Porter Cable 20v Battery Adapter

This is for the Porter Cable 20v battery and includes the two-pin plug for use with Tigers Teeth Multi Blade Grinders. NOTE: Porter Cable does this weird thing where some high amp-hour batteries have a rectangular plastic tab (about 1/8" high and 1/2" long) on top of the battery. Some of their other batteries don't have it. Anyway, that tab would need to be shaved down for the adapter to fit. I'm not sure why they put that tab on there, it doesn't seem to do anything.

The battery shown is not included.
