Battery consumption with closed car
Has anyone had this problem and can tell me what to look for? The car after 4 days stopped consumes the battery completely?
Thanks in advance! |

It was mentioned on the G30 thread that a unlocked car for 2 days took 12 hours to charge on a charger, whereas a locked car took only 2 hours to recharge.
Electronics don't fully shut down. I now keep my car in the garage locked for a lesser battery drain. |

Do you have to leave it parked with the charger on so the battery doesn't drain?

Also short trips don't give it enough time to fully charge. |

why does an unlocked car drain the battery faster? what does a locked car turn off to conserve battery? When locked, security systems are activated. I never lock my car in the garage and never have had a battery issue, sometimes a week before driving.

I used a ODB MXII adapter and read the battery percentage when sitting locked for 2 days vs unlocked for 2 days. It seems it doesn't fully sleep (at least with G30s) when sitting unlocked. |

Probably the best test would be with an amp meter connected to pos and ground under the hood and see draw when unlocked vs. locked. Durring winter months I leave CTech lithium charger connected 24/7 with car unlocked, possible that some parasitic draw is good for cycling lithium battery or should I keep car locked all winter?
