Product details
The CSB GPL12260 is a 12V Top Terminal valve-regulated sealed lead-acid battery in the GPL series, utilizing AGM technology. The GPL series can be regarded as an extended-life version of the GP series, designed for general purpose standby power scenarios with the aim of extending service life in float mode. The battery uses a pure lead construction and a proprietary formulation, achieving a gas recombination efficiency of 99%. It is maintenance-free and suitable for float standby power applications.
In terms of capacity, the GPL12260 has a nominal capacity of 26 Ah (20-hour rate, 1.75 VPC, 25°C). At 25°C, the 8-hour rate capacity at 1.75 VPC is 26.72 Ah, the 20-hour rate capacity at 1.75 VPC is 29.00 Ah, and the 8-hour rate capacity 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 data can be used to evaluate its charge and discharge performance in standby power systems.
For charging parameters, at 25°C the float charge voltage is 13.5 to 13.8 Vdc/battery, and the equalize charge voltage is 14.4 to 15.0 Vdc/battery. In terms of operating temperature, the nominal 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. For self-discharge, storage at 25°C for 90 days results in less than 10% self-discharge, with a maximum storage of 6 months; a full charge is required before use. If the storage temperature exceeds 25°C, recharging is required earlier.
In terms of construction, the GPL12260 dimensions are length 166.0±2.0 mm, width 175.0±2.0 mm, and height 125.0±1.5 mm, with a weight of 8.30 kg. The terminals are I1 threaded lead alloy terminals, compatible with M5 bolts, with a terminal torque of 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in, or 3.0±0.6 N·m. The case material is ABS (UL 94-HB), and a flame-retardant (94-V0) version is also available upon request.
In terms of design life, float charging at 25°C can reach 8 years, and under the Eurobat (20°C) standard it is 10/12 years long life. The product is manufactured in accordance with IEC 61056-1/2:2012 and is recognized by UL1989 (MH14533). The GPL12260 is intended for general purpose float standby power scenarios and can provide stable standby power support for equipment under the above temperature and charging conditions.
