A Quick Shopping Tips – Best Trolling Motor Battery in 2022

When trolling for bass or other fish, you need a reliable motor battery to get you where you need to be. Here are some quick shopping tips for the best trolling motor battery:

Recharging:

You should never overcharge your battery. If you have a 12-volt battery, use a 12-volt charger. A 6-volt battery should use a 6-volt charger.

Lead Acid or Gel:

Lead-acid batteries are the most common type of battery and they come in flooded or sealed versions. Gel cells are a type of lead-acid battery that is sealed and will not spill.

Deep Cycle Battery or Starting:

A deep cycle battery is designed for sustained use, while a starting battery is designed for short bursts of high power.

Voltage:

The voltage of your battery should match the voltage of your trolling motor. Trolling boats 14 to 16 meters long should have a 12-volt battery, according to powerboat manufacturers.

For longer boats, a 24 or 36-volt motor is required. Each trolling motor will be equipped with a 12v AGM deep cycle battery that will provide low hours of power over a long period of time.

Size:

You should also consider the size of your battery. It needs to be large enough to handle the power requirements of your trolling motor, but not too large that it’s difficult to carry or store.

Lifespan:

The lifespan of your car batteries will also depend on how often you use them. A starting battery gets used daily, so the average lifespan isn’t as long as a deep cycle battery.

Cycles:

A cycle is one charge and discharge of your battery. If you use 20% of the power in each cycle, then the life of your battery will take about 5 years.

Durability:

Look for car batteries made from heavy-duty materials that resist corrosion.

Weight:

The battery should also be lightweight so you can easily move it around.

Warranty:

Most batteries come with a warranty, so be sure to check what is covered before you make your purchase.

When looking for the best trolling motor battery, it is important to consider the factors listed above. By taking into account the needs of your trolling motor, you can be sure to find a battery that is perfect for your needs.
