What Types Of Deep Cycle Batteries Are Available?
#1 Sealed lead acid battery
Closed lead batteries are among the most common types of batteries you can have. As their name suggests, they are completely sealed making the battery sealed. Although, they must have valve regulators to reduce the pressure.
When we think about this literally, then we can say that the battery is completely sealed. This is the reason why the battery has the second name VRLA (Valve Regined Lead Acid).
VRLA batteries generate energy through the use of oxygen and nitrogen, and most of them have gels inside that make them shock- or vibration-resistant.
#2 AGM battery
Batteries made with Absorbent Glass are commonly referred to as AGM batteries. This battery is very efficient as it improves the battery’s discharge and recharge capacity.
This batteries are very similar to VRLA batteries and the only difference is that they are more advanced and they are often used to power high-performance motors.
AGM batteries have a voltage absorption range from 14 volts to 15 volts and a floating voltage range 13 to 13.8 volts. It’s important to note for you to get the best out of AGM batteries, you should recharge them before the battery drops below 50%. This helps maintain battery cycle and also ensures that it keeps being charged for longer.
#3 Flooded lead-acid battery
Lead acid batteries are different from the batteries we explained above because they are not protected and they are stored in an acidic container and distilled water.
Unlike AGM Lead Batteries and Sealed Batteries, they require maintenance and you must ensure that the distilled water level is not low. If you are not someone who can do the less rigorous task of having to refill the battery every time, then it’s best to avoid battery flooding.
One good advantage of this battery is that it produces immense power making it ideal for high-end uses. In addition, flooded lead-acid batteries are cheaper, making them a more attractive option.
The battery is also easier to diagnose because most of the times problems happen with the battery, which is due to the acid and water levels. In addition, the submerged lead-acid battery is the most durable of all deep cycle batteries, which means it combines efficiency, energy, and durability.
On the other hand, the battery must be placed in an upright position to prevent battery acid and distilled water from spilling.
#4 Gel Battery
Gel batteries are very expensive and this is for various reasons. The battery is very strong and mostly resistant to shock and vibration. This makes them ideal for aircraft and marine use as they do not turn off due to turbulent motion that can be seen at sea or in the air.
Also, the batteries require little to no maintenance and this is because they are filled with gel, not water. While a deposit is not a routine task, it is important to keep in mind that whenever you need to make a deposit, experts are required to do so.
Furthermore, gel batteries are better able to withstand cold and hot temperatures, and they can perform well in all weather conditions without sacrificing performance. In addition, the battery can be installed in any position you see fit, and it is not in a vertical position like a submerged acid battery.
One bad attribute of these batteries is that they have lower power. However, this drawback can be offset by the fact that the battery discharges more slowly.
#5 Lithium-ion battery
These are the latest battery packs to make and they are among the best when it comes to saving energy and power output. They are very durable and they can thrive in all weather conditions and this is due to the fact that they are resistant to temperatures.
Another thing we like about lithium-ion batteries is that they are lightweight and they can be installed in any position without worrying about spilling. The downside to these batteries is that they are expensive and quite difficult to obtain.
We’ve written about the different types of deep cycle batteries and battery chargers available and we’re sure you’ve learned a thing or two from there. Finally, we assure you that every product we’ve reviewed in this article is of the highest quality, and you won’t regret buying any of them.
