Product details
The CSB GPL1272 belongs to the GPL series and is a 12V top terminal valve-regulated lead-acid battery, officially positioned for general purpose use as the long-life version of the GP series, offering a longer service cycle for general standby power applications. Its nominal capacity is 7.2Ah (20-hour rate, 1.75VPC, 25°C), with a capacity of 6.80Ah at the 8-hour rate, 1.75VPC, 25°C, 7.32Ah at the 20-hour rate, 1.75VPC, 25°C, and 6.57Ah at the 8-hour rate, 1.80VPC, 25°C.
In terms of electrical characteristics, the GPL1272 has a maximum charge current of 2.16A, a maximum discharge current of 130A, a short-circuit current of 265A, and an internal resistance of 22.0mΩ. The float charge voltage is 13.5 to 13.8Vdc (25°C), and the equalizing charge voltage is 14.4 to 15.0Vdc (25°C). For self-discharge, more than 90% capacity remains after 90 days of storage at 25°C, and it can be stored at 25°C for up to 6 months, requiring a full charge before use; if the storage temperature is above 25°C, it should be charged sooner.
The battery uses a valve-regulated lead-acid structure and absorbed glass mat (AGM) technology, with a gas recombination efficiency of up to 99%, and is maintenance-free. Its pure lead construction and proprietary formulation components, combined with a design for float standby power applications, constitute the main technical features of the product. The product is manufactured in accordance with IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533). The case material is ABS (UL 94-HB), and a flame-retardant version (94-V0) is available upon request.
In terms of mechanical dimensions, the GPL1272 is 150.9±2.0mm long, 64.8±1.0mm wide, and 98.6±1.0mm high, with a weight of 2.60kg (5.73 lb). The terminal type is F2 Faston Tab 250. For operating temperature, the nominal temperature is 25°C (77°F), the discharge temperature range is -15°C to 50°C (5°F to 122°F), and the charge and storage temperature range is -15°C to 40°C (5°F to 104°F).
In terms of design life, the GPL1272 achieves up to 8 years under 25°C float standby service conditions, and 10/12 years long life under the Eurobat (20°C) standard. With the above capacity, dimensions, and float charge characteristics, this model is suitable for general purpose float standby power applications, and can be discharged, charged, and stored at the nominal temperature of 25°C and within the specified temperature range, meeting the basic 12V battery requirements of corresponding standby power systems.
