Interesting.
"replace the [battery] BEFORE [it goes] awry."
There is no practical way doing this - replace it when is goes
awry.
Also, Bob, how do you know that Terry's battery didn't last
7 years? He had no problems with his battery - he didn't say
anything about his battery. You wrote:
Terry's battery didn't last 7 years. It simply
didn't matter until some machine condition changed
and the CUDA got garbled, and signaled a problem.
Bob, you have written quite a few times explaining the ins and
outs of the StarMax battery. At one time you considered writing
the definite article about it - I think you should - you know
the most, and post it from time to time. Some don't know about
it, others may don't remember all the details. Also, the
StarMax can be started without battery, see the message below
yours.

The battery voltage lies in parallel with the ADB voltage
available from the power supply. It's function is to supply
memory voltage to maintain the settings in the CUDA chip
section that remembers user settings for various functions
one can set for preferred and personalized machine parameter
info like the clock and screen, etc.. If a mac/starmax is
unplugged, the battery should carry the settings over until
the s/m is again plugged in. If the battery is below voltage
or dead, the settings will be garbled, and the m/s may have
serious trouble starting up the next time.
I watched many power supplies be replaced in ignorance about
the battery--and endless troubleshooting on all sorts of
symptoms. Terry's battery didn't last 7 years. It simply
didn't matter until some machine condition changed and the
CUDA got garbled, and signaled a problem.
The battery life is essentially its shelf life; internal
corrosionof the electrolyte material is inevitable, and the
battery selected in the oem was simply a long life alkaline
battery with a decent voltage drop-off curve. The power
supply is not a charger; the battery clunks along until its
insides thicken and poops on its voltage.
Changing the battery ought to follow the manufacturer's
estimate of its battery life. (Often 3 to 4 years.) I don't
care if anyone ever changes them or wants to brag about how
long their's has lasted.
Don't be cavalier about the battery.Think about ir, the
battery musty have been built in there for a reason, nicth
var?
In any case, when the battery voltage drop below the level
to keep accurate memory settins in the CUDA, they'll likely
have to be reset either from the keyboard or the little red
CUDA button inside. That takes the memory settings back to
the designer's default settings--and you'll reset the date
and such.
Thanks,
Bob Wulkowicz
