I had to jump my 12v battery today - How do I maintain a healthy battery?

I did indeed take it into the dealer.(of course the battery was once again dead the morning of my service appointment). My 6 month service was due and I asked them to check the battery while it was at the dealership. Turns out the battery was indeed bad and it has been replaced. Thank you dealership

While I was there, I did ask them if there was a way to put the car in some sort of sleep mode which would keep any of the background processes from running and sadly, the answer was no. The only suggestion the master mechanic had was to store the key fobs some distance away from the car, but there was no real definition of far away was sufficient.

 

You can disable the key fob in order to reduce the car from wasting energy trying to detect the key. While holding the lock button, press the unlock button twice and release both button. Car will lock and red light will blink two times quickly then another two times quickly. This puts the key fob into "Sleep mode", not the car, but it should help if you keep the fob within sensing distance of the car.

I had my car at an airport parking lot for 6 days and no issues for me, but I didn't measure the 12 volt battery.
