Don't forget that in some cases you don't actually need to turn the
PIC off at all - with the right voltage reg, sleep mode draw is on a
par with battery shelflife. The PIC can usually pretty easily power up
other parts of the system as required. e.g. with a 9V PP3/MN1604 battery (500maH), and a micropower reg like
a 78LC50 (ON/Mot), the 30uA or so draw in sleep with WDT enabled
equates to about 15,000 hours, or about a year and a half.
