Product details
The EVX12400 is part of the CSB EVX series. It is a 12V Top Terminal VRLA-AGM battery officially designated for electric mobility applications. This series targets electric mobility and cyclic energy storage scenarios, positioned as a durable deep cycle valve regulated sealed pure lead battery with a pure lead construction and proprietary formulation, capable of handling deep cycle use.
In terms of capacity, the battery 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, under 1.75 VPC, the 8-hour rate capacity is 31.52 Ah and the 20-hour rate capacity is 40.00 Ah; under 1.80 VPC, the 8-hour rate 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 adopts a valve regulated sealed lead acid construction and Absorbent Glass Mat technology, achieving a gas recombination efficiency of up to 99% and requiring no maintenance. The case material is ABS (UL 94-HB). It is equipped with an I2 terminal compatible with M6 bolts, with a terminal torque of 51.7±10.3 Kgf·cm, 44.9±9.0 Lbf·in, or 5.1±1.0 N·m. Dimensions are 197.0±2.0 mm in length, 165.0±2.0 mm in width, and 170.4±2.0 mm in height, with a weight of 13.20 kg.
For cycle life, at 25°C, it can deliver 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 equalization voltage is 14.4 to 15.0 Vdc/battery (25°C). In terms of self-discharge, after 90 days of storage at 25°C, the remaining capacity exceeds 90%, and the maximum storage period is 6 months; the battery must be fully charged before use. If the storage temperature is above 25°C, charge it in advance.
The product is manufactured to IEC 60254-1:2005 and IEC 60254-2:2008 standards and is UL1989 recognized (MH14533). Based on the above characteristics, this battery is suitable for electric mobility and cyclic energy storage applications.
