Product details
CSB's MSV series includes the MSV-500. This model is a 2V valve-regulated sealed lead-acid (VRLA) battery that uses AGM absorbed glass mat separator technology, with gas recombination efficiency up to 99%. According to its official positioning, it is intended for large emergency and telecommunications applications and is a high-capacity, long-life VRLA 2V battery.
In terms of capacity data, at 25°C, 1.80 VPC, and the 10-hour rate, the nominal capacity of the MSV-500 is 500Ah. If the temperature remains 25°C and the voltage point is 1.75 VPC, the 8-hour rate capacity is 511.20Ah and the 20-hour rate capacity is 512.00Ah; at 25°C, 1.80 VPC, and the 8-hour rate, the capacity is 500.80Ah.
In terms of electrical performance, 150.00A is the maximum charging current of the battery, and 3000A is the maximum discharge current; the short-circuit current is 7258A and the internal resistance is 0.39 mΩ. At 25°C, the float voltage range is 2.21 to 2.25 Vdc/battery, and the equalization voltage is 2.35 Vdc/battery. After 90 days of storage at 25°C, self-discharge is less than 10%; it can be stored for up to 6 months and must be fully charged before use. If the storage ambient temperature is higher than 25°C, the timing for supplementary charge should be moved up accordingly.
In terms of construction, pure lead construction and a proprietary formulation together form the structural basis of the MSV-500. Flame-retardant ABS (UL 94-V0) is used as the case material, the I4 threaded copper alloy terminals accept M8 bolts, and the terminal tightening torque is 126±25 Kgf·cm, 109±22 Lbf·in, or 12.3±2.5 N·m. Its length, width, and height are 241.0±2.5mm, 171.0±2.0mm, and 339.0±2.5mm respectively; the overall weight is 31.20kg (68.76 lb).
In terms of temperature ratings, the nominal temperature is 25°C (77°F). Discharge can be carried out between -15°C and 50°C (5°F to 122°F), while charging and storage can be carried out between -15°C and 40°C (5°F to 104°F). Under 25°C float standby conditions, the design life is 15 years; according to the Eurobat (20°C) standard, its life exceeds 12 years, reaching the Very Long Life rating. Manufacturing complies with IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533).
Maintenance-free design is a feature of the MSV-500. It can be used in high-capacity float backup power scenarios such as telecommunications; when combined as 2V monoblocs, it can provide higher-voltage battery strings to meet the long-life, high-capacity backup power requirements of communication base stations and emergency power systems.
