We have tried several battery terminal cover types but none seem to work. Does anyone have any suggestions?
We just use electrical tape.
Heat shrink works really well.
Electrical tape to cover all exposed metal in the terminal area. You should also orient the connector so that nothing extends beyond the “vertical” edge of the battery. This will reduce the chances of abrasion on the insulating tape. I’ll try to attach a couple of pictures.
We’ve found that using electrical tape, color coded to the terminal has worked wonders for us.
