Hello, nothing to do and make this 18650 Battery flashlights. Very easy to do about 5 to 10 minutes cost me nothing to make them. My local drug store give me the bottles for free and the 18650 battery fits perfect. Very ease to take out the battery and put another one etc. Dont like the on off switch but was the only one I have
Thanks for reading and sorry for my English

Very impressive. Though possible heat issues might be a concern. Those prescription bottles tend to be thin-walled. I don't mean from the little LED itself, but possibly the battery.

3xAAA flashlight conversion to 18650
convert 3xAAA flashlight to 18650




Not Bad. Here's mine



I had a few fake low capacity 18650's lying around and it would be a shame to waste them. I found this $1.6 flashlight. It is powered by 3 x AAA's in a holder and only has 3 5mm LED bulbs, but its enough for use around the house








There were several 3xAAA flashlights in the store but this one was the one where an 18650 might fit. The spring at the base had enough give and look at the long protruding positive contact






All you have to do to turn this into 18650 is
1 . remove the 3xAAA holder
2. remove the screw in the middle that is the (+) terminal (you need a small phillips screwdriver)
3. remove the brass spacer pipe from the screw
4. return the screw and screw it in all the way. It will be a little tight at the end
5. Use wire cutters and a file to file down the protruding ends of the LED leads as they will scrape and damage the top of the 18650
