I needed this for a long time

This product surpasses all my expectations. It's easy to use and doesn't require any internal battery for power. I have so many vehicles, motorcycles, four wheelers, lawn tractors, and a generator that uses 12 volt batteries that it's so nice to be able to fully test them. Great product.

Excellent tester at a great price!

Super easy to use! Clear display. Brings peace of mind -- easy to tell as a car battery gets older whether it needs to be replaced soon, as well as showing the health of the charging system. Exactly what I needed. I especially appreciate that it runs off the car battery and does not have its own internal battery. No worries about leaving it in a drawer and using it once per year!
