Things To Consider While Buying a Good Trolling Motor Battery
There are several brands of trolling motor batteries out there with varying quality and dependability. To pick the best product for your boat, there are certain factors you should pay attention to.
Type of Battery
This is probably the most important consideration you need to make when choosing a battery for your trolling motor.
There are three main types of batteries for trolling motors - wet-cell, lithium-ion, and AGM batteries. Each of this type of battery has its own advantages and disadvantages.
The wet-cell batteries are usually the cheapest options, but they require a lot of maintenance and last for only one or two years.
When purchasing any product, it's always advisable to go for a brand that has a warranty. This gives you the chance to get back your money or at least a replacement in the event the product doesn't arrive whole or gets damaged after a few weeks of use.
Luckily, all the items on the list come with a decent warranty which guarantees their quality. But of course, you may still want to skim over reviews left by other people who have used the product.
Whatever you do, you must always remember that your batteries are only as good as the charger you use for charging them. A bad charger or one that is not compatible with your batteries will only make the battery look as bad. And you may have to replace the battery too soon due to frequent charging.
So while selecting a battery, also pay attention to the charger you are going to use for it. If you already have charger onboard, then you might want to select a battery that is compatible with it.
If not, then you should also consider investing in an excellent charger that will work well with your device.
Weight of the Battery
Another important consideration to make when choosing a trolling motor battery is weight.
Except you are approaching your boat's weight limit, it is generally recommended to go larger battery; usually, the bigger, the better. And the reason for this is quite simple - more weight directly translates to more lead in the battery core which means the battery is going to run for a longer time without charging.
While this sounds cool, it might not always be convenient to carry a big battery around. Most of the batteries in the market weigh between 20-50 pounds.
For many anglers and kayakers, anything below 30 pounds is the deal. But again it all depends on your purpose and weight capacity.
