Product details

The CSB MSJ-200 belongs to the MSJ series of 2V valve-regulated sealed lead-acid batteries, using absorbed glass mat (AGM) technology with gas recombination efficiency of up to 99%, and is maintenance-free. Its nominal voltage is 2Vdc, with a 10-hour rate nominal capacity of 200Ah at 1.80VPC, 25°C; 8-hour rate (1.75VPC) capacity of 202.40Ah, 20-hour rate (1.75VPC) capacity of 210.00Ah, and 8-hour rate (1.80VPC) capacity of 197.60Ah. The battery uses pure lead construction and proprietary elements, suitable for high-capacity float standby power applications. The battery's design float charge voltage is 2.21 to 2.25Vdc/cell (25°C), and equalizing charge voltage is 2.35Vdc/cell (25°C). Maximum charge current is 60.00A, maximum discharge current is 1200A, short-circuit current is 3939A, and internal resistance is 0.42mΩ. Operating temperature range: nominal 25°C, discharge -15°C to 50°C, charge and storage -15°C to 40°C. Self-discharge rate is less than 10% after 90 days at 25°C, can be stored for up to 6 months, and requires full charge before use; if storage temperature is above 25°C, charge in advance. The MSJ-200 uses a flame-retardant ABS case (UL 94-V0), with I4 threaded copper alloy terminals that accept M8 bolts, and terminal torque of 126±25 Kgf·cm / 109±22 Lbf·in / 12.3±2.5 N·m. Dimensions are width 106.0±1.5mm, height 339.0±2.5mm, depth 170.0±2.0mm, and weight approximately 15.00kg (33.04 lb). The battery complies with IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533). The product's official application area is telecommunications, positioned as a 2V high-capacity, long-life standby power series, with a design life of up to 20 years under float service at 25°C, meeting the Eurobat long-life standard (greater than 12 years at 20°C). It is suitable for float standby power applications requiring high reliability and long backup time, such as DC power systems for telecom base stations and data centers.
