-acid construction and absorbed glass mat technology, with a gas recombination efficiency of up to 99%, and is maintenance-free. The case material is ABS (UL 94-HB). The terminal is an I2 terminal that accepts an M6 bolt, with a terminal torque of 51.7±10.3 Kgf·cm, 44.9±9.0 Lbf·in, or 5.1±1.0 N·m. The dimensions are length 197.0±2.0 mm, width 165.0±2.0 mm, height 170.4±2.0 mm, and the weight is 13.20 kg.
In terms of cycle life, at 25°C it can reach 400 cycles at 100% depth of discharge and 1800 cycles at 30% depth of discharge. The nominal operating temperature is 25°C, the discharge temperature range is -15°C to 50°C, and the charge and storage temperature range is -15°C to 40°C. The equalizing charge voltage is 14.4 to 15.0 Vdc/battery (25°C). Regarding self-discharge, after 90 days of storage at 25°C the remaining capacity is greater than 90%, and it can be stored for up to 6 months; it must be fully charged before use, and if the storage temperature is above 25°C it should be charged sooner.
