MacBook air boot only when I disconnect et reconnect the battery

Hi,

First, i apologise for my english. It's not my first langage ;)

To be practical that's a list of my problems et observations :

1. My mba boot only if i disconnect the battery et reconnect it. Or whitout battery.

2. With Apple diagnotics i have the error 4BAT/6/40000005:0x898f1790.

3. I can't stop the mba by pressing the power button for few seconds.

4. First i had a message "Check the battery" in the upper right side of the screen.

5. I replace it. And the problem is the same....

Did you ever had this kind of issue ?

Thanks !
