Product details
The CSB RE1200 is part of the RE series and is a 2V VRLA-AGM modular Valve Regulated Sealed Lead Acid Battery, with renewable energy as its official application. The series combines a pure lead carbon high capacity design with a proprietary formulation, built for deep cycle high capacity scenarios. Thanks to its valve regulated sealed construction and Absorbent Glass Mat technology, it achieves 99% gas recombination efficiency and is a maintenance-free battery.
In terms of electrical parameters, the RE1200 has a voltage of 2Vdc. At 25 degrees Celsius and 1.80VPC, the nominal capacity at the 100-hour rate is 1200Ah; at 1.75VPC the 8-hour rate capacity is 824.00Ah, at 1.75VPC the 20-hour rate capacity is 972.00Ah, and at 1.80VPC the 8-hour rate capacity 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 in multi-stage mode and 168A in CC-CV mode, and must not exceed 200A.
There are three charging recommendations: for daily energy storage use CC-CV or multi-stage mode at 2.42±0.02 VDC/Unit, 25 degrees Celsius, with current limit 0.07CA (84A); for power fluctuation control use CC-CV mode at 2.42±0.02 VDC/Unit, 25 degrees Celsius, with current limit 0.14CA (168A). Regarding self-discharge, when stored at 25 degrees Celsius for 90 days, self-discharge is less than 10%, and storage can last up to 6 months; the battery must be fully charged before use, and if the storage temperature exceeds 25 degrees Celsius, it should be charged earlier.
Construction details: the RE1200 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 is made of flame retardant polypropylene and meets UL 94-V0. Dimensions are 303.0±3.0mm in length, 172.0±3.0mm in width, and 497.0±3.0mm in depth, with a weight of 73.8kg.
Temperature adaptability: nominal temperature 25 degrees Celsius, discharge range -25 to 50 degrees Celsius, charge range 0 to 40 degrees Celsius, storage range -20 to 40 degrees Celsius. Design life at 25 degrees Celsius is up to 2700 cycles at 70%DOD, 3800 cycles at 50%DOD, and 5900 cycles at 30%DOD. The product is manufactured to IEC 61427 and recognized under UL1989 (MH14533).
