Gum-Nut
2018 LTV Unity MB
So I learnt the lesson that the chassis battery needs a trickle charge if left for more than a couple weeks. I bought the Schumacher SP-400 solar panel and connected it to the ‘always on’ accessory plug below the cup holder tray.
We always turn off the master battery disconnect switch near the door when we’re back from a trip. Never thought the house batteries would drain when that switch is off, but in prep for another trip, turned on the fridge and about two hours later no power in the coach.
Thought we’d need to drive it to charge everything so started the engine; 30 seconds later power returned to the coach. So ran the generator for 30 minutes thinking that would be enough to charge the coach batteries, at least for the fridge. The next morning the step wouldn’t come down; internal LED lights worked; fridge was working. So ran the generator for 90 minutes.
The house batteries are now reading 11.8 volts. Testing them individually they read 5.92 and 5.88.
Checked the water in the coach batteries. They’re OK.
We park our 2018 Unity MB in a parking lot that’s not close enough to the house to run a shoreline to it.
We don’t have solar. How long should coach batteries hold a charge when the master switch is off?
