Hello Everyone
I have recently been getting the SOS warning system light on the dashboard. My lead acid battery is original ( now 6 plus years old) I wondered if this might be the cause ? any views. Also as this battery does not crank the car to start are there any other indications of when this might need to be replaced before the inevitable "oh hell "day when nothing happens when you try to start up the car and you are stuck.

You just need to check the battery voltage using a voltmeter or tester (cheap ones available on Amazon if you don't have one)

You can buy voltmeters that plug into the cigarette lighter socket giving a constant voltage display . But they can be a bit of a worry meter. I used one on my 2021 car before it was 3 years and even then it often read below 12v if the car had been unused for a few days But it still always powered up the car.
We dont seem to get as many complaints about flat 12v batteries since Honda changed battery brand to Panasonic/Yuasa in about 2023.
The battery is comparatively small. 6 years old may be pushing your luck.
