(due to work) Is it true that if the water level is kept filled than the battery can't freeze?
Not necessarily true. What does keep batteries from freezing is being fully charged. If you cannot plug the coach into at least a 15A service to power the inverter, then you have two other choices.
- Check the water level of each cell and top off with distilled water. Then plug the coach in for at least 24 hours prior to storage to fully charge the batteries. Once you are parked, remove the NEGATIVE cable from each battery set (house and chassis) to isolate the batteries from parasitic loads that will drain the batteries. If possible, go to the coach every 8-10 weeks, connect the negative cables and run the generator for 2-4 hours to recharge the batteries. Plug in a heater or run the AC heat pumps if you have them to provide a load for the generator.
- Or, remove the batteries and put them in a dry/ventilated place where you can connect a trickle charger every few weeks to keep them charged.
The life of your batteries is decreased each time they are run down. Keeping the charged is imperative.
