Product details
The GPL12880, a 12V valve-regulated sealed lead-acid battery, belongs to CSB's GPL series and is positioned as a general-purpose product. This series was developed based on the GP series, with extended service life for general standby power applications. It utilizes Absorbent Glass Mat (AGM) technology, achieving a gas recombination efficiency of 99%, and features a pure lead construction with a proprietary element formulation, making it suitable for float standby power applications. The battery is maintenance-free, manufactured in accordance with IEC 60896-21/22:2004, and recognized under UL1989 (MH14533).
In terms of capacity parameters, at 25°C and 1.75VPC, the GPL12880 has a 20-hour rate nominal capacity of 88Ah and a 20-hour rate measured capacity of 94.80Ah; the 8-hour rate 1.75VPC capacity is 88.00Ah, and the 8-hour rate 1.80VPC capacity is 86.4Ah. The maximum charging current is 26.40A, the maximum discharge current is 800A, the short-circuit current is 2098A, and the internal resistance is 3.6mΩ. These values together outline the basic electrical characteristics of this model in standby and discharge states.
Charging and temperature conditions are also clearly specified. At 25°C, the float charging voltage ranges from 13.5 to 13.8Vdc, and the equalization charging voltage is 14.4 to 15.0Vdc. The nominal operating temperature is 25°C, the discharge temperature range is from -15°C to 50°C, and the charging and storage temperature range is -15°C to 40°C. Regarding self-discharge, when stored at 25°C for 90 days, capacity loss is less than 10%, and it can be stored for up to 6 months; it must be fully charged before use, and if the storage temperature exceeds 25°C, it requires charging in advance.
In terms of structural design, the GPL12880 is equipped with I2 threaded lead alloy terminals that accept M6 bolts, with terminal torque of 51.7±10.3 Kgf·cm, 44.9±9.0 Lbf·in, or 5.10±1.0 N·m. The case uses PP material (UL 94-HB), and a flame-retardant (94-V0) version can be provided upon request. The external dimensions are length 308.7±2.5mm, width 169.0±2.0mm, height 213.6±2.5mm, and weight 29.70kg (65.46 lb).
Regarding design life, this model can achieve 10 years in 25°C float standby service, and exceeds 12 years according to the Eurobat (20°C) standard, placing it in the Very Long Life category. Overall, with its 12V 88Ah capacity specification, AGM valve-regulated sealed construction, and long float design life, the GPL12880 is aimed at general-purpose standby power and float service scenarios, suitable for industrial and infrastructure applications requiring stable DC backup power.
