Product details
As a member of the GPL series, the CSB GPL1272 is a 12V top terminal valve regulated sealed lead acid battery officially positioned for general purpose use. It can be regarded as a long life upgraded version of the GP series, designed to deliver a longer service life for general purpose backup power applications. In terms of capacity, its nominal value is 7.2Ah (25°C, 1.75VPC, 20 hour rate); when discharged at the 8 hour rate, 1.75VPC, 25°C, the capacity is 6.80Ah; at the 20 hour rate, 1.75VPC, 25°C it is 7.32Ah; and at the 8 hour rate, 1.80VPC, 25°C it is 6.57Ah.
In terms of electrical parameters, the GPL1272 can withstand a maximum charge current of 2.16A, a maximum discharge current of 130A, a short circuit current of 265A, and an internal resistance of only 22.0mΩ. At 25°C, the float charge voltage range is 13.5 to 13.8Vdc, and the equalization charge voltage range is 14.4 to 15.0Vdc. Self-discharge performance: after 90 days of storage at 25°C, the remaining capacity is still above 90%; it can be stored at 25°C for up to 6 months, but must be fully charged before use; once the storage temperature exceeds 25°C, charging is required earlier.
Structurally, this battery utilizes a valve regulated sealed lead acid design and Absorbent Glass Mat (AGM) technology, with a gas recombination efficiency of up to 99%, achieving maintenance-free operation. The pure lead construction combined with proprietary formulation components, and the design specifically for float charge backup power applications, together form its core technical features. It is manufactured in accordance with IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533). The case is made of ABS (UL 94-HB) material; a flame retardant version (94-V0) is available upon request.
In terms of dimensions and weight, the GPL1272 measures 150.9±2.0mm in length, 64.8±1.0mm in width, and 98.6±1.0mm in height, and weighs 2.60kg (5.73 lb). The terminal is F2 Faston Tab 250. In terms of temperature adaptability, the nominal temperature is 25°C (77°F), discharge can be performed from -15°C to 50°C (5°F to 122°F), and charging and storage are permitted from -15°C to 40°C (5°F to 104°F).
In terms of life design, the GPL1272 can reach 8 years under float charge backup service at 25°C, and according to the Eurobat (20°C) standard it falls into the 10/12 year long life category. Considering capacity, dimensions, and float charge characteristics, this model is suitable for general purpose float charge backup power applications. It can complete discharge, charge, and storage at the nominal temperature of 25°C and within the specified temperature range, meeting the basic requirements of corresponding backup power systems for a 12V battery.
