FAQs for Buying RV Battery Charger

What do I need to look for in a battery charger?

When purchasing a charger, you have to have a clear understanding of the type of battery it is as well as its voltage. This information will ensure that the two items are compatible and will not damage one another.

Another important consideration is the type of charger. Multi-stage chargers are better for maintaining the health of your battery as they reduce the likelihood of overcharging.

How long do deep cycle RV batteries take to charge?

The time required to charge deep cycle batteries depends on a variety of factors. The voltage, how much charge it already contains, and the specifications of the charger being used are all key aspects.

Charging a 12V battery from a completely discharged state could take as long as two days. However, this time is drastically reduced with a charger with higher amperage.

Can fast-charging damage my battery?

Faster is not always better when it comes to charging batteries. The batteries themselves could become damaged in the process. You are not recommended to fast charge smaller batteries.

A deep cycle battery, however, has thicker plates than other types of batteries, and so they are not as easily damaged. Sulfate corrosion is also less of a risk. Yet, it’s still better to charge them more slowly if possible, to avoid the risk of overcharging.

Can you charge a deep cycle battery with a regular battery charger?

Before pairing any battery and charger, you should check that the charger is suitable for that type of battery. Keep in mind also that the voltage is important — many RV batteries are 12V.

Automatic chargers are generally considered to be better suited to charging deep cycle batteries. The reason for this is the charger will determine the voltage requirements at each stage of charging. The result is an optimized charge and a longer-lasting battery.

How long should an RV battery last?

With appropriate maintenance, depending on the battery type, they can last anywhere from five to seven years. Do consider that deep cycle batteries are more complex than other varieties and, as such, require more care.

To get the very best service life from your battery, you should avoid letting them fall below 50% charge. If this does happen, you should charge them immediately. At below 20%, the battery is likely to be permanently damaged.
