best way to test house batteries ?
Hello Everyone… I have a 2003 Ford F-53 RV What’s the most accurate way to test house batteries using multimeter and hydrometer? Disconnect from shore power then keep few lights on inside the R...

First evaluate the system and post the battery age and the measured charging voltage.
I would start with a full charge. This would be charging at about 14.4 volts until amps drop to less than one amp per battery. This could take 2 to 8 hours.
After fully charging disconnect all batteries to separate. Let them sit 24 to 48 hours. Check resting voltage is 12.6+ and full charge on the hydrometer. Post the results.
If they hold a charge and are evenly matched just use them. If the capacity seems much lower than previous then it is probably time to get some new batteries. If the life seemed short it is a good time to evaluate your usage, charging and maintenance routine.
