How to Choose the Best Trolling Motor Battery Buyers Guide
When selecting a motor battery there are three factors to consider; durability, peak power draw and maintenance. These specifications play a role, in ensuring that you acquire a motor that performs well and has a long lifespan. Additionally it is essential to choose the voltage, for your boat and understand the significance of having power output.
One significant aspect to keep in mind is the durability of the trolling motor battery. It should be able to withstand speeds and heavy loads without weakening or faltering over time.These components can often be put under a lot of strain. It’s advisable to look for one that is designed to handle power demands and is resistant, to vibrations. This ensures that the batteries can endure conditions and remain durable enough to last through fishing trips without malfunctioning prematurely.
Peak Power Draw refers to the amount of current (measured in amps) used by the trolling motor. It’s crucial to select a battery with power output because if this value is too low the motor will only be able to maintain a speed and may eventually shut down during prolonged use. On the hand a battery with draw can lead to difficulties when attempting high speed turns due to insufficient torque.
Maintenance plays a role in choosing motor batteries as they can be sensitive to issues such, as over discharge or faulty charging systems. It is essential to use a charger that matches the specifications of the battery and regularly inspect for signs of failure or sulfur buildup which should be promptly cleaned from ports and terminals. Experts strongly advise against leaving a battery in a discharged state for periods of time.Weight; On average trolling motor batteries typically weigh, between 6 and 12 pounds. So if you want to carry it around it’s crucial to find one with a design. Smaller batteries that are well balanced can be conveniently carried by the operator whereas larger models might require lifting tackle or other equipment to lift and handle.
Run Time; Run time refers to the duration until the battery needs recharging. Generally run times are preferred because they tend to last. However it’s important to consider power draw when making a decision. Smaller batteries are commonly used on boats. Have shorter run times compared to larger batteries that are often suitable for larger watercraft.
Lifespan; Lifespan indicates the number of cycles. Recharges a battery can endure before its performance starts deteriorating. Larger batteries usually have lifespans than ones but this doesn’t mean that size should be completely ignored. It’s essential to choose a battery that can last a time without experiencing excessive deterioration or damage due, to misuse.
Vibration Resistance; When selecting a motor battery it’s important to consider its vibration resistance as it directly affects its longevity.
It is advisable to place batteries in cases or dedicated holders to prevent any damage. If possible avoid storing batteries in areas where they are directly exposed to wind and waves as this can cause them to shake and endure impact.
The size of the battery is a factor as it determines its dimensions and can significantly impact the weight of the boat. Larger boats typically require batteries, which tend to be heavier. Therefore when selecting a motor battery it is crucial to consider finding a balance, between size and weight. This ensures that you have equipment that lasts longer without becoming too burdensome for the operator.
Recharging is essential, for every motor battery. There are several available methods. You can use battery chargers that plug into outlets install panels on your boat for direct battery recharging or opt for portable rechargers that you can take with you wherever you go. It’s important to select a charging method that fits your budget and works effectively in your setup.
Electric trolling motors operate by utilizing a generator to power a propeller assembly consisting of blades. These motors generate thrust by using electricity stored in batteries to rotate the propeller.
This technique is commonly employed when fishing in waters using moving boats and is also popular, as a source of entertainment while engaging in activities like waterskiing or tubing behind a boat.
These motors come equipped with individual control panels that allow for the propeller to rotate at speeds while enabling levels of thrust to be generated. They can be tilted upwards or downwards to control the position of the propeller assembly and steer the boat accordingly. More recent models have adopted power eliminating the need for onboard power storage. This makes them significantly lighter and easier to maneuver compared to trolling motor batteries.
Step Up/Down Converters
Step up converters are used to convert voltage (12V) into voltage (120V) whereas step down converters serve the purpose of converting high voltage (120V) into low voltage (12V). These converters are essential, for applications where AC current’s not readily available. It’s advisable to keep a converter handy as most solar panels come with one that may require replacement if damaged. In case of damage the converter can be replaced with either the type or its opposite counterpart.
A single converter that can either step up or step down the voltage can be utilized in two ways. For example you can use a 12 volt converter to step up the voltage or a 220 volt converter to step it down.

Best Trolling Motor Battery Tips
it’s important to understand that the size of a battery doesn’t determine its output or capacity. When it comes to deep cycle batteries, their power and energy capability are measured in hours (Ah) not dimensions. For instance a battery with an Ah rating of 100 can provide much power as one rated at 50 Ah. Typically deep cycle lead acid batteries for boats have an Ah rating ranging from 80 to 100.
To determine the ampere requirement for your boats systems consider the amp draw from the engine alternator. To calculate the amp/hour rating of your battery accurately subtract 10% from the number displayed on its label. For example if you read 100 amps on your battery label deducting 10% (which’s equivalent, to 40 amps) and dividing that number by 2 will give you an estimate of how Ahs you should aim for to ensure sufficient power throughout the day.
Assuming you’re using high quality batteries, like Kirkland lithium batteries or the ones I use in my boat and truck here are some tips for maintaining your trolling motor battery;
Regular maintenance involves changing the electrolytes every month or so and adding water when necessary. Make sure to change them at a month especially during hot weather and in saltwater conditions. Don’t forget to clean and inspect the battery terminals for any corrosion. Of using a wire brush on the battery posts it’s better to use a cloth to wipe any corrosion or protective coating.
When it comes to charging maintenance always remember to turn off the charger before removing the battery from your boat or RV. Avoid overcharging your batteries as it can be detrimental. It’s generally a practice to disconnect your batteries after each use and store them separately when not being charged. This helps extend their lifespan while allowing for rotation between them.
Here are some additional tips for maintaining motor batteries; If a battery remains unused for, than six months make sure to check its water levels monthly and add water if needed to prevent sulfation.
If you have a number of batteries stored make sure to mark the date of the usage directly on each battery using a permanent marker. This way you can easily keep track of when maintenance’s needed. To determine if your battery requires water, a simple and inexpensive hydrometer can be used. Just check if it floats in the electrolyte and take note of the reading. If month the hydrometer shows than 1.25 volts it’s likely that your battery needs water. Otherwise you can let them sit until spring. Remember that a little maintenance goes a way.
Optimizing Trolling Motor Battery Run Time
When operating your boats motor or motor controller it’s crucial to select the battery settings for your specific application in order to maximize run time. Most trolling motor controllers offer a dual battery configuration option that automatically shuts down if both batteries reach levels of charge. Before enabling automatic shut down ensure that you set the controllers output to its setting so as to extend each batterys time as much, as possible. If you are using two batteries in parallel and intend to utilize them at performance (without any load) then set your controllers setting between 20 and 30 amps, per battery in order to prolong their lifespan.
Choosing the Right Battery, for Your Trolling Motor
When it comes to selecting a motor system there are options and brands available. The quality of your motor depends on factors; the type of motor (outboard, inboard, stern drive) the desired size (such as foot control or helm) and the type of boat you have. The first thing to consider is whether you intend to use a heavy lift propeller or not. For boats using a heavy lift propeller at speeds while charging the batteries for extended periods like during a weekend outing can boost power significantly. Alternatively you can opt for a propeller. Charge the batteries daily over a weekend.
Trolling Motor Battery and Setup
To properly calibrate your motor it’s important to know the exact amperage load that your motor will draw. This information will help you set the current on your motor controller to achieve the desired power output. The best way to determine this is by ensuring that your battery is fully charged and then connecting either a fish finder, with data display or a digital panel ammeter directly to your battery terminals.
Now go ahead. Activate the trolling motor and retract the boats anchor (or operate the boats windlass).

Recharge the battery approximately every three months. If you’re not using the battery all allow it to fully discharge until there is no remaining charge.
The duration for which a deep cycle battery retains its charge relies on how you maintain it. If you aren’t using the battery it should hold its charge for three months.
If you use the battery frequently it should last for two weeks. Typically this type of battery has a lifespan of, around four years although this duration can vary based on how you handle and care for them.
When it comes to disposing of a deep cycle marine battery you cannot simply throw them in the garbage due to their acid content. Before discarding them make sure they are completely drained and remove all the caps.
Why are deep cycle batteries considered ideal for trolling motors? Well these batteries are specifically designed to handle repeated discharges of their capacity. When the engine is not running a trolling motor draws an amount of current from the battery to power electronics like lights and sonar units. This continues until the battery is almost depleted ( leaving 10% charge). At that point it switches to “float mode,” which uses current while maintaining voltage to prevent that bit from draining completely as it recharges.
What is the typical amperage drawn by trolling motors? On average trolling motors draw, between 3 and 7 amps.
How long can a trolling motor operate on a deep cycle battery?
Its not recommended to use discharged batteries for periods, such, as long fishing trips. If the motor stops you won’t be able to start it until the battery recharges. Therefore you’ll need to bring the boat to land and recharge the battery. If you let the battery run low it’ll be difficult to get it started again.
What type of charger should I use for AGM motor batteries?
The ideal charger is a charging system. These systems are designed to charge your trolling motor battery precisely as it requires. Won’t overcharge it like some chargers might do. They work well with both AGM batteries and wet cell batteries.
How significant is a Battery Warranty?
Most batteries come with a warranty, around 1 year. While there are warranties they usually don’t apply to trolling motor batteries. These batteries can endure at twice much abuse as regular 12 Volt car or truck batteries. They require maintenance and water testing compared to regular car or truck batteries. If your battery has a warranty of, than 1 year you might want to consider getting a lasting battery with an extended warranty.
How can I determine the group size of my batteries?
Typically most batteries have markings, on their bottom indicating their type, such as AGM or GEL. These acronyms stand for “Absorbed Glass Mat”. Gelled electrolyte,” which refer to the electrolyte used in each battery. Additionally batteries are assigned a number or code consisting of 3 or 4 digits, including letters. The first letter in this code indicates the batterys size. If you have a battery simply check its code. If it matches you’re looking at the correct group size. It is crucial to match both batteries in a set to ensure performance and cycle life.
Is it worthwhile to invest in AGM batteries of Wet Cell ones?
Absolutely! AGM batteries utilize glass mats to contain acid within them. These mats differ from lead acid batteries as they are crafted from a blend of glass that offers resistance against breakage.
What options do I have when it comes to selecting battery types?
The market today offers variants of AGM Batteries, some, with warranty periods compared to others.
The Wet Cell is the used AGM battery type and it offers a 1 year warranty, along with excellent cycling capability. However it falls short when it comes to long term storage compared to AGM batteries, with levels of wet or absorbed electrolytes.
