Nice, keep it going to see how long it can really run 
Is it one of the new models fresh out of the store? If you don't have absolutely nothing running, it might show something lke this
btw I saw you used Grab? cmd+shift+3 too complicated huh?

Let's say your true 100% charge battery life is 5 hours. 65336mAh divided by 4100mAh = 15.9x
So 5 hours x 15.9 = 79.5 hours of battery life on a single charge!!!...now wouldn't that be neat!!!
I'm guessing that the battery time indicator is probably programmed to display a maximum of 10.00 hours...thus not showing 79.5 hours.
But in reality...obviously there's some sort of "glitch" going on here.

No it's 8 months old and the battery has like 400 something load cycles. Every since I updated to Snow Leopard the battery signal has been acting weird.

If you're really concerned about this...try restarting your computer.
If that doesn't fix it try:
- shutting down your computer
- remove the battery
- wait 30-60 seconds
- install the battery
- restart
If that doesn't do it...you may have to try resetting the PMU:
Apple Portables: Resetting the System Management Controller (SMC)
I have had this happen to me before...sometimes you don't have to worry about it...and just let it run it's course. Sometimes after 10-15 minutes on battery power, it will fix itself.

Haha yeah that would be awesome! It has to be a glitch because it's not going down and I'm blasting music... But under the condition it says: Replace Now.

Thanks! The restarting didn't work but now I'm going to try the other thing.

By the way...463 load-cycles in 8 months is a lot!
Do you run your laptop on battery power quite a bit...something like going thru 2 full battery charges/day?
Just curious,

Well when I'm at home I plug it up even when the battery isn't dead. I never let it get below 40% so that could be the problem. Oh and I did the second thing and still no luck. I ordered a new battery that should come soon so I'll see if it get's better then. But I'm going to time this current one and see how long it lasts. My guess is like 3 hours maybe tops

3:39...is still decent battery life (IMHO). With a new battery + your old battery (as a back up) you will have plenty of "battery time" if you need it.
