Types of RV Batteries and Their Advantages
There are several types of batteries to consider when setting up your RV solar system. Each type has its own advantages and drawbacks, and it’s important to know what you’re looking for before making a purchase.
Lithium is the Best Choice for RV Solar Systems
Lithium-ion batteries are the optimal batteries for RV solar installations. They are lighter and more compact than lead-acid batteries and offer a significantly higher energy density. They can also be charged much faster than lead-acid batteries. The only drawback is their higher price point, but given their long lifespan and exceptional performance, they are well worth the investment.
Note that most of the batteries I suggested earlier, can work also in a marine environment. However, if you would like to be able to use your new battery for both your RV and your boat, then have a look at my selection of the top lithium marine batteries. Those will work wonderfully everywhere.
Lead Acid Batteries
Lead acid batteries are the most common type of battery used in RV solar systems. They are relatively cheap, widely available, and can be recycled. They come in two main types – flooded cells and sealed, and each has its advantages.
Deep cycle batteries are designed to handle frequent discharges and recharges. They are ideal for boondocking and off-grid living since they can handle constant cycling. However, deep-cycle batteries are not as efficient as lithium batteries, and require more maintenance than AGM batteries.
1. FLA Batteries
Flooded lead-acid batteries are the most common and widely used type of lead-acid battery. These batteries contain a liquid electrolyte solution and require regular maintenance to maintain proper fluid levels and prevent sulfation build-up. They are typically the most affordable type of lead-acid battery, but require more frequent maintenance and have a shorter lifespan compared to sealed lead-acid batteries. However, they still remain a popular choice among RVers due to their affordability and versatility.
2. VRLA Batteries
VRLA (Valve Regulated Lead Acid) batteries are a type of sealed lead-acid battery, widely used in a variety of applications ranging from home UPS systems to vehicles. Unlike a traditional flooded battery, VRLA batteries are maintenance-free, non-spillable, and can be used in any orientation since the electrolyte is absorbed in either a glass mat, gel or other electrolyte materials.
VRLA batteries are typically available in two different subtypes, AGM (Absorbed Glass Mat) and Gel batteries, based on the electrolyte used within them.
AGM batteries are a type of sealed lead-acid battery. They are more expensive than flooded cell lead-acid batteries, but offer a longer lifespan since they are sealed and do not require maintenance. However, they still pale in comparison to lithium batteries in terms of lifespan and energy density. If you plan to live full-time in your RV and rely on your batteries every day, AGM batteries may not be the best choice.
Gel batteries, on the other hand, use gelified rather than liquid electrolyte and are often referred to as “gel cell” batteries. They offer improved resistance to vibration and shock, as well as to corrosion. Gel batteries are capable of cycling to a deeper depth of discharge and have a lower chance of developing acid stratification, thus prolonging their life span.
Despite their deep-cycle capability, those batteries are still inferior compared to lithium batteries in terms of performance and drawdown capacity.
Because of their ability to handle high-discharge current applications, gel batteries are often the choice for RV, marine, and solar power applications.
Comparing Lead Acid vs. Lithium-Ion, AGM, and Deep Cycle Batteries
When it comes to comparing different types of batteries for RV solar power, there are several factors to consider.
Size, Weight & Energy Density
Lithium-ion batteries are significantly lighter and more compact than other types of batteries, making them easier to transport and install. They also offer a higher energy density, meaning they can store more power in a smaller space.
Lead-acid batteries, on the other hand, are heavy and take up more space. AGM batteries are more compact than flooded-cell lead-acid batteries, but still do not compare to lithium-ion batteries in terms of size and weight. For example, a 100AH lithium battery will weigh around 30 lbs while an AGM 100Ah battery will weigh about 64 lbs.
Deep-cycle batteries vary in size and weight but are generally heavier than lithium-ion batteries.
Lithium-ion batteries are safer than lead-acid batteries since they do not emit toxic gases or require ventilation. They also have a lower risk of catching fire. However, it’s important to note that lithium-ion batteries should still be handled with care and installed properly.
Lead-acid batteries require more maintenance and can emit toxic gases, so proper ventilation is key.
AGM batteries are sealed and do not require ventilation, making them safer in terms of gas emissions.
Selecting the most suitable solar-powered RV battery requires careful consideration of its maintenance demands. Comparatively, AGM batteries necessitate less maintenance than wet cell lead acid batteries since they are sealed. However, AGM batteries still demand appropriate ventilation to function effectively.
Make sure the battery has an efficient charge controller to avoid overcharging, which can damage the battery over time.
Regularly check the fluid levels in your battery if you’re using traditional lead-acid batteries, as this can prevent your battery from drying out and reduce the risk of sulfation.
If you don’t like maintaining batteries, lithium-ion batteries are a great option as they don’t require any maintenance. However, if you prefer lead-acid batteries, then deep cycle batteries are the best option as they require the least maintenance compared to other lead-acid batteries. It’s also important to consider the charging process when it comes to maintenance.
When selecting an RV battery for solar power, it’s important to keep in mind the battery’s longevity.
Although AGM batteries typically have a longer lifespan than other lead-acid batteries, their life expectancy is still markedly less than all types of lithium batteries.
High-performance lithium batteries have a remarkable lifespan of 10 years or more, which is up to five times longer than standard lead-acid batteries. As a result, you can save money in the long run since you won’t have to contend with the recurring cost of replacing AGM batteries with a shorter life expectancy.
Efficiency and Charge Time
It’s crucial to take into account efficiency and charging time when selecting an RV battery for solar power. These two factors directly impact the amount of power available and how often it can be replenished.
Lithium batteries charge about four times faster than lead-acid types, which makes them an excellent option for those who want to minimize downtime and extend their travel time. Although AGM batteries do charge quicker than standard wet cell lead-acid batteries, they still lag well behind lithium batteries.
Depth of Discharge
The extent to which your battery can provide energy before needing to be charged is referred to as depth of discharge (DOD). One aspect that can be complicated with batteries, particularly those made with lead and acid, is DOD. This term is used to describe how far you can exhaust the energy storage of your batteries before needing to recharge them.
A lower DOD is found with lead-acid batteries compared to lithium-ion batteries, indicating that you will not be able to use as much energy from your lead-acid batteries before needing to recharge them.
In fact, lithium batteries can be discharged almost completely, while lead acid batteries can typically be discharged to only 50% or less of their capacity. Effectively, this means that with lead acid batteries, you will not be able to use about half of the stored power!
As a result, lead-acid batteries will lower the effectiveness of your solar system for daily use. That’s why I would warmly recommend that, if you can afford it, you should make the investment needed for lithium batteries.
If you’re planning to power your RV using solar energy, you should consider the expenses involved in buying the batteries. In this case, you have to consider both the short-term and long-term expenses. Lithium batteries may seem expensive at first, but they tend to last much longer and are much more efficient compared to lead-acid batteries. They are also capable of holding more energy and can withstand a much deeper discharge without damage.
Selecting the right battery for your RV solar generator is crucial for seamless off-grid living is a very important step that can deeply influence your RV experience and comfort.
When it comes to choosing a battery for long-term use, lithium batteries may seem expensive at first, but they actually end up being more economical because they last longer and require less frequent replacement compared to AGM batteries. However, for those who are mindful of upfront expenses, selecting a deep cycle lead-acid battery may be a more pocket-friendly option.
