Gear You Need

Wear safety glasses and rubber gloves. Use insulated tools. Keep a fire extinguisher nearby. No loose clothing or jewelry that could touch terminals.

Work Environment Tips

Charge in a cool, dry spot. Good airflow prevents hydrogen gas buildup. Never charge inside the car. Turn off the engine and all accessories first.

Example: Last winter, my buddy skipped gloves. A spark burned his hand. Don’t be him—gear up!

Preparing Your Car Battery

Before connecting your Cat charger, check the battery. Is it dead or just weak? Prep saves time and hassle.

Testing the Battery

Grab a multimeter. Set to DC volts. Touch red to positive (+), black to negative (-). Good battery reads 12.6V. Below 12V? It needs charge. Learn more in our how to use a multimeter to test a car battery article.

If it’s bad, like under 10V after rest, consider replacement. See how to tell if a car battery is bad.

Cleaning Terminals

Batteries get corroded. Mix baking soda and water. Scrub terminals with a brush. Rinse and dry. Tighten loose cables.

• White powder? That’s corrosion—neutralize it.
• Use a terminal cleaner tool for shine.
