how to charge battery with generator

knowing the type of battery you have

RV batteries come in all shapes, sizes, and types, which means they don’t all function the same. Before charging with a generator, it is crucial to determine the type of RV battery as each type has different requirements. The main battery types to identify are 12-volt and 6-volt batteries, and whether they are deep cycle batteries, as these factors directly affect charge duration.

charging battery with generator: a step-by-step guide 

To successfully charge a battery with a generator, careful preparation, and attention to detail throughout the process are vital. Here’s a step-by-step guide on how to do it:

step 1#. prepare the generator

Place the generator on a level surface and verify the availability of the required fuel type and fuel level. Once confirmed, start the generator and let it run to bring the engine to optimal temperature. Make sure the generator’s output meets the battery charger voltage requirements.

step 2#. connect the battery charger to the generator

Next, you need to connect the battery charger to the generator. Most chargers simply plug into the generator like any other device. Before making this connection, make sure the generator is turned off to avoid any electrical spikes.

We need to connect the battery charger to the battery. Every battery charger comes with a pair of clips, usually alligator clips or similar devices, designed to secure to the battery terminals.

Connect the charger’s positive clip (usually red) to the battery’s positive terminal. Then do the same thing with the negative clip (usually black) of the negative battery terminal.

step 3#. set up and plug in the battery charger

After starting the generator and letting it run for a few minutes, then after connecting the battery charger to the generator, you can connect the other end of the charger to the battery. Connect the positive clamp (usually red) of the charger to the positive terminal of the battery. Then do the same with the negative clamp (usually black) to the negative terminal of the battery. Once the connections are secure, you are ready to turn on the generator.

After verifying that all connections are correct, connect the battery charger’s power cord to the generator’s AC outlet and start the generator.

The charger will then perform one of several actions depending on its type, such as automatically shutting down when the battery is fully charged, entering trickle charging mode, or other appropriate functions.

Monitor the battery charger’s indication as it may display a full charge indication after the charging process is complete.

step 4#. disconnect and turn off

Once the battery is fully charged, you can turn off the charger and disconnect it from the battery terminals, starting with the negative terminal and removing the black (negative) clip first, then the red (positive) clip.

If you have extra batteries, you can use a similar process to charge them. Once all batteries are fully charged, you can turn off the generator.

charge battery with generator FAQ

The two types of generators are AC and DC. The battery uses DC power, so you can use a DC generator to charge the battery, or you can also use a battery charging circuit after the AC generator to charge the battery.

Your RV battery's total charging time will vary depending on various factors, including the output of your generator, the capacity of your batteries, the number of appliances you use, and how many batteries you are charging. If your RV or camper battery is 20 - 30% dead, it can take 8-10 hours to charge fully. If your battery is nearly complete, charging to total capacity may only take a few hours.
