Product details
The GPL12260 is a product in CSB's GPL series, featuring AGM technology and a 12V Top Terminal. It is a Valve Regulated Sealed Lead Acid battery. Compared to the GP series, the GPL series offers a longer service life and is primarily designed for general-purpose backup power, allowing the battery to last longer under float charge. The battery uses a pure lead construction and a proprietary formula, achieving a gas recombination efficiency of up to 99%. It is maintenance-free and suitable for float-charge backup power.
In terms of capacity, the GPL12260 has a nominal capacity of 26 Ah (20-hour rate, 1.75 VPC, 25°C). Also at 25°C, the 8-hour rate at 1.75 VPC corresponds to 26.72 Ah, the 20-hour rate at 1.75 VPC corresponds to 29.00 Ah, and the 8-hour rate at 1.80 VPC is 26.00 Ah. The maximum charge current is 7.80 A, the maximum discharge current is 350 A, the short-circuit current is 662 A, and the internal resistance is 9.6 mΩ. These values help determine its charge and discharge performance in backup power systems.
Charging parameters: At 25°C, the float charge voltage range is 13.5 to 13.8 Vdc/battery, and the equalize charge voltage range is 14.4 to 15.0 Vdc/battery. Temperature conditions: nominal temperature 25°C; discharge allowed from -15°C to 50°C; charge and storage allowed from -15°C to 40°C. Self-discharge characteristics: when stored at 25°C for 90 days, self-discharge is less than 10%, and storage for up to 6 months is possible, but the battery must be fully charged before use; if the storage temperature exceeds 25°C, the recharge time should be advanced accordingly.
Dimensions and construction: The GPL12260 is 166.0±2.0 mm long, 175.0±2.0 mm wide, and 125.0±1.5 mm high, weighing 8.30 kg. The terminal uses an I1 threaded lead alloy, compatible with M5 bolts, with a torque of 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in, or 3.0±0.6 N·m. The case is made of ABS (UL 94-HB), and a flame-retardant (94-V0) version is also available upon request.
In terms of life, the design life under float charge at 25°C is 8 years; according to the Eurobat (20°C) standard, it falls into the 10/12-year long-life category. The product is manufactured in accordance with IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533). The GPL12260 primarily serves general-purpose float-charge backup power, providing reliable backup power continuously under the above temperature and charging conditions.
