What batteries are best for an 80-pound thrust trolling motor?

For an 80-pound thrust trolling motor, you'll need to use two 12-volt deep cycle marine batteries connected in series for a total of 24 volts. Deep cycle batteries are designed to provide continuous power output for an extended period and can be discharged and recharged multiple times without any damage. Popular deep cycle battery types include AGM (Absorbed Glass Mat) and Gel batteries.

How do you connect batteries for a 24-volt trolling motor setup?

To achieve a 24-volt setup for your trolling motor, you'll need to connect two 12-volt deep cycle marine batteries in series. To do this, follow these steps:

  1. Place the two batteries in a secure and ventilated compartment in your boat.
  2. Connect the positive terminal (+) of the first battery to the negative terminal (-) of the second battery using a battery cable.
  3. Then, connect the trolling motor's positive cable to the positive terminal (+) of the first battery, and the motor's negative cable to the negative terminal (-) of the second battery.

Now, your trolling motor will be powered by a 24-volt battery system.

How do you maintain and extend the life of deep cycle marine batteries?

Taking care of your deep cycle marine batteries is essential for their longevity and performance. Here are some tips to help you maintain your batteries and get the best out of them:

  1. Regularly check and maintain the battery's water levels: Ensure that the water levels are above the plates, especially for flooded lead-acid batteries. Use distilled water to top up, if necessary.
  2. Clean the battery terminals: Inspect the battery terminals for corrosion and dirt, and clean them using a wire brush and mild baking soda solution to maintain good electrical conductivity.
  3. Keep the battery fully charged: Regularly recharge the battery to avoid deep discharging and extend its lifespan. Use a high-quality battery charger with multistage charging to ensure the battery’s health.
  4. Store the battery properly: If you plan to store your batteries for an extended period, ensure they're fully charged and kept in a cool, dry, and well-ventilated space.

When should you replace your trolling motor battery?

Deep cycle marine batteries will naturally degrade over time, and their performance will decline as they age. Here are some signs that your trolling motor battery may need replacement:

  1. Shorter runtime: If your battery is not giving you the same runtime as it used to, even when fully charged, it may be a sign that its capacity has diminished.
  2. Difficulty in charging: If your battery experiences trouble in accepting a charge or takes much longer to charge than usual, it could be due for a replacement.
  3. Visual inspection: Look for any cracks, swelling, or leakage around the battery's casing. If you notice any of these signs, it's time to replace your battery.

Remember, keeping an eye on your battery's performance and maintaining it properly will help ensure smooth operation of your trolling motor and extend the life of your deep cycle marine batteries.
