I think this battery is dead but try to reset SMC and then check battery status again when it's same then it's BAD
Resetting the System Management Controller (SMC)
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
- Shut down the computer.
- Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
- On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
- Release all the keys and the power button at the same time.
- Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Thanks for the replies!
I've actually tried all of these suggestions a few times and no luck. I received the new battery yesterday and it wouldn't charge or run on it. When I put in my old battery (dead one) the magsafe light turns to orange, but the battery is dead. I think the issue is bigger then just the battery, I should also mention that I dropped my macbook a few months ago and also triggered the red light in the headphone jack. tried the toothpick/paperclip method but no luck. Think I'll just take it in to get looked at.
also, when i hold option and click the battery icon, nothing happens.
Thanks for the suggestions! any other suggestions are welcomed!

I would return the "new" battery as defective. You were probably sent one that had been laying on the shelf since the start of the century. Lithium-Ion batteries, especially those used in the older generation Macs prior to the unibodies, have an unstable chemical composition. Their capacity degrades thru time, whether they are used or not. After 3-4 years they are a shadow of the original specs. Closely inspect the label and see if there is any sort of date; almost certain it will be ages ago.
After the brouhaha caused by the not-user-replaceable stance that Apple took with the unibodies, the specific kind of Li-Ion batteries used was much improved, resulting in higher power capacities and somewhat improved longevity. Unfortunately, neither Apple nor any other manufacturer ever upgrades the engineering on older models, since the business model is for you to buy the new stuff.

I talked to a mac tech at a local repair place just now and he said the exact same thing. He said if that doesnt work then he thinks its the dc inboard. I just got a replacement being sent to me. fingers crossed. We'll see what happens.
Thanks again guys!

I was thinking about what you said, but the new battery lights up and is charged. Wouldn't that discredit the dead battery theory? thats why I was thinking the problem was internal.
let me know what you think.

The fact that the on-board battery controller circuitry reports a 0 mAh capacity, as displayed by the profiler, makes me think that the battery pack is unusable. Try to get ahold of an alternate battery to test and compare.
