Product details
The CSB GPL12650 is a 12V valve-regulated sealed lead-acid battery belonging to the GPL series. This series is the long life version of the GP series, intended for general-purpose float standby power applications and designed to provide a longer service life. The battery uses absorbed glass mat (AGM) technology, achieves gas recombination efficiency up to 99%, is a maintenance-free design, and uses pure lead construction with a proprietary formula. 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). Capacity data under different discharge conditions are: 63.60Ah at the 8-hour rate, 1.75VPC @25°C; 70.40Ah at the 20-hour rate, 1.75VPC @25°C; and 62.40Ah at the 8-hour rate, 1.80VPC @25°C. The battery's maximum charge current is 19.50A, maximum discharge current is 500A, short-circuit current is 1637A, and internal resistance is 5.3mΩ. These parameters provide a basis for charge and discharge management in standby power systems.
Structurally, the GPL12650 has dimensions of 349.4mm length, 166.0mm width, and 174.9mm height, with a weight of approximately 20.8kg. The terminal is an I2 threaded lead alloy terminal that accepts an M6 bolt, 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 can also be provided on request.
Regarding charging and temperature conditions, the float charge voltage at 25°C is 13.5 to 13.8 Vdc/cell, and the equalizing charge voltage is 14.4 to 15.0 Vdc/cell. The nominal operating temperature is 25°C; discharge can be performed from -15°C to 50°C, and charging and storage from -15°C to 40°C. For self-discharge, it is less than 10% after 90 days at 25°C, and it can be stored for up to 6 months; a full charge is required before use, and if the storage temperature is above 25°C, it should be charged sooner.
In terms of design life, the GPL12650 can reach up to 10 years in float standby service at 25°C, and more than 12 years under the Eurobat (20°C) standard, placing it in the Very Long Life class. This battery is suitable for float standby power applications such as general-purpose standby power systems, can operate stably under the above temperature and charging conditions, and provides a choice for standby power applications requiring long life and maintenance-free operation.
