Product details

The CSB MU-1000 belongs to the MU series and is a 2V valve-regulated sealed lead-acid battery using absorbed glass mat (AGM) technology, with gas recombination efficiency of up to 99%, and manufactured with pure lead construction and a proprietary formula. This series was developed from the MSV and MSJ, targeting larger-capacity float standby power applications, with official application area being telecommunications. In terms of capacity, the MU-1000 has a 10-hour rate nominal capacity of 1000Ah at 25°C, 1.80VPC; at 25°C, 1.75VPC, the 8-hour rate capacity is 904.00Ah and the 20-hour rate capacity is 1080.00Ah; at 25°C, 1.80VPC, the 8-hour rate capacity is 888.00Ah. The battery internal resistance is 0.29 mΩ, maximum charge current 300.00A, maximum discharge current 3000A. Charging and temperature conditions are equally clear. At 25°C, the float charge voltage is 2.21 to 2.25 Vdc/battery, and the equalizing 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. In terms of self-discharge, capacity loss is less than 10% after 90 days at 25°C, storage is possible for up to 6 months, and a full charge is required before use; if the storage temperature is above 25°C, recharge should be done sooner. Structurally, the MU-1000 uses an I3 threaded copper alloy terminal that accepts an M10 bolt, with terminal torque of 249±50 Kgf·cm, 216±43 Lbf·in or 24.4±4.9 N·m. The case material is flame-retardant polypropylene, compliant with UL 94-V0. Dimensions are length 303.0±3.0mm, width 172.0±3.0mm, depth 497.0±3.0mm, and weight 54.50kg. The design life is up to 20 years under 25°C float charge service, and greater than 12 years under Eurobat 20°C conditions, belonging to the ultra-long life class. This product is manufactured according to IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533). With its maintenance-free design and high-capacity float characteristics, the MU-1000 is suitable for telecommunications and other occasions requiring long-duration standby power, and can operate stably within the specified temperature and charge voltage ranges.
