DEWALT DW9116 7.2-Volt to 18-Volt Pod Style 1 Hour Battery Charger
This is an amazing little charger that literally breathes new life into your failing DeWalt batteries. It revitalizes everything from 9.6 volts through the big 18-volters, but what's so great about this charger is that not only can it be used as a standard quick charger, but if you leave a worn-down battery in for four to 10 hours, the charger conditions the battery with a tune-up mode, and at completion, it automatically converts to trickle charge, so you'll never damage a battery by leaving it in the charger too long.Diagnostics with LED indicators give you the battery status at a glance: charged, charging, power line problem, replace pack, and battery too hot or too cold. It's got a small footprint, which is always a plus, and the price is look-twice-and-rub-your-eyes cheap.--Kris Jensen-Van Heste
