I have used these washers before on a battery that was starting to accumulate that powdery chemical reaction around the terminal. I cleaned off the powder with NOCO brand battery terminal cleaner from walmart, and reinstalled the battery with these washers. These washers are always under a dollar at walmart. It did stop the powder from forming, and the battery subsequently performed well. When I was a kid, the old guys would pour coca cola straight on the battery to remove the powder. But we also didn't use seatbelts, and you could smoke in aeroplanes, so perhaps we weren't so wise after all.

Just pour a tad bit of oil on the terminals and spread it evenly. I've been doing that for decades.

Well this is a first...
You added this from Eric Huang's List, but someone has already bought it from that list.

If you don't use these, consider spaying a little WD40 on the terminals after you have cleaned them and have reconnected the cables. Ideally, use these and use the WD40 when you do the annual maintenance.

Why not just use this, the orange spray thing works great. Don't think you're supposed to leave wd40 on battery terminals, it works great to remove grime off terminals.
