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.

Monitoring your RV battery’s state of charge is an important part of RV battery care & use maintenance. if you want to extend your RV battery life as long as possible, it is important to keep them fully charged whenever possible and recharge them as soon as possible when they have been discharged.

Get a battery voltage monitor from amazon.com, Walmart, or many RV dealers. Also available from eBay sellers.

120 Volt

Most of the RVs manufactured today are very stable with their voltage.  The problem is that many surges, spikes, and low voltage environments are caused by the the campground, or "shore power".

An inexpensive RV surge protector can be your best insurance against these voltage spikes and dips.  You can pick up an in-line 30A surge protector for around $75 and get a 50A in the $100 price range online or from Walmart.  The leading cause of microwave & electronics failure in an RV is electrical surge.

Even with a surge protector, it is also a good idea to take a voltmeter along with you that you can plug right into one of the outlets. Campground electricity varies depending on the demand placed on it. If everybody is running his or her air conditioner the voltage may drop below an acceptable level, and it would be wise to wait until it is restored back to normal. You can glance at the voltmeter every time you walk by it and save yourself untimely and costly repairs to your RV appliances. Voltage below 105 volts or above 135 volts can damage electronic equipment and appliances.

It seems there's always something else we need for our RVs but a surge protector and voltmeter are two inexpensive bits of insurance that will save you a bundle over the course of a few years.
