12v battery low please connect to charger

[lemans]

Mine died too after 9 days unused over Christmas, I had to do the manual procedure to get to the battery and jump start the car.
I has come up very occasionally when I get in the car with a warning that an accessory is drawing too much power, the only thing I had plugged in was a USB stick of music now removed.

Anyway I did a 470 mile round trip last week and thought that would give plenty of time to fully charge the 12V battery but the display showed 14 to 14.2 volts for the whole drive so if a fully charged battery shows around 13.4V mine wasn't charged even after 10 hours driving.

any update on this?

No, I haven't had a period not using the car that long since.
I have bought a trickle charger just in case.

does your car still run at the 14-14.2 volts?

I have my Taycan for 2 years now and never had a 12 v battery warning. Car is a dream. No problems at all.

Same. 2022 with 20kmi and mostly a daily driver. Sometimes in the garage for a 7-10 days while on business or vacation. Sometimes plugged in, sometimes not. Never had any kind of 12v battery issue.

There was an unconfirmed rumour on here that the WRW1 (I think) update to comms systems was supposed to fix. That one got bundles with a battery change and sent OTA recently. My OPC has no information whatsoever. All they can offer is another opportunity to surrender my car for a couple of days to test. I’ve not left it parked long enough to know whether it is better or not.

I had the 12v get low on me once. It was after the car had sat for several days and the garage was likely colder than usual as it was during a cold spell. It said please connect to charging equipment, etc. If you left the car sitting it would turn itself off.

I've since purchased a trickle charger and I haven't seen the message again. The car still seems to run at 14-14.2 though.

On short journeys definitely but I haven't looked on the longer one I did recently, sorry.

That is the other thing I wonder. Typically the trips are quite short. My office is less than 2 miles from the house.. I guess I really haven't had a longer trip since manually maintaining the 12v with the trickle charger.
