Key Takeaways

  • The price of an RV battery varies on the type of battery you get
  • Lithium batteries cost the most but last the longest
  • Lead acid and deep cycle batteries are less money but don’t last a long
  • Consider a refurbished battery if you want a shorter term battery for less money
  • Battery life can be extended by maintaining a battery well

The battery is a pretty important piece of equipment for your RV. How much do RV batteries cost, and what factors change costs?

Prices range from as low as $100 for a lead acid battery to more than $3000 for higher end lithium sets. Lead acid batteries are more traditional and common while lithium batteries last longer and require less maintenance.

We’ve performed a detailed analysis of batteries and their costs, in addition to the years of experience we have with RVs and their battery costs. We’ll explore the range of costs you can spend on a battery in addition to some of the positives and negatives of each battery type to inform you about costs and the future potential for each battery.



How Much are RV Batteries?

As an avid RV enthusiast, I understand how important it is to have a reliable battery system. One of the most critical components of any RV battery system is the battery itself. In this section, I'll break down the cost of RV batteries to help you make an informed decision when shopping for one.

Cost of a Lead Acid Battery for Your RV

Lead-acid batteries are the most common type of battery found in RVs. These batteries are relatively inexpensive and offer a decent lifespan when maintained properly. The cost of a lead-acid RV battery can range from $100 to $500 depending on the brand, size, and capacity.

It's important to note that not all lead-acid batteries are created equal. There are three main types of lead-acid batteries: flooded, gel, and AGM. Flooded batteries are the cheapest but require regular maintenance. Gel and AGM batteries are more expensive, but they require less maintenance and have a longer lifespan.

Cost of Deep Cycle RV Batteries

Deep cycle batteries are designed to discharge and recharge repeatedly without damaging the battery. These batteries are commonly used in RVs to power appliances and electronics. The cost of a deep cycle RV battery can range from $100 to $1000 depending on the brand, size, and capacity.

It's important to note that deep cycle batteries come in both lead-acid and lithium options. Lithium deep cycle batteries are more expensive but offer a longer lifespan and faster charging times.

Overall, the cost of an RV battery system can vary widely depending on the type of battery you choose. It's important to consider factors such as lifespan, maintenance requirements, and charging systems when making your decision.

Cost of Lithium RV Batteries

Lithium batteries are becoming increasingly popular among RV enthusiasts due to their lightweight, high energy density, and long lifespan. However, they come with a higher price tag than lead-acid batteries. The cost of a lithium RV battery can range from $500 to $3000 depending on the brand, size, and capacity.

One thing to keep in mind when considering a lithium battery is that they require a special charging system to prevent damage. This can add to the overall cost of the battery system. There are other upsides too though, including being nearly maintenance free.

What is the difference between lead-acid batteries and deep cycle batteries?

The primary difference is in the thickness of the lead and the power. A deep cycle battery tends to last longer but doesn’t provide as much power. While not having as much power doesn’t sound great, you can get a stronger battery that provides more consistent voltage over a longer period of time.

Tips for Getting the Best Price on RV Batteries

When looking for an RV battery, it's important to keep in mind that prices can vary greatly depending on the type and quality of the battery. Here are a few tips for getting the best price on an RV battery:

Shop around

Don't settle for the first battery you come across. Shop around and compare prices from different stores and online retailers. You may be able to find a better deal by doing some research.

Look for sales and discounts

Keep an eye out for sales and discounts on RV batteries. Many retailers offer discounts during certain times of the year, like Black Friday or Cyber Monday. You may also be able to find coupons or promo codes online. You should check for “Winter” RV batteries in the winter off season.

Buy in bulk

If you need to replace multiple batteries, consider buying them in bulk. Many retailers offer discounts for bulk purchases, which can save you money in the long run. Extra batteries can be stored at home or within your RV.

Consider refurbished batteries

Refurbished batteries are often significantly cheaper than brand new batteries, but they may not last as long. If you're on a tight budget, a refurbished battery may be a good option. Battery recycling is a great way to reduce your impact on the environment too.

Battery recycling

Some battery stores and retailers charge you a small amount for disposing of an RV battery. Others do the complete opposite and either connect you with programs that pay you to do battery recycling or pay you for it themselves.

Shop at clubs

Club warehouses like Sam’s Club and Costco are very popular with RV owners for a reason: They offer good prices on large items and include batteries and tires for great prices. Get a membership and Sam’s Club and you’ll see what we are talking bout.

A couple of brands we like from clubs is the PowerArmor Max Solar and Trojan Reliant batteries.

Getting the best price on an RV battery requires some research and consideration. By shopping around, considering the type of battery, looking for sales and discounts, buying in bulk, and considering refurbished batteries, you can save money on your purchase.

How to Make RV Batteries Last a Long Time

As an RV owner, I know how important it is to make sure my batteries last a long time. After all, replacing batteries can be expensive and time-consuming. Here are a few tips I've learned to help make RV batteries last and to avoid premature battery replacement.

Charge regularly

Regular charging is key to extending the life of your RV batteries. Be sure to charge your batteries at least once a month, even if you're not using your RV. This will help prevent sulfation, a process that can damage batteries over time.

Use a battery tender

A battery tender is a device that can help keep your batteries at the right level of charge. It's especially useful if you store your RV for long periods of time. A battery tender can help prevent overcharging or undercharging, both of which can damage your batteries.

Reduce parasitic loads

Parasitic loads are devices that use power even when your RV is turned off. Some common examples include clocks, stereos, and appliance circuit boards. To reduce parasitic loads, unplug devices when you're not using them, or install a battery disconnect switch. Have your electrical circuit system inspected regularly too.

Use the right type of battery

There are many types of RV batteries available, including flooded, gel, and AGM batteries. Make sure you choose the right type of battery for your RV, and follow the manufacturer's recommendations for maintenance and charging.

Keep batteries clean

Dirt and corrosion can damage batteries over time. To keep your batteries clean, use a wire brush to remove any corrosion, and wipe the terminals with a damp cloth. You can also use a battery terminal protectant to help prevent corrosion.

By following these simple tips, you can help extend the life of your RV batteries and save money in the long run. Remember to always follow the manufacturer's recommendations for maintenance and charging, and don't hesitate to contact a professional if you have any questions or concerns.
