Query: SAVE LOTS OF MONEY AND THE ENVIRONMENT AT THE SAME TIME

In this day and age it is hard to understand why everyone isn't using rechargable batteries. I own about 6 packs of these batteries. They are wonderful. I bet I have saved hundreds of dollars so far and keep saving. Why pay $4.00 to $5.00 for one pack of batteries that get used once and thrown away when you can purchase these and reuse them 1000 times. I absolutely refuse to by disposable batteries for the most part. It is true that they don't quite have the power of normal energizer alkaline batteries so they might be an issue for certain things that use a lot of power. For example Digital Camera's take a lot of power. But for the most part these work really well and I have used them for 3 - 4 years now. I highly recommend them to everyone.
