Product details
The CSB RE1200 is part of the RE series and is classified as a 2V VRLA-AGM modular valve-regulated sealed lead-acid battery, officially designated for renewable energy applications. This series utilizes a pure lead carbon high-capacity design and proprietary formulation, targeting deep cycle high-capacity requirements. Through its valve-regulated sealed construction and absorbent glass mat technology, gas recombination efficiency reaches up to 99%, and it requires no maintenance.
In terms of electrical specifications, the RE1200 operates at 2Vdc; at 1.80VPC and 25 degrees Celsius, the nominal capacity at the 100-hour rate is 1200Ah; at 1.75VPC, the 8-hour rate capacity is 824.00Ah, the 20-hour rate is 972.00Ah, and at 1.80VPC and the 8-hour rate it is 816.00Ah. The maximum discharge current can reach 6000A, the short-circuit current is 11400A, and the internal resistance is only 0.36 milliohms. The maximum charging current is 84A (multi-stage) or 168A (CC-CV), but must not exceed 200A.
Three charging methods are recommended: for daily energy storage, use CC-CV or multi-stage charging at 2.42±0.02 VDC/Unit, 25 degrees Celsius, with a current limit of 0.07CA (84A); for power fluctuation control, use CC-CV mode at 2.42±0.02 VDC/Unit, 25 degrees Celsius, with a current limit of 0.14CA (168A). Regarding self-discharge characteristics, when stored at 25 degrees Celsius for 90 days, self-discharge is less than 10%, and the battery can be stored for up to 6 months; it must be fully charged before use. If the storage temperature exceeds 25 degrees Celsius, recharge is required sooner.
In terms of construction, 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, compliant with 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 conditions: 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 2700 cycles at 70%DOD, 3800 cycles at 50%DOD, and 5900 cycles at 30%DOD. The product is manufactured in accordance with IEC 61427 and is UL1989 recognized (MH14533).
