Saft LS14500 Batteries are unique high-powered batteries aimed solidly at industrial use. Although they are the exact same size as a standard AA battery, Saft LS14500 batteries have a nominal voltage of 3.6V.These high energy density batteries use lithium-thionyl chloride (Li-SOCI2) which results in much higher capacity, a stable voltage through almost 100% of the battery's life, and a self-discharge rate of less than 1% over prolonged storage periods.
