Product details

The GP1245 is a general purpose Valve Regulated Sealed Lead Acid battery in the CSB GP series, with a nominal voltage of 12 Vdc and a nominal capacity of 16W at the 15-minute rate (1.67 VPC @25°C). This battery utilizes Absorbent Glass Mat (AGM) technology, achieves a gas recombination efficiency of 99%, features a maintenance-free design, and is suitable for float charge backup power. In terms of electrical parameters, the GP1245 delivers 34.8 W/cell at the 5-minute rate (1.67 VPC @25°C) and 16.4 W/cell at the 15-minute rate. The maximum charge current is 1.60 A, the maximum discharge current is 90 A, the short-circuit current is 168 A, and the internal resistance is 29.8 mΩ. The float charge voltage should be maintained at 13.5 - 13.8 Vdc/battery (25°C), and the equalization charge voltage is 14.4 - 15.0 Vdc/battery (25°C). In terms of dimensions, the battery is 90.0±1.0 mm long, 70.0±1.0 mm wide, and 106.1±1.5 mm high, with a weight of approximately 1.34 kg. The terminal type is F2 terminal - Faston Tab 250. The case is made of ABS material (UL 94-HB), and a flame-retardant (94-V0) version is also available upon request. Operating temperature range: nominal 25°C; -15°C to 50°C during discharge; -15°C to 40°C during charge/storage. Under float charge conditions at 25°C, the design life can reach 5 years, meeting the Eurobat (20°C) 3-5 year standard commercial grade requirement. The self-discharge rate is low, less than 10% after 90 days, and it can be stored at 25°C for up to 6 months. It must be fully charged before use, and if the storage temperature exceeds 25°C, it should be charged earlier. This battery is manufactured in accordance with the IEC 61056-1/2:2012 standard and is recognized by UL1989 (MH14533). The official application area is general purpose, suitable for scenarios such as security, emergency lighting, and medical equipment.
