probably 2 AH batteries, sitting in a warehouse for several years. The 25618 is a solid driver, but the new one is a 1/2" wrench anvil and driver in one. This one is better at tight spaces due to the retaining ring on the anvil on the other.
there was a model between the two, probably still a current item at Lowes, between those two (IDH181 I think?) I like the 25618 better.
If you are wanting to get set up with Bosch 18v stuff let me know, though I don't think I have a driver I could definitely get you a drill, batteries, etc.to start you off.
You're not that far from me so shipping wouldn't be fatal.
