That is the main reason I selected this light over many of the others available. Very nice to just have a spare charged 18650 in the bag and run the battery all of the way down before you swap. No more mental calculations like I rode it 3 times since last charge for a total of about 40 minutes so I only have 30 min left and my next ride is 50 minutes si I have to wait and recharge the light before I ride. That is all done with. I just go and ride and when it starts to falter I switch to a fresh cell and put the old on the charger when I get home.
