So far they have excelled above the rest
We do a lot of remodeling and additions. so far the power and length of use has been far superior to the 18v dewalt tools we have used for years, and still do some. We have not used much in the extreme cold or hot to see if they out perform the others in that area.

It's a battery, not too much to talk about.
this is the 4Ah battery. We have the entire range of batteries from Dewalt 20V line. We bought this as a package deal which was cheap otherwise we would recommend the 5 Ah battery for large size and the 2 Ah battery in the small format. This 4 Ah is the same general size as the 5. It doesn't last as long as the 5 but does well. We have no real preference on this. If the 5 was the same price as the 4 we would have purchased them instead. They can power all the higher demand tools with ease. No frills it's a battery.

My mistake that I thought I had selected a 2-pack to purchase or I would not have purchased this, as this makes the battery much more expensive. You have the 2-packs for not much more than a single battery.
