This is a Ingersoll Rand w7150, has two 20 volt lithium ion batteries that take full charge. We've owned this for a few years, currently switched over to Milwaukee platform and this doesn't get used anymore. We used this on our farm, and it did not get used a lot in comparison to being used in a mechanic/repair shop. In good shape for a used tool. The best price I can find for a new one is $566.
