I have some batteries I salvaged from laptops and they are not button top. Will they still work in my lights?

If your light has a raised outer ring around the positive connection ,
that is done for polarity reversal protection .
Only raised-button batteries will work in those lights.

depends on whether your lights have physical reverse polarity protection that can tend to keep flat tops from making contact :/

Is there a way to put a button or spacer on them? I have about 100 batteries.
