Healthy Batteries: Power Up Your RV


In our daily lives, we require some sort of batteries for various items around our home or work,  our RVs are no different. Some people like to only book campsites with power, but there are others who would choose a different route and have no power. Regardless of whether you do have power or not, you still need a healthy battery.

Many RV systems run on 12 volts. It is similar to your car, however, RV’s require a Deep Cycle Battery. These RV batteries are designed to be regularly deeply discharged.

Some people think that if you are plugging into power,that you do not need a battery. However, this is not the case and many RVs require a battery while plugged in. (ie. For slide motors, etc.)

Even more importantly, a battery is required while towing to operate the breakaway switch. In the event the RV were to become disconnected while towing, the only way to activate the brakes on the trailer is with a fully operational battery. Without the tow vehicle to slow the trailer, that break away switch is the ONLY SAFE WAY to bring your trailer to a full stop should this unfortaunte situation ever occur.


Your RV comes with a converter which includes a built in charger. This allows your RV battery to charge when plugged into shore power. Depending on the level of RV battery and how much has been discharged, depends on how many days it takes to recharge. There’s also a charge line in the towable RV is also a common way to charge the battery while driving; however, it can take a lot of time.

Solar power is also a great option as it provides constant charge throughout the day and there are several options when it comes to going this route. Ask our Carefree Parts and Service Specialists to help you choose the best option for you!

Generators also are very common and work well; however, some campgrounds have time restrictions as they can create noise.

You can also get an inverter which inverts your 12 volt battery to 110 volts (which is what you would have in your home) so that you can now use your outlets as you would if you were to plugged into power. This would allow you to use your microwave or coffee pot for example.

So enjoy a Carefree feeling, feel safe and keep your battery charged!  Be sure to keep the case clean, make sure the battery posts are corrosion-free, and top up fluid with distilled water. Stay proactive in battery maintenance and charging so you and your family can enjoy a great camping trip.
