I wouldn't use AA batteries, but rechargeable AA cells instead... Think of the environment!

First I laughed at chargeable chargers - out lout - but if they pack enough power, they just might save your week...

How about solar cells? Limited use cases, but hey, free power! Also widely available...
I mentioned AAA (AA is more bigger than AAA)

Still, you are right about using battery cells.

By the way, I noticed that I didn't mention what I attended to in my previous post.
I was thinking of replacing Nokia original battery with 4 rechargeable AAA cells and connecting through a circuit where it also takes a power from a solar cells that is mounted on the battery cover (Or mounted in any better place?).

After all, I am sure people won't like to do this mod while their warranty remains unless someone made this in a good product and replaceable.
