Macbook Pro battery draining uncommonly fast

Recently, over the past weekend it seems like, my battery power has started draining uncommonly fast. I have a 2010 mid year Macbook Pro, and I've taken excellent care to prolong the battery life. Previously, it was lasting at 7 hours without charge, but these past two days it can barely go 2. The activity monitor shows no heavy applications, but it says finder needs 99.7% of my CPU to run. Is this normal? Is this what is causing my battery drain? What do I do?

MacBook Pro, Mac OS X (10.6.1)

I think I just solved my issue- I let the battery drain and then didn't charge it for about 12 hours or so. Just turned it on and the activity monitor is showing normal levels, haven't tested out the battery life yet. Hope this helped!

The Finder needing that much CPU is not normal and it is very likely it was causing the unusual drain. The Finder desktop just sitting there, should not use up an entire modern CPU. Chances are it got stuck on something...a network connection, managing a window, maybe generating a preview (although usually that's QuickLook that gets hung up).

If you see unusual Finder CPU usage happen again, ask here again so it can be troubleshooted.
