Product details

The CSB MSV-300 belongs to the MSV series of 2V VRLA-AGM batteries, with an official application area of telecommunications, and a series positioning of large-capacity, long-service-life valve-regulated lead-acid batteries for large emergency and telecom applications. Its nominal voltage is 2 Vdc, with a 10-hour rate nominal capacity of 300 Ah at 25°C and 1.80 VPC; the 8-hour rate and 20-hour rate capacities are given according to the conditions listed in the data, meeting the capacity requirements for long-duration float standby power at communication sites. This battery adopts a valve-regulated sealed lead-acid structure and absorbed glass mat AGM technology, with a gas recombination efficiency of up to 99%, and is a maintenance-free design. The positive and negative plates use pure lead construction and a proprietary formula, suitable for large-capacity float standby power scenarios. The case material is flame-retardant ABS, meeting UL 94-V0 requirements; the product is manufactured according to IEC 60896-21/22:2004 and has obtained UL1989 recognition (MH14533). In terms of electrical parameters, the MSV-300 has a maximum charging current of 90.00 A, a maximum discharge current of 1800 A, a short-circuit current of 3600 A, and an internal resistance of 0.54 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 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. In terms of dimensions, the battery length is 170.0±2.0 mm, width 150.0±1.5 mm, height 339.0±2.5 mm, and weight 18.20 kg (40.11 lb). The nominal operating temperature is 25°C (77°F), the discharge temperature range is -15°C to 50°C, and the charge and storage temperature range is -15°C to 40°C. The design life can reach 15 years under 25°C float service, and the Eurobat 20°C rating is a very long life level of greater than 12 years. In terms of self-discharge, the remaining capacity after 90 days of storage at 25°C is greater than 90%, and it can be stored for up to 6 months; it must be fully charged before use, and if the storage temperature is above 25°C, supplementary charging should be performed earlier. These characteristics make the MSV-300 suitable for standby power applications such as telecommunications that require long-term float standby, and installation and maintenance should be carried out according to the voltage, torque, and temperature conditions specified in the data.
