Li-SO2 Lithium Battery

LR series battery(Lithium Sulfur Dioxide (Li-SO2) Battery) delivered a voltage of 2.9V. The batteries have a high energy density and a good capability for delivering repeated bursts of high power. This kind of cell is mainly used in defense applications, utility metering and etc.

Features & Benefits

  • High operating voltage, stable during most of the application lifetime
  • High safety: non-flammable (but corrosive) pressurized electrolyte, quickly expelled in case of venting
  • HighesLow self discharge: less than 3% capacity loss during storage at ambient temperature before use
  • Application:
    Alarms and security wireless devices
    Mobile asset tracking
    Electronic Meters (Water, Gas, Electricity)
    Professional electronics
