This battery was installed in my car because I don’t drive it very much and we want to make sure the car battery does not die. This is a useful product and was easy to install by a car mechanic.

I bought this partly because I had read recent reviews that it was made in the USA. I am committed to supporting American businesses making quality products in favor of those companies who merely import junk from China to make a fast buck at the expense of our economy and jobs.
What a disappointment. Surely, we can make battery charges in the United States of America?
Can’t we?
What is the world coming to?
I will update my review in 5 years or when this item stops working. Whichever comes sooner. It’s my guess I’ll be back within 24 months, judging from the usual apalling quality of Chinese products.

This charger was recommended to me by a friend. I got it at a better price than my friend did and it’s exactly what I wanted.
