Product details
EVX12200 is a 12V top-terminal valve-regulated sealed lead-acid battery in the CSB EVX series. It uses AGM technology, with gas recombination efficiency of up to 99%, and a pure lead construction for maintenance-free operation. This model is developed for electric mobility and deep-cycle energy applications, with a rated capacity of 20Ah (25°C, 1.75VPC, 20-hour rate); at an 8-hour rate, it is 16.96Ah (1.75VPC) or 16.24Ah (1.80VPC).
In terms of construction, the EVX12200 features I1 type terminals that can accept M5 bolts. Terminal torque options are 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in, or 3.0±0.6 N·m. The battery case uses ABS material and achieves a UL 94-HB flame retardant rating. Overall dimensions are length 181.0±2.0mm, width 76.0±1.0mm, and height 165.0±2.0mm; total weight is 6.55kg (14.44 lb).
Electrically, the battery has a maximum charge current of 6.00A, a maximum discharge current of 230A, a short-circuit current of 607A, and an internal resistance of 13.5mΩ. At 25°C, the equalization charge voltage is 14.4 to 15.0Vdc; float charge voltage is not provided in the available data. Self-discharge characteristics are: after 90 days at 25°C, self-discharge is less than 10%, and storage is possible for up to 6 months; it must be fully charged before reuse, and if storage temperature exceeds 25°C, it should be charged sooner.
Temperature and life: nominal temperature is 25°C. Discharge is permitted from -15°C to 50°C; charging and storage are permitted from -15°C to 40°C. At 25°C, cycle life is 400 cycles at 100% DOD and 1800 cycles at 30% DOD. The product is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008, and is UL1989 recognized (MH14533).
The EVX12200 can be used in electric mobility and deep-cycle scenarios. Its pure lead construction and AGM design support stable performance during cyclic use. During use, charge and discharge should be managed according to the voltage, current, and temperature conditions above; after storage, supplementary charging is also required as specified to keep the battery in normal operating condition.
