Review: Easy to use and understand. Well made, and does everything you need it to do. - The connectors seem really well made and are larger than what you find on a lot of battery chargers which make fitting on the battery terminal much easier. The device powers on quickly and was very simple to use. I didn't even read the directions the first time I used it. Very easy to get the information you need on batteries state of charge and perform a cranking amp test. I think I'm going to use this on all my batteries before winter every year and hopefully save myself the hassle of getting stranded which the first cold snap that finishes off an already weakened battery.
