Why does my trolling motor take so long to run?
The higher the amp hours, or Reserve Capacity the longer it will run your trolling motor. Your battery will wear out over time. Age, poor maintenance, and over discharge will contribute to it no longer being able to deliver the rated amp hours. Keep that in mind when calculating the runtime.
How long do trolling motor batteries last?
It determines how long you want to run the trolling motor. As such, the longer you intend to run the motor, the more amp hours you’ll want your battery to have. For instance, if you have a motor that is designed to get 52 amps at full speed and you connect this to a battery rated at 50AH, it will last for 0.96 hours (50/52).
How many amps does a trolling motor draw?
We can estimate amp draw based off the pounds of thrust a trolling motor is rated for by rounding down to the nearest ten. For example: 46lbs of thrust roughly draws 40 amps. However, this is only true for 12V powered trolling motors.
Is it worth it to upgrade my trolling motor?
In addition trolling motors with a higher thrust rating tend to be more efficient and will have a lower amp draw for a given prop speed. So upgrading your trolling motor may add some significant time to your runtime.
How long will a 12 volt battery run a trolling motor?
Almost 5 hours doesn't seem too bad, but that is really a max runtime in ideal conditions. Reality is likely to be less. If the battery is old, damaged or not fully charged then you will not get the rated amp hours from it, reducing your runtime. Significant cold or hot weather will also reduce your runtime.
How long will a trolling motor run on a full battery?
The larger the rating, the more power the battery can hold, and the longer it will be able to power a motor at a given speed. For example, a 100 amperage hour battery is one that would be able to supply 25 amps of power for 4 hours (25 amps * 4 hours = 100 amp hours) before running out of energy.

Charge them after every trip. If it sits for longer than a week, charge them again. Your batteries should be charging everytime you run the boat. if you run every week, you probably won't ever need to run the charger as they should be fully charged when you return to port.
Can you run a trolling motor out of water?
Your motor is cooled by the water around it, while running it out of the water for a very short time would be OK, it would take a long time to drain the battery much running the motor out of the water with no load. Why risk damaging a very expensive TM to just drain the battery down.
Can you overcharge deep cycle battery?
Overcharging Deep Cycle Batteries: As a result of too high a charge voltage excessive current will flow into the battery, after reaching full charge, causing decomposition of water in the electrolyte and premature aging. At high rates of overcharge a battery will progressively heat up.
How to determine how long a motor will run on water?
In order to approximate how long a certain motor will run on the water, you simply take the battery's amp hour rating and divide it by the amperage draw.

They are also much more convenient as they allow you to dial in the speed to the exact setting you want vs. having to select from pre-set speeds.
The different batteries you could get
When it comes to picking batteries, there are mainly two options in the market. First, there are starter batteries. These are designed to discharge a large amount of current for a short period- somewhat similar to what a car battery does. This, however, is not ideal for use on a trolling motor since it could damage the battery and your motor.
Lead-acid batteries
Lead-acid batteries are very common and what most people settle for to power their trolling motors. The lead-acid batteries are designed to withstand the frequent recharging and draining that comes with their use on trolling motors. This makes them a worthy investment.
AMG Batteries
An alternative to the lead-acid batteries is the AMG variants. If you check the charge on this and a lead-acid variant, these tend to run longer as compared to their counterparts. Additionally, they are completely sealed which makes them safer to handle.
What about the amperage hour rating?
For you to measure the battery capacity, you’ll need to know the amp-hour rating of your battery. To make things easier, think of the amp-hour rating as being similar to the capacity of a gas tank of your car. It determines how long you want to run the trolling motor.
Something to bear in mind

Why does a motor shorten battery life?
Using a motor in strong currents, winds or heavy loads will shorten the battery life. Just as rowing a boat up stream is harder than downstream, when a motor encounters resistance, it will pull more current from the battery to overcome the additional resistance.
What is the amperage draw of a motor?
Amperage draw describes the amount of electricity the motor pulls from the battery to power itself. A motor pulls different amounts of amps depending on the speed it is operating at and if there is any resistance applied to the motor. This information should be provided by the manufacturer and should be readily available on the product listing or on a specification sheet for the motor. However, only the max amperage draw will typically be listed - this is the amount current the motor pulls from the battery at top speed.
