Product details
The CSB MSJ-150 in the MSJ series is a 2V VRLA-AGM battery officially listed as suitable for the telecommunications field. This series focuses on VRLA 2V high capacity and long service life and belongs to the backup battery series; when used in float charge at 25°C, the design life can reach 20 years, and under the Eurobat 20°C standard it is classified in the very long life category of greater than 12 years. Its construction uses a valve-regulated sealed lead-acid design combined with absorbed glass mat AGM technology, with gas recombination efficiency of up to 99%, maintenance-free operation, and the use of pure lead construction and proprietary formulation elements.
In terms of capacity, the MSJ-150 has a nominal capacity of 150Ah at the 10-hour rate at 25°C and 1.80VPC; under 25°C and 1.75VPC conditions, the 8-hour rate reaches 156.80Ah and the 20-hour rate is 162.20Ah; at 25°C and 1.80VPC, the 8-hour rate is 152.80Ah. The battery has a nominal voltage of 2Vdc, a maximum charge current of 45.00A, a maximum discharge current of 900A, a short-circuit current of 2848A, and an internal resistance of 0.54 mΩ. For communication backup scenarios requiring long periods of float-charge standby, these parameters are quite suitable.
Charging and temperature conditions are as follows: at 25°C, the float charge voltage is between 2.21 and 2.25 Vdc/battery, and the equalization charge voltage is 2.35 Vdc/battery. The nominal operating temperature is 25°C, the discharge range covers -15°C to 50°C, and the charge and storage range is -15°C to 40°C. For self-discharge, after 90 days at 25°C, self-discharge is less than 10%, and the battery can be stored for up to 6 months; it must be fully charged before use, and if the storage temperature exceeds 25°C, it should be charged earlier.
In terms of construction, the MSJ-150 case uses flame-retardant ABS material and meets the UL 94-V0 rating. 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. The external dimensions are width 106.0±1.5 mm, height 339.0±2.5 mm, and depth 170.0±2.0 mm, with a weight of 12.80 kg (28.81 lb). The product is manufactured in accordance with IEC 60896-21/22:2004 and is UL1989 recognized (MH14533).
Overall, the MSJ-150 provides 150Ah-class capacity in a 2V cell format and is aimed at high-capacity float-charge backup power applications such as telecommunications; with its long-life design and maintenance-free AGM construction, it is suitable for long-term float-charge standby use under nominal 25°C conditions.
