Product details
CSB EVH12240 in the EVH series is classified as 12V Top Terminal VRLA-AGM, and also belongs to the 12V valve-regulated sealed lead-acid battery category. The EVH series, intended for electric mobility applications, is officially regarded as an upgraded version of the EVX series, with improvements in cycle life and cycle durability. Its design incorporates absorbed glass mat (AGM) separator technology, with gas recombination efficiency up to 99%; the construction uses pure lead and proprietary formulation elements, and the battery is maintenance-free overall.
At 25°C, 20-hour rate, and 1.75 VPC, the nominal capacity of the EVH12240 is 24 Ah. Also at 25°C, the 8-hour rate at 1.75 VPC corresponds to 24.72 Ah, the 20-hour rate at 1.75 VPC corresponds to 25.60 Ah, and the 8-hour rate at 1.80 VPC corresponds to 24.48 Ah. The maximum charging current is 7.20 A, the maximum discharge current is 320 A, the short-circuit current is 848 A, and the measured internal resistance is 8.6 mΩ. At 25°C, the equalization voltage range is 14.4 to 15.0 Vdc/battery.
Mechanically, length is 181.0±2.0 mm, width is 76.2±1.0 mm, height is 170.0±2.0 mm, and weight is 7.55 kg. The terminal is I1 terminal to accept M5 bolt; tightening torque may refer to 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in, or 3.0±0.6 N·m. The case material is ABS, and the flame retardant rating reaches UL 94-HB.
Cycle durability: at 25°C, the design cycle count at 100% DOD is 350 cycles, and at 30% DOD it is 1800 cycles. Temperature conditions are: nominal temperature 25°C; discharge allowed from -15°C to 50°C; charge and storage allowed from -15°C to 40°C. Self-discharge performance: after 90 days at 25°C, self-discharge is less than 10%; maximum storage is 6 months. Recharge fully before reuse; if storage temperature exceeds 25°C, recharge earlier.
