Rechargable batteries will not last as long as normal AA's, but, of course, can be recharged, and should last over a year.
The batteries in an Xbox 360 controller are rechargeable. When full charged, they will last several days. The batteries themselves are meant to last the life of the controller.
The batteries are over the counter watch batteries and they last twice as long as the battery put into the walker
No, it will not harm your shaver. However, it is a small possiblity that your shaver will rotate slower than when using 3V batteries.
