Product details
The CSB GPL12120 belongs to the GPL series and is a 12V top terminal valve-regulated sealed lead-acid (VRLA) battery using absorbed glass mat (AGM) technology, with gas recombination efficiency up to 99% and no maintenance required. Its nominal capacity is 12 Ah (20-hour rate, 1.75 VPC @25°C), with an 8-hour rate capacity of 9.76 Ah (1.75 VPC @25°C) or 9.60 Ah (1.80 VPC @25°C). Battery dimensions are length 151.0±2.0 mm, width 98.0±1.0 mm, height 100.3±1.5 mm, weight approximately 4.10 kg, with F2 Faston Tab 250 terminals.
In terms of electrical performance, 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), and equalizing charge voltage is 14.4 - 15.0 Vdc/cell (25°C). The battery has a design float life of up to 8 years at 25°C, meeting the Eurobat long-life standard (10/12 years at 20°C). Self-discharge is low, with remaining capacity over 90% after 90 days; it can be stored for up to 6 months at 25°C, but must be fully charged before use, and if storage temperature exceeds 25°C, it should be charged earlier.
The battery's operating temperature range: nominal 25°C, discharge -15°C to 50°C, charge/storage -15°C to 40°C. The case material is ABS (UL 94-HB), with a flame-retardant (94-V0) version available upon request. The product complies with IEC 61056-1/2:2012 and is certified to UL1989 (MH14533).
The GPL12120 is designed for float standby power applications and is the extended-life version of the GP series, suitable for general-purpose standby scenarios such as uninterruptible power supplies (UPS), emergency lighting, security systems, communication equipment, and various industrial standby power supplies. Its pure lead construction and proprietary formulation help extend service life, ensuring reliable power in standby service.
