Product details

The CSB MSJ-1000 belongs to the MSJ series of 2V VRLA-AGM valve-regulated sealed lead-acid batteries, officially positioned as a high-capacity, extended service life telecom communication standby battery series, with a design life of up to 20 years under 25°C float standby conditions and a Eurobat 20°C standard ultra-long life rating of greater than 12 years. The battery uses absorbed glass mat AGM technology with a gas recombination efficiency of up to 99%, is maintenance-free, and is manufactured with a pure lead structure combined with proprietary formulation elements. In terms of capacity, the MSJ-1000 has a nominal capacity of 1000Ah, tested at 1.80VPC, 25°C, 10-hour rate. Other capacity data include 1016.00Ah at 8-hour rate 1.75VPC, 1050.00Ah at 20-hour rate 1.75VPC, and 984.00Ah at 8-hour rate 1.80VPC. The battery rated voltage is 2Vdc, internal resistance is 0.28 mΩ, maximum charging current is 300.00A, and maximum discharge current is 6000A. Regarding charging and temperature conditions, at 25°C the float charge voltage is 2.21 to 2.25Vdc and the equalizing 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. For self-discharge, capacity loss is less than 10% after 90 days storage at 25°C, storage is possible for up to 6 months, and a full charge is required before use; if storage temperature is above 25°C, recharge should be performed sooner. Structurally, the MSJ-1000 case material is flame-retardant ABS, compliant with UL 94-V0 requirements. The terminals are I4 threaded copper alloy terminals that accept M8 bolts, with a terminal torque of 126±25 Kgf·cm, 109±22 Lbf·in or 12.3±2.5 N·m. Dimensions are width 171.0±2.0mm, height 339.0±2.5mm, depth 471.0±2.5mm, and weight is 72.80kg. The product is manufactured in accordance with IEC 60896-21/22:2004 and is UL1989 recognized (MH14533). Its design targets high-capacity float standby power applications, with official application areas being telecom communication, suitable for use as communication system standby power.
