Partly out of curiosity but a practical question too - roughly how long can a CX-3 be left parked before the battery runs itself flat ?

Say with a healthy normally charged battery and say the NAV+ gizmo electrics pack parked normally with all lights etc off ignition off and vehicle locked?

In practice how long is safe and how long runs it flat?

What is the current condition/capacity of the battery?
What is the parasitic average current with everything turned off?

In my previous model CX-3 (2018) the parasitic average current was around 55mA and the battery capacity I believe was 60Ah (when new).
60Ah/55mA = 45 days before the battery is completely depleted.

Remember that you need enough electricity left in the battery to start the car...

Thanks and the 55mA figure is also good to know.

I always run mine for 30 minutes every two weeks if I'm not using it. I have left it for 4 weeks and it has been fine. It all depends on the condition of your battery.

I meant to add that I always carry a jump start pack, just in case I ever have a problem. You have to remember to keep it charge though.
