Product details

The CSB MU1000S is a 2V Valve Regulated Sealed Lead Acid battery in the MU series. It utilizes Absorbent Glass Mat (AGM) technology, achieving gas recombination efficiency of up to 99%, and features a maintenance-free design. Evolving from the MSV and MSJ series, it primarily serves higher-capacity telecom float backup power requirements. The product is manufactured in accordance with IEC 60896-21/22:2004 and is UL1989 certified (MH14533). In terms of capacity, the MU1000S has a nominal capacity of 1000Ah, rated at 1.80VPC, 25°C, 10-hour rate. Additional capacity data includes: 1016.00Ah at 8-hour rate, 1.75VPC; 1040.00Ah at 20-hour rate, 1.75VPC; and 976.00Ah at 8-hour rate, 1.80VPC. The battery has a maximum charge current of 300.00A, maximum discharge current of 6000A, and internal resistance of 0.31 mΩ. In terms of construction, the MU1000S features pure lead construction and proprietary formulation elements, with a flame-retardant polypropylene case meeting UL 94-V0 requirements. The terminal type is an I3 threaded copper alloy terminal, compatible with M10 bolts, with a terminal torque range 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 62.50kg. In terms of operating conditions, the float charge voltage at 25°C is 2.21 to 2.25 Vdc/battery, and the equalization charge voltage is 2.35 Vdc/battery (25°C). Nominal operating temperature is 25°C; discharge can be performed from -15°C to 50°C, while charging and storage can be performed from -15°C to 40°C. Self-discharge characteristics are: less than 10% self-discharge after 90 days storage at 25°C, with a maximum storage period of 6 months; a full charge is required before use; if storage temperature exceeds 25°C, charge in advance. In terms of design life, the MU1000S can achieve 20 years in 25°C float standby service; according to Eurobat standards, it exceeds 12 years at 20°C, reaching the very long life classification. In a 2V cell format, this battery provides stable backup power support for applications such as telecom that require high-capacity float backup power.
