What to do,winter

For those of you that have a battery disconnect. This is our first camper with one. Do you turn off the 12 volt and leave the battery on the camper then charge in spring. Also for those with the BM pro tablet. Do you disconnect the tablet and bring it in for the winter. Trying to figure out what to do with tablet

The factory 12 volt disconnect Does Not remove all items from the battery. The Propane Carbon Monoxide sensor is still live. It alone will discharge your battery in a couple weeks
For winter storage either provide some sort of charger be it a trickle charger or a solar panel setup to allow snow to slide off.
Just remove the battery or batteries and store in a garage. They will discharge slightly over the winter but not much. They will do better in an above freezing location.
As for the tablet. It's going to try to communicate with the BMpro node constantly until the battary in the tablet dies

Batteries in it are like any consumer tablet device.
They are a lithium based battery.
Lithium does not like to be charged below freezing.
It is best to bring it in and charge it with a standard phone tablet charger in your home.

For our Alante, I plug the RV into 20a 120 volt with extension cord. Leaving the battery disconnect on. So, the house batteries are charged. I also take all batteries out of remotes. Anything that has rechargeable batteries that are not removed, I take them into the house. Every month, I take it out for a 1 hour minimum drive with the generator running. I start it and let it run for 20-30 minutes along with the generator two weeks after driving it. Batteries, like humans, need exercise.
This is just what I do.

Where do you store your camper? How cold does it get where you are at? Do you have a lead acid battery or lithium?

On many of the newer campers Jayco's BmPro/JayCommand along with the CO/gas detector bypass the battery disconnect, which will drain a battery in a few weeks. Personally, I would physically disconnect the battery. If your in a really cold location, pull the battery and keep it in a warm environment (mostly above freezing). A charged battery will not freeze.

If the camper is at home and can be plugged in, leave the battery in the camper let the on board converter keep it charged all winter. If you have a maintenance lead acid battery (most common), make sure the fluid levels are topped off, ONLY USE Distilled water.

I pull my battery, and put it in my shop. I'll put it on the trickle charger maybe twice during the winter. The voltage may drop 0.1 volts over the course of the winter.

As for the tablet, I suspect the best thing you can do is pull it and charge it in the house over the winter. Lots of people seem to have dead battery issues with these tablets in the spring.
