Hi. I just got my new to me 2022 911 C2S by transport yesterday.
The doors are pretty tight after 18 months, which surprises me, and I'm assuming it was never completely closed after being put into the trailer.
When it got here yesterday, 2 days later, it wouldn't start.
My son has a portable jumper and jumped it from the wheelwell, and drove it around for a while to try to charge the battery.
The car does start now, but how can I tell without anything sophisticated (since I'm not) that it's holding enough of a charge and wasn't damaged?
I read online that if you put it in ACC mode, the battery voltage should read >12.6 on the right dash gauge.
It is, but I'm also getting a warning after turning the car off not to use the PCM unless the batter is fully charged.
Is that just a generic warning? Or do I have an issue?
Thanks for any recommendations.

 

AGM battery? Put it on a CTEK battery maintainer over night and see if it goes through all the stages. If it does , the battery is likely ok.

 

Thanks for the reply.
I have rear-wheel steering, so it might be a Li battery.
I'll have to check.
I do have a Noco Genius 5 which has a Li setting, but I don't know if it's compatible.

 

The PCM warning is generic. Put it on a Li maintainer and see what happens. Likely all good since you got it started in the first place.
