Here is what separates IMR cells from standard Li-Ion:
IMR cells are a specialized Li-Mn (Lithium Manganese) chemistry specificaly designed for high-drain applications. While they excel at delivering massive discharge rates, their capacity is much more limited than a Li-Ion of the same size. The AW 18350is the highest capacity IMR battery in this size, but it will only deliver 15 minutes of run-time on the highest power setting. Can't have everything right? I highly recommend buying two and having one for a backup.
NOTICE: Using a "standard" (non-IMR) battery in an Alpha Shorty may cause a fire and explosion. They cannot handle the massive current drain the light demands.
AW Batteries are the best flashlight batteries in the world, period. That's why I sell them. Accept no substitutes.
