Product details

The MSJ-200 belongs to the MSJ series. It is a 2V valve-regulated sealed lead-acid battery with a maintenance-free design. Its official application is telecommunications, making it suitable for high-capacity float backup power applications, such as DC power systems for infrastructure including telecom base stations and data centers. The battery uses absorbent glass mat (AGM) technology, with gas recombination efficiency of up to 99%. Under 25°C float charging conditions, the design life can reach 20 years, and it meets the Eurobat long-life standard (greater than 12 years at 20°C). Nominal voltage is 2Vdc; at 25°C and 1.80VPC, the nominal capacity at the 10-hour rate is 200Ah. At the 8-hour rate at 1.75VPC, capacity is 202.40Ah; at the 20-hour rate at 1.75VPC, capacity is 210.00Ah; at the 8-hour rate at 1.80VPC, capacity is 197.60Ah. The battery is constructed of pure lead with proprietary elements. At 25°C, the design float voltage is 2.21 to 2.25Vdc/cell, and the equalization voltage is 2.35Vdc/cell; maximum charge current is 60.00A, maximum discharge current is 1200A, short-circuit current is 3939A, and internal resistance is 0.42mΩ. For temperature, nominal is 25°C, the discharge range is -15°C to 50°C, and the charge and storage range is -15°C to 40°C. Self-discharge is less than 10% over 90 days at 25°C; it can be stored for 6 months and must be fully charged before being put into service. If storage temperature exceeds 25°C, charge it earlier. The case uses flame-retardant ABS (UL 94-V0); terminals are I4 threaded copper alloy terminals that accept M8 bolts, with torque 126±25 Kgf·cm / 109±22 Lbf·in / 12.3±2.5 N·m. Dimensions: width 106.0±1.5mm, height 339.0±2.5mm, depth 170.0±2.0mm; weight approximately 15.00kg (33.04 lb). This product complies with IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533).
