Foam Padding Sheets with Adhesive Backing - 3/4" Thick Self Stick Neoprene Insulation Foam,2PCS 3/4 Inch Thick X 4 Inch Long X 4 Inch Wide - Closed Cell Foam Sheet Square Pad

Matches the description and the adhesive is good

They do the job of "cushioning" very well.Cutting through them requires a VERY (i.e., "razor") SHARP knife and a little patience. A suitable "x-acto" (or similar) knife will do the trick!The adhesive leaves a bit to be desired - it doesn't hold well in "warm" areas (i.e., car interior). I solved the problem by using "CONTACT" CEMENT - just make sure you glue it in the RIGHT PLACE, THE ** FIRST TIME **, or you'll never "cleanly" remove it afterwards!Otherwise, I ** DO RECOMMEND ** this stuff, with the above "caveats"... :)

I made a 3"PVC beach stand for my jetskis and use these pads on the top 4 corners (not pictured, but you can imagine) to hold the skis better. Works like a charm.

This is hard foam that will be too thick for your needs. You will need soft foam that is 1/4” thick for most battery compartments. So, keep looking. I would try an electronic store if you can find one.

Too hard to cut. Don’t buy. Wasted money.

Being the size I ordered, I can add as many as needed to accommodate toitem I need to isolate.
