Coach Battery Replacement Help

The chassis batteries should be your typical starter battery, not deep cycle. On my inverter/converter there is a set up process where you tell the unit what type of battery is installed for the house so that it handles it properly. Deep cycle is preferred for the house. You need to make sure that your inverter is a 3 stage type unit so it doesn't boil out the battery again (or you need to make sure that the water is topped off on a regular basis)
