Product details
For applications such as renewable energy that require deep cycling and high capacity, CSB has positioned the RE1700, a 2V modular valve-regulated sealed lead-acid battery, in its RE series. It uses VRLA-AGM and pure lead carbon technology, and is officially positioned as a battery with excellent cycle life, long service life, and high capacity. The RE1700 has a nominal voltage of 2 Vdc; at 25°C and 1.80 VPC, its nominal capacity at the 100-hour rate reaches 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.
For charging, a CC-CV or multi-stage method at 2.42±0.02 VDC/Unit (25°C) with a current limit of 0.07CA (84A) is recommended for daily energy storage; for power fluctuation control, a CC-CV method at 2.42±0.02 VDC/Unit (25°C) with a current limit of 0.14CA (168A) is recommended. The maximum charging current is 119 (multi-stage) and 238 (CC-CV), and it is recommended not to exceed 300. In terms of electrical performance, the maximum discharge current can reach 9000 A, the short-circuit current is 16743 A, and the internal resistance is 0.36 mΩ.
In the structural design, the case material is flame-retardant polypropylene (UL 94-V0); the dimensions are length 437.0±3.0 mm, width 172.0±3.0 mm, and depth 497.0±3.0 mm; the weight is 110.0 kg (242.5 lb). The terminals are I3 threaded copper alloy terminals that accept M10 bolts, and the terminal torque is 249±50 Kgf∙cm, 216±43 Lbf∙in, or 24.4±4.9 N∙m.
The operating temperature ranges include: nominal 25°C; discharge -25°C to 50°C; charge 0°C to 40°C; storage -20°C to 40°C. For cycle life, at 25°C, 70%DOD can complete 2700 cycles, 50%DOD can complete 3800 cycles, and 30%DOD can complete 5900 cycles. Self-discharge is less than 10% after 90 days at 25°C, and it can be stored for up to 6 months; it must be fully charged before use, and if the storage temperature is above 25°C, it should be charged earlier.
The battery is maintenance-free, and AGM technology allows gas recombination efficiency of up to 99%; the pure lead structure and use of proprietary elements make it specially designed for deep-cycle, high-capacity scenarios. The product is manufactured according to IEC 61427 and is recognized under UL1989 (MH14533). With these features, it is suitable for renewable energy storage and other applications that require deep cycling and high capacity.
