Hi John, I just check smaller battery, it's resting at 7V and 14.5V when car idling. I've also attached a photo of warning light that come on after driving for 30 mins

Hi John, Thanks, I checked the main battery last night it sat at 12.5V car off and 14.7V car idling, you still think it'd worth charging up before replacing it? I will look at better charger, is there anything specific I need to do prior apart from negative clamp to chassis of car? Thanks! Jack

Hi there, I have a 2015 XF 2.2D (2008-2015 version). Had the car for 4 years and the stop start function has never worked. I noticed if I drive for roughly 30 mins + the stop start light will come up on dash. Id like to start with charging both main and aux battery, is there any specific procedure to follow when doing so? I have a basic battery charger. It says it's a smart charge and covers AGM, cost around £25 do you think this is suitable? What V should I expected from both batteries with engine off and on? Any other suggestions would be great. Thanks so much in advance for anyone's help!
