Crazy battery numbers I'm getting crazy battery numbers in my ancient (but fully operational) PowerBook G4 2005 running Mac OS X Tiger 10.4.11. The battery is very nearly shot. The numbers reported by coconutBattery also reported by System Profiler.
How can I reset those crazy Maximum Battery Charge and Current Battery Capacity to actual numbers?
I've removed the battery and done a SMC reset with no change.
I would look for a different app. It may be hard to find one for your system. Several I looked at were for newer system versions than you have. You can try the Edurance app which supposedly has options to increase battery life or use an increased speed of your mac. The downside is that this app is $20.00.  That's a lot to pay when many apps for battery life are free. They supposedly have a free trial. There was no minimum system given for this app so it may run on 10.4.
There is also a way to determine the number of cycles your battery has used. The instructions are given here. In this link, there are other links to determine the maximum cycles your battery has before it needs a battery replacement. Once you determine how many cycles your battery has you can go to one of the links and see if it includes your model.
