Product details
The MSV-800 is a product in the CSB MSV series, a 2V Valve Regulated Sealed Lead Acid (VRLA-AGM) battery designed for the telecom sector. This series emphasizes high capacity and long life, specifically built for large-scale emergency and telecom backup power applications. Its rated capacity is 800Ah (10hr-rate, 1.80 VPC @25°C); at 25°C, the 20-hour rate (1.75 VPC) capacity reaches 820.00Ah, the 8-hour rate (1.75 VPC) is 784.00Ah, and the 8-hour rate (1.80 VPC) is 768.00Ah—users can match the required backup duration based on different discharge regimes.
This battery utilizes Absorbent Glass Mat (AGM) technology combined with a valve regulated sealed lead acid structure, achieving a gas recombination efficiency of up to 99%. It features a maintenance-free design and is made with a pure lead construction and proprietary elements, making it suitable for high-capacity float backup power applications. It is manufactured to IEC 60896-21/22:2004 and recognized under UL1989 (MH14533). Flame-retardant ABS material is used for the casing, meeting UL 94-V0 requirements, which contributes to safe operation in environments such as data centers and communication 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 ranges from 2.21 to 2.25 Vdc/battery, and the equalization charge voltage is 2.35 Vdc/battery. The terminal uses an I4 threaded copper alloy, accepts M8 bolts, and has a terminal torque of 126±25 Kgf·cm, 109±22 Lbf·in, or 12.3±2.5 N·m, enabling reliable connections in communication DC power systems.
Dimensions and weight: the battery is 373.0±2.5mm long, 174.0±2.0mm wide, and 339.0±2.5mm high, weighing 50.60kg (111.52 lb.). It is a large-format 2V cell, suitable for group installation in backup power systems of telecom equipment rooms. Its design life can reach 15 years under 25°C float charge conditions, and exceeds 12 years under the Eurobat (20°C) standard, qualifying as Very Long Life, suitable for communication and emergency power supply applications requiring long-term float standby.
Operating temperature: nominal temperature 25°C (77°F), discharge temperature range -15°C to 50°C (5°F to 122°F), charge and storage temperature range -15°C to 40°C (5°F to 104°F). In terms of self-discharge, after 90 days of storage at 25°C, capacity loss is less than 10%, and storage is possible for up to 6 months; a full charge is required before use. If the storage temperature exceeds 25°C, charging should be done earlier to maintain battery condition.
