Product details
The GP series includes a general purpose valve-regulated sealed lead-acid battery, model CSB GP12340, which is a 6V and 12V VRLA-AGM battery with top terminals. The battery has a nominal voltage of 12 Vdc; at 25°C and 1.75 VPC, its 20-hour rate nominal capacity reaches 34 Ah; under the same conditions, the 8-hour rate capacity is 34.7 Ah, the 20-hour rate capacity is 37.6 Ah, and the 8-hour rate capacity at 1.80 VPC is 34.1 Ah. This battery uses a valve-regulated sealed construction and absorbed glass mat technology, with a gas recombination efficiency of up to 99%. It is maintenance-free and uses a pure lead construction.
Electrically, the GP12340 can withstand a maximum charge current of 10.2 A, a maximum discharge current of 380 A, a short-circuit current of up to 915 A, and an internal resistance of 9.5 mΩ. At 25°C, the float charge voltage is between 13.5 and 13.8 Vdc/battery, and the equalization charge voltage is between 14.4 and 15.0 Vdc/battery. In terms of self-discharge, after 90 days of storage at 25°C, the remaining capacity still exceeds 90%, and it can be stored at 25°C for up to 6 months; however, it must be fully charged before use. If the storage temperature exceeds 25°C, a supplementary charge is required in advance.
In terms of dimensions and installation, the battery length is 195.6±2.0 mm, width is 130.0±1.5 mm, height is 178.3±2.0 mm, and weight is 10.48 kg. The terminal type is B5 terminal to accept M6 bolt, with terminal torque of 51.7±10.3 Kgf∙cm, 44.9±9.0 Lbf∙in, and 5.10±1.0 N∙m. The case material is ABS (UL 94-HB), and a flame-retardant (94-V0) version is available upon request.
Regarding operating temperature, the nominal temperature is 25°C, the discharge temperature range is from -15°C to 50°C, and the charge and storage temperature range is from -15°C to 40°C. Under 25°C float standby service, the design life can be up to 5 years; according to the Eurobat (20°C) standard, the commercial life is 3 to 5 years. The product is manufactured in accordance with IEC 61056-1/2:2012 and is UL1989 Recognized (MH14533) certified.
The GP series is positioned as a general purpose VRLA battery series, suitable for a variety of applications including security, emergency lighting, and medical equipment. The GP12340 is suitable for float standby power scenarios, and its capacity, terminal, and dimension parameters can provide reference for the above general purpose standby power designs.
