When messing with dry cells - batteries if there is more than one - pay a lot
of attention to the mounting parts. A cell may test good with a voltmeter but
it may not make a good connection with the springy metal parts in its holder.
Those cells are very lightly loaded as used in the computer.

No, a voltmeter is useless! You'll need a battery-tester (10/15 $/€ ?)!
I believe Jo is correct. A voltmeter tests

Perhaps the "brand new ones" are simply to old!
For example: A few weeks ago, I got for free 12 cards, each having 12 x 3v

I have Macs that have new and good PRAM batteries but a lot of times the
machines act like the PRAM battery is bad. Is there a AHT or something like one
that tests that section of the machine and system? It always seems to be a crap
