Factors to Consider in Buying the Best Deep Cycle Marine Battery
What are the several factors you need to consider when buying a trolling motor battery? In order to save time and money, you need to do a couple of research about these factors, which may include the price, the battery’s brand reputation, and reviews from other customers. We specify all that you need to know about trolling motor batteries to guide you.
Know the Three Types of Trolling Motor Battery
First, you need to know the three types of trolling motor batteries. These are the following:
Absorbed Glass Mat (AGM) –This battery is made out of a glass plate and has a substance that’s somehow the same with gel. Because these types of batteries are entirely enclosed, adding distilled water to them is not necessary. Compared to wet-cell batteries, they can last longer. They can even last up to three to four years. The drawback, however, is that they are more expensive than wet-cells because of this longevity.
Wet-Cell –These types of deep cycle marine batteries are the most basic and the most affordable. They can deal with several and continuous power recharges and drains. They are also very durable. The challenge for you, however, is the maintenance. Wet-cell batteries would usually demand to top off with distilled water. Compared to the absorbed glass mat (AGM), they do not last that long. After a year or two, it might need a replacement.
Lithium-ion – Mostly, these types of batteries are used for smartphones, so they might be quite familiar to you. Bigger lithium-ion batteries are usually used to help power trolling boats. Because of their extensive durability, these types of batteries are quite famous and among the most effective.
This lasts longer than a wet-cell and even with Absorbed Glass Mat (AGM). When stored under a 105-degree temperature, this battery could last for around ten years! This is thrice the lifespan of an AGM battery. Because of this amazing feature though, this type of battery is also very expensive compared to other types.
Other Important Factor to Consider
Now that you know these three types of battery for trolling boats, you might already have an idea about which would suit you best. However, you should know not only the types of batteries but the things you should look for when buying one. Here are some important factors:
Amp Hours (Ah) –This is about the number of amps that your battery draws in every hour. What this indicates is how long the battery would last after a single charge. You would find batteries with different amp hours. When your speed is slow, 35Ah batteries would last around seven hours. 100Ah batteries, on the other hand, could even last for around 20 hours.
You would want to choose that with a higher Ah to make sure that your battery would last long after a single charge, as you won’t be going at slower speeds all the time. Also, getting 12V batteries for the trolling motor could help provide more power.
Battery Lifespan – Like what has been mentioned in the types of batteries, each type has different lifespans and it would be more advantageous if you choose that which would last longer. However, two batteries that are different but are under the same type might have a different lifespan as well. One might last longer than the other.
Checking customer reviews would help you identify what brand could really last long. One tip that would help you choose is also identifying the warranty offered. Usually, longer warranties mean a longer lifespan.
Durability and Vibration Resistance – Traveling over choppy waters (the way most fishing boats do) might cause vibrations that could bother your batteries. There are batteries, however, that are vibration resistant and could withstand this occurrence. Some batteries also have features that improve durability like shock-resistance and is spill-proof.
Size –You need to make sure that your boat size could accommodate the size of the battery. You need to make sure that your boat could also carry the weight of the battery, so you really need to look for the most appropriate size. Small boats may accommodate only up to 40 pounds. Check the dimensions of the battery you’re buying and examine if it fits your boat.
Ease of Use – Because you would need to install your battery on your boat, you need to know if installation instructions are available and are easy to follow. While some batteries can be mounted in any position, there are those that really require a particular set up.
You would also want to know how your battery has to be maintained to make sure that it remains useful.
Versatility – Choose the most versatile one. There are batteries that could power not only your boat but also other gadgets you might be using while you’re on board in your boat. Some batteries may even be useful for other things like motorcycles, jet skis, and even scooters.
