Remembering what the manual says I believe you have approximately 2 minutes
to replace the batteries once you remove them.  As I see it there are two
things you can do...
 1) Get a RAM card (one of those Smith-Coronas would be good) and put your
    stuff in there.
 2) Hope he doesn't wait more than 2 minutes before allowing you to replace
    your batteries.
 
If your calculator isn't dimming or acting weird, don't worry about your
batteries!  I'd mind what the indicator is telling me if it does come on
though.
 
Good luck on your tests, I couldn't think of a better friend to take it with
you than a 48SX, a true engineering/science student's dream!
