Review: Noco quality. - Nice protectors and a nice upgrade I assume over the red/green kind. I trust the Noco name as I have many of their battery maintainers. Do they work? I don’t know. I know batteries that I have used these on when I went to change them I saw no corrosion at the posts and batteries without them usually had some acid seepage.

## Questions & Answers

**Q: Is this a package of two or two packages for a total of four**
A: When I purchased it, it was a single package containing two battery post "washers" (a package with two total washers). I was very disappointed as I could buy the same product almost anywhere locally for less. Don't purchase this unless you can't get to a Walmart - O'reilly - Autozone - or similar store. It's very overpriced @ what I paid - 3.78.

**Q: Did the battery terminal protectors changed from black to red/green? Can anyone confirm? Picture shows black but I receive red/green one.**
A: As of May 13, 2021, my order was all black (three boxes, two washers in each box). No red or green washers... only black. Thank you.

**Q: Does it matter which terminal you place the 2 black felt pads on? I'm used to using the green/red felt pads.**
A: No, I wouldn’t think so, if they are only providing black pads.

**Q: So, are these black? Anyone bought them recently?**
A: The ones I bought were red and green.
