Cant fo wrong with this
This was great to add to my yellowtop optima battery easy to install and a adjust readout on digital disply! 5 stars
Nice but the terminal wont tightned down
I purchased this product a couple months ago. I have a yellow top OPTIMA battery and the Stinger terminal wouldn't tightened up enough to stay on.
The product is well worth the money. It came in a timely fashion and does exactly what it says.
