Find Your Trolling Motor Battery: The Ultimate Trolling Motor Battery Guide!

​Choosing a new 12-volt marine battery for your vessel can be an intimidating task for first-time buyers. Many kinds are accessible, each with a different reason, and each with diverse advantages and handicaps. With this handy buyer’s guide, although, you’ll have effortlessly understandable information at your fingertips so you can select an electric battery perfect for the tasks at hand.

Basic Battery Types

There are two rudimentary kinds of 12-volt electric batteries: 1) cranking, or starting, electric batteries, which are conceived to start your main motor, and 2) deep-cycle electric batteries, which are utilized to power electric accessories such as trolling motors, fish-finders and radios. Dual-purpose electric batteries that can present both these functions to some extent furthermore are accessible.

Cranking Electric Batteries

Engine cranking requires lots of power in a short burst. An electric battery with more exterior area on the lead plates inside it consigns more fast power than one with less plate surface. For this cause, cranking electric batteries are made with thinner, more many lead plates. When the motor is running, the electric battery is quickly replaced by the alternator.The marine cranking amp (MCA), or just cranking amp (CA), ranking found on a battery’s mark measures a battery’s beginning power. And if you’re utilizing a newer form outboard with sophisticated computers, pumps and sensors that don’t take kindly to being underpowered, you certainly don’t desire to scrimp on beginning power. Check your engine’s manual for its suggested MCA/CA ranking before buying for a battery, and always choose a battery with a rating equal to or greater than the suggested value.

Deep-Cycle Electric Batteries

Trolling engines and other accessories sip power at a slower rate for expanded time span. Electric batteries that power them usually aren’t recharged until the end of the day. These deep discharges are hard on electric battery plates, so deep-cycle electric batteries have less yet wider lead plates than cranking batteries and are constructed to withstand deep biking.A deep-cycle battery’s book capability (RC) ranking shows how long it can carry a exact burden before dropping into the dead zone. The higher the RC number, the longer the electric battery will power your accessories. Recall this when selecting a electric battery. Typically, a deep-cycle battery will have two or three times the RC of a cranking electric battery. A deep-cycle electric battery furthermore can withstand some century discharge/recharge circuits, while a cranking battery is not conceived to be completely discharged.

No Substitutions

The key thing to remember when purchasing cranking and deep-cycle battery kinds is not to alternate one for the other. If you use a cranking battery to power your trolling motor, for example, the battery will shortly overheat and go wrong, departing you without power and needing you to purchase a new electric battery. A deep-cycle battery exchanged for a cranking electric battery, on the other hand, may not supply the power required to start your outboard. You could get stuck with a motor that won’t run. The inherent conceive power of each battery type furthermore is their flaws in converse applications.

Dual-Purpose Electric Batteries

It’s generally best to establish separate cranking and deep-cycle batteries. If your vessel is small, however, and there’s only room for one battery due to space or heaviness restrictions, consider buying a dual-purpose marine battery specially that manages beginning and biking. Bear in mind, however, most dual-purpose batteries won’t start an engine rather as well as a factual cranking electric battery and won’t tolerate as many deep discharge/recharge circuits as a dedicated deep-cycle form.

Wet Cell, Gel or AGM?

Electric batteries can be farther categorized as damp cell, gel or AGM (absorbed glass mat), depending on the configuration of the electrolyte, or conducting medium, interior the electric battery. Each kind has pros and cons you should understand before making a purchase.

Wet-Cell Electric Batteries 

The customary lead-acid batteries we all are familiar with are wet-cell or “flooded-cell” batteries. Each wet-cell battery comprises a liquid blend of sulfuric unpleasant and distilled water (usually referred to as “electric battery acid”). This is the most well liked electric battery type, primarily because the cost is usually less than other types, but also because these electric batteries have a number of inherent advantages. For demonstration, a correctly ascribed and sustained, premium wet-cell electric battery is adept of as numerous as 1,000 discharge/recharge cycles. This can translate to many years of dependable service at an initial cost substantially less than comparable capability gel or AGM electric batteries. Wet-cell electric batteries furthermore are less expected to be damaged by overcharging and tend to weigh less than comparable gel or AGM electric batteries.
