How to Check Your RV Battery
Checking your battery involves performing these two tests on a regular basis.
Preparation
Step1 Access the battery you wish to check.
Step2 Make sure you are checking the 12-volt DC battery and not something connected to the 120-volt AC power supply. Run checks on all batteries in your vehicle and record the results.
Step3 Remove battery caps.
The Specific Gravity Test
Step1 Perform a specific gravity battery test by inserting the syringe from the temperature-adjusted hydrometer and extracting the electrolyte (battery acid).
Step2 Read the gravity level. Record the result.
Step3 Return the electrolyte to the battery.
Step4 Repeat this procedure for each battery cell.
The Open-Circuit Voltage Test
Step1 Perform an open-circuit voltage test only if the battery has not been charged within the past 24 hours.
Step2 Remove negative battery cable.
Step3 Read the voltage across the negative and positive posts with a voltmeter. Record the result.
Step4 Reconnect the battery cable.
Step5 Close the hood or compartment storing the battery.
