Many parts stores sell these felt type rings as corrosion control the install under the battery terminals, what a lot of people don’t realize is that battery posts are tapered so if you don’t seat the terminal all the way down on the battery post the terminal can not tighten properly. Some times this leads to over tightening of the terminal which can stretch it out. We’ve seen an up tick in this happening over the past several months leading to no starts or discharged battery’s and ruined battery terminals. Rather than using these rings it’s better to use an anti corrosion spray, we’ve found fluid film to be the longest lasting corrosion preventer. Just a little PSA to try and save some battery terminals!
