Product details
The CSB RE series includes the RE1200, a modular valve-regulated sealed lead-acid battery with a 2V VRLA-AGM design; the manufacturer's stated application direction is renewable energy. The series uses a pure lead-carbon high-capacity solution and a proprietary formulation to serve deep cycle, high-capacity requirements; its valve-regulated sealed construction combined with absorbed glass mat separators enables gas recombination efficiency of up to 99%, and it requires no maintenance during use.
Operating temperature and life: The nominal temperature is 25°C; discharge is permitted from -25 to 50°C, charge from 0 to 40°C, and storage from -20 to 40°C. In a 25°C environment, design cycle life 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).
Structural parameters: The I3 threaded copper alloy terminal can be fitted with an M10 bolt; tightening torques are 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 (L) × 172.0±3.0mm (W) × 497.0±3.0mm (D), and weight is 73.8kg.
Electrical performance: Rated voltage 2Vdc. When tested at 1.80VPC, 25°C, and the 100-hour rate, nominal capacity is 1200Ah; at 1.75VPC, the 8-hour rate is 824.00Ah and the 20-hour rate is 972.00Ah; at 1.80VPC, the 8-hour rate is 816.00Ah. Maximum discharge current is 6000A, short-circuit current is 11400A, and internal resistance is 0.36 milliohms. Charge current limits: 84A for multi-stage or 168A for CC-CV, and must not exceed 200A.
Charging and self-discharge: For daily energy storage, 2.42±0.02 VDC/Unit at 25°C with 0.07CA (84A) current limiting; CC-CV or multi-stage can be selected; for power fluctuation control, 2.42±0.02 VDC/Unit at 25°C with 0.14CA (168A) current limiting, using CC-CV. After 90 days at 25°C, self-discharge is less than 10%; maximum storage is 6 months, and it must be fully charged before use; if storage temperature is above 25°C, charge earlier.
