Product details

The CSB GP1272 is a general purpose Valve Regulated Sealed Lead Acid battery in the GP series, belonging to the 6V and 12V top terminal VRLA-AGM product type. Rated voltage is 12Vdc, nominal capacity is 7.2Ah at 25°C, 1.75VPC (20-hour rate); also at 25°C, 1.75VPC, the 8-hour rate is 7.46Ah, the 20-hour rate is 8.24Ah, while at 25°C, 1.80VPC the 8-hour rate is 7.37Ah. This battery utilizes a valve regulated sealed construction and Absorbent Glass Mat technology, with gas recombination efficiency up to 99%, and features a pure lead construction with proprietary formulation elements, suitable for float backup power applications. In terms of electrical parameters, the GP1272 has a maximum charge current of 2.16A, maximum discharge current of 130, short circuit current of 276A, and internal resistance of 23.0mΩ. Float charge voltage is 13.5 to 13.8Vdc (25°C), equalization charge voltage is 14.4 to 15.0Vdc (25°C). Self-discharge performance: after 90 days storage at 25°C, remaining capacity is still above 90%, and it can be stored for up to 6 months at 25°C; it must be fully charged before use, and if storage temperature exceeds 25°C, a refresh charge is required. Dimensions and terminals: battery length 150.9±2.0mm, width 64.8±1.0mm, height 98.6±1.0mm, weight 2.40kg. Terminal type is F2 Faston Tab 250. The case is made of ABS (UL 94-HB), and a flame retardant (94-V0) version is available upon request. Operating temperature: nominal temperature 25°C, discharge temperature range -15°C to 50°C, charge and storage temperature range -15°C to 40°C. Design life is up to 5 years in float standby service at 25°C, and 3 to 5 years for Eurobat (20°C) standard 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, suitable for a variety of applications such as security, emergency lighting, and medical equipment. With its maintenance-free design, AGM technology, and float standby characteristics, the GP1272 is suitable for general scenarios requiring stable DC backup power.
