Product details
The GP12650 in the CSB GP Series is a valve-regulated sealed lead-acid battery with a top terminal design, available in 6V and 12V specifications, belonging to the general purpose product line. Its nominal voltage is 12 Vdc; at 25°C and 1.75 VPC, the 20-hour rate rated capacity is 65 Ah; the 8-hour rate capacity is 62.9 Ah; and at the 8-hour rate and 1.80 VPC, it is 62.1 Ah. The battery uses Absorbent Glass Mat (AGM) technology, achieving up to 99% gas recombination efficiency, and features a maintenance-free design, making it suitable for float standby power applications.
Electrically, the GP12650 has a maximum charging current of 19.5 A, a maximum discharge current of 500 A, a short-circuit current of 1663 A, and an internal resistance of only 5.8 mΩ. At 25°C, the float charging voltage range is 13.5 to 13.8 Vdc, and the equalization charging voltage range is 14.4 to 15.0 Vdc. Regarding self-discharge, when stored at 25°C for 90 days, the self-discharge rate is less than 10%, and it can be stored for up to 6 months; a full charge is required before use, and if the storage temperature exceeds 25°C, the recharge interval should be shortened accordingly.
In terms of construction, the battery is equipped with I2 terminals compatible with M6 bolts, with terminal torque values of 51.7±10.3 Kgf∙cm, 44.9±9.0 Lbf∙in, or 5.10±1.0 N∙m. The case is made of PP material (UL 94-HB), and a flame-retardant 94-V0 version is available upon request. Dimensions are: length 349.4±2.5 mm, width 166.0±2.0 mm, height 174.9±2.0 mm, and weight 20.00 kg (44.08 lb).
Operating temperature range: nominal temperature 25°C; discharge from -15°C to 50°C; charging and storage from -15°C to 40°C. In terms of design life, it can reach 5 years in float standby service at 25°C; according to Eurobat 20°C standard commercial conditions, it is 3 to 5 years. The product is manufactured in accordance with IEC 60896-21/22:2004 and is UL1989 recognized (MH14533).
The GP Series is officially positioned as a general purpose VRLA battery series, widely serving various applications such as security, emergency lighting, and medical equipment. The GP12650 uses a pure lead construction and proprietary formulation, specifically designed for float standby power applications, serving as a backup power source in the aforementioned scenarios.
