Recycling Vaping Batteries

[VapieDan]

For a while now I have been using my older 18650 batteries in flashlights. The thought just occurred to me flashlights may not have a cut off at a specific low voltage. I have never run mine down for long and I was just wondering if this bears monitoring.

Both models of18650 flashlights I own (Nitecore MH2C and xtar B20) have regulator circuits that let you choose brightness levels as well as a strobe/flash mode. I've not run batteries down real low in either of them -- that would be hard to do give the run time they have -- but I can't imagine that they wouldn't have a cut-off.

I agree with you long run time. I rarely get them even low. However I have been know to leave a light on by mistake from time to time. Thanks for the reply!

I have one of those 5000+ lumen flashlights that uses 18650's. There's a difference in brightness when the battery gets low, but you notice it more when you swap in a freshly charged bat. It's like switching to brights in your car.

I tend to swap in a freshly charged cell often and put the old one in the charger.

A walk on the beach is a world of difference with a Lithium flashlight!
