Flat top battery adapter

Have flattop batteries that won't work in a flashlight or any other device



Looks pretty easy to fabricate these as well...maybe a neat DIY project

Perhaps with a sheet of 1/16 (0.0625) acrylic sheet and a hole saw and a few of these

Brass snap buttons

No need to solder a big ole blob on a flattop

Clever. I don’t have anything that won’t take a flat top and all of my 18650s are flat, but those look handy to keep around. I’ll have to see what I can come up with when I get back home. A thinner adapter that could be heat-shrinked to the battery semi-permanently would be easy to make and quite useful for a lot of us here that use flat pack pulls.

Or you can buy 50 magnets for the same price?

You can cut a disk out of a soda bottle cap, make a hole in the center & epoxy a magnet in.

You can put solder blobs on in about 4 seconds each .

Scuff the tops add flux and drop a blob ..next

it took you 4 seconds to drop the solder blob? :bigsmile:

The only way to do a great work is to love what you do.

I’ve used both the magnet and the blob of solder (preferred) method with great success. Nice to know that there is yet another option available though.
