I have just come across this term & noted some reviews that measure this characteristic with other comments such as "I unscrew the cap to properly switch off".
I own two LED flashlights using single Li-ion 1865 batteries & each sits "ready for use" but in fact are used only occasionally. They seem to sit without noticeable battery drain for months at a time.
I also own one a Sky Ray 3XT6 which uses two 1865 batteries.
I have observed that it generally cuts out unexpectedly after relatively little use & I then discover typically one battery is "low" whilst the other is of the order of about 3.6V.
My question is why do the batteries not discharge approximately equally & is parasitic drain responsible for the low life between charges?
