Thanks for the link! Please post your results. (I'm particularly interested in the stand-by / self-discharge performance.)

I narrowly escaped a battery leak disaster with my 41 last week and I'd like to find a reliable rechargeable alternative.

The motivation for getting these was also to avoid battery leaks. My only test will be to watch when the battery indicator comes on. I don't use this calculator much, so it might be a while. I suppose I could hurry up the process by putting the calculator into an infinite loop.

For new batteries I usually cycle them through charging and draining on my charger as it sometimes take a few cycles to break them in. I haven't done that with these. Maybe an infinite loop would be a good idea.
