Product details
In large-scale telecom and emergency scenarios, the 2V high-capacity, long-life battery is the official positioning for the CSB MSV-200. It belongs to the MSV series and uses a valve-regulated sealed lead-acid construction, with absorbent glass mat (AGM) technology for gas recombination, achieving recombination efficiency of up to 99%; at the same time, pure lead construction and a proprietary formula are also used in this model. This series mainly targets high-capacity, long-life emergency and telecommunications requirements.
From the perspective of life and compliance, the MSV-200 has a design life of up to 15 years under 25°C float standby service; under Eurobat 20°C conditions, its life is greater than 12 years and it is classified as Very Long Life. It is manufactured in accordance with IEC 60896-21/22:2004 and has obtained UL1989 recognition, recognition number MH14533. Its maintenance-free characteristics, combined with its high-capacity float standby positioning, make it suitable for DC power applications such as telecommunications that require long-term float standby.
Mechanically and dimensionally, the battery uses I4 threaded copper alloy terminals, accepts M8 bolts, and the terminal torque range includes 126±25 Kgf·cm, 109±22 Lbf·in, or 12.3±2.5 N·m. The case is made of flame-retardant ABS and meets UL 94-V0. The overall weight is 13.60kg, which is 29.97lb; the dimensions are length 170.0±2.0mm, width 106.0±1.5mm, and height 339.0±2.5mm.
Capacity and current data are as follows: at 25°C and 1.80VPC, the 10-hour rate nominal capacity is 200Ah; also at 25°C and 1.80VPC, the 8-hour rate is 192.00Ah. If the conditions are 25°C and 1.75VPC, the 8-hour rate is 196.00Ah and the 20-hour rate is 206.00Ah. The battery's maximum charge current is 60.00A, maximum discharge current is 1200A, short-circuit current is 2968A, and internal resistance is 0.59mΩ.
Regarding charging and temperature conditions, at 25°C the float voltage is between 2.21 and 2.25Vdc, and the equalization voltage is 2.35Vdc. The nominal operating temperature is 25°C; the allowable discharge range is -15°C to 50°C, while charging and storage are allowed from -15°C to 40°C. Regarding self-discharge, after 90 days at 25°C, self-discharge will be less than 10%, and it can be stored for up to 6 months, but it must be fully charged before use; if the storage temperature exceeds 25°C, charging must be performed earlier.
