1. How to Check Your Motorhome
Battery

2. Since the entire purpose of a motorhome or RV is to allow
you to have all of the conveniences of home no matter
where you go, it is particularly important to understand the
functions of the batteries that power it.
There are 3 ways to check an RV battery:
Dashboard Monitor
Though this is the least accurate method, it’s very simple
and gives you a rough idea of whether the battery needs
charging. Just make sure the RV isn’t plugged into shore
power, turn on a couple of lights, and check the reading.

3. Test the Voltage
For this, you’ll need a voltmeter and you’ll need to know
the voltage of your battery (6 volt or 12 volt). Select DC
voltage on the voltmeter, touch its red cord to the battery’s
positive terminal and the black cord to the negative. Less
than 6.35 volts (for a 6 volt battery) or 12.5 volts (for a 12
volt battery) is an indication that the battery needs
charging.
Check the Battery’s Specific Gravity

4. This requires a hydrometer as well as protective gear.
Remove the battery’s vent caps (if it is not sealed), check
each cell’s electrolyte levels, fill and drain the hydrometer
twice from each cell, then take readings. If the average of
all cells is below 1.277, the battery needs to be charged. If
there is a difference of at least .50 between the highest and
lowest cell readings, you may need to replace it.
