If the battery goes down really low, yes you can lose the date and 
time.  These models have a super cap rather than a PRAM battery. 
This means they can't operate the PRAM / Clock or keep up the memory 
in sleep very long.  It is intended to provide power only while 
changing the battery.  But they have a much longer component life 
than a battery.

Not sure about the higher chime.

I'd reset the clock and not worry about it.  If it happens again 
after the deep battery discharge that would confirm  the theory.
