Product details
The CSB EVX12120 is a member of the EVX family, a 12V top terminal Valve Regulated Sealed Lead Acid battery. It utilizes Absorbent Glass Mat (AGM) technology with a gas recombination efficiency of up to 99%, and features a pure lead construction and proprietary formula. This series is positioned as a durable deep cycle VRLA pure lead battery series for electric mobility and cyclic energy storage applications, so this battery can adapt to usage scenarios requiring repeated charge and discharge.
In terms of capacity, at 25°C and 1.75VPC, the EVX12120 has a 20-hour rate nominal capacity of 12Ah, an 8-hour rate capacity of 10.64Ah, and 10.56Ah at the 8-hour rate under 1.80VPC conditions. The battery's maximum charging current is 3.60A, equalization voltage is 14.4 to 15.0Vdc (25°C), internal resistance is 15.4mΩ, and short-circuit current is 464A. These parameters can be referenced when matching charging equipment with the system.
In terms of construction, the battery dimensions are length 151.0±2.0mm, width 98.0±1.0mm, height 100.3±1.5mm, and weight approximately 3.83kg. The case is made of ABS material with a flame retardant rating of UL 94-HB, and the terminal is F2 Faston Tab 250. The battery is maintenance-free, with a nominal normal operating temperature of 25°C, a discharge temperature range of -15°C to 50°C, and a charge and storage temperature range of -15°C to 40°C.
In terms of cycle life, at 25°C, 100% depth of discharge can reach 400 cycles, and 30% depth of discharge can reach 1800 cycles. Regarding self-discharge, after 90 days of storage at 25°C, capacity loss is less than 10%, 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, supplementary charging should be done earlier. The product is manufactured according to IEC 60254-1:2005 and IEC 60254-2:2008, and is UL1989 recognized (MH14533).
Overall, the EVX12120 combines 12V voltage, 12Ah capacity, and deep cycle characteristics, making it suitable for electric mobility and energy applications requiring cyclic charge and discharge. Its valve regulated sealed and AGM construction supports maintenance-free use, and the pure lead construction and proprietary elements help meet durability requirements under cyclic conditions.
