Product details
The CSB GPL12120 in the GPL series is a top-terminal 12V Valve Regulated Lead Acid (VRLA) battery featuring Absorbent Glass Mat (AGM) technology, with a gas recombination efficiency of up to 99%, and is maintenance-free. Nominal capacity 12 Ah (20-hour rate, 1.75 VPC @25°C); 8-hour rate capacity is 9.76 Ah (1.75 VPC @25°C) or 9.60 Ah (1.80 VPC @25°C). Dimensions: length 151.0±2.0 mm, width 98.0±1.0 mm, height 100.3±1.5 mm, weight approximately 4.10 kg, equipped with F2 Faston Tab 250 terminals.
Electrically, the GPL12120 has a maximum charge current of 3.60 A, maximum discharge current of 180 A, short-circuit current of 458 A, and internal resistance of 13.2 mΩ. Float charge voltage is 13.5 - 13.8 Vdc/cell (25°C), equalization charge voltage is 14.4 - 15.0 Vdc/cell (25°C). At 25°C, design float life is up to 8 years, meeting the Eurobat long life standard (10/12 years at 20°C). Self-discharge is low, with remaining capacity still above 90% after 90 days; can be stored for 6 months at 25°C, but must be fully charged before use; if storage temperature exceeds 25°C, charge in advance.
Operating temperature range: nominal 25°C, discharge -15°C to 50°C, charge/storage -15°C to 40°C. The case uses ABS (UL 94-HB) material, with a flame-retardant (94-V0) version also available on request. The product meets IEC 61056-1/2:2012 standards and is UL1989 certified (MH14533).
The GPL12120 is designed for float backup power applications and is the extended-life version of the GP series, widely used in general-purpose backup scenarios, including uninterruptible power supplies (UPS), emergency lighting, security systems, communication equipment, and various industrial backup power supplies. The pure lead construction and proprietary formulation help extend service life and ensure reliable power in backup service.
