Wow, this is pretty one-sided. Guess I'll have to chime in on the other side. A drill without good bits is nothing but a crappy anchor. You have two batteries, and that should be plenty for most projects.
I've had a Porter Cable 19.2 volt drill and saw combo for a little over two years now. I've never run out of battery juice on a job yet, but I guess there's always the first time. This has included some pretty significant projects like building a home office in my garage.
To be fair, I've always been near an electrical outlet when completing a big project, so the one-hour charger has always been available. Yes, charging a warm battery isn't a good idea, but they cool down in about 10 minutes, then I put them on a charger.
Y'all must work a lot faster than me I guess. Heck my saw is rated to cut something like 100 2x4's on a single charge. You'd have to get with it to use up a battery in less than an hour. And if you did, it's probably time for a brew anyway./w3tcompact/icons/wink.gif
I can't help but notice that a lot of the folks advocating multiple batteries are running lower-voltage tools. A 18 volt tool with a fresh battery will work circles around any 12 volt.
Another thing, I switch one battery between the drill and saw as I'm working, while the other is charging. A little bit of a hassle, but not bad at all. When these batteries die, I'll get two more fresh ones.
In summary, if the choice is between a third battery and getting a good set of drill bits, I'd go with the drill bits every time.
