Product details
CSB GP12400 is a general-purpose valve-regulated sealed lead-acid battery in the GP series, designed for float standby power. The GP series is officially positioned as a general-purpose VRLA battery series and can cover various applications such as security, emergency lighting, and medical equipment. Under standby service at 25°C, design life can reach 5 years; under Eurobat standard at 20°C, it is 3 to 5 years. The product is manufactured in accordance with IEC 61056-1/2:2012 and has obtained UL1989 recognition (MH14533).
Its construction is 6V and 12V top-terminal VRLA-AGM, with a nominal voltage of 12 Vdc; at 25°C and 1.75 VPC, the 20-hour rate nominal capacity is 40 Ah. When discharged at the 8-hour rate and 1.75 VPC, capacity is 43.6 Ah; at the 20-hour rate and 1.75 VPC, 48.0 Ah; at the 8-hour rate and 1.80 VPC, 43.0 Ah. Maximum charge current is 12.0 A, maximum discharge current is 400 A, short-circuit current is 1012 A, and internal resistance is 8.5 mΩ.
The battery relies on VRLA sealed construction and absorbent glass mat (AGM) technology, with gas recombination efficiency of up to 99%, and is maintenance-free during use. I2 threaded lead-alloy terminals can accept M6 bolts; torque specifications are 51.7±10.3 Kgf∙cm, 44.9±9.0 Lbf∙in, or 5.10±1.0 N∙m. The case is made of ABS (UL 94-HB); a flame-retardant 94-V0 version can also be supplied when required. Length 197.0±2.0 mm, width 165.0±2.0 mm, height 170.4±2.0 mm, weight approximately 12.92 kg.
At 25°C, float charge voltage is 13.5 to 13.8 Vdc/battery, and equalization charge voltage is 14.4 to 15.0 Vdc/battery. Nominal temperature is 25°C; discharge range is -15°C to 50°C, and charge and storage range is -15°C to 40°C. For self-discharge, after 90 days of storage at 25°C, remaining capacity is still greater than 90%; maximum storage is 6 months. It must be fully charged before use; if storage temperature exceeds 25°C, it should be recharged sooner.
Overall, the GP12400 combines 12V voltage, 40Ah nominal capacity, and an AGM maintenance-free construction, while providing clear float/equalization voltage ranges, a wide operating temperature range, and a standard terminal configuration, making it suitable as a general-purpose standby power source. Pure lead construction and a proprietary element formulation, together with a manufacturing basis according to relevant IEC and UL standards, provide a technical basis for reference in float standby applications.
