I'm in Halfords at the moment getting a new battery as I've had another flat battery (the trickle charger failed) and I'm away this weekend.
But when they fitted the new battery the voltage is only showing 12.3v
The original battery was showing 11.99 and 99% health.
They suggested that the alternator may be on the way out.
So I just did a quick Google and there's talk of a smart alternator that only charges when needed?
I'm on my phone so I'll do a thorough search later. But thought I'd ask here quickly what voltage are you seeing in your batteries at idle? And is this smart alternator a thing?
Thanks in advance
