Check for a black panel (usually on passenger side wall near RV entrance door) as shown in picture below. Press the ‘BAT‘ button and the LED display will show whether the RV battery is 1/3rd, 2/3rd or completely charged.
If RV battery is not fully charged then just turn the generator or the RV engine on for few minutes and this should charge the battery fully.
Note – If despite charging the RV battery does not stay charged for long then it is likely that the RV battery is weak and need to be replaced, please report this to the RV owner so it can be replaced before the next rental trip.
