Authentic Power for a good price
Good price for an "authentic" Milwaukee battery. The XC5.0 has great power and endurance in my power-hungry tools like my angle grinder and circular saw.

Better choice if you can afford it
I have used DeWalt cordless for work for years until the trigger's started going bad and then had to purchase a Milwaukee M18 set and i believe it is so much better.
