Brand new battery dies quickly

Yup, furnace will take a battery out overnight with all the other items that require DC voltage. Changing to LED lighting 4 years ago really helped us cut down on consumption of our 12 volt reserves. Depending on your converter it could take sometime running the generator, even after running 2-3 hours you may be nowhere near fully charged, the poor battery gets drained even further down the next night. If your battery is not a true deep cycle it will certainly meet an early demise under this scenario.

If you camp off the power grid often you need to have at least a couple of fully charged batteries, a converter capable of delivering multi-phase charging, and some solar to help get the batteries further charged after running generator. Enough solar along with good weather conditions and the genny may not be needed for charging, being used primarily for powering heavy AC loads such as convection microwave and air conditioner. We use a pure sinewave inverter to power entertainment electronics or charge our portable devices.
