I have one in JD colors, made by Hitachi. I think it is 12 volts, but I'm not sure. It is about the handiest thing around here, it gets used all the time. Battery life per charge and total life has been very good-tool is at least 3 years old, batts still seem as good as when it was new. If it got wrecked, I would buy another in an instant.

Bought the JD because the JD tech was out doing some warranty work on our skid steer, he was using one and had a Snap-On 3/8 cordless laying in his toolbox. I asked him why, he said the Snappy was nearly useless compared to the green one.

I don't know the torque rating, but you have to be careful or you can strip the threads off a 3/8 grade 5 bolt.
