Product Details

The Equus 3721 Cigarette Lighter Battery Tester provides a convenient way to monitor your vehicle's electrical system health without opening the hood. This plug-and-play diagnostic tool gives you instant voltage readings and battery charge status through your vehicle's 12V power outlet.

Key Features:

  • Simple plug-in design connects directly to cigarette lighter or power receptacle for immediate voltage monitoring
  • LCD digital display shows precise voltage measurements with easy-to-read bar graph indicating current battery charge level
  • Monitors both battery voltage and charging system performance to help diagnose electrical issues
  • Designed specifically for 12-volt negative ground systems found in most cars, trucks, and SUVs
  • Compact design stays out of the way while providing continuous system monitoring

This battery tester helps you identify charging system problems, weak batteries, and electrical issues before they leave you stranded. The bar graph display makes it easy to see at a glance whether your battery is fully charged, needs charging, or may need replacement.

Great price, good e-mail communication and fast shipping. Positive experience with Autoplicity so far.

Prices are great on this site. The layout and checkout process are easy to use; Google checkout is definitely a plus. Shipping could be a little faster, especially if they had drop ships from their supplies for items not currently in stock. Overall good service and no problems.

I bought this item for my fiance and he loves it! He was completely happy with the price we paid...

Fast order

I have had a very good experience with Autoplicity and will look for more parts here. I called Customer Service and they were very good and accurate with me. It was easy, they were very nice, immediate response, and great price.

Good site easy to search for and find parts. The lowest prices on almost every part I have been able to find for my truck.
