If you are an avid fisherman than you know the importance of having a solid and stable trolling motor battery.  Being on the water and having your trolling motor battery start to die is a very frustrating feeling especially if you’re in a tournament and all you need is that lunker to put you over.

I’m an avid bass fisherman and fishing the Colorado river demands having the right trolling motor battery to pull the current, so I know a thing or two about trolling motor batteries.

Depending on your conditions you may want to run your deep cycle battery side by side in series with another deep cycle marine battery. This will allow you to run a 24 volt system that is more powerful and more efficient.  If you main body of water is a river than this is a must for being able to handle the current.  As long as your boat has the room you should have no problem wiring up your trolling motor deep cycle battery to a 24v system.  The down fall for this system is that will cost you double to provide a trolling power to your boat.  But, there is way more upside than down side.  Invest the money and you will be glad you did.

Another aspect of a good trolling motor battery is the brand.  Believe it or not you get what you bay for with deep cycle batteries. The most popular place to buy a marine batter is at Wal-Mart.  This should be avoided a trolling motor battery from Walmart might not be the quality you’re looking for.  They carry Everstart MAXX valve regulated lead batteries which will have not have the longevity of a quality flooded cell lead acid battery.  These type of batteries can be refilled with electrolyte  and will tend to have a longer life…up to 4-5 years. The key is quality brands like Trojan, Exide, Optima, Crown and Glentronics are all good quality batteries. With quality comes price and the initial cost of a quality trolling motor marine battery will keep you on the water longer…which is what you want…right?

Last but not least is trolling motor batter maintenance.  Maintaining your battery will save you time and money.  A couple of tips that will have your deep cycle battery ready for action:

  • Buying a three stage charger that will bulk charge, absorption charge and float charge will give your trolling motor battery a nice and even charge then be able to maintain that charge using the trickle charging voltage.  Basically these chargers will step down the amperage as the charge in the trolling motor battery get’s to capacity.
  • Using a voltmeter be sure your battery is holding a charge of 12.7v or around 2.15 per cell
  • Depending on your level of knowledge on deep cycle batteries always use a Hydrometer over a volt meter as you will be able to get a more accurate reading (this is not all the important, but recommended)
  • Only use clean water to clean your battery. Avoid chemicals and any other type of battery cleaning chemicals
  • Use your battery often. The most damaging element to a trolling motor battery is having it sit on the shelf or in your boat.  A typical deep cycle battery will need at least 10-20 dischargers to get at full capacity.

One last thing about purchasing a trolling motor battery.  Shop online as there are many online retailers that have trolling motor battery sales all the time.  Some may even include free shipping that will be just like going to your local battery shop.

In future post I will review some of the batteries that I use.
