Product details
The CSB EVX12340 belongs to the EVX series and is a 12V valve-regulated sealed lead-acid battery featuring AGM technology that achieves up to 99% gas recombination efficiency, with pure lead construction. The series is positioned as a durable deep-cycle battery for electric mobility and cyclic energy storage applications, and the official application area of the EVX12340 is electric mobility.
In terms of capacity, the EVX12340 has a nominal capacity of 34Ah (1.75VPC @25°C, 20-hour rate); at 25°C, the 8-hour rate 1.75VPC capacity is 27.68Ah, the 20-hour rate 1.75VPC capacity is 34.40Ah, and the 8-hour rate 1.80VPC capacity is 27.28Ah. Its maximum charging current is 10.20A, maximum discharge current is 400A, short-circuit current is 849A, and internal resistance is 9.2mΩ. The equalizing charge voltage is 14.4 to 15.0Vdc/battery (25°C).
The battery dimensions are 195.6±2.0mm in length, 130.0±1.5mm in width, and 178.3±2.0mm in height, with a weight of 10.77kg (23.74 lb.). The terminals are B5 type, accepting M6 nuts and bolts, with a terminal torque of 51.7±10.3Kgf·cm, 44.9±9.0Lbf·in, or 5.1±1.0N·m. The case material is ABS, with a flame retardant rating of UL 94-HB.
Regarding operating temperatures, the nominal temperature is 25°C (77°F), the discharge temperature is -15°C to 50°C (5°F to 122°F), and the charge and storage temperature is -15°C to 40°C (5°F to 104°F). The design life is 400 cycles at 100% DOD at 25°C, or 1800 cycles at 30% DOD. In terms of 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; if the storage temperature is above 25°C, it should be charged sooner.
