Product details

The GP1245's construction combines a valve regulated sealed lead acid design with Absorbent Glass Mat technology, and achieves maintenance-free operation through gas recombination; the manufacturing process uses pure lead construction and proprietary elements, and production is carried out in accordance with IEC 61056-1/2:2012 and UL1989 recognition (MH14533). This model belongs to the CSB brand GP Series of general-purpose valve regulated sealed lead acid batteries, uses a VRLA-AGM construction, and has top terminals available in 6V and 12V versions. Its nominal voltage is 12 Vdc, and its nominal capacity at the 20-hour rate is 4.5Ah. It can serve applications such as security, emergency lighting, and medical equipment, and provides backup power through float charging. Capacity values are all at 25°C: 4.58 Ah at the 20-hour rate and 1.75 VPC; 4.23 Ah at the 8-hour rate and 1.80 VPC; 4.25 Ah at the 8-hour rate and 1.75 VPC. Maximum charge current is 1.35 A, maximum discharge current is 90, short-circuit current is 160 A, and internal resistance is 37.7 mΩ. The connection terminal is an F2 quick-connect tab 250, and the case material is ABS; UL 94-HB is standard, and a flame-retardant 94-V0 version is available on request. The overall battery dimensions are 92.8±1.0 mm long, 69.9±1.0 mm wide, and 107.7±1.5 mm high, with a weight of 1.66 kg. At 25°C, the float charge voltage is 13.5 to 13.8 Vdc, and the equalization charge voltage is 14.4 to 15.0 Vdc. For temperature range, nominal temperature is 25°C; discharge range is -15°C to 50°C; charge and storage range is -15°C to 40°C. When used in 25°C float standby service, design life can reach 5 years; under Eurobat 20°C standard commercial conditions, it is 3 to 5 years. For self-discharge, after 90 days at 25°C it is less than 10%, and the battery can be stored for up to 6 months; it must be fully charged before use, and if the storage temperature is above 25°C, it should be charged earlier.
