Ford Focus Battery Alarm Defective

I had a similar issue last year on my Focus. Was the battery signal acting strangely? Check the battery status with a system diagnosis to rule out other issues. The error stored in the error memory can give you a clue.

Did you perform the system diagnosis yourself, or did a workshop do it? What tools were used? Was the battery problem visually noticeable, or only detectable via diagnostics? Trying to get a clearer picture before replacing the battery.

Given the alarm system's involvement, I wouldn't try fixing it yourself. My battery issue wasn't visually noticeable, just error messages. I recommend a workshop for an accurate diagnosis.

The workshop confirmed a discharged battery due to age. Repair cost 330€. Thanks for confirming my suspicions and pointing me in the right direction!
