What I am saying is the other lights DO NOT distinguish between rechargeable and primary batteries any more than a 357 pistol distinguishes between .38 Special and .357. You can use both, the tool doesn't distinguish between the two. Now, if Smith & Wesson made a model 686 that automatically adjust the front sight for which ammo was put in the gun...
Let's see what it takes for an HDS to tell the difference. Turn the light on (just a push of the button), now unscrew the battery compartment and put in the new primary or charged IMR, ICR, INR and screw the battery compartment back on. Done.
If turning the light on before changing the battery is too complicated, one can sit and wait for 60 seconds. I personally, being an impatient sort of fellow, simply prefer to turn the light on first so I don't have to wait.
