Should I Disconnect My RV Battery When Plugged In? 

If you do own an RV, you must have been curious about this question at least once- “Should I Disconnect My Rv Battery When Plugged In?”

Well, to get an answer to this question, you might need to have some basic knowledge regarding the power input and output of RVs. In short, the answer would be a yes, depending on the situation. 

However, that is not all there is to this matter. So are you caught in the loop yet? Well, what are you waiting for? Scroll down below and keep reading! You will get all your answers soon!

Do I Need A Battery If My Rv Is Plugged In?

Connecting your RV to the house is an option you are entitled to only when not constricted to morality issues like saving electricity. However, did you ever think of not using a battery while the RV plugged on? 

Consider yourself lucky if you haven’t and dumb if you did and even tried it out. The battery on the RV is connected to a converter. Let’s say that this converter has a rating of 120V (most RVs are rated at 120V). If your house doesn’t provide 120V electricity, your RV will refuse to work at all!

The battery comes together with a converter whose sole task is to convert the raw electricity provided by the house into a stable voltage that the RV can handle. The battery stores this energy and gives it to the RV through its circuits. 

While you will always require a battery in the RV, we advise that you check on the battery electrolyte level regularly, at least once every month. This is because too much charge might cause the battery to get damaged.  

What Does The Battery Disconnect Do On An Rv? 

All electronic devices require electricity as a source of energy. They need to convert the electric power to mechanical energy and do work. The RV is not an exception to this rule.

The battery disconnect switch stops the battery from providing any electric energy to the RV. While the RV will not work at all, when the battery has been disconnected, it can protect the vehicle from many external factors like theft and electrical fires.

Additionally, it also has other benefits of disconnecting the battery when you are not using the RV. This will increase the battery’s life expectancy in the long run since we are not keeping the battery connected constantly. 

Additionally, it is also a necessary safety measure when carrying out maintenance. By turning off the battery, we are decreasing the probability of getting shocked while working with live wires that could otherwise kill even the deadliest of animals. 

Where Is My Battery Disconnect With On My Rv?

If you want to disconnect the battery from the RV, the best way to do so is to switch the disconnect button off. It is much more convenient and accessible than removing the battery manually.

As the name of the switch suggests, it is meant to cut off the circuit in the power supply so that no energy is provided to the vehicle. If you are looking for the battery disconnect switch, look no further since it is always located near you

All you need to do is open the battery compartment of the RV where the battery is located.

While the disconnecting switch can be anywhere inside the battery compartment, it is typically located precisely by the maintenance bay.  The chances of the switch being located anywhere else are pretty low.

As for switching it off, all you need to do is disconnect the clamp from the negative terminal. The disruption in electric supply will turn off the battery immediately. Connect the setting back, and the power will be restored in no time.

Battery Disconnect Switch On Or Off When On Shore Power?

Shore power refers to electrical energy from external sources like shoreside berths while the main or auxiliary engine of the vehicle is shut down. So while the main engines are already switched off, is the battery supposed to be turned off as well?

Under normal circumstances, the battery is supposed to be disconnected while the shore power is still activated. Most RV owners tend to turn off the battery when they are storing their RVs for elongated periods.

If the battery is connected to the shore power, it can protect the RV from many external factors like theft and electrical fires. 

Connecting to shore power also has various advantages than connecting to your house’s power supply that produces raw electric energy that needs to be converted by the converter before use. 

Advantages:

  • It is environmentally friendly and doesn’t produce pollution.
  • Less probability of engine overhaul.
  • A reliable source of electricity that rarely fails
  • Converters are not required since it uses 120V naturally. 
  • Easy to plug into your RV without any need for preparations.                                                                                                                                    

Limitations:

  • It doesn’t offer much flexibility since not every RV can run on shore power.
  • The energy provided might not be enough at times of the low tide.
  • The greater the usage, the more money is required to increase the size of the generators.

Conclusion

By now, you should have got your answer regarding the question “Should I Disconnect My Rv Battery When Plugged In?” Well, it is indeed an excellent decision to turn off your battery when you are going to do an inspection or maintenance on your RV. 

However, it is wrong to turn off the battery and expect that the house power supply will be able to provide the required amount of energy to your RV. Of course, if your house uses a 120V electric supply, your RV will work adequately, but that is only until the connection is kept established. 

Remove the connection, and you are back to square one since the RV will refuse to work without any energy to keep it running!
