You're talking about RTC and perhaps a bit of
static RAM maintenance. If this
RTC unit is like most of the same era, the operating voltage range is quite
wide (probably about 2-7V) and sub-1ma current draw. Chargers for this type of
application are usually very low current, so "cooking' some AA cells is a very
remote prospect. This is hardly a power-hungry project.
As a matter of interest I've checked the MC146818 datasheet and it claims
a 50?A current draw in the usual configuration with a 32768Hz oscillator.
