Product details

The CSB GP1245 belongs to the GP series of general-purpose valve-regulated sealed lead-acid batteries, with a nominal voltage of 12 Vdc and a nominal capacity of 16W @15Min-rate (1.67 VPC @25°C). The battery uses absorbed glass mat (AGM) technology with a gas recombination efficiency of up to 99%, is maintenance-free, and is suitable for float standby power applications. 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 charging 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 is 13.5 - 13.8 Vdc/battery (25°C), and the equalizing charge voltage is 14.4 - 15.0 Vdc/battery (25°C). The battery dimensions are 90.0±1.0 mm in length, 70.0±1.0 mm in width, and 106.1±1.5 mm in height, with a weight of approximately 1.34 kg. The terminal type is F2 terminal - Faston Tab 250. The case material is ABS (UL 94-HB), with a flame-retardant (94-V0) version available upon request. Operating temperature range: nominal 25°C; discharge -15°C to 50°C; charge/storage -15°C to 40°C. The design life is up to 5 years at 25°C float charge, meeting the Eurobat (20°C) 3-5 year standard commercial grade. The self-discharge rate is low, less than 10% after 90 days, and the battery 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. The battery is manufactured in accordance with IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533). Its official application area is general-purpose, suitable for scenarios such as security, emergency lighting, and medical equipment.
