Subject: Battery Recharger

I have seen battery rechargers that work with rechargable as well as 
regular alkaline batteries.  I always thought alkaline batteries 
couldn't be recharged. So, can the rechargers actually work as they 
claim; if so, how?
If the rechargers actually do work, would the alkaline batteries 
deteriorate after repeated recharges--for example, would the 
batteries' capacity decrease over time?
