Mr Anxiety will be leaving his Camry at the Airport for 9 days and is concerned about it not starting when he gets back. The resting battery was 11.5volts yesterday morning after a cold Wisconsin night.. I charged it up which only took 30 minutes, and it was then 12.7volts. Disconnected the charger and left it overnight last night... 12.45 volts this morning... Just used my clamp meter to test the resting discharge and it is showing 0.4amps which I think is a lot ? Is it a lot ? If I slip the negative lead off at the airport, will that lose my transmission 'learned' settings ? ps Never a problem starting and I often leave it for 3 days...
