I haven’t had to replace battery, everything seems fine now.

Also, there are some amazing YouTube tutorials on how to remove and check the alternator out of Skoda’s, but the amount of stuff to remove makes me miss my Old Datsun - three bolts to take it off!

As for why it was flat, I may have left the ignition on on the weekend. At home I don’t tend to lock the car, and I had been checking the windows seals, but not sure. I will keep an eye on it. It was charging on my last car trip from the alternator (14.something volts) so fingers crossed. Thanks for the tip on the start stop! I was ready to book it in and thinking about which kidney I was going to sell.

Thanks for the tip, yes it is start-stop, I haven't owned one of those before and hadn't thought about that. Do you have an idea at what battery voltage should it kick in to charging mode? I'll start on some googling, but I hope I haven't stuffed up by charging the battery with an older style of charger (I removed terminals to charge).

The link fuse (is that the right name, as per picture below?), looks ok, but if it blew, might not be obvious? A guess a continuity check from top to bottom with the multimeter might rule this out. Also, would putting the multimeter on the positive terminal of the alternator and the other end on the car body (while running) would also be a check for the alternator charging, though need to be careful obviously?

I had a flat battery, and charged overnight. After charging, voltage read 12.6ish on the multimeter, and started fine. After starting, the voltage measured at the battery did not increased to 13 or so (what I would expect if the alternator was charging). I've driven it a couple of times, and it looks like the battery is slowly losing charge, but I have no warning lights now (The engine light was previously on for low battery charge, but I cleared it with a friends OBD tool after charging the battery). I've also checked fuses under the bonnet, and they all look fine. Is there anything else to check before sending in for an alternator replacement? ps - I'm still puzzled why I wouldn't get a warning light for what seem like a basic problem (my 1971 Datsun would have let me know!).
