Product details

The CSB MSV-1000 belongs to the MSV series and is a 2V valve-regulated sealed lead-acid battery using AGM absorbed glass mat technology, with gas recombination efficiency of up to 99%, and a maintenance-free design. This series targets high-capacity, long-life emergency and telecom applications, and the official application area of the MSV-1000 is Telecom. In terms of capacity, the MSV-1000 has a 10-hour rate nominal capacity of 1000Ah at 25°C and 1.80 VPC; at 25°C and 1.75 VPC, the 8-hour rate is 984.00Ah and the 20-hour rate is 1030.00Ah; at 25°C and 1.80 VPC, the 8-hour rate is 960.00Ah. The battery internal resistance is 0.38 mΩ, the maximum charging current is 300.00A, and the maximum discharge current is 6000A. Regarding charging and temperature conditions, 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 charging and storage temperature range is -15°C to 40°C. Self-discharge is less than 10% after 90 days of storage at 25°C, and it can be stored at 25°C for up to 6 months, requiring a full charge before use; if the storage temperature is above 25°C, it should be charged sooner. Structurally, the MSV-1000 uses pure lead construction and a proprietary formula, with a flame-retardant ABS case meeting UL 94-V0. The terminals are I4 threaded copper alloy terminals that accept M8 bolts, with a terminal torque of 126±25 Kgf·cm, 109±22 Lbf·in, or 12.3±2.5 N·m. The dimensions are length 471.0±2.5mm, width 171.0±2.0mm, height 339.0±2.5mm, and the weight is 64.40kg. In terms of life and compliance, the MSV-1000 has a design life of up to 15 years in float standby service at 25°C, greater than 12 years under Eurobat 20°C conditions, placing it in the Very Long Life class. The product is manufactured according to IEC 60896-21/22:2004 and is UL1989 recognized (MH14533). These features make it suitable for standby power applications such as telecom that require long-term float standby.
