Update to my problem. I gote two new batterys for my MBP and did a test! re-installed OS X 6 Installed one of the new batterys. The battery lasted over 3 hours Alowed OS X 10.6.0 to update 10.6.8 Over the next 4 weeks I run the MBP on the battery 3 times a week never letting it drop below 20min (As the battery was less then a month old did not cycle it). By the end of the 3rd week the battery was lasting less the 40min's Re-plased the battery with the other new one. It's now been over 3 months and the battery is still OK This would suggest that there is a update between 10.6.0 and 10.6.8. that changes the farmware in the battery that afects the way is charges or discharges or re-ports charge. My suggestion is if you are updating to any update in the 10.6.n range then remove the battery while doing the update.
