Product details

The CSB MU1000S 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 a maintenance-free design. This series was developed from the MSV and MSJ, targeting larger-capacity telecommunications float standby power applications, and is manufactured in accordance with IEC 60896-21/22:2004 and recognized under UL1989 (MH14533). In terms of capacity, the MU1000S has a nominal capacity of 1000Ah, tested at 1.80VPC, 25°C, 10-hour rate. Other capacity data include 1016.00Ah at the 8-hour rate at 1.75VPC, 1040.00Ah at the 20-hour rate at 1.75VPC, and 976.00Ah at the 8-hour rate at 1.80VPC. The battery's maximum charge current is 300.00A, maximum discharge current is 6000A, and internal resistance is 0.31 mΩ. Structurally, the MU1000S uses pure lead construction with proprietary formulation elements, and the case is flame-retardant polypropylene material meeting UL 94-V0 requirements. The terminal is 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. Dimensions are length 303.0±3.0mm, width 172.0±3.0mm, depth 497.0±3.0mm, and weight is 62.50kg. In terms of operating conditions, float charge voltage is 2.21 to 2.25 Vdc/battery (25°C), and equalizing charge voltage is 2.35 Vdc/battery (25°C). The nominal operating temperature is 25°C; discharge can be performed from -15°C to 50°C, and charging and storage from -15°C to 40°C. For self-discharge, less than 10% after 90 days at 25°C; it can be stored for up to 6 months and must be fully charged before use, and if storage temperature is above 25°C it should be charged sooner. In terms of design life, the MU1000S can reach 20 years in float standby service at 25°C, and more than 12 years at 20°C under the Eurobat standard, placing it in the very long life category. This battery is suitable for applications such as telecommunications that require high-capacity float standby power, providing stable backup power support to systems in 2V cell form.
