Product details

The CSB battery MSJ-1000 is a 2V VRLA-AGM Valve Regulated Sealed Lead Acid battery in the MSJ series, officially defined as a high-capacity, long-life battery series for telecom backup applications. In float standby at 25°C, its design life is up to 20 years; according to the Eurobat 20°C standard, this product falls into the greater than 12-year ultra-long-life classification. The battery uses Absorbent Glass Mat AGM technology with 99% gas recombination efficiency, a maintenance-free design, and a pure lead construction with proprietary formulation elements. In terms of capacity, the MSJ-1000 has a nominal capacity of 1000Ah based on testing at 1.80VPC, 25°C, and the 10-hour rate. Other capacity data are: 1016.00Ah at the 8-hour rate and 1.75VPC, 1050.00Ah at the 20-hour rate and 1.75VPC, and 984.00Ah at the 8-hour rate and 1.80VPC. The battery has a rated voltage of 2Vdc, an internal resistance of 0.28 mΩ, a maximum charge current of 300.00A, and a maximum discharge current of 6000A. Temperature and charging conditions: at 25°C, the float charge voltage is 2.21 to 2.25Vdc and the equalization charge voltage is 2.35Vdc. The nominal operating temperature is 25°C, the allowable discharge range is -15°C to 50°C, and the allowable charge and storage range is -15°C to 40°C. Regarding self-discharge, storage at 25°C for 90 days results in less than 10% capacity loss, with a maximum storage period of 6 months; the battery should be fully charged before use. If the storage temperature exceeds 25°C, supplementary charging is required in advance. In terms of construction, the MSJ-1000 case uses flame-retardant ABS material meeting UL 94-V0 requirements. The terminals are I4 threaded copper alloy compatible with M8 bolts, with a terminal torque of 126±25 Kgf·cm, 109±22 Lbf·in, or 12.3±2.5 N·m. Dimensions: width 171.0±2.0mm, height 339.0±2.5mm, depth 471.0±2.5mm, weight 72.80kg. The product is manufactured in accordance with IEC 60896-21/22:2004 and is UL1989 certified (MH14533). It is designed for high-capacity float standby power applications, with the official application area being telecom, making it suitable as a backup power source for communication systems.
