What To Look For The Best Battery For Bass Boat?  

There are various battery options for a bass boat in the market, offering different capacities and benefits that make it challenging for people to choose the best battery for their boat. However, if you know what features are required in a bass boat battery, the hunt becomes relatively easy! Therefore, we have put together a list of all the factors & things that may help you choose a bass boat battery.

Read your user manual.

Read the user manual carefully that comes along with the package to operate the battery efficiently. You can ask the vendor to provide you with the manual. It will help you understand the battery operations, its capacity, and other essential things.

Find the right size battery.

The recommended criteria to select the right battery size for a bass boat is the ratio of 5 pounds thrust per 200 pounds of boat’s gross weight. It means that you have to choose the battery size according to the weight of your boat. The wrong battery size might lead to some disaster. Usually, the best battery options are 12V, 24V, and 36V. If your boat is 16 feet longer or more, a battery with 24V would be needed.

Choose the battery with the right RC

Reserve minutes, aka reserve capacity of a bass boat battery, is the number of minutes that a fully charged battery can maintain to provide a load of 25 amps.  It is an important buying factor to pick the right bass boat battery. Typically such things are mentioned on the battery. So take a moment and read all these things very carefully.

Age of the Battery

Another essential thing to consider is the battery age. The age of the battery is the number of days since the battery is manufactured. Purchase a battery during the first three months after it is manufactured. A battery with an estimated age of 3 months is efficient and provides the best results.

Consider Battery CCA

Another criterion to select a starting or deep cycle marine battery is its CCA. CCA, aka cold-cranking amps, is a boat battery’s ability to start the boat motor/engine at cold temperature. A starting battery with a significant CCA rating is efficient and dynamic and can start almost all forms of typical motors.


For a fully charged battery to fall below 10.5 volts while discharging 25 amps, reserve power or RC is the length of time needed. At 80°F Temperature, RC is measured. A battery would be able to work longer with high reserve power.

Price of the Battery

Price always has been the primary deciding factor when buying anything. Hence, it is an essential factor to consider when purchasing a battery for your bass boat. Keep one thing in mind that an expensive battery is not always the best one. You have to find a battery that comes within your budget and provides all the features you want in the bass boat battery.

Care and Maintenance of the Battery

Outdated batteries with lead-acid require a lot of maintenance. The modern AGM (absorbent glass mat) lead-acid marine bass boat batteries are either maintenance-free or require low maintenance. It is because these batteries are leak-proof, allowing you a safe mounting any place you want.

How To Use And Setup The Bass Boat Battery Correctly?

Understanding how to use and set up the bass boat battery is crucial. The batteries undergo chemical reactions; therefore, always set them up very carefully. It is advised to use a tutorial and read the battery manual before putting one in the bass boat. Here is a checklist on how to use and set up the bass boat batteries:

Keep the Batteries Fully Charged

Even when the batteries are not used, you must keep them fully charged.

Make Sure That You Have a Breaker

When you install/setup a Bass Boat Battery, check that every trolling battery has a breaker. You can use a breaker with 50 amp power. Some bass boat batteries have a pre-installed breaker. That’s why you should check it first. In case your battery already has it, look for the negative and positive leads.

Attach the Negative & Positive Leads

If you are using multiple batteries, say three batteries, attach the positive lead of battery 2 with battery three and its negative charge to battery 1. Then take a pre-made jumper and hook the battery two positives with battery three negatives using the jumper. Take another jumper and attach it to battery one positive and battery two negatives. In short, you will make six connections for three batteries – one being the host, the other being the lead.

Install a Precision Charger with Four Banks

The batteries need to be charged all the time, which is you should install a charger with four banks. Label three of the banks according to the battery number and attach the batteries to the charger.

Is There A Difference Between Deep Cycle And Marine Battery?

Marine batteries have three types, including the deep cycle, dual-purpose, and a starting battery. Most marine batteries are a hybrid of a deep cycle and starting battery. You can find the batteries under a single name in the market, ‘Deep cycle marine battery’ for bass boats.

The hybrid marine batteries come with lead sponge plates. The sponge plates in a hybrid battery are heavier and coarser than a starting battery but thinner than the real deep cycle’s battery plates.

The deep cycle marine batteries come in handy when the boat engine is no longer in need of quick but powerful energy bursts. Deep cycle marine batteries provide the boat with reliable and continuous trolling power to run boat electronics like radios, sonar, and GPS.

The deep cycle marine battery, aka a trolling battery, comes in several designs. One of the critical designs of deep cycle batteries includes fewer but thicker plates. Unlike the other batteries, the deep cycle marine batteries have solid, not the sponge lead plates. The thicker plates provide continuous power output for the boat for a long duration. Unlike the cranking batteries, the deep cycle marine batteries can be recharged once they are fully drained.

There are three kinds of deep cycle batteries: the AGM deep cycle, gelled deep-cycle, and the industrial deep cycle battery. The life span of all three deep cycle batteries is different. The AGM deep cycle has a life span of four to eight years, gelled deep cycle with two to five years, and a deep industrial cycle can last up to ten to 20 years.

If we compare it with deep cycle marine batteries, the starting marine batteries deliver short but high-current bursts. It means that the batteries crank the boat engine by discharging a small part of their capacity frequently. A starting marine battery is often used for inboard and outboard marine engines. These batteries are of use to power a trolling motor. In contrast to deep cycle batteries, the marine starting batteries have an average life span of one to six years.

Marine Battery Take Care And Maintenance Tips

Proper cleaning:

  • It’s vital to use protection measures for the skin and eyes, including eye masks and latex gloves.
  • Mix a clean water solution of baking soda.
  • To apply the cleaning solution to the dirty areas, including wires, clamps, screws, and battery surface, use a wire brush. Scrub it gently until it loosens all the debris.
  • Go over surfaces to remove any remaining grime or dirt with a clean rag.

Knowing when to recharge:

A multimeter is one of the best devices that you can own. It helps you to monitor your battery’s energy level to know when it needs to be recharged. Between 13.0 and 13.2 volts is the optimal voltage range when it hits 12.55 volts or smaller, recharge.

How to charge:

  • Start with clean rust, grime, and moisture-free battery.
  • To ensure that they are not damaged or loose, check all wires, clamp screws, battery cases, and terminals.
  • Apply high-temperature grease to cable links and posts in a thin film.
  • In non-sealed batteries, inspect electrolyte levels. Fill it with distilled water if the level is below the splash barrel of the split ring. Do not overfill.
  • Use decriminalized water only—safe caps when achieved.
  • The battery charges in only a well-ventilated
  • Follow the guidelines of the manufacturer about charging times. It ranges from one battery to the next.
  • With the battery charger off, connect the battery posts with clamps.
  • Plugin the battery and turn it on. Enable it to charge until you have ultimately charged the battery.
  • Switch the charger off and unplug it.
  • Enable the battery to cool before service after charging.


Marine bass boat batteries are designed to deliver power solutions for your boats. While the starting battery is used for inboard and outboard engine power to start it, the deep cycle batteries can power the boat electronics and power trolling motor. If you own a boat or water vessel, you’ll need at least one type of marine battery. Keeping things separate with a starter and deep cycle battery is a standard installation, but if you have little room or lower power needs and want to save weight, a dual-purpose model could be your preferred choice.
