Hello,
I am going to be leaving my 2017 Volt outside for 3 summer months in Miami (Daytime highs mid 90's, night time lows mid 80's.....). I have searched the forum posts on this subject, but they are a little confusing. For one, my owners manual has no information on long term storage, it only says to leave car plugged in when not using so battery is maintained at correct temperature. Many posts mention information that is in the owners manual...so I am out of luck.

My question is, did they change the software/hardware in the car so it is now correct to leave it plugged in? What is the proper way to leave it when it is hot outside? At this point I am thinking of leaving the battery at half charge and attaching a trickle charger to the battery terminals under the hood (which I assume is the other 12V system).

Thank you for any good answers....

This is from page 257 of my 2017 Owners Manual:

Vehicle Storage - 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 high voltage battery charge cord.
. Remove the black negative (−) cable from the 12-volt battery. 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. See Jump Starting - North America for the location of these terminals.

I would also put some kind of car cover on it.
