Product details
The CSB RE1700 is a 2V modular valve-regulated sealed lead-acid battery in the RE series. Combining VRLA-AGM and pure lead-carbon technology, it is positioned by the manufacturer as a high-capacity battery with excellent cycle life and long service life, primarily targeting renewable energy applications. Its nominal voltage is 2 Vdc. At 25°C and 1.80 VPC, the 100-hour rate nominal capacity is 1700 Ah; at the same temperature, the 20-hour rate (1.75 VPC) capacity is 1476.00 Ah, the 8-hour rate (1.75 VPC) capacity is 1264.00 Ah, and the 8-hour rate (1.80 VPC) capacity is 1248.00 Ah.
In terms of electrical performance, the battery's maximum discharge current is 9000 A, short-circuit current is 16743 A, and internal resistance is 0.36 mΩ. For charging parameters, the maximum charging current is 119 in multi-stage mode and 238 in CC-CV mode, with a recommended value not exceeding 300. Recommended charging conditions fall into two categories: for daily energy storage applications, use CC-CV or multi-stage charging at 2.42±0.02 VDC/Unit (25°C) with a current limit of 0.07CA (84A); for power fluctuation control, use CC-CV charging at 2.42±0.02 VDC/Unit (25°C) with a current limit of 0.14CA (168A).
In terms of structural design, the RE1700 features I3 threaded copper alloy terminals that accept M10 bolts, with a terminal torque of 249±50 Kgf∙cm, 216±43 Lbf∙in, or 24.4±4.9 N∙m. The case is made of flame-retardant polypropylene (UL 94-V0). Dimensions are 437.0±3.0 mm long, 172.0±3.0 mm wide, and 497.0±3.0 mm deep, with a weight of 110.0 kg (242.5 lb).
For cycle life at 25°C, the battery can deliver 2700 cycles at 70% DOD, 3800 cycles at 50% DOD, and 5900 cycles at 30% DOD. Operating temperature range: nominal 25°C; discharge -25°C to 50°C; charge 0°C to 40°C; storage -20°C to 40°C. Self-discharge characteristics: when stored at 25°C for 90 days, self-discharge is less than 10%; it can be stored for up to 6 months. It must be fully charged before use, and if storage temperature exceeds 25°C, it should be charged earlier.
The battery is maintenance-free. AGM technology enables gas recombination efficiency of up to 99%. It uses a pure lead structure and proprietary elements, and is purpose-built for deep-cycle high-capacity applications. It is manufactured in accordance with IEC 61427 and recognized under UL1989 (MH14533). These features make it suitable for scenarios requiring deep cycling and high capacity, such as renewable energy storage.
