I wish that someone had told me about this earlier! We are big fans of rechargeable batteries, especially with a toddler. We had been using a AA and AAA battery charger, but it has been acting up recently - the batteries have been getting really hot. I had some Best Buy gift cards, and went to work on finding a replacement.
On the Best Buy website, I ordered the Universal Compact Battery Charger for $34. I received the Family Charger, and it is awesome! It can charge up to 8 AA, 8 AAA, 4C, 4D or 2 9V NiMH rechargeable batteries, and has a really nice digital status indicator that tells you when your batteries are ready. Another nice feature is that the unit does not begin to charge until the lid is closed.
We are going to purchase some C, D, and 9V batteries soon. I can say that it has done a great job with the AAA and AA batteries we currently have - no more hot batteries!
I would highly recommend this product to anyone who has kids. Although I have only had this product for a few weeks, it seems to be built well and looks like something that will last a long time (as opposed to the past couple of battery chargers we've had).
My only regret is that I wish I had known about the rechargeable D batteries a couple of years ago when we had a battery-powered swing!
