What would you recommend for extended storing (3-4 months at a time) for a 2018 Subaru Outback. We have been told a battery quick disconnect is the best option but were warned this adder might void our mfg warranty. Thank you and great radio SHOW!
No, leave it connect and attach a quality battery maintainer. Since this is a short duration storage, probably the only other thing is add gas stabilizer to a full tank of fuel. If oil monitor is down to 20% or less, I would change it prior to storage.
