ASP CR123A Lithium Batteries. ASP batteries incorporate a PTC (Positive Thermal Coefficient) device and pressure relief vent. If an ASP battery short circuits or discharges at currents above their design limit, the PTC causes the cells internal resistance to increase, limiting the amount of current that can be drawn and keeping the internal cell temperature within safe limits.

• 3 volts
• 10-year shelf life
• PTC pressure relief vent
