Product details
The CSB RE1700 belongs to the RE series and is a 2V modular valve-regulated sealed lead-acid battery using VRLA-AGM and pure lead carbon technology, officially positioned as a high-capacity battery with excellent cycle life and long service life, for renewable energy applications. Its nominal voltage is 2 Vdc, and at 1.80 VPC, 25°C, 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) is 1264.00 Ah, and the 8-hour rate (1.80 VPC) 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, the maximum charge current is 119 (multi-stage) and 238 (CC-CV), recommended not to exceed 300. Recommended charging conditions include: for daily energy storage, CC-CV or multi-stage at 2.42±0.02 VDC/Unit (25°C) with current limit 0.07CA (84A); for power fluctuation control, CC-CV at 2.42±0.02 VDC/Unit (25°C) with current limit 0.14CA (168A).
Structurally, the RE1700 uses an I3 threaded copper alloy terminal, accepts an M10 bolt, and has a terminal torque of 249±50 Kgf∙cm, 216±43 Lbf∙in, or 24.4±4.9 N∙m. The case material is flame-retardant polypropylene (UL 94-V0). Dimensions are length 437.0±3.0 mm, width 172.0±3.0 mm, depth 497.0±3.0 mm, and weight 110.0 kg (242.5 lb).
For cycle life, at 25°C, 70%DOD reaches 2700 cycles, 50%DOD reaches 3800 cycles, and 30%DOD reaches 5900 cycles. Operating temperature range: nominal 25°C; discharge -25°C to 50°C; charge 0°C to 40°C; storage -20°C to 40°C. For self-discharge, at 25°C it is less than 10% after 90 days, can be stored for up to 6 months, requires a full charge before use, and should be charged sooner if storage temperature is above 25°C.
The battery is maintenance-free, AGM technology achieves up to 99% gas recombination efficiency, uses a pure lead structure and proprietary elements, is designed specifically for deep-cycle high-capacity applications, is manufactured in accordance with IEC 61427, and is recognized under UL1989 (MH14533). These features make it suitable for renewable energy storage and other applications requiring deep cycling and high capacity.
