Product details
The CSB GPL12650 is part of the GPL series and is a 12V valve-regulated sealed lead-acid battery that can be regarded as the long life version of the GP series, designed specifically for general-purpose float standby power with the goal of extending service life. It uses absorbed glass mat (AGM) technology, achieves up to 99% gas recombination efficiency, is maintenance-free, and features a pure lead construction and proprietary formulation. The product is manufactured in accordance with IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533).
In terms of capacity, the GPL12650 has a nominal capacity of 65Ah (1.75VPC @25°C, 20-hour rate). Capacities under various discharge conditions are as follows: 63.60Ah at the 8-hour rate at 1.75VPC @25°C; 70.40Ah at the 20-hour rate at 1.75VPC @25°C; 62.40Ah at the 8-hour rate at 1.80VPC @25°C. The battery has a maximum charge current of 19.50A, a maximum discharge current of 500A, a short-circuit current of 1637A, and an internal resistance of 5.3mΩ. Such parameters can serve as a reference for charge and discharge management of standby power systems.
In terms of dimensions, the GPL12650 is 349.4mm long, 166.0mm wide, and 174.9mm high, weighing approximately 20.8kg. The terminals are I2 threaded lead alloy terminals suitable for M6 bolts, with a terminal torque of 51.7±10.3 Kgf·cm (i.e., 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 available upon request.
Charging and temperature conditions: at 25°C, the float charge voltage is 13.5 to 13.8 Vdc per cell, and the equalization charge voltage is 14.4 to 15.0 Vdc per cell. The nominal operating temperature is 25°C; discharge can be performed from -15°C to 50°C, while charging and storage are from -15°C to 40°C. Regarding self-discharge, storage at 25°C for 90 days 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 should be charged earlier.
In terms of design life, the GPL12650 has a maximum of 10 years under float standby service at 25°C and exceeds 12 years under the Eurobat (20°C) standard, placing it in the Very Long Life category. This battery is suitable for float standby power applications, such as general-purpose standby power systems, and can operate stably under the above temperature and charging conditions, providing a choice for standby power scenarios requiring long life and maintenance-free operation.
