Sorry, but I don't believe that for I no-where can find an Apple document saying that. And my 18 yrs of exp. with Apple Notebooks is different. F.e. I have a Kanga (first PB G3) in my kitchen. Has a dead main battery and is only connected to the wall when in use. Yesterday I used the Kanga after being unplugged and without a main battery for 8 days!! Date and time showed up correctly!! So I strongly believe you are mixing up the (unplugged) lifetime of the main battery (3-5 hours is normal) and the lifetime of the PRAM battery (normally several years)! For the rest: Switching down the PRAM battery after 3-5 hours would be a redicoulus construction! And besides that, it would include a time-switch and I never have heard of or seen such in any personal computer! So I would say read my answer before again and give it a try. In case of doubt use a battery-tester (under US$ 15) or let it it test by a prof. techn. Using a voltmeter only is useless! Otherwise I woukd say, please tell us where you got that Apple wisdom saying: "....the pram will only hold a 3-5 hour charge without being plugged in and without a main battery preset."
