Product details
The CSB GP1272F2 belongs to the GP Series of general-purpose valve-regulated sealed lead-acid batteries, using absorbed glass mat (AGM) technology with gas recombination efficiency up to 99% and a maintenance-free design. Its nominal voltage is 12 Vdc; at 1.67 VPC @25°C, the 15-minute rate power is 28W, the 5-minute rate power is 56.5 W/cell, and the 15-minute rate power is 28.6 W/cell. Battery dimensions are 150.90 mm length, 64.80 mm width, and 98.60 mm height, weight approximately 2.10 kg, equipped with F2 terminals (Faston Tab 250).
This battery is suitable for float standby power applications such as security systems, emergency lighting, and medical equipment. Its float charge voltage is 13.5 - 13.8 Vdc/battery (25°C), and equalizing charge voltage is 14.4 - 15.0 Vdc/battery (25°C). Maximum charge current is 2.80 A, maximum discharge current is 130 A, short-circuit current is 304 A, and internal resistance is 19.8 mΩ. Operating temperature range: discharge -15°C to 50°C, charge/storage -15°C to 40°C, nominal operating temperature 25°C.
At 25°C, the battery self-discharge rate is below 10% (after 90 days), can be stored for up to 6 months, and requires a full charge before use; if storage temperature exceeds 25°C, charge in advance. Design life can reach 5 years under 25°C float conditions, meeting the Eurobat standard (20°C) 3-5 year commercial-grade life. The case material is ABS (UL 94-HB); a flame-retardant version (94-V0) is available upon request.
The product is manufactured according to IEC 61056-1/2:2012 and certified to UL1989 (MH14533). It uses a pure lead construction and proprietary formulation to ensure stable performance. Suitable for general-purpose applications requiring reliable standby power, but not for high-rate discharge or deep-cycle scenarios. During installation, ensure good ventilation and avoid short circuits and reverse connection.
