Low battery warning

[Morningken1]

Hi,I think I may have a faulty bms lead on my S60 2016 as it sometimes says start stop available almost immediately after starting a journey,then without using start stop,it will go to unavailable and I can travel 30 miles without it coming back at all.
Both batteries have been replaced and I have reset bms previously.
My question is,I have a lead coming from Ebay,does anyone know if the bolt on the inner wing to the chassis has a captive welded nut or does the inner wing lining need removing just to replace the lead ?

Thanks

Are you not asking this question in the wrong forum. This is S80/V70/XC70

After a couple of minutes the “low battery” warning pops up and the radio is switched off. She has a crash proof dog cage in the load area. It has a fan attachment powered from the load area 12v outlet to help ventilate the cage when the car is parked up with the tailgate open. But within a minute or two it is shut down by the car’s system. The only way to keep it running is to have the engine running. Sort of defeats the object of the exercise.
I am advised by others who have other makes of car that this is a common feature now. System is designed to progressively shut down various electricity consuming items to preserve the battery so that it will still start the car. That’s all well and good but in my opinion it kicks in far too early. I’ve never owned a car with this feature and never had any problems, other than when I stupidly left the parking lights on when parked up at work one day.

It sounds like your battery may be weak not being able to sustain the voltage for long. give it 48 hours on the charger first and see how that goes..

I just want to share being new to the forum I had volvo service centre in Launceston Tas, attach the trickle charger directly to the 12 volt battery under the spare in the back of my xc60. This connection has burned a small hole in the exterior of the battery and I am now told the charger should have been attached to the car charging points in the front LH side under the bonnet.
Can anyone confirm this please

the points under the bonnet are for convenience only, and go direct to the normal 12v battery

It is the standard 12volt car battery he clipped it to is it? You don't have a 48v hybrid battery under the spare wheel there do you? in which case it would have burned out his charger.
