  • Thionyl Chloride Lithium Battery (ER series) uses highly active thionyl chloride (SOCl2) for the positive electrode reactant. and lithium for the negative electrode reactant. The voltage is the highest among lithium primary batteries at 3.6V, and the electric energy in AA size 7000mWh, realizing high energy.
  • Self-discharge is minimized by using highly pure materials. The battery can be used in a wide range of temperatures (-55ºC to +85ºC) and is highly reliable, as fluid leakage is not a concern due to the use of Laser Weld Sealing for the complete enclosure.
    The product is especially suited for long term use, such as memory backup power supply, and as the power for electricity/gas/water meters.
  • Our Thionyl Chloride Lithium Battery is a UL (safety standard) certified part. and its safety and reliability have been proven
