Who says?
Who says that you can't recharge alkaline batteries?  This does it well.  The first two AA were deemed not rechargeable, however when I needed to do 4 this was perfect.  Three fit in and recharged quickly.  The fourth wouldn't fit in a slot and light up.  So I did three and then the last one by itself.  Now, these promptly went into the Wii and I've used them every other day since for about an hour each time.
