When designing a power management system for a wireless remote sensor, it is important to choose a primary battery that last for decades under extreme operating conditions. Lithium thionyl chloride chemistry is the preferred choice due to its proven ability to deliver 25-plus years of service life.

Optimizing battery life and long-term reliability involves numerous variables, including the chemistry, the cell design, the quality of mechanical components, the purity of raw materials and the manufacturing processes employed. Shortcuts in quality can negatively impact service life.
