Product details
The CSB GPL1272 is a GPL series product; it is a 12V valve-regulated sealed lead-acid battery with top terminals. It is positioned for general-purpose use and serves as the long-life version of the GP series, delivering a longer service life in general standby power applications.
Dimensions: length 150.9±2.0mm, width 64.8±1.0mm, height 98.6±1.0mm, weight 2.60kg (5.73 lb). Terminal specification: F2 Faston Tab 250. Temperature conditions: nominal 25°C (77°F); discharge can be from -15°C to 50°C (5°F to 122°F); charging and storage can be from -15°C to 40°C (5°F to 104°F).
Capacity: the rated value is 7.2Ah at the 20-hour rate, 1.75VPC, 25°C; also at the 20-hour rate, 1.75VPC, 25°C, there is an additional 7.32Ah figure. At the 8-hour rate, 1.75VPC, 25°C, it is 6.80Ah; at the 8-hour rate, 1.80VPC, 25°C, it is 6.57Ah.
Electrical performance: maximum charge current 2.16A, maximum discharge current 130A, short-circuit current 265A, internal resistance 22.0mΩ. At 25°C, float voltage 13.5 to 13.8Vdc, equalization voltage 14.4 to 15.0Vdc. For self-discharge, capacity remains above 90% after 90 days at 25°C; it can be stored for up to 6 months at 25°C and must be fully charged before use; if the temperature is above 25°C, charge it earlier.
The battery combines a valve-regulated sealed lead-acid construction with Absorbent Glass Mat (AGM) technology, achieves up to 99% gas recombination efficiency, and is maintenance-free. Its pure lead construction and proprietary formulation components, together with a design for float standby power applications, form its main technical features. Production follows IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533). The case uses ABS (UL 94-HB), with a flame-retardant version (94-V0) optional.
In terms of life, the design life is 8 years for float standby service at 25°C; under the Eurobat (20°C) standard, it has a 10/12-year long life. Based on the above capacity, dimensions, and float performance, this model can be used for general-purpose float standby power and can discharge, charge, and be stored at the nominal 25°C and within the specified temperature range, meeting the basic 12V battery requirements of corresponding standby power systems.
