What Are Trolling Motor Batteries?

Trolling motor batteries are special batteries meant for boat use. The main purpose is that they are to provide power over an extended period. You may like fishing for hours; thus, the least you would want is a battery failure.

You may want to sneak up on some of the fish or for you need to cruise along. You may have been paddling for hours, and you just need to rest for a while. Well, the best trolling motor battery should make all this possible.

To better understand troll motor batteries and how you should decide on the right one, we will look at different factors to consider.

How to Pick the Best Trolling Motor Battery

Battery type

Batteries come in different types, but the two dominant troll batteries are lead-acid wet cell and absorbed glass mat (AGM) batteries. The former is cheaper but requires maintenance periodically. AGMs can be expensive; however, they require no maintenance and last longer.

Amp Hour Rating

This indicates the length of time a battery will sustain you at a given amperage. An example, a 100 amp-hour battery will provide 5 amps for about 20 hours. This is important information for those for long trips or who use trolling motors that draw a lot of amps.

Cold Cranking Amps

It is not quite the most important consideration for many people. However, it is important for those that work or fish in the cold regions. It will help you determine whether the battery will survive the cold conditions or its performance will be affected.

Weight

Some anglers do not mind carrying around a heavy battery. It will, however, inconvenience other people during installation. A lightweight battery will come in handy if you do not have the muscles. Also, the battery adds significant weight to your boat. Having a very heavy battery will imbalance your vessel.

Charging Time

If you like going on fishing trips frequently, you should opt for a battery that charges for a brief time. This is to avoid removing the battery when it is not fully charged. You will also avoid getting stranded in the waters.

In other instances, for those who only fish during weekends, charging time is not such a pressing matter. You will have a lot of time to recharge your battery.

Durability

It is quite common sense that durable batteries will last longer. So, you have to look out for features that make a battery durable. An AGM battery has its lead plates fully enclosed in a casing. This will eliminate leakages and damages as a result of vibrations or shocks.

AGM is pricey, but you get value for your money. Buying cheaper batteries will lead to higher costs because of maintenance and protection.

Maintenance

Wet cell batteries demand a lot of maintenance levels. You have to clean them, refill them with filtered water, and look out for signs of corrosion. All these are hustles that are not worth it. You should therefore go for AGM batteries that require no maintenance. Wet-cell batteries are affordable but end up expensive in the long run because of maintenance.

Size

It is crucial to have the right battery that matches your boat’s size. Is your boat large for this battery? This is the question to ask yourself. You will need extra space to feel comfortable and ensure the boat is not congested.

The larger boats have no problem with large batteries as they drain more power. You have the freedom to go for the largest trolling motor battery if you have enough room. Matching the boat’s size to the battery size will also make sure you are not stranded in the middle of anywhere.
