What is a Deep Cycle Battery?
A deep cycle battery is a type of lead battery designed to generate consistent power for a long time. These types of batteries are a wise pick for RVs since they allow you to power up the entire electrical system of your RV when traveling off the grid.
A deep cycle RV battery has the ability to run reliably until its discharge level hits a certain level (80%). Take note that although a deep cycle battery can run up to 80% discharge level, almost all the battery manufacturers recommend not to discharge the battery below 45%.
It is to extend the lifespan of the battery and improve its performance.
Usage of Deep Cycle Batteries
As stated above, deep cycle batteries generate sustained power for a long time, they are suitable for certain applications that need much more than a quick start. Some most common uses where a deep cycle battery is used include,
- Recreational vehicles.
- Golf carts.
- Marine applications.
- Materials handling.
- Renewable energy.
Moreover, although, for certain applications, such as marine uses, hybrid batteries can also be used that offer both sustained power and starting power.
The lifespan of these batteries is significantly shorter than a battery with a dedicated role.
Types of Deep Cycles Batteries
With similar functionalities, there are different types of deep cycle batteries. However, the two most popular types of deep cycle batteries are, sealed or maintenance-free batteries and flooded deep cycle batteries.
1. Sealed or Maintenance-Free Batteries
As the name suggests, Sealed, Maintenance-Free, or Valve Regulated Lead Acid batteries don’t need any maintenance since they are sealed. However, regular inspection is required to keep the battery in working order.
Since these types of batteries are also known as Valve Regulated Lead Acid batteries, they generate energy through the use of nitrogen and oxygen. Most of these batteries have a gel inside, making them vibration and shock-resistant.
2. AGM Batteries
AGM “Absorbed Glass Mat” is an incredibly efficient type of battery as it is known for improving the charge and discharge capabilities of a battery. VRLA (Valve Regulated Lead Acid) and AGM batteries are somewhat similar.
However, the only difference is that AGM batteries are more advanced and used for high-end purposes.
Moreover, the AGM battery’s voltage absorption range runs from 14 to 15V, while the float voltage range runs from 13 to 13.8V.
It is worth noticing that to get the most out of AGM batteries; it is essential to make sure the discharge level of these batteries doesn’t go below 50%.
This not only improves the battery lifespan but also enables it to hold the charge for extended periods.
3. Flooded Deep Cycle Batteries
Flooded deep cycle batteries need regular maintenance. For instance, when the electrolyte levels hit a certain point, they must be refilled by the user correctly to keep the battery in its optimum working state.
Unlike the Sealed Lead and AGM batteries, they do need maintenance. Users of these batteries are required to make sure to maintain the distilled water levels present in the battery.
However, these batteries’ biggest advantage is they produce immense power, which makes them ideal for high-end purposes.
Moreover, these batteries are also significantly cheaper, which makes them an attractive option. Furthermore, they are also easy to diagnose when an issue occurs with the battery.
They are also highly durable and combine power, efficiency, and durability at the same time.
The biggest disadvantage is you have to place them in an upright place so that the distilled water and acid don’t spill out of the battery.
4. Lithium-Ion Batteries
Lithium-Ion batteries are the newest ones. They are the best when it comes to power output and energy efficiency.
The batteries are also incredibly durable and can thrive regardless of the weather conditions, which means they are also temperature resistant.
Lithium-Ion batteries are also exceptionally lightweight and can be mounted in any desired position without worrying.
However, they’re a bit more expensive than the batteries mentioned above and quite hard to find.
5. Gel Batteries
When it comes to the cost, Gel batteries are the most expensive ones available out there, and rightly so.
They are incredibly strong and highly resistant to shocks and vibrations. It means they are ideal for aircraft and marine use since they don’t turn off due to the turbulent movement that can be occurred in the air or sea.
Moreover, these batteries need very little or no maintenance at all because they contain gel instead of water. Although they don’t need a refill more often, when they do, experts are required to have it done.
The batteries are also weather-resistant and can withstand bitter and extremely harsh temperatures. You can install the batteries in any position you desire.
The only downside of Gel batteries is their power, which is lower than other deep cycle batteries.
So, what points should you look for when selecting the best deep cycle RV batteries?
When looking to get the best deep cycle RV battery, it is a must to consider some deciding factors. Make sure to look for these points when making a purchase.
Factors to Consider when Buying a Deep Cycle Battery for RV
1. Amp Hours or Hours of Use
When you’re out in the market to purchase a deep cycle RV battery, make sure to check how long the deep cycle battery last before it requires to be recharged.
If you are looking to get a battery for high-end purposes, make sure to purchase a battery with higher amp-hour ratings.
2. Weight and Size
The second important factor to consider when choosing a deep cycle RV battery is its size and weight. It is because the smaller the battery will be, the easier it will be to move from one place to another.
When it comes to weight, lighter batteries do not add unnecessary weight to your rig, which is important considering your tow vehicle’s towing capacities.
3. Charge Time
Charge time means the time that the battery will take to be recharged after use. Batteries with low charge time are great since you can use the battery and then quickly recharge it when it needs to be recharged.
Generally, this detail can be found in the battery manual.
4. Volts
Volt rating of a battery is another important factor. It shows how much power it has available for use. If you need a deep cycle battery for high-end purposes, you should go for a battery with higher volt ratings.
Final Words
There you go – the 5 best deep cycle RV batteries.
I have discussed everything about deep cycle batteries that you need to know before purchasing one.
If you are looking to have a deep cycle battery for your recreational vehicle, make sure to consider the ones I have outlined above.
All of these batteries are reliable and deliver immense and consistent power. You can also compare their features, so you get the one that is perfect for your power needs. Good Luck.
