Yes, several times now. I purchased the 24V system years ago and when the first set of batteries died (after 6 years), i called them up...had to take the batteries, charger and drill to HD at the time, and they tested and said - you need new batteries (no shirt shylock). They sent out a new set and i was good to go for a year. that set died...they replaced them again (4 years on that 3rd set); and when they wouldn't take a charge i took everything back to HD and they said, hey, you don't have to bring them here anymore...just call the 800 number; which i did. They only had one (?) in stock and shipped it right out. called them a couple of months later and they shipped the second one. That was a couple of years back and they're still good. They said to just recycle the previous set. I keep them registered and they have never complained one time about replacing them. Contrary to some complaints i have read, they have been good over the phone and on their web site. I love that heavier than a brick 24V 1/2" drill (set came with circ saw, recip saw, and a light...should have purchased the sabre saw, too). I won't buy the new batteries from anyone...because you can't register them for the LSA. Keeping this baby until one of us dies first.
