NOCO E404 Battery Terminal Cleaner Spray, 14 oz — Product description

The NOCO E404 is a 14-ounce aerosol battery cleaner that strips corrosion off terminals, cables, hold-downs, and battery boxes. It's got a built-in acid detector so you can see where acid has leaked, and clean connections mean better current flow and less voltage leakage. Simple, cheap insurance for any lead-acid setup on the boat, truck, or RV.

Battery corrosion is one of those problems that sneaks up on you. You go to start the boat, and the terminals are crusted over with that white and blue fuzz. The NOCO E404 is a 14-ounce aerosol battery cleaner built to clean it up fast. Spray it right onto the terminals, cables, hold-downs, and the battery box itself, and it goes to work lifting off corrosive buildup.

What sets it apart is the built-in acid detector. As you spray, it helps you spot where battery acid has been leaking, so you know exactly what needs attention. Clean connections matter more than most people think. Corrosion adds resistance, and that resistance robs you of current flow and lets voltage leak away where you don't want it.

Keep a can in the bilge locker or the truck. It's cheap insurance for anyone running lead-acid batteries, whether that's your trolling motor bank, your starting battery, or the deep cycle in the RV.
