battery strength
apple July 16th, 2004
a quick command i found online to check your current battery capacity on your powerbook. run this from within terminal application:
ioreg -l | grep -i IOBatteryInfo
based on different postings from the thread on macnn it appears that if you have a 12” your capacity should be around 4200, 15” around 4500, and 17” around 5800.
i’ve always though that my battery was a bit weak, and this proves it. my capacity from the command was:
“IOBatteryInfo” = ({”Capacity”=3432, “Amperage”=1200, “Current”=3432, “Voltage”=12481, “Flags”=1090519045})
where it should be around 4500, it’s instead 1000 less than that, yikes. right now i get around 2.5 - 3.0 hours if i turn my screen down to about half. in the next few months i’ll likely need a new one, just in time to place my airport express order.
