Battery life abysmal since upgrading to leopard

I have recently upgraded to leopard on my first gen 2.16 ghz Core Duo MBP. I noticed that I had significantly reduced battery life since this upgrade (from about 2-3 hours down to about 30-40 minutes), so I decided to check out the battery status with coconutbattery. I've been tracking the maximum capacity of the battery the last two days, and it keeps jumping up and down. on 11/07 it was at 37% (2089 mAh), so I decided to recalibrate the battery, thinking it may help. Just before recalibration, it read that I had a max capacity of 34% (1907 mAh). I let the battery drain overnight and charge this morning. I then checked out the max capacity, and it was at 28% (1542 mAh). About 10 minutes later, the max capacity jumped back up to 35% (1931 mAh). It seems really strange that this keeps occurring.

Below I have posted the contents of the battery section of Apple system profiler. I know I have a fair amount of battery cycles on this, but I don't understand why the battery life has gone down so significantly. I don't hear any fans whirring/drives spinning/etc. that would indicate a major drain of power. Is this something that could possibly be addressed with a 10.5.1 update, or would it be worth calling applecare to see if they'll replace my battery?

Addendum: When I open my computer after sleep, the battery can read as high as 10 hours for a charge... and then it scales back to about 1h30.

in case any new people are experiencing this issue, here's an update.

fyi, i finally got around to calling apple, & getting a new battery, & the problem is solved (knock on wood).

http://www.apple.com/support/macbook_macbookpro/batteryupdate/

1 of the symptoms listed is: "Battery exhibits low charge capacity/runtime when using a fully charged battery with a battery cycle count (as shown in System Profiler) of less than 300."

Call them up, & they'll sort it out. my new battery even arrived in less than 24 hours.

UPDATE: Apple Replaced My Battery!

I too have the first generation MBP 2.16Ghz, and the original battery from August 2006. While on a business trip, my battery capacity read 0%. I open Coconut Battery, 0% max capacity. Interesting I thought since I was consistently getting 60%, then 38% before leaving on my trip. After letting it sit overnight plugged in, I was back up to 42%. I did a drain, it went to sleep, recharged, and I was holding at 38% again.

I figured it was worth a shot to call Applecare since I was only getting maybe 1 hour out of the battery. They stated that since I was under 300 charge cycles and that it definitely was underperforming, that it would be covered under Applecare. They next-day air me the battery, and I'm using it now.

Key difference? It's NOT a Sony Battery, here are my new specs. I suggest you all call Apple and get your batteries replaced! I'm very satisfied with their customer service, and the tech was fantastic.
