Which battery? :roll:
The big Li-ion battery does not have 'Self-Discharge'.
The Lead Acid battery under the hood does, and it's powering the Onstar cell phone and the key fob receiver constantly.
You could/should disconnect the Negative terminal from the under-hood battery. If you really are into it buy a small 'Battery Minder' to keep it topped up.
And, you should leave the Big Li-ion battery < 50% SOC. These batteries have better shelf life if not sitting around at 100% SOC.
And, if it is really hot or cold when you return, after reconnecting the L/A battery, plug the car in for a while before driving it to allow the battery's TMS to warm or cool the main battery as required.
Where you going? Hopefully to the tropics this time of year !!

Thank you for your reply. Yes, to the tropics, Central America in fact. I got a completely different answer from my Chevy dealer. They told me not to touch the 12-volt battery and to leave the car plugged in. I had an original Prius and always disconnected the battery if I was going to be gone any length of time. Anyone else want to weigh in?
I agree with NORTON, and the owner's manual says basically the same thing in the Vehicle Care section:
"Four Weeks to 12 Months
. Discharge the high voltage
battery until two or three bars
remain on the battery range
indicator (Battery symbol) on the
instrument cluster.
. Do not plug in the charge cord.
. Remove the black negative (−)
cable from the 12-volt battery
and attach a trickle charger to
the battery terminals or keep the
12-volt battery cables connected
and trickle charge from the
underhood remote positive (+)
and negative (−) terminals."

It's amazing what you can find if you RTFM!
I should do it someday.... :lol:
Let me guess, you spoke to a car salesman at the dealership !?!
You could go back and correct them, or not....
You know how to tell if a car salesman is lying?
