<< My second question (to Ed or whomever might know): if the voltage of new-old-stock PRAM batteries reads the full 6V, how can I test to ensure that's not a false idea of a battery's condition? I've got a bag of PB500 PRAM batteries and they all show 6V or better, but that's just touching the lead contacts with a digital multimeter for a moment or two. >> In my experience, you must measure both cells, not just the series combination of the two cells. The cells are 3.0 volts, nominal, but are a little higher when new. Each cell must measure more than about 2.25 volts for the machine to work. It is indeed possible for a cell to "reverse", and for one to measure above 2.25 volts, or even a little above 3.0 volts, while the other cell reads a negative value, with the result that the sum is below 4.5 volts, and machine won't work. -- PowerBooks is sponsored by <http://lowendmac.com/> and...
