Product details

The CSB MSV-800 belongs to the MSV series and is a 2V VRLA-AGM valve-regulated sealed lead-acid battery. Its official application area is telecommunications, and the series is positioned for high-capacity, long-life standby power in large emergency and telecom scenarios. Its nominal capacity is 800Ah (1.80 VPC @25°C, 10hr-rate). At 25°C, the 20-hour rate (1.75 VPC) capacity is 820.00Ah, the 8-hour rate (1.75 VPC) is 784.00Ah, and the 8-hour rate (1.80 VPC) is 768.00Ah, allowing standby duration requirements to be matched under different discharge regimes. The battery adopts a valve-regulated sealed lead-acid structure and absorbed glass mat AGM technology, with gas recombination efficiency of up to 99%. It is a maintenance-free design manufactured with pure lead construction and proprietary elements, suitable for high-capacity float standby power applications. The product is manufactured in accordance with IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533). The case uses flame-retardant ABS material meeting UL 94-V0 requirements, helping ensure safe operation in environments such as equipment rooms and telecom sites. In terms of electrical parameters, the MSV-800 has a nominal voltage of 2 Vdc, a maximum charge current of 240.00A, a maximum discharge current of 4800A, and an internal resistance of 0.38 mΩ. 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 terminal is an I4 threaded copper alloy terminal that accepts an M8 bolt, with a terminal torque of 126±25 Kgf·cm, 109±22 Lbf·in, or 12.3±2.5 N·m, facilitating reliable connections in telecom DC power systems. In terms of dimensions and weight, the battery length is 373.0±2.5mm, width 174.0±2.0mm, height 339.0±2.5mm, and weight 50.60kg (111.52 lb.). It is a large-format 2V cell suitable for grouped installation in standby power systems in telecom equipment rooms. Its design life can reach 15 years under 25°C float service, and more than 12 years under the Eurobat (20°C) standard, placing it in the Very Long Life class, suitable for telecom and emergency power supply applications requiring long-term float standby. In terms of operating temperature, the nominal temperature is 25°C (77°F), the discharge temperature range is -15°C to 50°C (5°F to 122°F), and the charge and storage temperature range is -15°C to 40°C (5°F to 104°F). In terms of self-discharge, capacity loss after 90 days of storage at 25°C is less than 10%. It can be stored for up to 6 months and must be fully charged before use; if the storage temperature is above 25°C, charging should be performed earlier to maintain battery condition.
