Advice on Long Term Storage

[Mdmorrissey]

I need some advice on how to properly store my 2019 JLU when I am out of town for several months at a time, and in particular, how it relates to the batteries. I live in a condo complex and don't have access to electricity, so a battery tender is not an option. I have tried disconnecting the negative from the main battery which works for that battery, but the secondary battery still drains dead and I have to have it replaced. First time this happened I took it to the dealership and they replaced the secondary battery, but seeing how I am nearing the end of my factory warranty, that is not going to be a long term solution. Hope that somebody here has a good solution. Thanks in advance.

if truly long term, pull batteries and put inside on tender.

I like to keep gas tanks full so there is no condensate.
