How to mount 18650 to the board?

Question

Batteries

The task is to attach an 18650 battery to the board without the possibility of replacement. I remember somewhere I saw such a battery with L-shaped wires to solder into the holes on the board. But I can't find it for sale. Tell?
Production will be mass-produced, so do not offer options like "fun"

Answer 1

Weld to it the appropriate electrodes (flat plates) for soldering into the board, or buy 18650 already welded. Holes in the board will have to be made rectangular in shape - with a cutter. Welded surface mount electrodes can also be used.

Answer 2

There are special holders, such or such .
Expensive? Then weld a tape / wire to the electrodes and solder it to the board. Secure the battery case with two wire clamps, they are also soldered into specially trained holes. Gluing is not an option, the battery shell is a shrink film, it comes off very easily.
You can also cut grooves in the board and fasten heat shrink through them. Unlike wire, there is less risk of overheating the battery or causing a short circuit. More reliable fastening: more contact area and the battery is guaranteed to be tightly pressed to the board. But a little more expensive.

Answer 3

And do you consider the option to fill with a compound?
