Making Odd Sized Batteries

Should you go (nevertheless) with soldering tabs, you must use resistance welding.

I don't electrically fasten them. I clean them with alcohol, stack them and wrap them in tape. Never had any trouble, have used Yashica rangefinders this way until the batteries died. As a plus, I can wrap LR44s with tape to make them whatever diameter I need. I adjust the length by adding a piece of aluminum dowel cut to size. Yes I know that causes a reaction between the two metals and a buildup of corrosion that will eventually break contact. It's never been a problem in practice. Yes a length of brass would be better, but I had an aluminum dowel the right size sitting beside my desk.

this is on the money!

keep it simple. LR44s and other "button cells" are cheap by the dozen on amazon. just stack m up.

tabs are spot welded... never heat a battery to solder it!

Just stack them, no need for 'welding'

I buy these already made, no wires, no welding

Buy them by the 100 pack

and if you really want to, the small rechargeable spotwelders on amazon for ~$50 work far better than they should.
