DIANN 10pcs 18650 Battery Holder Single 1x 3.7V 18650 Battery Holder 18650 Battery Holder with Wires

I bought these to replace a couple of alkaline cells with a single 18650 in a few devices. I will need to add a single cell charge/protection circuit to these, but they work fine for what I wanted. The plastic is typical for these low priced battery cells, but these holders have soldered leads, and the 18650 cells fit fine into these holders. For the price, these are a bargain.

Good Quality holders. They seem to be made well.

Wire size is very small (27g, maybe 28, about 0.014 inch stranded) and pulls loose easily. The battery is held tightly, you'll have to use something to pry it out of the holder, or trim the sides of the holder down some.

Just the right size just the right time just the right color of wires very very nice price.

Good for my hobby. Fast shipping, good price.

These work, sort-of, for my low-current app, but anything over 1/2 amp the wires are too skinny. There WILL be voltage drop in the wires. Also- ONLY for use with cells with a + button, the contact on button-less batteries is very poor, and thats what I have ☹️

These hold the 18650 batteries securely. Cheaply made, but they meet my requirements nicely.

The batteries do fit, but are very tight. Connections work on all I've used. Bottom line, they work.
