Best Trolling Motor Battery Review 2017

Trolling motors are important especially to be utilized as the main power source of your motorboat or kayak when fishing. With it available, you need not use the conventional way of travelling on water which refers to paddling your way through the waters to get a good catch when angling. You can also use this battery to charge up your fish finder or laptops. However, to view the fishes underwater, it is best you get a underwater camera.

Deemed as extremely convenient, you can move at varying speeds simply by adjusting the speed of the motor according to your preference and the calmness of the water. Usually, the calmer water requires low power for your boat to propel forward hence using up very little charge from the motor.

The best trolling motor battery lets you remain on water for long periods of time without draining its charge quickly. That being said, it is highly essential for it to hold charge for long hours as well as recharge quickly. You should always keep in mind, not to fully use up the battery until it’s completely depleted because then, the recharging process will take super long.

In addition to that, trolling motors require consistent and steady supply of electrical power, so you should either use the dual purpose or deep cycle battery. Refrain from using starting batteries as the motor battery. In terms of battery type on the other hand, they can be divided into 2 which are the lead acid well cells and the AGM batteries.

The lead acid wet cell requires frequent maintenance in which you need to top it with water whereas the AGM (Absorbed Glass Mat) batteries has a longer life span and is maintenance free. The factors that affects the performance of your product are battery type, AH (Amperage Hour) rating, weight/size, durability and lastly maintenance.

Battery Type

There are two main battery types which are the Absorbed Glass Mat (AGM) as well as the lead acid wet batteries. The wet cell is a lot cheaper than the AGM, however they have short life span of about 1 to 2 years. You also need to do maintenance frequently, in which you need to top them off with water to keep them going.

The AGM on the other hand has a longer life span. Its electrolyte is held in a sealed glass mat, unlike the wet cells that freely flood the plates. Hence why, it has a longer life span of about 3 to 5 years. Another plus point is that, it don’t require any maintenance. You can mount it in any positions too because it is spill-proof and leak-proof.

Amp Hours (AH)

Deep cycle batteries are measured in amp hours (AH hours). It measures the amount of charge in the battery that allows an amp of current to discharge for one hour. The number of amp hours on the other hand measures how much electricity it can hold, which acts as the main power source for your trolling motor.

The higher the amp hour rating, the more power it has and it will hold its charger much longer. For example, a 110 amp hour battery can produce 110 amp hours of current to a trolling motor to make it run.

Weight/Size

The weight and size depends on the user’s preference. The larger ones are usually able to hold more AH rating and longer capacity of charge. However, you need to make sure they are able to fit your boat. If you have a small boat such as kayaks, having a heavy battery will just weigh down your boat hence making it move slowly and spoil your motor in the long run because it won’t be able to support the weight exerted.

So, you need to make sure the limit of the battery weight is less than 40 pounds on a small boat. The lighter ones also will be more convenient for you to carry. Apart from that, some products come with handles for easy carrying to your speedboat for instance. Most of the product dimensions are usually stated, you can make estimations on whether it can fit your boat or so.

Durability

To ensure its durability, your product should be shock-resistant as well as vibration free. Your fishing boats will most probably be in contact with choppy waters especially if you plan on fishing in the sea, hence why a motor without vibration will come in handy for a better fishing experience.

Apart from that, most products mainly with AGM technology are spill-proof. In other words, the electrolyte is totally absorbed by the AGM, hence it is classified as non-hazardous and non-spillable. And since it has a low chance of spilling, you can use the battery for a long time, thus contributing to its durability.

Maintenance

The maintenance mainly depends on the type of battery it utilizes. As mentioned above, the ones powered by AGM does not require any maintenance. Despite any mounting position whether sideways or top or bottom, the electrolyte inside will not likely leak hence no need for maintenance at all, for your added convenience. Conversely, the wet cells require frequent maintenance by re-filling them with water.

Not only that, the batteries are sealed with thick plastic casing for storage to prevent the electrolyte from spilling over from it as well as maximize the vibration and shock resistance to ensure the high service life and performance of your battery.

Cost

The trolling motor battery you purchase should be of high quality and well-worth your investment. The price usually varies due to the weight and size, rate of recharging, how long the charge last, AH rating and many other factors. Conventionally, the expensive ones usually have better features however, don’t let the price fool you.

Believe it or not, some best products are at the normal price range. Hence, you should do some research to get the top rated product well-suited for your type of fishing or for your boat before making a purchase. With a little research on product-based reviews as well as customer reviews and voila, you will get all the information you need to understand your product.
