I hear less-knowledgeable RV'ers use the terms "inverter" and "charger" interchangeably all the time. Your neighbor is probably in that category. I would probably not take and stock market tips from him or her either.

Thanks Gloria
Is it possible he said 11.9? Not 9?

11.9 is more reasonable.

Thank-you thank you. I finally understand how the inverter works. You all are great. No, scottinnj, he definitely said 9.

50%?

(Tongue in Cheek - to illustrate a point):

Wait - I can discharge my battery 50% before damaging it - isn't that SIX (6) volts???

I am confused!

Alarm for low battery?

Is there an device (iOS would be nice if away from rhe AS) to alert us when battery levels get below the half way point? Suggested products? Thanks!

Hi, you know you're replying to a 2 1/2 year old thread?
You should start a new thread to avoid confusion.

A fully charged 12 volt battery measures about 12.6v. At about 12.1v it is half discharged. You can buy a small dc voltmeter on Amazon that you connect to the battery or any place you have a 12 volt light or receptacle for less than $20. Just make sure you check the voltage when the batteries arenít being used to power much of anything.

Here is a table showing the voltage versus the percent charged and an $8.99 voltmeter you can order from Amazon.

On an Interstate, you don't need to buy a separate meter. The battery voltage for both the house and the chassis batteries is available with a button push on the tank monitor panel
