This product is very easy to use. It is powered by the car battery you are testing. No additional batteries are required. Just connect to the terminals and read the number. So far it works great. Good value for money. Nice digital display.

This product works, tells me my battery won't hold a full change and after 2-3 weeks the car wouldn't start, the battery was dead.
