Macbook Battery trouble....

It happens to my mac the exact same thing on 11-1-2011 my battery have 3 led's when i press the button on it but the Mac doesn't seems to find the battery.
I allready tried something:
Reset SMC, install battery update 1.2 and 1.4.
but nothing happen.
I did went to a Apple Store and they said is that the batery life has passed out but they didn't convince me. (the boy that talks with me said that the batery has a maximum of 300 cycles of charging (what did a ear well??? less than a year of charging??? i think mine have at least 1000 cycles of charging and it was prety good)). I asked to try other batery but he said that they dont have one for teste only if a bought one :S.
Apreciate any help thanks
