Product details
CSB GP1272 belongs to the GP series of general purpose valve-regulated sealed lead-acid batteries, a product line covering 6V and 12V top-terminal VRLA-AGM types. The rated voltage is 12Vdc; at 25°C and 1.75VPC, the nominal capacity is 7.2Ah (20-hour rate), with 7.46Ah at the 8-hour rate and 8.24Ah at the 20-hour rate under the same conditions; at 25°C and 1.80VPC, the 8-hour rate is 7.37Ah. The battery uses a valve-regulated sealed construction with absorbed glass mat technology, achieving gas recombination efficiency of up to 99%, and employs pure lead construction and proprietary formulation elements, making it suitable for float standby power applications.
In terms of electrical parameters, the GP1272 has a maximum charge current of 2.16A, a maximum discharge current of 130, a short-circuit current of 276A, and an internal resistance of 23.0mΩ. The float voltage is 13.5 to 13.8Vdc (25°C), and the equalization voltage is 14.4 to 15.0Vdc (25°C). Self-discharge performance: after 90 days of storage at 25°C, the remaining capacity is still above 90%, and storage at 25°C is possible for up to 6 months; the battery must be fully charged before use, and if the storage temperature exceeds 25°C, charging is required earlier.
In terms of dimensions and terminals, the battery measures 150.9±2.0mm in length, 64.8±1.0mm in width, and 98.6±1.0mm in height, and weighs 2.40kg. The terminal type is F2 Faston Tab 250. The case material is ABS (UL 94-HB), and a flame-retardant (94-V0) version is also available upon request.
Regarding operating temperature, the nominal temperature is 25°C, the discharge temperature range is -15°C to 50°C, and the charge and storage temperature range is -15°C to 40°C. The design life can reach 5 years in float standby service at 25°C, 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).
The GP series is officially positioned as a general purpose VRLA battery series, applicable to a variety of scenarios including security, emergency lighting, and medical equipment. With its maintenance-free design, AGM technology, and float standby characteristics, the GP1272 is suitable for general applications requiring stable DC backup power.
