How Long Do RV Batteries Last? Maintain RV Batteries

How long do RV batteries last? There is no single answer to this question because not all batteries also last long. It depends on certain factors, including usage and type of battery. But in this post, we’ll provide you with a general view on how long they could last. Also, we’re sharing some tips on how to maintain and extend its life.

Common factors affecting battery life

While high-quality batteries may be able to last up to seven years, there are still factors that affect this lifespan. Some of them are –

How low the battery is sitting

If you’ve just bought an RV for sale, you might have to replace its battery. As the RV might have been sitting for a long time, its battery life may not be long. The battery might have also been incorrectly stored. So, for the best results, you might want to get a fresh set of batteries for your used RV.

Temperature RV batteries

Changes in temperature also affects battery life. If you’re traveling places with different climates, you might encounter issues with heat and moisture. This also applies if you have parked your RV in a cold or hot temperature area.

Multiple appliances draining the battery

It’s another factor affecting the performance and life of your battery. But if you would prevent your battery from draining and maintain it well, you can extend its lifespan.

How long do RV batteries last?

It is one of the most common questions among recreational vehicle and mobile home owners because batteries are crucial in running different gadgets and devices in the RV. And if you’re not connected to the grid, the more important keeping a functioning battery is. It’s because you need it to start the engine, heat water, and cook, among other things. That’s why many people also like to learn about the proper ways of charging and storing their batteries.

The average lifespan of a battery

How long does it last on the average? It can last up to six years or even more, depending on how you take care of it. It can also last longer if you would monitor our power usage and demands factoring the level of juice your battery has.

On the other hand, it might not last as long if you won’t treat it well and check your power needs. In this case, it might only last a good two or three years. Nevertheless, the number of years it would last depend on how you maintain and use it, including if you’re not letting it drain or overcharging it.

So, the bottom line, the RV battery can last up to seven years if treated right or only up to three years if not. That is why aside from knowing how long it can serve you, know how to properly take care of it. In the following, we’re sharing basic tips on how to make it last longer.

Get a high-quality battery

From the start, you must invest on a quality battery to ensure it will last. While some may be pricey like lithium-ion ones, they are a whole lot better than other options are. For one, these batteries have a longer shelf life than a typical deep-cycle battery, which might only last for 500 cycles. Superior lithium-ion batteries can last up to 5,000 cycles.

Don’t let a 12V battery discharge below 12 volts

A fully charged battery will have a reading of 12.7 volts. When it’s below 12 volts, it may mean that it is at or below 50% charged state. To check, you can use voltmeter to measure the voltage for an idea of the depth of discharge of the batteries. In this case, you will know when you need to recharge the battery. First, you must set the voltage on DC, and t hen put the red lead on the positive terminal, while the black one on the negative terminal to read the voltage of the battery.

Limit discharge depth

Another important tip to remember – limit the discharge depth. At the very least, you must not let it go below 50% charge. Most sources reveal that those batteries which level of discharge to only 50% can last longer versus those discharged at 20%.

Do not overcharge the battery

You can also extend your battery’s life by not overcharging it. This is also bad to keep it connected to a power source when it is 100% charged.

Get an RV monitor that can help you check how much charge remains in the battery and if you need to recharge it. With it, you can also check for how long you can go without recharging the battery or connecting it to a power source.

Always clean your RV batteries

Clean the connection points and terminal points of the battery to keep it well-functional. In this way, you can prevent dirt and rust from forming or building up. Doing so, you can maintain the top condition of your battery.

Check the charge state of the battery

On a regular basis, you must check the charge state. This can help in extending the life of your battery. It will also help to recharge a drained or discharged battery as soon as possible.

And when it’s hot or when the battery’s in use for a long time, you must check the water level more often. In addition, do not forget to check the electrolyte levels. It will also help to add distilled water as needed to extend the life of your lead acid battery.

Keep the battery connect in the off position when RV is not in use

When your RV isn’t in use, you must switch the battery in the off position. It will help in preventing any parasitic loads, like those appliances and items, which are drawing power from the battery even when they’re not in use. A few examples, including radios, clocks, and appliance circuit boards.

Now, you know that there are certain factors affecting it, including temperatures, overcharging, and other factors. But if you would like to maintain and extend their lifespan, you might want to follow the tips highlighted earlier.
