RV Battery Voltage Monitor Helps Extend RV Battery Life

A lot of modern RVs are equipped with an RV battery voltage monitor. However, most older and many new RVs are not.

If your RV is one that doesn’t have an RV battery voltage monitor, you can add a simple volt meter that plugs into a 12v power socket for less that $10. These little volt meters don’t have all the bells and whistle features of the fancy installed monitors but, frankly, voltage tells you pretty much what you need to know about your batteries.

When plugged into power your RV’s converter works to keep your batteries charged. During charging you should expect so see around 14.3 volts. Once the batteries are charged the converter will reduce the voltage to around 13 volts.

When relying on your batteries for power it is important not to let the voltage drop below 12 volts.
