Crappy stock batteries or something wrong?

[Bob Denman]

It always takes more power to start them; than it does to run them...

The Inverter is a Modified Sine Wave. Would a Full Sine Wave ainverter help solve my problems?

[Bob Denman]

Unfortunately: it wouldn't...
You just need more power.

The Harris batteries have a date on them and after mine went dead I called them and asked about what the warranty is, and was told they warranty them for 1 year from when they were made so my dead batteries were dated May 2017 and June 2017 and I bought my 2018 Compass in September of 2018 so the batteries were already out of warranty.
The dealer came good for replacement cost of two Napa group 24 Deep cycle batteries.

Glad to hear that he stepped up to the plate for you.

Are you sure about the radio running off the chassis battery? Mine, and others I have seen run off the house batteries.
Another thing that will run the house batteries down as well as propane is the Girard demand water heater. Even with the store/use switch in store, the Wh will run from time to time, if it gets too cold. It is a feature to keep it from freezing.
The only way to stop it is to shut it off in the outside panel.
Running batteries dead isn't great but it won't ruin them immediately. Mine have been run clear down twice and they are still fine after three years.

However, bad house batteries should not draw down your chassis battery. You may have either a bad chassis battery or for some reason it is not receiving a charge from your system.

Hi,

For the battery replacement, what type/ group size did you replace the 2/6 volt house batteries with the DURACELL?

Thanks
