Product details

The EVX12260 is part of CSB's EVX series and is a 12V top terminal valve-regulated sealed lead-acid (VRLA-AGM) battery. The series is officially positioned as a durable deep-cycle pure lead battery for electric mobility and cyclic energy storage applications. Its nominal capacity is 26Ah (1.75VPC @25°C, 20-hour rate); the 8-hour rate capacity is 23.28Ah, the 20-hour rate capacity is 26.60Ah, and the 8-hour rate 1.80VPC capacity is 22.48Ah. In terms of construction, the battery uses a pure lead construction with proprietary elements and absorbent glass mat (AGM) technology, with gas recombination efficiency of up to 99%, making it maintenance-free. Dimensions are: length 166.0±2.0mm, width 175.0±2.0mm, height 125.0±1.5mm, weight 8.65kg (19.06 lb). The case uses ABS (UL 94-HB) material, the terminal is an I1 threaded lead-alloy terminal that accepts M5 bolts, and the terminal torque is 30.4±6.1 Kgf·cm / 26.4±5.3 Lbf·in / 3.0±0.6 N·m. Electrically, the maximum charge current is 7.80A, the maximum discharge current is 350A, the short-circuit current is 797A, and the internal resistance is 9.6mΩ; the equalizing charge voltage is 14.4 to 15.0Vdc/battery (25°C). The self-discharge rate is below 10% after 90 days, and it can be stored for up to 6 months at 25°C; it must be fully charged before use. If the storage temperature is above 25°C, charge it earlier. Cycle life is as follows: 400 cycles at 25°C and 100% depth of discharge, or 1800 cycles at 25°C and 30% depth of discharge. Operating temperature range: nominal 25°C; discharge -15°C to 50°C; charge/storage -15°C to 40°C. The product meets IEC 60254-1:2005 / IEC 60254-2:2008 standards and is UL1989 recognized (MH14533). With its pure lead deep-cycle design and AGM technology, the EVX12260 can be used in electric mobility and deep-cycle applications, meeting cyclic use requirements and maintaining stable discharge performance within the specified temperature range.
