How to Care for Your Trolling Motor Battery – Step by Step Guide
Even the best battery won’t perform to its specifications if it is not properly cared for. Here are some tips to help your battery lasts as long as possible:
Always keep it fully charged
As soon as you make it to shore, get the charger on your battery and keep it full. A Battery can get a type of “memory”, and if it is left partly charged more often than it is full, it tends to drain to that point more quickly.
Charge it slowly
A constant and slow charge is better for your battery compared to a fast, heavy charge. Even better, this won’t overheat the plates in a typical battery as much, letting the battery last longer.
Stow Your Battery Properly
During the off-season, store it in a cool, dry place. And, if possible, keep a trickle charge on it.
Never Mix Types of Batteries
Avoid using an old and a new battery together.
Top It off with Distilled Water
If you’re using a wet-cell battery, check them from time to time and top them off with distilled water if necessary. However, never use tap water in batteries – only distilled water.
Check the Battery Terminals Regularly
Whenever you’re in the battery compartment connecting the charger, always check the battery terminals. Bond checking the terminals into another activity that you do: adding oil, gassing the boat, etc.
That way you won’t fail to check the terminals. If they are looking bad, disconnect the battery cables and clean the terminals up with water and baking soda. Then, dry them properly and reattach the cables. On the other hand, using a cell post spray on the terminals can help reduce the buildup that you might see on the terminals.
Frequently Asked Questions (FAQs)
Q: What Is an AGM Battery?
A: AGM stands for (absorbed glass mat) battery. Its main feature is a special glass mat separator. This glass mat wicks the electrolyte solution between the battery plates. As a result, it enables the battery to hold the charge exceptionally better than lead batteries.
Q: Can an AGM Battery Explode?
A: You risk exploding an AGM battery if you try using a conventional battery charger. While there’s more chance of the battery being severely damaged and risk making it ineffective, an explosion is surely possible. Therefore, you should always use a proper charger for an AGM battery.
Q: Can I Use a Car Battery/ Law and Garden Battery for Trolling Motor?
A: Unless you want to destroy your trolling motor, do not use car batteries. And while you can use a garden tractor battery for starting the trolling motor engine, you can’t actually keep the motor running longer than about 10 minutes. Therefore, just stick to using proper trolling motor batteries.
Q: What Kind of Battery Do I Need for My Trolling Motor?
A: There are two types of batteries: starter batteries and deep cycle batteries. Starter batteries are used to discharge a large amount of current over a short time. These are used in cars. On the other hand, deep cycle batteries discharge small amounts of current over more extended periods. For your trolling motor, you need to use deep cycle batteries.
Q: Are There Different Types of Deep Cycle Batteries?
A: Yes, there are two kinds of deep cycle batteries: lead-acid wet cell batteries and sealed absorbed glass mat (AGM) batteries. Lead-acid batteries are the most affordable option. They last for 2-3 years and require regular maintenance, including topping up the battery with distilled water from time to time. They may cost less but can be prone to leakage. These typically cost less than $100.
AGM batteries, on the other hand, are newer sealed batteries that don’t require much maintenance. They hold a charge for more extended periods but are more expensive. These batteries cost almost twice as much as lead-acid batteries but can last for about four years. If budget is an issue, go in for lead-acid batteries. However, for longer life and low maintenance, AGM batteries are the better choice.
Q: What Do You Mean by Amperage Hour Rating?
A: To put it simply, a battery rated for 115 amp hours will last longer than one with a 100 amp hour rating. Also, a 100 amp hour battery using four amps of current will last 25 hours. The same battery using ten amps of current will last for 10 hours.
Generally speaking, for a trolling motor, you would need to use a battery with at least a 100 amp hour rating. You should be able to get batteries with such ratings in lead-acid as well as AGM battery types.
Final Verdict
The hunt for the best battery does not have to be stressful. The above review is a suggestion of the best trolling motor battery. It only provides you with a long low maintenance life span, a fast charge time, high life span, and flexibility.
So, take a look at these batteries and ensure that you measure them up to get one that matches your needs. These batteries are available at various prices. Consequently, make sure that you don’t base your decision on cost alone but the features in them. By doing so, you can be certain to make the right investment and one that is worth your hard-earned money.
