Choosing a Trolling Motor Battery

Trolling batteries are not just any kind of battery, and there are some things that you will want to consider certain factors, including your budget, the hour rating and the battery type.

Type of battery

12-volt deep cycle batteries come in two types – AGM batteries and Lead Acid Wet cells. Deep cycle batteries are very good for trolling because they discharge lower amounts of current, spread out over longer periods and recharging more frequently.

Lead acid wet cell batteries are more common compared to AGM batteries, since they can handle more frequent drains and recharging that comes with using trolling motors, and in addition they are the most affordable option for most. Their life lasts for about three years and are standard in their structure. The only drawback about them is that they need more occasional maintenance, which involves topping off the water. They are also vulnerable to spillage and vibration issues.

The second option is the AGM batteries, which means Absorbed Glass Mat. These are sealed completely, and are more long lasting compared to wet cells. They last for averages of up to four years, but the drawback is that they cost significantly higher than wet cell batteries. In fact they can even cost twice as much, so they are not an option if you are on a tight budget. In spite of them being expensive, they have no maintenance costs, and are very good for performance and long life.

Power hour ratings

The amperage power ratings of your battery are similar to those of car gas tanks. If you consider all factors to be equal, batteries that have 115 amp hour ratings last for longer periods than 100 amp hour ratings. When you look at the technical aspects, 100 amp power batteries provide 100 amp hours of current in trolling motors. So technically, if your motor runs on a speed of 5 amps, for example, the battery should theoretically last for 20 hours. The higher the speed of your motor, the less time the battery lasts.

When searching for trolling motor batteries, look for those that have at least 100 amp hour rating, 175 minutes of Reserve Capacity (RC), and a Group 27 rating.

Final Remarks and Recommendations

You need a good trolling motor. It is not an issue to be assumed or dismissed as less important. A dependable trolling motor battery ensures smooth and maximum performance of your boat. Anytime you go out fishing or a ride on the lake, the battery plays a bigger part than assumed. Similar to majority of electric devices and motors, trolling motors too require specific batteries. Batteries that will boost the trolling motor’s performance. Batteries that will discharge electricity steadily over the prolonged period of that fishing trip. The optimal battery 8016-103 D34MBlueTop would be a great choice. With all its lasted features, the battery is bound to perform to your expectations. It can recharge up to 1000 times and it is still proof. It is also resistant to vibration. This battery would be a great choice for your trolling motor. And for the love of god… would you please wear your life vest while fishing.
