Product details
The EVX12400 is part of the EVX series and is classified as a 12V Top Terminal VRLA-AGM battery, officially designated for electric mobility. This series is engineered for electric mobility and cyclic energy storage, featuring a durable deep cycle VRLA pure lead design with pure lead construction and a proprietary formulation to meet deep cycling demands.
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 capacity at 1.75 VPC is 31.52 Ah, the 20-hour rate capacity at 1.75 VPC is 40.00 Ah, and the 8-hour rate capacity at 1.80 VPC 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 only 8.2 mΩ.
This battery combines VRLA construction with absorbed glass mat technology, achieving a gas recombination efficiency of up to 99% and is maintenance-free. The case is made of ABS (UL 94-HB). The terminal specification is I2, compatible with M6 bolts, with torque values 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, 100% depth of discharge yields 400 cycles, and 30% depth of discharge yields 1800 cycles. 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). Self-discharge performance: after 90 days of storage at 25°C, the remaining capacity exceeds 90%, with a maximum storage of 6 months; a full charge is required before use. If the storage temperature exceeds 25°C, recharge should be performed earlier.
This product is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008 standards and is UL1989 recognized (MH14533). With these features, it is well-suited for electric mobility and cyclic energy storage applications.
