Product details
The CSB RE1200 belongs to the RE series. Its product type is a 2V VRLA-AGM modular valve-regulated sealed lead-acid battery, and its official application area is renewable energy. This series adopts a pure lead carbon high-capacity design and proprietary formulation, targeting deep-cycle high-capacity application scenarios. It uses a valve-regulated sealed structure and absorbed glass mat technology, with gas recombination efficiency of up to 99%, and is a maintenance-free battery.
In terms of electrical parameters, the RE1200 has a voltage of 2Vdc, a nominal capacity of 1200Ah at the 100-hour rate at 1.80VPC and 25 degrees Celsius; at the 8-hour rate at 1.75VPC the capacity is 824.00Ah, at the 20-hour rate at 1.75VPC it is 972.00Ah, and at the 8-hour rate at 1.80VPC it is 816.00Ah. The maximum discharge current is 6000A, the short-circuit current is 11400A, and the internal resistance is 0.36 milliohms. The maximum charge current is 84A (multi-stage) or 168A (CC-CV), and not exceeding 200A.
Recommended charging conditions fall into three categories: for daily energy storage, use CC-CV or multi-stage at 2.42±0.02 VDC/Unit, 25 degrees Celsius, with current limit 0.07CA (84A); for power fluctuation control, use CC-CV at 2.42±0.02 VDC/Unit, 25 degrees Celsius, with current limit 0.14CA (168A). Regarding self-discharge, at 25 degrees Celsius self-discharge is less than 10% after 90 days of storage, 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 degrees Celsius it should be charged sooner.
Structurally, the RE1200 uses an I3 threaded copper alloy terminal, accepts an M10 bolt, and the terminal torque is 249±50 Kgf∙cm, 216±43 Lbf∙in, or 24.4±4.9 N∙m. The case material is flame-retardant polypropylene, compliant with UL 94-V0. The dimensions are length 303.0±3.0mm, width 172.0±3.0mm, depth 497.0±3.0mm, and weight 73.8kg.
Regarding operating temperature, the nominal temperature is 25 degrees Celsius, the discharge range is -25 to 50 degrees Celsius, the charge range is 0 to 40 degrees Celsius, and the storage range is -20 to 40 degrees Celsius. The design life is 2700 cycles at 70%DOD, 3800 cycles at 50%DOD, and 5900 cycles at 30%DOD at 25 degrees Celsius. The product is manufactured in accordance with IEC 61427 and recognized under UL1989 (MH14533).
