How many amp hours per battery?

these are 2.0 amp hour batteries. They are 1/2 amp hour larger than the standard compact 20v max but are the same physical size.

I just got new dcb203-2 batteries but they do not have xr on the batteries or the packaging (clam shell). are these good batteries?

The XR was dewalts way of saying it was a higher capacity battery before they made the 3, 4, 5, 6 amp hour batterys. Now days the xr is referencing a brushless motor tool. The bottom of the line drill comes with 1.3 ah batteries so these being 2.0 is a decent boost in capacity.

Besides battery life do these perform as well for high draw devices like the circular saw as the 4-5ah battery?

I use them in my impact and drill and jig saw they work great in them I use the 4-5 amp batteries in the circular saw only because of the high amp draw
