MacBook does not recognize battery

I have a MacBook, the Black one, about eleven months and since last November it started to act a little weird. Here it’s what's going on: the laptop does not recognize the battery and then the system goes to sleep mode, even if I am using some heavy programs at the same time or just looking the desktop.

The first time (last November) I didn’t care very much, and then happened about two more times in the same month, but I thought it was OK. However January was little more often, and I was worry. Nevertheless now it’s the worst month, even worse the February. Each 5 minutes the laptop goes to sleep mode, it’s driving me crazy.

Ten days ago I was using the laptop, and then the system went to sleep mode. So I plugged the AC adapter and the, the battery status showed “No batteries available” and a X on the icon.

See MacBook, MacBook Pro- Battery not recognized or "X" icon appears on menu bar.

If you are able to operate near an AC outlet, then you should connect the AC adaptor. Do not operate using the battery if you don't have to. All usage of the battery will eventually cause the battery's life to shorten. This is normal since the batteries do not have unlimited life.

Not much more to tell you because you've not provided any stats on the battery's actual condition, cycle count, etc. You can read the following for more about batteries:
