Inspiron wear level jumped 60% in just a few weeks...what the heck?

I have a Dell Inspiron 6400 laptop and it was running just fine. Just 2 weeks ago, my wear level was at approx 10% and I could get around 2 hrs battery life. Now, my battery life drops to about 40 mins. I checked the wear level and it says my battery is at 73% wear. What is happening? How can the battery just die almost overnight like this? I dont use my battery much and only do a full discharge occasionally. Ive already tried running my computer with the BIOS loaded and fully draining the battery, then recharging it, but my wear level is still at 73%. It seems strange to me that a perfectly functioning battery would suddenly decay so quickly in such a short period of time. What do you guys think is going on?

I heard something about putting the battery in the freezer, then charging it up again to rejuvenate it. Any other tips what I can try out first before buying a new battery?

How old is your battery?

My battery is a little over a year old, so a few months out of warranty. Wow, I did some searching and apparently I am not the only one with this issue. MANY OTHER Dell users have had their battery mysteriously crap out just a few months after the warranty ended. I am really starting to suspect that Dell includes circuitry in our batteries which PREVENT it from being charged (and appearing more dead than it actually is), while the cells are actually still quite alive, hence forcing us to buy new batteries. Here is a page which outlines my belief:

..Now I just need a method to try to bypass/hack the circuitry.

i heard you can leave it in the freezer for some time and it will help revive the battery.
