Saft Military Radio Battery

Dual Voltage Design

The Saft BA 5590 B/U military radio battery features a dual voltage design that accommodates a variety of uses. This non-rechargeable battery is made up of 10 LO 26 SX cells that are connected in series of five cells in each grouping. Each section can be used independently, at 12V each, or they can be connected together. Choose between a series connection, which will provide you with 24V, or a parallel connection for 12V of power, with an extended capacity. When setting up a battery connection, it is important to understand that a series formation is used to double the batteries' voltage, while a parallel formation doubles the capacity, yet leaves the voltage alone.

The Saft BA 5590 B/U dual voltage military radio battery features lithium sulfur dioxide chemistry, which is known for its wide operating temperature range. LiSO2 non-rechargeable batteries also have flat voltage discharge curves and a high capacity. An important note about lithium sulfur dioxide batteries, including this military radio battery, is that the high-pressurized SO2 requires a safety vent to prevent an explosion. The BA 5590 B/U dual voltage battery is typically used to power military radios, transmitters, and other surveillance systems. Its versatility and extreme power make this a reliable power source often chosen by the US military.
