12v battery maintenance, issues, etc.

[UncleZen]

I went for the Yuasa YBX5012 in the end

Found the right Battery on the Yuasa Battery finder facility and found a local seller, which happened to be my local tyre shop anyway. £110 fitted (though I could have fitted it myself).

 

After changing the Battery, watch out for 'parking assist not functioning' warning. This will clear itself in a few hundred yards of driving.

@UncleZen I have a query for you. I have had an issue with my 2020 CHR as it did not start after 7 days of no use. I measured the voltage on the Battery and it was around the 8V region.

I went with some of the recomandation from the forum and got a Yuasa YBX5012 Battery but when I try to fit it, all is well expect the breather pipe. The breather pipe connection does not match the breather hole in the Battery. I noticed that the original battery had an adaptor which I pulled out and tried to put in the new battery but it does not work. Did you find any adaptor or new breather connection for this type of battery?

 

Many thanks.

@Ciprian88 well, I didn't fit it myself,  but I don't recall a breather pipe, sorry.

Breather pipe is on the 2 litre hybrid versions as the 12 volt Battery is located under the boot floor.

Managed to fix this with buying an breather adaptor from eBay, was not advertised for that specific type of Battery, but it does the job ok for the moment.

I think someone on the forum used windscreen washer pipe fittings from Halfords

Breather pipe difference in diameters can be easily dealt with small plastic pipe ends from any diy store near you, even anything left over in your tool box, pencil body, anything, it’s so easy diy job. 👍

Hi all,

Went away for a month and when I come back the car (2 litre- CHR) wouldn't start. When I press brake pedal and put on the ignition button, the headlight blinks a bit, show some parking brake lights and it becomes quite then. Seems Battery is discharged. Have called the recovery guy but any help will be greatly appreciated.

Many thanks

12 volt Battery is flat - might as well think about replacing it as its highly past its best now. 

You will have some warning lights appear once its running as you need to reinitialise some functions - its near the back of the owners manual.

Modern cars seems all have weak spots and particularly the 12v batteries. 
Leaving the car for over 2 weeks will almost guaranteed non starter on your return. Perhaps a solar panel, smart charger or disconnected negative terminal as preventative measure next time may help against flat Battery problems. You can recharge the Battery now for 10 hrs and if lucky you will be ok if not shortly after the Battery will require replacement.
