Sorry, do you mean the battery that is located on the passenger side just underneath the windscreen? If so, that is the one I thought was the problem. When you say main battery, do you mean the one that actually drives the wheels!?On another forum, it has been suggested that problem is with the smaller backup battery, not the main battery. This was confirmed in a conversation with the service manager at my dealer.
The voltage measurements mentioned above only relate to the main battery.
The Cx60 has two 12v batteries, one small one as you mentioned and a normal AGM 12v battery.Sorry, do you mean the battery that is located on the passenger side just underneath the windscreen?

Thanks. Where is this AGM 12v located?The Cx60 has two 12v batteries, one small one as you mentioned and a normal AGM 12v battery.
The hybrid battery is 48v.
There are, as far as I’ve learned 3 batteries.Sorry, do you mean the battery that is located on the passenger side just underneath the windscreen? If so, that is the one I thought was the problem. When you say main battery, do you mean the one that actually drives the wheels!?
Thanks, I will go hunting before Tuesday, when it goes in.There are, as far as I’ve learned 3 batteries.
A 48v battery for driving the wheels
A 60Ah 12v battery, located under the cover in the engine compartment, near side in a RHD model
A 6.3Ah 12v backup battery located somewhere accessible from inside the car. This is the one that’s apparently the problem.
That’s why measuring the main 12v battery shows good voltage and charging up doesn’t fix the problem.
If you find out where it is, let me know please?Thanks, I will go hunting before Tuesday, when it goes in.
Strangely enough, I’ve now had 5 journeys without warning, using ash59 method.I will. Of course the warning hasn't appeared today.
Thanks - Edited my post.Folks, main battery which drive the wheels has 355V not 48. 48V batteries are usually in MHEV cars.
I'd be surprised if it was - typically batteries don't need a heatsink - Amplifier for the sound system perhaps...Steve. I found something under the drivers seat, towards the front. Black plastic cover. Holes in part of it with what looks like a heat sink inside. Two button looking objects on it. Thought I could remove the cover somehow, but didn't want to damage anything. Possibly have to lever off the buttons maybe. Could this be the elusive battery?
If it is about the message with the 12v battery, that the engine must be left on..., I reported the error to the service and they changed my 12v battery. Case solved.I'd be surprised if it was - typically batteries don't need a heatsink - Amplifier for the sound system perhaps...
It gets more baffling. Spoke to the technician he says there are only 2 batteries fitted. The large drive one, and a normal 12v. If there is another one, it beats me where it could be. Attachment below on what they carried out. Any further problems they will have it for a couple of days.On another forum, it has been suggested that problem is with the smaller backup battery, not the main battery.

Second 12v one is here, as shown by @ASH8It gets more baffling. Spoke to the technician he says there are only 2 batteries fitted. The large drive one, and a normal 12v.

When did you get the battery changed and has it cured the problem permanently?If it is about the message with the 12v battery, that the engine must be left on..., I reported the error to the service and they changed my 12v battery. Case solved.
I had my car in the dealers a few weeks ago. They didn't replace the battery, but reset various settings. No problems since.When did you get the battery changed and has it cured the problem permanently?
My CX60 is at the dealers for the second time with this problem....
Yes, I haven't had any errors and there were temperatures of -9 degrees C.When did you get the battery changed and has it cured the problem permanently?
