Product details
The CSB EVX12120 belongs to the EVX series and is a 12V top terminal valve-regulated sealed lead-acid battery that uses absorbed glass mat (AGM) technology to achieve up to 99% gas recombination efficiency, along with a pure lead construction and proprietary formulation. This series is positioned as a durable deep-cycle VRLA pure lead battery series for electric mobility and cyclic energy storage applications, making this battery suitable for usage patterns requiring repeated charge and discharge.
In terms of capacity, the EVX12120 has a nominal capacity of 12Ah at the 20-hour rate at 25°C and 1.75VPC, 10.64Ah at the 8-hour rate, and 10.56Ah at the 8-hour rate at 1.80VPC. The battery's maximum charge current is 3.60A, equalizing charge voltage is 14.4 to 15.0Vdc (25°C), internal resistance is 15.4mΩ, and short-circuit current is 464A. These parameters provide a basis for matching charging equipment and systems.
Structurally, the battery's dimensions are 151.0±2.0mm in length, 98.0±1.0mm in width, and 100.3±1.5mm in height, with a weight of approximately 3.83kg. The case material is ABS with a flame retardant rating of UL 94-HB, and the terminal is F2 Faston Tab 250. The battery features a maintenance-free design, 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 it can reach 400 cycles at 100% depth of discharge and 1800 cycles at 30% depth of discharge. Regarding self-discharge, capacity loss is less than 10% after 90 days of storage at 25°C, and it can be stored for up to 6 months, requiring a full charge before use; if storage temperature is above 25°C, recharge should be performed sooner. The product is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008, and is recognized under UL1989 (MH14533).
Overall, the EVX12120 combines 12V voltage, 12Ah capacity, and deep-cycle characteristics, making it suitable for electric mobility and energy application scenarios requiring cyclic charge and discharge. Its valve-regulated sealed and AGM construction supports maintenance-free use, while the pure lead construction and proprietary elements help meet durability requirements under cyclic operating conditions.
