Battery problems in MacBook Pro 15"

I bought one of the first Intel based MacBook Pro that came out. This implied I got one of the batteries Apple have recalled. I found out some weird problems with the battery, and walked into the AppleStore in Palo Alto. After talking with support people there, they did some lookups and without asking any questions replaced the battery for me. About a week later, Apple officially started the recall program.

About two weeks ago, the (new) battery started to act weird again. After running on battery for about 5 minutes the computer shuts off. And I mean really shuts off. Not into suspend mode. I do have the Battery Update 1.2 installed.

Yesterday I went to Kullander & Kullander and talked about the problem. They thought it was another bad battery. I bought a new battery. I did the full charge, discharge cycle to calibrate the battery.

It seems the new battery solved the problem. So I have now encountered two bad batteries. Not fun. The best thing that now happens is that I either get the money back for the battery I bought, or that I get a second good battery. The old suspicious one I left at Kullander & Kullander to be sent in for service.
