Product details
The CSB GP12260 belongs to the GP series of general-purpose valve-regulated sealed lead-acid batteries, featuring a 6V and 12V top-terminal VRLA-AGM construction, a nominal voltage of 12 Vdc, and a nominal capacity of 26 Ah (1.75 VPC @25°C, 20hr-rate). At 25°C, the 8-hour rate 1.75 VPC capacity is 27.1 Ah, the 20-hour rate 1.75 VPC capacity is 27.4 Ah, and the 8-hour rate 1.80 VPC capacity is 26.8 Ah, meeting the capacity consistency requirements of general-purpose standby power.
The battery uses a valve-regulated sealed lead-acid design and absorbed glass mat technology, with a gas recombination efficiency of up to 99%. It is a maintenance-free construction suitable for float standby power applications. Its maximum charge current is 7.80 A, maximum discharge current is 350 A, short-circuit current is 635 A, and internal resistance is 9.9 mΩ. The terminal is an I1 threaded lead alloy terminal that accepts an M5 bolt, with a terminal torque of 30.4±6.1 Kgf∙cm, 26.4±5.3 Lbf∙in, or 3.0±0.6 N∙m.
At 25°C, the float charge voltage of the GP12260 is 13.5 to 13.8 Vdc/battery, and the equalization charge voltage is 14.4 to 15.0 Vdc/battery. Its operating temperature range is: nominal 25°C, discharge -15°C to 50°C, charge and storage -15°C to 40°C. In terms of self-discharge, it is less than 10% after 90 days at 25°C and can be stored for up to 6 months; it must be fully charged before use, and if the storage temperature is above 25°C, it should be charged sooner.
In terms of dimensions, the battery length is 166.0±2.0 mm, width is 175.0±2.0 mm, height is 125.0±1.5 mm, and weight is 8.45 kg. The case material is ABS (UL 94-HB), and a flame-retardant 94-V0 version is available upon request. The design life is up to 5 years in 25°C float standby service, and 3 to 5 years per the Eurobat 20°C standard for commercial use. The product is manufactured in accordance with IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533).
Based on the above characteristics, the GP12260 is suitable for general-purpose float standby scenarios such as security systems, emergency lighting, and medical equipment, and can also be used in standby power applications requiring a 12V 26Ah class maintenance-free AGM battery. Its pure lead construction and proprietary formulation help maintain stable float performance, making it suitable for long-term standby use in controlled temperature environments.
