Road Power 0989 Anti-Corrosion Fiber Washers; 1 Pack (2 Washers); 6 and 12-Volt

You can't go wrong with these and should place them on all vehicle battery terminals after cleaning them. They are very easy to apply; red on positive, green on negative, between the battery and the terminal, on the post. Do this quickly as the car computer may require reprogramming if you do it too slow; if that happens it is easy to reprogram, just read your owners manual (it can alter window and door lock function). Before you start blow across the vents to dissipate and vapors that could explode with sparking, wear protective glasses and protective clothes (long sleeves) and wash your hands after. The liquid in the cells is very acidic and will eat through clothes and skin. This is a good time to add distilled water to the vent holes. Do not top them off but bring the level to the bottom of the venting ring; leave space to vent the gases, there is a slot. Close the cell caps. Use a wire brush on dirty or corroded or fuzzy (usually a white or green powder) terminals and connectors. Check your electrolyte, if you know how, to see if your battery is weak or has low/bad cells. If you have a lot of corrosion, cap the vents and mix about a tsp. of baking soda in a glass of water and brush it on with a toothbrush (if you get any in a cell it will kill the battery), it will foam up if there is acid, then rinse and dry before placing the washers and terminals. Remove the ground first, place the felt washer, replace the terminal, then place the positive. Reset your clock and anything with memory (GPS). Prepare for winter. If your battery is past the expiration date, replace it so you don't get stuck somewhere. Most good batteries do not live past their expiration date and can't be relied upon. Walmart and Costco batteries seem to be the most reliable according to reviews. I get mine at Costco and do not recommend Optima.I ordered these before and ordered again for a new battery, still highly recommend them. FYI I had but then in an 04 Lexus RS330 and it had corrosion (white fuzz) on both terminals, on top of the terminals. Perhaps I should have sprayed them with terminal spray, but it is tar/grease-like. My battery also has a battery charger on it that removes plate deposits as I drive so maybe that caused it. it is the only one to do that and the only one that had a de-sulphanator on it, so this is new to me. I will sill use these to keep stuff off my batteries.

Good product. Thank you

Perfect to protect circuit when replacing batteries in a compartment

Installed these on my car's battery 15 months ago. I purchased these by mistake but figured I'd give it a try as I have corrosion on my battery terminals from time to time. After 6 months use, I found signs of corrosion on the battery. Nothing drastic or questionable, just simple signs.After about 15 months of use I needed to change out my battery. I brought it to a shop where installation was included with purchase. Upon removing the battery the mechanic complimented how little corrosion was on my battery. I surprisingly responded "Really?!" My battery terminals had a decent amount of corrosive residue around them to the point where you could blow and make a small corrosive cloud of dust. He explained that he sees cars come in here often that are caked with corrosive residue. He then went on to say the corrosion on the battery was quite a bit, but it wasn't sticking to the battery's terminals at all. A quick blow basically left everything looking fairly clean.That said, it sounds like these do a decent job. Expect some corrosive residue, but don't expect a totally clean look. In the end it sounds like this is a good product.

I actually threw them away accidently because they must have been hidden under another box

Perfect for a car battery thank you helps keep corrosion off the battery

I thought this was a 2 pack of 2 washers totaling 4 washers, but it is only 2 washers total. I think you can get them for about half that price at an auto parts store.

This is a simple solution to an old problem of corrosion of battery terminals. The product works as advertised but you could certainly make your own version with some plastic (or other non-conducting material) and a pair of scissors.Still, it is cheap enough to purchase and convenient to use.
