Product details
The EVX1272 is a 12V valve-regulated sealed lead-acid battery in the CSB EVX product line, with terminals located on top. Its separator uses AGM absorbent glass mat technology, and gas recombination efficiency can reach up to 99%; it also uses pure lead construction and a proprietary formulation. This series is aimed at electric mobility and cyclic energy storage, pursuing durable deep-cycle pure lead performance; for the EVX1272, the official application direction is electric mobility.
For capacity data, at 25°C, 1.75VPC, and 20-hour rate, the nominal capacity is 7.2Ah. The data also lists: 6.00Ah at 25°C, 1.75VPC, 8-hour rate; 7.20Ah at 25°C, 1.75VPC, 20-hour rate; 5.76Ah at 25°C, 1.80VPC, 8-hour rate. Maximum charge current is 2.16A; maximum discharge current is 130; short-circuit current is 292A; internal resistance is 23.9mΩ.
Dimensions and construction: length 150.9±2.0mm, width 64.8±1.0mm, height 98.6±1.0mm, weight 2.55kg, terminal is F2 Faston Tab 250. Case material is ABS, flame retardant rating UL 94-HB. Equalization charge voltage at 25°C is 14.4 to 15.0Vdc; float charge voltage data is not provided. Temperature conditions: nominal 25°C; discharge can be at -15°C to 50°C; charging and storage can be at -15°C to 40°C.
Cycle life and self-discharge: at 25°C and 100% depth of discharge, cycle count can reach 400; at 30% depth of discharge, cycle count can reach 1800. Stored at 25°C for 90 days, capacity loss is less than 10%, and the storage limit is 6 months; fully charge before reuse, and if the storage temperature exceeds 25°C, supplementary charging should be earlier. Manufacturing standards include IEC 60254-1:2005 and IEC 60254-2:2008, and it has obtained UL1989 recognition (MH14533).
Therefore, the EVX1272 is suitable for electric mobility and deep cycle applications. The maintenance-free design and AGM gas recombination technology can reduce routine maintenance frequency. When selecting a model, actual discharge rate, ambient temperature, and cycle depth should be taken into consideration, and capacity and life data in the documentation should be referenced for judgment.
