So 992 GT3 sitting on the lift for a month with charger specific to Li battery from Porsche plugged in in to foot well, and as I described before , in order to avoid battery lock out before you plug in charger (foot well or directly to battery terminals ) ignition must be on . Today I get inside to do some work on the shifter , do not unplug charger or turn ignition on . Close car and in 2 hours car was not charging. I turn ignition on ands plug in again and it’s working fine .
