XC70: Electrical - Battery/alternator issue

gerrymcdonough · Jan 1st, 2020, 12:43

Hi all,
I have a 2014 XC70 with D4 engine and stop/start functionality.

I have started to get the battery voltage low message, and upon checking it is reading 12.2 volts. So, yes it is low, 5 years old, probably needs a new one.
I also checked the alternator output which reads 15.2 volts. Well above the 14.6 recommended.

So, now I’m not sure if the alternator is causing the battery issue ?

Any advice appreciated
Thank you
Gerry

It'll have an AGM type battery so 15.2 volts isn't too high.
