Battery problems
Twice now I have come out to find my 2018 GT3 with a flat dead battery. I have a tender installed but forgot to plug it in and it was dead after two weeks. I do have a Uniden R3 direct wired in the over head light terminal. I make sure to turn it off when I stop the car. Is this a typical experience?

Also, do you lock the car? I think that having the car locked can make a difference. Mine was good for at least 6 weeks with the car locked. The power ports had turned off and the car started, although the battery was weaker.

Haha, partially true, back in ninties mid 2000 yes I would agree, also my 993 use to drain a good size battery in two or three weeks, but modern Ferrari's can sit for a month, no issues.
It's better to have it on a maintianer on cars which aren't driven frequently for the long term health of the battery .
But a 991.2 GT3 should not drain a battery in such a short duration, OP have your car checked.

We have a cool product that can track this for you.... IT will show the drain on you battery and if you take off what is causing that drain it would show you.
But most the other suggestions the Rennlisters offered are on point. We deal with this subject alot being all we do is Lithium Batteries for Motorsports. The most often and highest parasitic cause drains nowadays are the Cameras, Radar Dectectors and the Chargers-USB and otherwise. Also when people add extra accessories to their cars they are often wired in wrong, and defeat the Cars built-in Battery management system that actually works very well to put most the cars to sleep with a low parasitic drain. The 991s are VERY good at putting the Car to sleep, and the batteries last very long. A 30Amp Hour Lithium Battery can last about 7 to 8 week in a stock GT3 without any accessories.... that is a for sure fact being I have that car and have been testing on it over a year and a half...
