Product details

From an application standpoint, the CSB MU-1000 is officially classified in the telecommunications field and is one of the higher-capacity float backup power products in the MU series. The series evolved from MSV and MSJ, while the MU-1000 itself is a 2V valve-regulated sealed lead-acid battery. In manufacturing, it uses a proprietary formulation and pure lead construction, and with AGM (absorbent glass mat) technology, gas recombination efficiency can reach 99%. In terms of performance data, at 25°C and 1.80VPC, the MU-1000 has a 10-hour rate nominal capacity of 1000Ah; at the same temperature and 1.75VPC, the 8-hour rate capacity is 904.00Ah and the 20-hour rate capacity is 1080.00Ah; if the conditions are 25°C and 1.80VPC, the 8-hour rate capacity is rated at 888.00Ah. Its internal resistance is 0.29 mΩ, the maximum charge current is 300.00A, and the maximum discharge current is 3000A. Charge settings and temperature limits are also specified: at 25°C, the float charge voltage range is 2.21 to 2.25 Vdc/battery, and the equalization charge voltage is 2.35 Vdc/battery; the nominal operating temperature is 25°C. Discharge is permitted from -15°C to 50°C, while charging and storage are permitted from -15°C to 40°C. In terms of self-discharge performance, capacity loss after 90 days of storage at 25°C is less than 10%, and the battery can be stored for up to 6 months; it should be fully charged before being put into service. When storage temperature exceeds 25°C, recharge is required earlier. For mechanical and housing details, the MU-1000 is equipped with I3 threaded copper alloy terminals, can accept M10 bolts, and has a terminal torque of 249±50 Kgf·cm, 216±43 Lbf·in, or 24.4±4.9 N·m. The housing uses UL 94-V0 flame-retardant polypropylene. Dimensions are 303.0±3.0mm (L) × 172.0±3.0mm (W) × 497.0±3.0mm (D), and weight is 54.50kg. In terms of life, when used on float charge at 25°C, the design life can reach 20 years, and 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 characteristics and high-capacity float capability, it can handle long-duration backup power tasks such as telecommunications and maintain stable operation within the specified temperature and charge voltage ranges.
