Great Battery Guys & Great Battery Charger

The Optima Digital 400 battery charger resuscitated my dead battery after several months of non-use on my second try when I grounded it properly. I am satisfied with the product. The only thing that the manufacturers could improve on is to use a different font for the text in the LED display or to use thicker lines for the letters. There is a backlight button though. The Optima Battery Charger was delivered in a box that provided excellent protection against any bumps along the way. Great job Battery Guys!
