Product details

In CSB's MSJ product series, the MSJ-1000 is a valve-regulated sealed lead-acid battery using a 2V VRLA-AGM design. It is officially positioned as a series for telecom backup, featuring high capacity and longer life. When in float standby service at 25°C, the design life is up to 20 years; when measured by the Eurobat 20°C standard, it reaches the >12-year ultra-long-life category. It is manufactured with a pure lead construction and proprietary formulation elements; absorbent glass mat (AGM) technology enables gas recombination efficiency of up to 99% while maintaining a maintenance-free design. Dimensions: width 171.0±2.0mm, height 339.0±2.5mm, depth 471.0±2.5mm, weight 72.80kg. The case is made of flame-retardant ABS and meets UL 94-V0; the terminals use I4 threaded copper alloy and can accept M8 bolts, with torque 126±25 Kgf·cm, 109±22 Lbf·in, or 12.3±2.5 N·m. Electrical and capacity: rated voltage 2Vdc, internal resistance 0.28 mΩ; maximum charge current 300.00A, maximum discharge current 6000A. The nominal capacity of 1000Ah corresponds to 1.80VPC, 25°C, 10-hour rate. At other rates, the 8-hour rate at 1.75VPC is 1016.00Ah, the 20-hour rate at 1.75VPC is 1050.00Ah; the 8-hour rate at 1.80VPC is 984.00Ah. At 25°C, float charge should be maintained at 2.21 to 2.25Vdc, and equalizing charge at 2.35Vdc. Nominal operating temperature is 25°C; discharge allows -15°C to 50°C, while charge and storage allow -15°C to 40°C. Regarding self-discharge, after 90 days storage at 25°C, capacity loss is less than 10%; it can be stored for up to 6 months, and must be fully charged before use. If storage temperature exceeds 25°C, supplementary charging should be done sooner. Manufacturing is based on IEC 60896-21/22:2004, and it has obtained UL1989 recognition (MH14533). It is positioned as a high-capacity float standby power supply; the official application direction is telecommunications, and it can serve as backup power for communication systems.
