Types of RV Battery Chargers

There are a few main types of RV battery chargers. The following section will discuss the features of the most commonly used types.

Converter Charger

This is a basic charging system. It can convert 120V shore power into 12V DC power. This means the battery won’t be needed to provide DC when plugged in. It’ll also charge the battery only when it has space, eliminating overcharging damage. The device can produce 55 amps of direct current and has the ability to power a variety of appliances. These batteries can either be single-stage or multi-stage.

Inverter Charger

Most modern RVs will use an inverter charger. This has all the same features as the standard converter charger, however, it has the ability to produce 120V  of alternating current from the 12V battery, when there’s no shore power available.

Solar-Powered Charger

Solar-powered RV chargers are a great way to access a constant stream of energy. Different sizes offer varying levels of power. This also depends on the weather conditions. A large, 150-watt solar panel can fully power your RV for a day, as long as you have a panel that offers 14V or more. However, solar panels take a lot of planning and maintenance.

How to Choose a Battery Charger

Like all good products, there are plenty of features that make a unit unique or stand out from the competition. The following section will highlight and discuss the features you should be looking out for when searching for your next battery charger.

Vibration Absorption

You need to ensure that it can effectively absorb any vibrations that it creates or has some sort of cradle feature that keeps it off the ground. There are two reasons you should look for this; the first reason being that vibrations can damage your charger battery. Secondly, they can cause some serious noise that really gets on your nerves.

Battery Capacity

Battery capacity is measured by how many amps of power it can offer per hour. The higher the capacity, the better your power situation will be.

However, a higher the capacity usually means that the battery will be larger, so you’ll need to make sure you have the best size for your RV. The best thing to do is to understand how much energy you consume each day and then try to find a battery that can offer the closest to that without sacrificing too much space.

Voltage Power

The voltage is the potential electrical difference. You’ll find that deep cycle and starter batteries will have a 12V DC. This can also be achieved easily by using two 6V DC batteries and joining them together. These aren’t the most powerful, as you can get natural systems like a solar panel that provides 24V batteries, so make sure to look around for the best option.

Cautious Considerations When Buying a New RV Battery Charger

When using new electronics or technical products, there are certain risks attached and you should always be aware of those risks in order to avoid them. The following section will discuss a few cautions we’d like to offer before messing around with your battery charger. The main risks aren’t with the battery charger, but with messing around with the actual battery itself.

Explosive Gas

One of the dangers of lead-acid batteries is the hazardous hydrogen gas it creates. You should ensure adequate ventilation when charging using this method, as a simple spark could cause an explosion.

Life-Threatening Acid

Another hazard is the sulfuric acid that’s included inside the battery. If that is spilled on someone, it would burn through their clothes and could mean life-threatening injuries. Make sure to have the necessary safety casings and features to stop these accidents from happening.

Conclusion

Charging your battery can be a dangerous process and it can also be a long process. However, if you follow our advice and all the research, you’ll be fine. We hope this article has helped educate you on what features to be looking out for when battery charger shopping.
