This is an 18V lithium-ion cordless drill that was given a good rating by Fine Woodworking. Normally I don't pay much attention to those tests, but this one drilled the most holes, drove the most screws, and pretty much did more than whatever else the guy tried. So since I need a new one, why not this one. Here's the real question...right now Amazon has it listed at what seems to be a competitive price, free shipping, and a free battery offer. So that would make a total of 3 batteries with the 2 that come with it. I've read that lithium-ion batteries have a limited shelf life. This is from Wikipedia:
"the charge in an older battery will not last as long as in a new battery due solely to its age", ie, no charge/discharge cycles.
So what's the advantage of 3 batteries if the third one is shot by the time I need it.
I'd be interested in hearing of anyone's personal experience with this phenomenon.
