Review on Efficient Bosch PS11 102: Maximize Performance with 12 Volt Lithium Ion Capacity by Joe Gosa

I really liked this bit until it suddenly stopped working about 18 months after buying it. I didn't use it very much so I didn't realize it was broken until after the warranty period gone. It worked fine once I had it removed. When I tried to use it a few months later, it was dead as a doornail. The battery appears to be fully charged (the charge indicator is solid green). But when the battery is inserted into the drill, the charge indicators on the drill will not light up and the drill will not charge at all.
