I was a little nervous ordering from Battery Barn, as I'd found some scandalous reviews. I'm happy to report that my replacement batteries for my Makita drill showed up MUCH faster than I expected (in 3 days) and seem to work well. I haven't used them very much yet, and will update or write another review if there's a problem. Thanks, Battery folk!
Update, Dec 2010.
Having used the new batteries for a few months, I'm disappointed. They don't hold a charge as long as my older, dying batteries, and don't seem to have as much power fresh out of the charger. I haven't contacted Battery Barn yet.
I would NOT recommend these batteries.
After contacting seller, I was told that I could exchange my batteries for another $20. Seems like throwing good money after bad.
I now get all my bats from BB bec they are not only inexpensive, but the staff is very helpful. If u buy a cam-corder battery at best buy, frys, etc, it'll cost u about 60 dls, but for that amt u can get up to two at B Barn.
