+1. The battery voltage is a variable value depending on the load. If there is zero load, the 90% value is a fair estimate. If the battery is under load (e.g. the fridge is running on battery), then you might be closer to 100%. You can't really tell the battery State of Charge (SOC) without taking it out of the circuit and letting it rest for a bit. That's typically not practical, so we watch the voltage and "guess" a little bit.]]> Thu, 13 Sep 2018 09:17:02 +0000 http://www.rpod-owners.com/forum_posts.asp?TID=12184&PID=114983#114983 testing battery after powering refrigerator : I do that all the time.

I do that all the time. Appears battery is charging from TV and 12.62 is a good value. The fridge is using battery charge and TV is replenishing.]]> Wed, 12 Sep 2018 15:46:54 +0000 http://www.rpod-owners.com/forum_posts.asp?TID=12184&PID=114962#114962 testing battery after powering refrigerator : Hello.I have a 6 cylinder Jeep... http://www.rpod-owners.com/forum_posts.asp?TID=12184&PID=114959#114959 Author: Happy Tripping

Hello.

I have a 6 cylinder Jeep Cherokee and propane doesn't work for the refrigerator so I just travelled 2 1/2 hours  running the refer off the battery. After resting, my multimeter says the battery has 12.62 V, which is apparently 90% of the apparent fully charged level of 12.73 V. I say 'apparent' because I don't know nuthin' about this whole subject and I did not test the battery's voltage before I took it on the drive.

The bottom line, is it ok for me to run the refer on battery on 2 1/2 hour long trips or am I incompletely charging the battery and allowing it to run down because the Jeep's electrical system isn't up to the job??

Or, of course, did I screw the whole evaluation up and now have to do it over right?

When not in use, I keep the battery on a trickle charger and the water levels look ok.
