I am a little sad to admit that we have never used rechargeable batteries, mostly because I don't know anything about them. But, this one looks pretty cool! I really like how you can see the display from across the room, and know exactly how much time you have left! And, it has a bad battery alert if you insert the wrong kind of battery. I can totally see Mommy doing this in a sleep deprived moment when Thomas the tank engine isn't working. It automatically shuts off on it's own!
