What Size Battery Do I Need For My Trolling Motor

In that location are a few things to take into account when selecting a trolling motor battery for your needs: Type of battery, amperage 60 minutes rating, and budget.

What kind of battery do I demand for my trolling motor?
- You need a Deep Bike or Marine Bombardment.
What are the unlike kinds of Deep Bike Batteries?
- Sealed AGM batteries and Pb Acrid Wet Cell batteries
Volition my car battery work for my trolling motor?
- No, car batteries are non recommended and can ruin your motor.
What's the cheapest selection?
- Pb Acrid Wet Cell batteries are the most affordable option for your trolling motor. We often recommend this 35ah bombardment, this 55ah bombardment, this 70ah battery, or this 100ah battery on Amazon.

Deep Cycle vs Starter Batteries:

Nearly consumers are familiar with large and heavy car batteries, simply there are actually two types of batteries that fit this description: starter batteries and deep cycle batteries. Deep-cycle batteries are designed for discharging pocket-sized amounts of current over a long catamenia of time (ex. running a trolling motor for hours). On the other manus, starter batteries are designed to discharge a large current for a short amount of time (ex. starting a motorcar engine). Starter batteries are not designed to constantly have their accuse dropped below 50%, only to exist recharged over and over. With this type of employ, starter batteries will not last very long. Regularly using a starter battery with a trolling motor can ruin both the battery and even the motor.

At that place are ii types of deep-wheel 12-volt batteries that are recommended for electric trolling motor use: Atomic number 82 Acid Moisture-Cell & AGM batteries.

Wet Cell vs AGM:

Lead Acid Wet-Cell: Lead Acid Wet-Cell batteries are the virtually common and affordable pick for trolling motors, and usually last near 2-3 years. They ordinarily cost less than $100 but are susceptible to vibrations and spillage, additionally they do require some maintenance.

Wet-Cell refers to the cells/plates in the battery being "flooded" or submerged in an electrolyte fluid, a mix of h2o and sulfuric acid. If the bombardment is overcharged too frequently, the h2o level will drib, to maintain proper water level, occasional superlative offs with distilled h2o are necessary. If the electrolyte level drops enough to expose the cells and plates, the battery can exist damaged and shorten the usable life of the bombardment.

Recommendation: Check the electrolyte level earlier each use, top off as necessary.

AGM Batteries: AGM batteries are newer than their Moisture-Cell counterparts, they are completely sealed, maintain their charge longer, and have a longer usable lifespan. AGM batteries are sealed and therefore do not require maintenance; with a reliable life as long as four years, they come at a higher toll than equivalent Moisture-Cell units.

AGM stands for Captivated Glass Mat and are also referred to as a Valve-Regulated Lead-Acrid Bombardment (VRLA) or Sealed Lead-Acid (SLA) battery. Dissimilar Moisture-Jail cell units, the electrolytes are held in glass mats instead of fluid, these glass mats are made up of very sparse drinking glass fibers that are woven into a mat to maximize the surface area. This increase in surface area is enough to hold electrolytes on the cells for their lifetime, making the battery lighter, spill proof, and less susceptible to vibration damage.

Amp Hour Rating determines how long you volition be able to run the motor, it is the bodily corporeality of accuse the battery can store. The longer you desire to run your trolling motor, the more than amp hours you demand.

A more technical definition is the amount of charge in a bombardment that will allow one ampere of current to menstruum for one hr and how much energy tin can be stored past the bombardment itself. For example, an fourscore AH battery will be able to discharge 100 amp hours of current to a trolling motor and will last longer than a 50 AH battery. Simple math will exist able to determine how long a motor volition run with a given battery. If a trolling motor pulls 52 amps at full speed while connected to a 50 AH bombardment, the battery will terminal about 0.96 hours. (50 AH bombardment / 52 amps drawn = 0.96 hours). More than information can be establish on our Computing Trolling Motor Run Fourth dimension folio.

Choosing the correct battery amperage hour rating depends entirely on the intended apply. Using a Newport Vessels 55lb thrust motor continuously for two hours at full speed would require a battery with a 100-120 AH rating. On the flip side, 2 hours at lower speeds with breaks volition just require a battery between 50-100 AH rating. Past using the equation above, an estimate can be made to determine the battery that will best fit your needs.

Of import Tips:

Do not mix battery types or ages.
Accuse the bombardment immediately later each use.
Shop the battery charged.
Check the fluid level of Lead Acid Wet-Jail cell batteries regularly and top off with water when necessary.
Cheque final connections for signs of corrosion, which increases resistance and lowers the ability output of a motor.
Clean any corrosion with blistering soda and toothpaste.
Store batteries in absurd nighttime identify connected to a trickle charger to avert completely draining the battery.
Employ in combination with our Smart Bombardment Box to get the most out of your trolling motor battery.
