Product details
The GPL12880 model comes from CSB and is a 12V Valve Regulated Sealed Lead Acid battery in the GPL series general purpose product line. Compared with the GP series, this series has been treated for longer life in general purpose backup power applications. It uses Absorbent Glass Mat (AGM) technology with a gas recombination efficiency of up to 99%, combined with a pure lead construction and proprietary element design, making it suitable for float charge backup power. This 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 capacity at 1.75VPC is 88.00Ah, and the 8-hour rate capacity at 1.80VPC is 86.4Ah. The maximum charge current is 26.40A, the maximum discharge current is 800A, the short circuit current is 2098A, and the internal resistance is 3.6mΩ. Together, these data characterize the basic electrical performance of this model in backup and discharge states.
Charging and temperature conditions are also clearly specified. The float charge voltage at 25°C is 13.5 to 13.8Vdc, and the equalize charge voltage is 14.4 to 15.0Vdc. The nominal operating temperature is 25°C, the discharge temperature range is -15°C to 50°C, and the charge and storage temperature range is -15°C to 40°C. Regarding self-discharge characteristics, capacity loss after 90 days of storage at 25°C is less than 10%, and storage is possible for up to 6 months; the battery must be fully charged before use, and if the storage temperature exceeds 25°C, it must be charged earlier.
In terms of construction, the GPL12880 uses I2 threaded lead alloy terminals that accept M6 bolts, with a terminal torque of 51.7±10.3 Kgf·cm, 44.9±9.0 Lbf·in, or 5.10±1.0 N·m. The case material is PP (UL 94-HB), and a flame-retardant (94-V0) version is also available on request. The dimensions are 308.7±2.5mm long, 169.0±2.0mm wide, and 213.6±2.5mm high, with a weight of 29.70kg, or 65.46 lb.
In terms of design life, this model can reach 10 years in 25°C float charge backup service; according to the Eurobat (20°C) standard, it exceeds 12 years, placing it in the Very Long Life category. Overall, with its 12V 88Ah capacity specification, AGM valve regulated sealed construction, and long float charge design life, the GPL12880 is aimed at general purpose backup power and float charge service scenarios, suitable for industrial and infrastructure applications requiring stable DC backup power.
