DEWALT DC9091 14.4-Volt XRP Battery Pack

The difference between this battery and the "regular" 14.4v DeWalt batteries is like night and day. I was always fairly pleased with the performance I got out of my original batteries, but once I picked up one of these I was convinced that the hype is justified. Right out of the box I noticed that this battery is a bit larger and significantly heavier that the regular 14.4's. Once fully charged, I slapped it in my drill/driver and was AMAZED at how much more powerful this battery pack was. I have also been impressed with the run time between charges, but since I have not yet used it to build any decks, etc., I cannot say if the battery truly lasts 25% longer (or 40% or whatever).

I highly recommend this as a quality product that performs amazingly well.

This battery is acceptable as a replacement. However one flaw is that the battery is not the same size as the original. It fits the drill fine but does not fit into the carrying case properly. It is a small flaw but other than that it works fine.

As far as batteries go, they came, they charged, they performed flawlessly. The Dewalt XRP batteries are definitely worth the extra expense for longer run-times between charges, a must-have for the professional contractor.
