The Best Trolling Motor Battery in the Market
The battery is the most vital part of a trolling motor. A trolling motor would not work without a battery. It supplies the required power to the trolling motor. If one loves fishing, one must always buy the best battery for the trolling motor.
Trolling motor batteries are fully rechargeable. Some important factors must be considered when buying a battery for the trolling motor.
- Type of battery
- Amp-hour ratings
- Vibration Resistance
- Thrust of trolling motor
- Fishing conditions
- Boat weight and size
- Weather conditions
- Price of the battery
- Volt system of trolling motor
Type of battery
Batteries for trolling motors are designed differently specially for the trolling motor use. One cannot just use any type of battery for running a trolling motor. For trolling motor, the mostly used and preferred batteries are the AGM batteries and the marine wet acid batteries.
Flooded or wet acid batteries are designed especially for trolling motor use, deep discharging and recharging. These batteries last for two to two and half years and are cheap in cost. One can purchase a flooded deep cycle standard battery for 100$, which is an ideal deal for that much use.
AGM batteries are not flooded type. These batteries contain absorbed glass mat between the plates and the battery is not filled with liquid acid, which make it different from a standard wet cell deep cycle marine batteries. The lives of the AGM batteries are longer than that of the wet acid batteries that are the batteries live for three to four years. The AGM batteries are costly, but it can be considered as these batteries don’t require extra maintenance or service and don’t have the risks of acid leaking or gas leak. If one has a high budget, then an AGM battery is the best choice for a trolling motor. However, deep cycle batteries are the best batteries for a trolling motor.
Before getting a battery for trolling, one must look for the amp-hour rating that is written at the sole of the battery. if the amp-hour rate of the battery is given 200 amp-hour, the battery will give 200 amp-hour, say one is running a trolling motor in a low speed and using 5 amps, than the battery will last for 40 hours, but if one is running the battery in full speed and using 50 amps, than the battery will last 4 hours. An ideal battery for the trolling motor must have at least 100 amp-hour rating. The more is the rating, the longer will the battery run.
While running an engine boat as well as the trolling motor, it is obvious that the base of the boat is going to vibrate, so is the battery going to vibrate too. The battery has plates placed in a specific manner, and the plates decide the life of a particular battery. When the battery is prone to vibration and regularly gets this, the plates inside the battery get displaced and slowly the battery starts getting damaged, the battery becomes unable to hold that much charge like it did earlier, the battery will get heated very fast and definitely make the battery dead and there will be the need to get a new battery. So one must always go for the trolling motor battery that is resistant to vibration and are designed in a special manner to face the vibrations, else the battery won’t last long, no matter what the cost or the estimated lifespan is.
For the wet acid cell or the flooded batteries, spilling and leaking of the acids is a very common and concerning problem. The acids might spill and may cause a permanent damage to the boat in which the trolling motor is mounted, or it may also damage the wires that connect the trolling motor, and can also hurt the person who is handling the batteries. In the modern market with the advanced technologies, new things are being invented and innovated. Some flooded batteries come with sealed cases that are spill proof and some are sealed with in the batteries, like the gelled batteries. So in case, one is buying a flooded battery, the battery must be completely sealed and must be spill proof.
Thrust of trolling motor
Thrust of a trolling motor is very important in a trolling motor. Thrust is the power in other words. So, the power required from the battery depends on the thrust the trolling motor needs. If more thrust is needed then the amp-hour rating should be more.
One can fish in two conditions usually, shallow water and deep water. For shallow water, the power is not required much, but in deep water fishing, the power requirement is high and one must also keep in mind that due to battery shortage one doesn’t get stuck in the middle of the more water. So it is best to select a battery for trolling motor that has a high amperage hour rating.
Boat weight and size
Boat weight and size is one important factor to be noted while selecting a battery for trolling motor. The more is the size of the boat, the more thrust is needed and so is the power, but this doesn’t mean that the battery needs to be heavy and large.
One must measure the space on the boat for the battery, if there is no much space then one must buy a small size battery. If the boat is already heavy, one would not want to add an extra heavy weight to the boat, as it could slow down the speed of the boat.
AGM batteries are not a good choice for small size boats with less space, as this type of batteries requires permanent mounting on the boat. So it is no use if the mounting is not possible. For small size boats standard deep cycle marine batteries are the best.
The conditions of weather are a necessary condition to be considered. The water and the weather can very possibly affect the performance and the run time of the battery. A trolling motor that draws 30 amps at a normal speed in a good weather condition may draw 40 amperages in a bad and stormy weather for the same applied speed on the same boat. So if one has plans to fish regularly on the stormy weather conditions, then this factor must also be calculated before buying a battery for trolling motor, else it might create an unwanted issue in the business.
Volt system of trolling motor
Volt system is one of the most important factors that decide the battery needed. In a trolling motor with 12 volt system, only one battery is required, but for higher thrusts, volt systems increases, like 24 volt system, 36 volt system and so on. Now, with the increasing volt systems, the number of batteries also increases, for 24 volt system, two 12 volt batteries are required and for 36 volt system, three 12 volt batteries are required. One can use a 12 volt battery in a 24 volt system; one would not get the desired power and the thrust, so it is better to go by the rules as it might also damage the trolling motor system.
It is best to buy the same type of batteries for a single trolling motor, and should never connect the old and the new batteries in the same circuit. The negative terminal of a battery should always be connected to the positive terminal of the other battery. One should never connect the positive to the positive or the negative to the negative, as it will cause damage to the motor. Simple rules must be remembered and followed if one doesn’t want to lose the life of the battery before time.
Price of the battery
Price or cost of the battery is an important factor. It is not true that cheap is good, the truth is, cheap can be disastrous as these batteries could leak acids and gas that might cause damage to the boat. In the other hand, too much expensive is also not good. The cost must be medium and must give a sufficient result and lifespan. A premium battery costing 100$ is a perfect choice as it may be costly but has a long durability and power, which worth the cost.
Considering all of the factors, before getting a battery, one must be sure about maintaining the battery;
- The batteries must be charged after every use, as leaving the batteries simply in discharged conditions will decrease the life span as well as the performance of the battery.
- In case the battery is a flooded type, the water level must be regularly checked as if the water dries out, the battery might die.
- The terminals must be cleaned and checked for corrosion.
- During off seasons, when there is no use of the trolling motor and the battery needs to be sat for a long time, the battery must be placed at a dry and cool place and must be charged at times.
One should look for the best and buy even better than the best. A good research is very necessary before getting a battery for the trolling motor.
