One of the main things when it comes to maintaining your RV when you’re on the open road is to make sure your battery is charged and ready. When your RV battery isn’t in use, it might lose its charge, putting you in a tight place if you’re already at a campsite or wanting to go out of town. Fortunately, if you have an RV battery charger on hand, you can simply maintain, jump start, and charge your battery.

Why You Need an RV Battery Charger

Increase the life of your battery

Utilizing an RV battery charger can extend the life of your present battery. You may spend years without replacing your battery, which will save you money in the long run.


If you own an RV battery charger, you can use all of your RV’s appliances while camping without concern. No matter what you’re operating or powering up, you can effortlessly recharge — or preserve a charge.


When you’re on the road, an RV battery charger provides you additional alternatives. You can recharge your battery whenever you want, without thinking about how long your vacation will be, how many appliances you’ll be using, or how you’ll find a charging station if you need one.

Types Of RV Battery Chargers

Converter chargers

The primary type of RV battery charger is a converter charger. This charger converts 120 volts of shore power to 12 volts DC electricity, removing the requirement for your RV battery to provide DC power when plugged in. A converter charger may also be used to charge the RV battery while it has extra capacity, preventing overcharging and potential damage. There are two types of converter chargers: single-stage and multi-stage.
Single-stage means that there is just one cut-in and cut-off setting on the regulators. The battery is charged until the cut-off voltage is reached (usually 14.5V for flooded 12V lead acid batteries).

Multi-stage chargers use the application of precise regulated charging phases to enhance battery charge, health, and longevity is known as multi stage battery charging.

Inverter chargers

The most common form of charger used in modern RVs is an inverter charger. This type of battery charger has all of the same advantages as a converter charger, with one major exception: when there is no shore power available, an inverter charger produces 120 volts of alternating current from a 12-volt battery. Multi-stage chargers are often always included with inverter chargers.

Solar power chargers

Solar-powered RV battery chargers are a relatively new alternative that may deliver a continual supply of electricity using just sunshine. Solar panels on these chargers collect sunlight and convert it into electricity, which may then be used to deliver varied amounts of power to you and your RV batteries. The wattage of the charger determines how much power it can provide; a solar-powered charger with a 150-watt solar panel, for example, should be able to power your RV and its appliances for a whole day.
