New Laptop Battery

Received a new battery for my Ti Book today. So far, it is charged. I am supposed to wait 12 hours before going off line power then run it down until my laptop suspends. (This to try and calibrate the microprocessor in the battery) That part isn't a problem. What concerns me is that as with the old battery the charge went to ~75-80% and then jumped to 100% charged. The reverse was also happening with the old battery only it was jumping from ~35-40% to 0% Hopefully this will not be the case with the new battery. Although 2.5 years and still over an hour of full power use isn't too bad. We will see. If I continue to see strange behavior I will go for a PMU reset. Then off to the genius bar if I can show the problem with more than one battery maybe I will get somewhere without having to let them have my laptop for testing for a minimum of three days. Repair is one thing, but testing where I know that what they said they will do is watch it charge and discharge a number of times is just silly. Particularly when I can show logs of the charge discharge cycle.
