I may be away for 65 to 80 days this winter.
I will store one car in my garage and use trickle charging to maintain battery.
Our other car (2005 Mazda 3) I hope to store inside in a rented parking spot. I really doubt I will have access to a plug to put a trickle charger on it.
Should I disconnect the negative post of the battery???
I will not be away longer than 80 days.
