Description

If you’ve ever popped the hood on an older tractor and found those battery terminals looking like they’ve been through a war—green and white crusty buildup everywhere—you know how acid corrosion can eat away at your electrical connections. These simple red felt washers slip right under your battery cables and work around the clock to soak up acid vapors before they can turn your terminals into a corroded mess.

What You’re Getting

Absorbs battery acid vapors that cause corrosion and power loss
Prevents electrical leakage that drains your battery overnight
Reduces overcharging issues that waste fuel and shorten battery life
Bright red color makes it easy to see they’re in place during maintenance
Bulk pack of 100 washers keeps your shop or barn well-stocked

Built for Real Farm Work

These washers work on any tractor, truck, or piece of equipment with standard battery posts. Whether you’re maintaining a fleet of older tractors that seem to eat batteries, or you want to protect the electrical system on your newer machines, these washers are a simple insurance policy against costly electrical problems.

Made to Last

The felt material is designed to absorb and neutralize acid fumes without breaking down or falling apart. Unlike some cheap alternatives that crumble after a season, these washers stay put and keep doing their job through temperature swings and vibration.

Good to Know

Install one washer under each battery cable when you’re connecting terminals. If your battery posts already have corrosion, clean them with baking soda and water first, then dry thoroughly before installing the washers. Replace them whenever you service the battery or notice they’ve become saturated.
