I have several 18v Dewalt drills, was cheaper to buy another drill than a pair of batteries, and now I am down to about 6 batteries. Was wondering if anyone has bought any of the non-dewalt batteries I see on ebay, and amazon. Now a pair of new 18v is priced at 149, and none in store. The singles are 99 each. Was reading reviews of the new 20v drills, and most reviews said at least one battery had failed in the first 6 months, so thinking about staying with the 18v nicads for now. Not sure I am up to rebuilding my own batteries.
