How to Charge a Trolling Motor Battery: Easy Guide for Maintaining Your Trolling Motor

If you’ve never used a trolling motor before, you may be unsure how to care for one. From how to charge a trolling motor battery to clean the battery connections, we’ll cover everything here. Trolling motor batteries come in a variety of varieties, so we’ll go through how to charge a trolling motor battery with some helpful tips and tricks in our discussion. This piece offers something for you, no matter how long or how little experience you have with trolling motors.

Trolling Motor

An outboard motor is quite similar to a trolling motor. It’s a complete package with an engine and propellers. The key distinction is that trolling motors are significantly smaller and are intended for use with smaller boats. They’re also electric, meaning they’re powered by batteries.

Anglers love trolling motors because they enable them to fish in places where an outboard motor would be impossible to reach. A trolling motor, for example, may be used to fish in shallow water or around docks and other obstructions.

Different Types of Batteries

There are different types of batteries used in trolling motors:

AGM Batteries

Absorbent Glass Mat (AGM) batteries are lead-acid batteries that utilize AGM technology. AGM batteries have the benefit of being more vibration and shock resistant than standard lead-acid batteries. The most common form of battery used in trolling motors is an AGM battery. They don’t need any care and have a lengthy lifespan. They’re also less prone to leak, which makes them ideal for trolling motors.

Gel Batteries

The electrolyte in gel batteries is an alternative to liquid electrolytes. Gel batteries have the benefit of having a lower leakage rate than standard lead-acid battery types. Trolling motors benefit from the fact that they are more resistant to vibration and shock. While AGM batteries utilize a glass mat to absorb water, gel batteries employ a gel instead. The gel acts as a barrier to keep the battery safe.

Batteries with Wet Cells

The first rechargeable battery was a wet cell battery. Aviation, electric utilities, energy storage, and mobile phone towers are all popular places to find it. Lead-acid batteries with wet cells are the most prevalent. Electrolytes in liquid form are referred to as “wet cells” since they are used. As a result of their lower cost, wet cells are a more cost-effective option for lead-acid batteries.

Lithium Batteries

Lithium batteries are different from lead-acid batteries in that they employ lithium instead of lead. It has the benefit of being significantly lighter than lead-acid batteries. They’re also more vibration and shock-resistant, making them an excellent option for trolling motors.

Trolling Motor Batteries Durability

On a single charge, the typical trolling motor will operate for roughly three hours. If you plan on utilizing your trolling motor for extended periods of time, you might consider upgrading to a larger battery. When it comes to how long your trolling motor battery will survive, there are no hard and fast rules. It depends on the battery you have, how well you manage it, and a variety of other aspects.

The Most Effective Way to Charge a Trolling Motor Battery

A smart charger is a gadget that charges your battery by plugging it into an AC socket. Overcharging is prevented by the automatic shut-off mechanism included on most battery chargers. Battery chargers made exclusively for trolling motor batteries are available. These chargers will be set up to charge and maintain your battery properly.

Follow these instructions when you’re ready to charge your trolling motor battery:

  • Start by disconnecting the power supply from the motor.
  • Inspect the battery for leaks or damage.
  • Ensure that the terminals of the battery are clean.
  • Connect the positive (red) line from the charger to the battery’s positive connector.
  • Connect the negative (black) wire from the charger to the battery’s negative terminal.
  • Set the charger’s mode to “trickle charge” or “maintain.”
  • Activate the charger and let it operate until the battery is fully charged.
  • Turn off the charger and unhook the leads after the battery is completely charged.
  • Re-attach the battery’s lid.
  • Re-attach the trolling motor’s power source.

Common Question (FAQs)

Do boat engines charge batteries while they are running?

The alternator on most boat engines charges the batteries while the engine is operating. It’s always a good idea to double-check your owner’s manual, however. A unique charging mechanism may be required for certain engines. The battery will charge when the boat is idling, but this is a somewhat inefficient method of charging the battery since the alternator must drive all of the electronics before charging the battery, so there isn’t much additional power source while idling, but there is some.

Can I use a car battery charger to charge my trolling motor battery?

Yes, you can charge your trolling motor battery using a vehicle battery charger. If you’re in a rush and don’t have access to a specialist trolling motor charger for batteries, you should use this method. Unlike trolling motor battery chargers, automobile battery chargers are meant to charge car batteries. Because trolling motor batteries need to be charged at a slower pace in the battery charging process, using a vehicle portable battery charger might harm the battery.

What is the difference between a fully automatic and manual battery charger?

When the battery is completely charged, fully automated chargers are meant to switch off automatically. Overcharging, which may harm the battery, is avoided. When the battery is completely charged, you must manually turn off the charger using a manual charger.

How long does it take to charge a trolling motor battery?

The size of the battery or battery power and the kind of charger you’re using will determine this. In around eight hours, a normal 12-volt battery may be completely charged. The battery, on the other hand, maybe completely charged in as little as two hours if you use a fast charger.

What is the best way to store a trolling motor battery?

A trolling motor battery should be kept in a cool, dry location. Even if you’re not using the trolling motor, you should keep the battery charged. Finally, charge and store the battery according to the manufacturer’s recommendations.

Do solar chargers work in cloudy conditions?

Solar chargers function in overcast settings, although they are less efficient than in bright sunlight. It’s preferable to charge your trolling motor battery using a solar charger while the weather is sunny.

What exactly is a deep cycle battery?

A deep cycle battery is a kind of battery that may be recharged and drained repeatedly without causing any harm to the battery itself. A trolling motor’s battery is a deep cycle battery, which is intended for heavy-duty operation.

How to disconnect a boat battery?

As a boat owner, you should know how to remove the boat battery. For your safety and the safety of your boat’s electrical system, you should install a grounding system.

Turn off all of your boat’s lights and equipment before disconnecting a battery. Then identify the battery’s negative terminal. The “-” symbol is often used to identify the negative terminal. To complete the procedure, remove the battery’s negative lead. You may securely remove the battery from your boat after the negative connector has been unplugged.

Once you have connected the solar panel to your trolling motor battery, you can begin charging it with solar power. Place it in an area that gets a lot of sunlight. As long as the solar panel is in a sunny place, the battery will be charged by the sun. Afterward, unplug the solar panel from the battery to finish charging the battery to full capacity.

Can I charge the trolling motor batteries using the engine alternator?

Yes, you may use the engine alternator to charge the batteries in your trolling motor. However, charging trolling motor batteries, the battery should not be done while the engine is running. Damage to the battery and a shorter life lifetime might result from this.

To use the engine alternator to recharge the battery, first, remove the negative battery connector. Wait a few minutes before restarting the engine. Reconnect the battery’s negative terminal at this point. As long as the engine is running, the alternator will keep the battery charged.
