Anti-Corrosion Washers for Battery Terminals

This 20-pack of anti-corrosion washers is designed to protect battery terminals on vehicles and equipment. They fit top-post and side-post configurations to help maintain a clean electrical connection. The washers are a practical addition for anyone servicing automotive electrical systems. They are supplied new and ready for immediate use.

Corrosion Protection and Electrical Reliability

The washers create a barrier that resists corrosion buildup on terminal surfaces. By reducing oxidation they help preserve consistent voltage delivery to the starter and accessories. No power draw or thermal output is generated by these passive components. They simply support the existing electrical circuit without adding load.

Sustained Protection in Daily Operation

Under continuous vehicle operation the washers retain their protective properties over time. They do not degrade in a way that alters circuit behaviour during extended use. California Proposition 65 notices indicate the product contains chemicals known to cause cancer and reproductive harm. Buyers who require a certified non-toxic alternative should consider other options.

Questions about this item

How are the anti-corrosion washers installed on a battery terminal and what step is often missed?

Place one washer over each battery post before fitting the cable clamp, then tighten the clamp bolt; the step often missed is cleaning the post surface first so the washer makes full contact.

What maintenance or replacement will the washers need over time?

Inspect the washers whenever the battery is serviced; replace them if the coating is worn, cracked, or if corrosion appears underneath.

What limit appears first when the washers are used continuously in a hot engine bay?

The protective coating can degrade from sustained heat and acid vapour, reducing its ability to prevent corrosion on the terminal posts.
