Product details
Application-wise, the GP12260 addresses general-purpose float standby requirements for security systems, emergency lighting, medical equipment, etc., and can also serve as a standby power source for applications requiring maintenance-free AGM batteries in the 12V 26Ah class. In terms of product family, it belongs to the CSB GP series and is a general-purpose valve-regulated sealed lead-acid battery; its construction uses 6V and 12V top-terminal VRLA-AGM; rated voltage is 12 Vdc, nominal capacity is 26 Ah (1.75 VPC @25°C, 20hr-rate). At 25°C, calculated at the 8-hour rate/1.75 VPC, capacity is 27.1 Ah; at the 20-hour rate/1.75 VPC, capacity is 27.4 Ah; at the 8-hour rate/1.80 VPC, capacity is 26.8 Ah, meeting general-purpose standby power requirements for capacity consistency.
Length, width, and height are 166.0±2.0 mm, 175.0±2.0 mm, and 125.0±1.5 mm respectively; weight is 8.45 kg. ABS (UL 94-HB) is used as the case material, while the flame-retardant 94-V0 version is available on request.
Structurally, the battery combines valve-regulated sealed lead-acid design with absorbent glass mat technology, is maintenance-free, and achieves up to 99% gas recombination efficiency, making it suitable for float standby power. Current parameters are: maximum charge current 7.80 A, maximum discharge current 350 A, short-circuit current 635 A, and internal resistance 9.9 mΩ. Terminals use I1 threaded lead alloy and can be fitted with M5 bolts; torque values include 30.4±6.1 Kgf∙cm, 26.4±5.3 Lbf∙in, and 3.0±0.6 N∙m.
Charge settings and environmental limits are as follows: at 25°C, float voltage is 13.5 to 13.8 Vdc/battery, equalization voltage is 14.4 to 15.0 Vdc/battery; nominal temperature is 25°C, discharge temperature is -15°C to 50°C, and charge and storage temperature is -15°C to 40°C. For self-discharge, less than 10% after 90 days at 25°C, shelf life up to 6 months; fully charge before use; if storage temperature is above 25°C, charge earlier.
For life and compliance, design life can reach 5 years under 25°C float standby service; Eurobat 20°C standard commercial life is 3 to 5 years. Manufactured in accordance with IEC 61056-1/2:2012 and recognized to UL1989 (MH14533). With pure lead construction and proprietary formulation, float performance remains stable, making it suitable for long-term standby in controlled-temperature environments.
