KeepPower IMR18350 1200mAh High Discharge Flat Top

Note: Cells come from KeepPower in a package with two cells and a plastic storage case. You will receive two cells when you choose a quantity of one.

Here is what separates IMR cells from standard Li-Ion: 

IMR cells are a specialized Li-Mn (Lithium Manganese) chemistry specifically 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 KeepPower 18350 is the highest capacity IMR battery in this size, but it will only deliver 35 minutes of run-time on the highest power setting in a PLH, or OKW light. 

These cells do not have a protection circuit but do offer a bit more current than the protected cells we include with the complete PLH/OKW-18350 lights. These cells are for use in our 18350 bodies ONLY. Do not use two of these cells in an 18650 body the voltage will be to high and could cause damage or failure of Modlite and also Surefire light heads.
