Pangda 12 Pcs Battery Terminal Anti Corrosion Washers Fiber, Green, Red

It does the job

Not sure how these work but they do. I've been using these for years and never had a corroded, gunky terminal. I usually put on a new set whenever I have to replace a battery or every 3-4 years if they get oily or really dirty. Not sure if that would affect their function but since they are so cheap I just periodically replace them if it's been a while.

These work the same as the ones you get at any auto parts chain but are a fraction of the cost. If you have issues with battery terminals corroding a lot give them a shot. Also it's nice that they come in black and red because at the local stores they only seem to sell the red and green ones.

Good!

Awesome pieces

Don’t understand the concept but do like the product.

Work as expected and after several months no more corrosion has occurred. Great way to inexpensively protect your battery terminals.

These are a good fit and prevent the corrosion that sneaks up on you until it's too late and you need another battery because it didn't receive enough charge

They are pretty much as described. The pads are also precut for larger battery terminals, so you can simply pull out the inner ring to get a larger diameter hole. They install very easily. Do however take note that the extra thickness can push your battery clamp off the top end of the battery post. This is not a problem with solid battery connectors/ clamps, but if its the sheet metal types, there may not be much to grip with the upper ring of the clamp. It is too early to tell if they prevent corrosion.

Bought those as I was changing car battery. Does the job, nice that each set is packed in separate pouche so won't get dirty waiting for the next battery

Looks good, will install asap

seems to do the job

very practical
