Deep cycle batteries have a range of uses and applications. These batteries are designed to be regularly discharged to almost the full capacity and then recharged again.
This differs from the battery you would use in your car, because these batteries only discharge a small burst of energy to start the motor, rather than using a large amount of energy consistently over a longer period of time. Deep cycle batteries have gained popularity because they can easily be used with energy systems like solar power in your home.
Deep cycle batteries are lead-acid and can take different forms. They can be either flooded (FLA) or Valve regulated lead acid (VRLA). With the regulated types you get either AGM (Absorbed Glass Mat) or gel options. Each of these types have different applications and uses.
The most recent additions to the team can also be lithium-ion based. The lithium-ion based batteries have started to become more popular where the flooded batteries resemble those you use in your car and are the most recognizable.
When you start to look at a battery there are two factors that you can use to see what the battery has to offer. This will be its Volts and Amps. Amp Hours (Ah) refers to the discharge rate. This means it is a measure of the time it takes to discharge the battery before you need to charge it again.
You may also notice a C rating. The C relates to the idea of constant discharge. So a battery with a rating of say C20, will deliver the Ah capacity if it is used and discharged over 20 hours.
So if you know what size and power battery you need, you will also need to decide what type. We will take a look at the different types and cover where they fit best.
These batteries are completely sealed and will not need to be topped up or opened at any time. They are designed with a valve that activates when they are recharged by using high voltages.
They can be transported easily and makes them suitable for boats, caravans and other moving vehicles that need a secure battery. They can be mounted on their sides or ends without any problems, where lead-acid batteries (flooded) need to be kept upright and sometimes need to be topped up with water. These batteries also charge quickly and are quite robust.
The flooded or wet battery is one of the most basic types of batteries and it has been in use for ages. These lead-acid batteries have liquid in a container but are not completely sealed like the AGM or Gel type batteries.
These batteries have to be installed upright, and can’t be tilted or put on their sides. The lead plates need to remain within in the liquid to work. They are larger and heavier for the amount of power they offer in turn. They also need a bit more maintenance and monitoring.
They often need to be topped up with distilled water. But even though they need a bit more attention, they are easy to use, easy to fix and some of the most inexpensive batteries available for their power.
These batteries are also sealed like the AGM type, but have a gel based electrolyte. They work on the same good old lead-acid system, but with a closed system. These batteries handle extreme temperatures very well (much better than their other counterparts), but also don’t mind shocks or vibration.
They are suitable to exterior use where you might encounter quite a bit of moving and shaking, like on a boat or in a motorcycle. They also need much less maintenance than flooded batteries, so if you won’t be able to check up on the battery regularly these gel types are a good choice.
The latest addition to the range of deep cycle batteries that are available for normal use are Lithium-ion types. They differ a bit from the usual lead-acid design. These batteries are usually applied in connection to solar panels and other off-the-grid home energy solutions.
They can function as storage solutions for home energy, but are more expensive than other options. These batteries are also quite light, have low maintenance and long lifecycle.
When you look at the range of different deep cycle batteries that are available, you could perhaps feel a little confused. In this piece we tried to help clarify things a little so you can make easier choices when selecting a battery. Now when you look through the choices, you should be able to pick the one that best fits your needs with ease.
