Product details

The CSB MU-1000 is a 2V valve regulated sealed lead acid battery in the MU series, featuring a gas recombination efficiency of up to 99%, AGM technology (Absorbent Glass Mat), and a pure lead structure with a proprietary formulation. Developed from the MSV and MSJ series, it targets larger-capacity float-charge backup power applications, with telecom officially designated as its application area. In terms of capacity, at 25°C and 1.80VPC, the MU-1000 provides a nominal capacity of 1000Ah at the 10-hour rate; at 25°C and 1.75VPC, the 8-hour rate capacity is 904.00Ah and the 20-hour rate capacity is 1080.00Ah; at 25°C and 1.80VPC, the 8-hour rate capacity is 888.00Ah. The battery has an internal resistance of 0.29 mΩ, a maximum charge current of 300.00A, and a maximum discharge current of 3000A. Charging and temperature conditions are also clearly specified. Float charge voltage at 25°C is 2.21 to 2.25 Vdc/battery, and equalize charge voltage is 2.35 Vdc/battery. The nominal operating temperature is 25°C, the discharge temperature range is -15°C to 50°C, and the charge and storage temperature range is -15°C to 40°C. For self-discharge, capacity loss after 90 days at 25°C is less than 10%, and the battery can be stored for up to 6 months; it must be fully charged before use. If storage temperature exceeds 25°C, supplementary charging is required sooner. In terms of construction, the MU-1000 features I3 threaded copper alloy terminals that accept M10 bolts, with a terminal torque of 249±50 Kgf·cm, 216±43 Lbf·in, or 24.4±4.9 N·m. The case is made of flame-retardant polypropylene material and complies with UL 94-V0. Dimensions are 303.0±3.0mm in length, 172.0±3.0mm in width, and 497.0±3.0mm in depth, with a weight of 54.50kg. Under 25°C float-charge conditions, the design life is up to 20 years; under Eurobat 20°C conditions, it exceeds 12 years, placing it in the very long life category. The product is manufactured in accordance with IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533). With its maintenance-free design and high-capacity float-charge characteristics, the MU-1000 is suitable for telecom and other applications requiring long-duration backup power, and can operate stably within the specified temperature and charge voltage ranges.
