Product details
The GPL12400 is a product in the CSB GPL series, which can be regarded as the long life version of the GP series, primarily designed for general purpose float backup power applications. This battery is a 12V valve regulated sealed lead acid type, utilizing AGM (Absorbent Glass Mat) technology with a gas recombination efficiency of up to 99%, and is maintenance-free. Its plates are made of pure lead, produced in accordance with IEC 61056-1/2:2012, and certified to UL1989 (MH14533).
In terms of capacity parameters, the GPL12400 has a nominal capacity of 40Ah at 25°C, 1.75 VPC, 20-hour rate. Also at 25°C, the 8-hour rate 1.75 VPC capacity is 40.32Ah, the 20-hour rate 1.75 VPC capacity is 44.40Ah, and the 8-hour rate 1.80 VPC capacity is 39.60Ah. The battery can withstand a maximum charge current of 12.00A, a maximum discharge current of 400A, a short circuit current of 1182A, and an internal resistance of 8.5 mΩ.
Dimensions and terminals: The GPL12400 has a length of 197.0±2.0 mm, a width of 165.0±2.0 mm, a height of 170.4±2.0 mm, and a weight of 12.92 kg. It is equipped with I2 threaded lead alloy terminals that can accommodate M6 bolts, with a terminal torque of 51.7±10.3 Kgf·cm, equivalent to 44.9±9.0 Lbf·in or 5.10±1.0 N·m. The case is made of ABS material (UL 94-HB), and a flame-retardant 94-V0 version is also available upon request.
Regarding charging and operating environment: At 25°C, the float charge voltage should be set to 13.5 to 13.8 Vdc/battery, and the equalization charge voltage should be 14.4 to 15.0 Vdc/battery. The nominal operating temperature is 25°C; the allowable discharge range is -15°C to 50°C; the charge and storage temperature range is -15°C to 40°C. In terms of self-discharge, the loss after 90 days of storage is less than 10%, and it can be stored for up to 6 months at 25°C, but must be fully charged before use; if the storage temperature exceeds 25°C, charging should be performed earlier.
Under 25°C float charge conditions, the GPL12400 has a design life of up to 10 years; according to the Eurobat 20°C standard, it belongs to the 10/12 year long life category. This battery is suitable for float backup power applications, and with its long life and maintenance-free features, it can meet the needs of general purpose backup power.
