If you have jumper wires, your vehicle can charge your RV batteries. Let’s look at the procedures for charging an RV battery from a car.
What is RV battery
RV batteries are lead-acid batteries, which have numerous cells connected in series. Lead-acid batteries are composed of plates, lead, and lead oxide immersed in an electrolyte composed of 64% water and 36% sulfuric acid. Lead-acid batteries do not generate power; rather, they store it.
How to charge RV battery from the vehicle
When planning a trip, don’t forget to understand how to charge an RV battery from a vehicle. Because when the battery dies, the entire adventure comes to a halt, erasing all of the fun and excitement. It directs you to repair the dead battery rather than doing something more enjoyable!
Are you concerned with using your car to charge your RV batteries? Then you’ve come to the correct spot! A camper’s battery may be recharged with minimum effort by using a transformer that converts AC power to DC electricity. Let’s have a look at the article How to Charge an RV Battery from the Vehicle.
Step 1
First and foremost, park both the vehicle and the RV close enough to one other for charging. Make sure you park your automobile near your recreational vehicle for the next steps. Keep your car operating.
Step 2
Before attempting to charge your RV batteries, you should first inspect the battery connections. There could be some loose ends. This can cause your battery to appear dead when it is fully charged.
Step 3
While all of your RV’s electronic devices are unplugged, keep the car or charging vehicle running. Set the RV’s emergency brake to avoid any mishaps. Before you begin charging the RV batteries, ensure they are turned off.
Step 4
Let’s go to the following stage now that you’ve ensured that all electricity to the RV has been switched off. Remove the caps from the RV batteries and open the hood of the automobile you’ll be using to charge it.
Step 5
Take the red clamp off the jumper cables and connect it to the positive pole of the RV battery. If you see a ‘+’ symbol on it, you know it’s the positive pole.
Step 6
When finished, connect the negative clumps of the jumper wire to the negative poles of the automobile and RV batteries. Be aware that clumping them on the battery may result in sparks. The negative pole is dark in color.
Step 7
As long as the RV battery is completely charged, you can drive your automobile. The clamps should then be removed. Remove the RV batteries first, followed by the vehicle battery. The order would be the same as the red one.
Step 8
Allow your vehicle to run until your RV battery is charged.
Step 9
Follow the steps below to remove the clamps. Remove the black clamp that is attached to the RV battery. Then, repeat with the clamp that is hooked to your automobile battery. With the red clamps, repeat the process, starting with the RV battery and ending with your car battery.
Step 10
You may now remove the caps from the RV and automobile batteries.
Step 11
You now have an RV battery that is fully charged.
How To Take Care of an RV Battery
Reduce power usage while the engine is turned off. When the engine is turned off, the battery can serve as a power source. Charging the phone when the motor is turned off can result in battery drain because the alternator does not replenish the battery’s power. Doing so regularly will gradually deplete your battery.
Avoid taking too many short excursions as much as possible because the alternator will require enough time to completely charge the battery. However, if you don’t drive great distances, it may be difficult to attain. If you just make short travels, the voltage of the battery will gradually diminish.
It might help to drive for at least two hours to restore the battery’s full charge.
It could assist to drive for at least 20 minutes every day to regain the full charge of the battery.
Classification of RV battery
Based on their design, the most popular rechargeable batteries are being utilized in RVs (a) Lead-acid flooded wet cell, (b) Valve-regulated lead-acid (AGM), and (c) lithium-ion batteries.
