Not "quickly". I believe these lithium batteries will last up to 10 years
in that mode. (I looked up some battery charts recently on a manufacturer's
site.) The power drain to keep the PRAM alive is minute. Unfortunately when
they finally do die the odd-sized batteries (3.6V, 1/2 AA) from Apple for
most Macs are absurdly priced, about five times a similar (but
incompatible) lithium camera battery. Haven't found any compatible
batteries where I live, so when I start up my old Quadra it's always 1956
... a new battery would be about half the going price of the whole machine.
