Product details
The GP series of general purpose valve-regulated sealed lead-acid batteries includes the CSB GP12120, which is classified under the 6V and 12V top terminal VRLA-AGM types. The nominal voltage is 12 Vdc; at 25°C and 1.75 VPC, the nominal capacity is 12 Ah (20hr-rate); at the 8-hour rate, 1.75 VPC, and 25°C, the capacity is 11.2 Ah; at the 8-hour rate, 1.80 VPC, and 25°C, the capacity is 10.96 Ah; and at the 20-hour rate, 1.75 VPC, and 25°C, the capacity is 12.0 Ah.
In terms of electrical parameters, the GP12120 has a maximum charging current of 3.60 A, a maximum discharge current of 180 A, a short-circuit current of 378 A, and an internal resistance of 16.7 mΩ. The float charging voltage at 25°C is 13.5 to 13.8 Vdc/battery, and the equalization charging voltage at 25°C is 14.4 to 15.0 Vdc/battery. The terminal is an F2 terminal - Faston Tab 250 type. Regarding self-discharge characteristics, storage at 25°C for 90 days results in less than 10% self-discharge; at 25°C, storage is possible for up to 6 months, but the battery must be fully charged before use; if the storage temperature exceeds 25°C, charging is required sooner.
Dimensions and weight: The GP12120 is 151.0±2.0 mm long, 98.0±1.0 mm wide, 100.3±1.5 mm high, and weighs 3.67 kg. The case material is ABS (UL 94-HB), and a flame-retardant 94-V0 version is also available upon request. Operating temperature range: nominal temperature 25°C; discharge is permitted from -15°C to 50°C; charging and storage are permitted from -15°C to 40°C. In terms of design life, up to 5 years under float standby service at 25°C; according to the Eurobat (20°C) standard, the commercial life is 3 to 5 years.
This model uses a valve-regulated sealed lead-acid construction and absorbed glass mat AGM technology, with a gas recombination efficiency of up to 99%, is maintenance-free, and features a pure lead construction with proprietary elements. Manufacturing complies with IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533). The official application area is general purpose, suitable for float standby power scenarios such as security, emergency lighting, and medical equipment.
In practical use, the GP12120 is suitable for equipment and systems requiring 12V float standby power; users should set charging according to the float or equalization voltage requirements at 25°C and pay attention to storage temperature and recharge cycles to ensure the battery maintains normal operating condition.
