Product details
The CSB RE1700 in the RE Series is a 2V modular Valve Regulated Sealed Lead Acid Battery. It incorporates pure lead carbon technology and VRLA-AGM design, and is officially defined as a product with excellent cycle life, long service life, and high capacity, primarily used in renewable energy applications. At 25°C and 1.80 VPC, its 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. The nominal voltage is 2 Vdc.
In terms of electrical parameters, the battery has a short-circuit current of 16743 A, a maximum discharge current of 9000 A, and an internal resistance of 0.36 mΩ. For charging, the maximum charging current is 119 in multi-stage and 238 in CC-CV, with a recommended value not exceeding 300. For daily energy storage, CC-CV or multi-stage charging at 2.42±0.02 VDC/Unit (25°C) with a current limit of 0.07CA (84A) is recommended; for power fluctuation control, CC-CV charging at 2.42±0.02 VDC/Unit (25°C) with a current limit of 0.14CA (168A) is recommended.
In terms of construction, the RE1700 features I3 threaded copper alloy terminals, compatible with M10 bolts, with 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 437.0±3.0 mm in length, 172.0±3.0 mm in width, and 497.0±3.0 mm in depth, with a weight of 110.0 kg (242.5 lb).
For cycle life at 25°C, 30%DOD yields 5900 cycles, 50%DOD yields 3800 cycles, and 70%DOD yields 2700 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, storage at 25°C for 90 days results in less than 10% loss, and the battery can be stored for up to 6 months; it must be fully charged before use. If storage temperature exceeds 25°C, recharge is required earlier.
This battery is maintenance-free, with AGM technology achieving a gas recombination efficiency of up to 99%. Its pure lead construction and proprietary elements make it specifically designed for deep cycle high-capacity applications. It is manufactured in accordance with IEC 61427 and recognized under UL1989 (MH14533). Therefore, it is suitable for scenarios requiring deep cycling and high capacity, such as renewable energy storage.
