All of our neighbours in Florida, who leave a vehicle there from year to year, disconnect the battery before departing for the season. The vehicle's onboard computer continuously draws current and can drain the battery. How long can a vehicle be left wth the battery still connected?

With a new battery maybe two months.

That's about how long we'll be away. Better disconnect. Thanks

And if you have a 2017 Camaro or Corvette, it's 7 days. Had multiple customers experience the same issue. I dealt with the same customer from Mississippi 3 separate times during a 2 month span. Never a good idea to leave your vehicle in the hot sun for too long if you live in the South, even if for only a handful of months.

Maybe try a dash solar charger?

My parents have a 2021 Sierra and 2015 Yukon Denali. They’ve learned the hard way that the battery needs to be disconnected when they go to FLA for the winter as the Yukon has killed 2 new batteries 2 years in a row despite me starting the vehicle up every couple of weeks.

Consider a trickle charger, or a solar charger as Audiophile mentioned.

We're only going away for a few weeks. I'll just disconnect.

If the battery drains down, use a jump box to get it started, let it run for a while, and the battery will charge back up.
