Product details
The GPL12880 model is offered by CSB and belongs to the GPL series of general-purpose products; it is a 12V valve regulated sealed lead-acid battery. Compared with the GP series, the GPL series extends service life for general standby power applications; it uses an absorbent glass mat separator, i.e. AGM technology, with a maximum gas recombination efficiency of up to 99%. The pure lead construction plus proprietary element design make it suitable for float standby power. The battery is maintenance-free, is manufactured in accordance with IEC 60896-21/22:2004, and is recognized under UL1989 (MH14533).
Electrical data: at 25°C and 1.75VPC, the nominal capacity at the 20-hour rate is 88Ah, and the measured capacity is 94.80Ah; at the 8-hour rate, 1.75VPC corresponds to 88.00Ah, while 1.80VPC corresponds to 86.4Ah. The maximum charging current is 26.40A, and the maximum discharge current is 800A; short-circuit current is 2098A, and internal resistance is 3.6mΩ. These values indicate the basic electrical performance of this model in standby and discharge states.
Charging and temperature conditions are also clear. In a 25°C environment, float charge should be maintained at 13.5 to 13.8Vdc, and equalizing charge at 14.4 to 15.0Vdc. The nominal operating temperature is 25°C; discharge is allowed from -15°C to 50°C, and charging and storage are allowed from -15°C to 40°C. Self-discharge performance: when left unused at 25°C for 90 days, capacity loss is less than 10%, and storage can last up to 6 months; fully charge before use again, and if storage temperature exceeds 25°C, charge sooner.
The GPL12880 terminal is an I2 threaded lead alloy type and accepts M6 bolts; torque specifications include 51.7±10.3 Kgf·cm, 44.9±9.0 Lbf·in, and 5.10±1.0 N·m. The case is made of PP (UL 94-HB); a flame-retardant (94-V0) version is also available upon request. Length, width, and height are 308.7±2.5mm, 169.0±2.0mm, and 213.6±2.5mm respectively, and weight is 29.70kg (equivalent to 65.46 lb).
Service life data: under float standby service at 25°C, this model can reach 10 years; according to the Eurobat (20°C) standard, it exceeds 12 years and is classified as Very Long Life. In terms of overall positioning, the GPL12880 combines 12V 88Ah capacity, AGM valve regulated sealed construction, and a long float design life, targeting general standby power and float service, suitable for industrial and infrastructure scenarios that require stable DC backup power.
