Information technology'due south important to know the purpose the marine battery will serve on your gunkhole. Starter batteries are used to start a motor, and therefore deliver a large amount of cold cranking amps (CCA) or marine crank amps (MCA) to go the engine running. Deep cycle batteries are your onboard 12V power source for electric appliances or an electric motor. Dual purpose models combine both modes and offer the best of both worlds, effectively assuasive you to employ only one type of marine battery.
Usage
What's the purpose of your marine battery? If you but need a power source to turn on the engine, then you're looking for a starting battery. If you lot want to power onboard electronics and device, you'll need a deep wheel battery. If you require both of these and don't want to compromise on infinite and weight, consider a dual-purpose model that tin can serve both applications.
You also need to be aware of voltage requirements for your boat. A simple boat can have a bombardment for starting the motor, and running a fish finder, but if you add an electric trolling motor to the mix, you volition likely need a second battery.
Some boats, specially bigger ones, or specific employ type boats, like a bass boat, run the batteries in a series, take the 12-volt battery and adding another, or even a third to brand the gunkhole operate on a 24-volt, or 36-volt system. Know what you need and make certain the battery can handle being run in series if that is what your gunkhole requires.
Cranking or Starting Marine Battery
Starting an engine requires a sudden flare-up of ability, specially when cold. To reach this, cranking batteries characteristic a singled-out construction with more than and thinner atomic number 82 plates. Deeply discharging these could damage the plates.
Deep Cycle Marine Batteries
The main purpose of deep bicycle batteries is a slower simply steady belch to supply power to electronics. They allow for corking depth of discharge without damage, maintaining their chapters to exist recharged fully. They tin can be used for starting an engine, but but might not deliver plenty cold cranking amps.
Dual Purpose
These hybrid models serve as both starters and steady power sources. Their primary application is in situations where infinite is limited, or weight of batteries is an issue. Go on in mind that these take to compromise and can't outperform a dedicated starter or deep cycle bombardment in their respective applications.
Types of Marine Batteries
All of the batteries on our listing are Sealed Lead Acid (SLA) batteries. They're valve-regulated and are also called dry out, considering they can't spill and don't leak. This is accomplished using an Absorbent Glass Mat (AGM) to incorporate the bombardment acid, the electrolyte fluid. The released gases (hydrogen and oxygen) are nearly completely recombined within the battery, so in that location'due south no venting. This type of bombardment has the advantage that information technology's maintenance-gratuitous, and can be operated in nearly any mount position (except upside down). With the right charger, they're also quick to recharge.
Flooded or moisture batteries are not well suited for marine use, since they can spill or vent and pose a greater environmental chance, which is all-time avoided in marine utilise. They're too much more than susceptible to vibration and shock than AGM batteries, which is another disadvantage on the water.
Cold Cranking Amps
The starting power of a battery is rated in CCA, common cold cranking amps. Equally we've mentioned, information technology'south the amount of amperage the battery can provide for 30 2nd maintaining at to the lowest degree 7.2V at a temperature of 0°F. With a rating of around 500 CCA, the battery tin maintain up to 10V, whereas a value from 300 CCA on is the bare minimum needed to start an engine. Looking at the specifications of our selection above, you lot'll see that the deep wheel simply models merely nigh service this minimum, whereas the starter batteries characteristic a much righter rating.
Yous volition often encounter a value for MCA, also called Marine Cranking Amps. This takes into business relationship that for a boat or watercraft, the temperature of 0°F hardly applies. MCA therefore specifies the amperage produced by the battery at 32°F, which will exist higher than the CCA value. Look at what your engine requires for starting, then select a battery with a value that's at least equal or greater.
Chapters
Battery capacity is measured in Ampere hours, or Ah. A capacity of 100Ah means your battery tin can deliver that value for one hour, or 5A for 20 hours – or 20A for 5 hours. A college chapters ways you can run your appliances longer, which is important for deep bike batteries. Keep in mind that typically yous don't fully discharge the battery to preserve its lifespan and just become to a value referred to as the depth of discharge. A typical DOD is around 60%. In regular utilize, you will simply spend forty-50% of your deep wheel battery capacity, and then plan accordingly and construct a ability depository financial institution of several batteries if you have high power needs.
Reserve Capacity
The reserve chapters specifies the amount of minutes a battery can be discharged at a fixed charge per unit of 10.5V by 25A at 80°F. A higher rating means your battery will last longer under load, of course. Keep in mind that this is a theoretical value and in existent-life situations, you will probably draw less Amperage at a different temperature, resulting in longer bombardment life.
Dimensions & Weight
Size and weight can be an issue on a boat, and yous surely won't accept unlimited space bachelor for installing batteries. Bigger batteries come with higher capacities, but keep in heed you lot tin can wire several batteries together for more power. Portability is great if you need to motility the battery, so keep that in listen for the off-flavour time as you might move the bombardment into storage.
Battery Boxes
Marine batteries are, by necessity, exposed to some nasty conditions. Unfortunately, batteries don't do well with temperature fluctuations, salt water or rain. Since most marine batteries are exposed to exactly these things, at that place must be a expert way to protect them, right? If your boat doesn't already have a protected battery compartment, yous may need to buy a battery box. There are lots of them on the market but, before y'all get with the cheapest one, consider these ideas:
- Some battery boxes accept USB charging ports
- Some battery boxes are more water resistant than others
- Some battery boxes display info like battery health
A basic battery box should continue out pelting and splashing water. At the very to the lowest degree the box needs pass-through or external battery leads. On peak of that, your battery box should be strapped or fastened down. If y'all regularly have your bombardment out consider a quick strap and external thumb-screw bombardment leads. This will minimize the number of steps it takes to remove the battery.
Care and Charging
Taking intendance of your battery is ninety% of the boxing to keeping information technology in service as long equally possible. Batteries tin be fickle, and if you don't care for them properly, you'll be certain to shorten their lifespan.
Here are a few things yous tin do to extend the life of your battery:
- Keep your bombardment on a trickle charger as ofttimes as possible
- Install a quick-charging port for a trickle charger for hard-to-reach batteries
- Consult the user's manual that came with your bombardment and do everything it says to exercise
- Use dielectric grease to coat the terminals of your battery to prevent corrosion
- Avoid excessively cold or hot temperatures with your battery
One of the best things yous can exercise for your battery is to keep it topped off. Use a trickle charger mean solar day-to-day to help with this. Some other major threat to your bombardment life is extreme cold or oestrus. During the colder months of the year, store your battery attached to a trickle charger. When it starts to get hot out, keep your battery out of directly sunlight (battery boxes tin assistance with this).
Conclusion
We promise that our review and guide will be helpful in selecting the right kind of marine battery for your boat or vessel. Examine your power needs on board, and how much space yous accept bachelor for building a power bank to deliver current to your devices and appliances. Keeping things split with a starter and deep cycle battery is a common installation, only if you have little room or lower power needs and desire to salvage weight, a dual-purpose model could be your preferred pick.

FAQs
What type of battery do I need for my boat or vessel?
Marine batteries accept two major applications: starting batteries which deliver power for starting the engine, and deep cycle batteries which ability up devices and appliances onboard. These ii uses have different needs, which is why there are distinct bombardment designs. Starter batteries serve the purpose of cracking and getting the engine running with a burst of Cold Cranking Amps (CCA). On the other hand, deep cycle batteries deliver power over a longer menstruum of time and tin can be discharged far more than.
What is the best marine battery to buy?
Our selection for the best marine bombardment is the VMAXTANKS AGM Marine Deep Cycle Battery. It boasts a loftier chapters, loftier-quality structure and can evangelize a reliable functioning.
How long do marine batteries last?
On average, marine batteries tin last anywhere between 6 and 12 years. Information technology's important to keep yours fully charged every bit much as possible to prolong its lifespan.
Can a deep cycle battery start an engine?
In theory, yep, depending on the engine and the bombardment. Typically, deep cycle batteries evangelize less cold cranking amps, but might still exist sufficient to start an engine with their current. However, deep bike marine batteries aren't designed for this chore, and then you wouldn't want to waste matter a good battery. If y'all take room for simply ane battery on your boat, you lot should get a hybrid or dual purpose model.
Do I demand more than than one bombardment?
If you want to ability upward appliances onboard, you require at to the lowest degree a starter battery and 1 deep bicycle battery. According to your power needs, y'all can add more deep cycle batteries. Should you have express room available on your boat, a dual purpose marine battery tin can serve y'all for both starting the engine and powering up devices.
How do I store marine batteries?
Unlike types of batteries require specific treatment and storage, so brand certain to ever follow the manufacturer's instructions. Batteries should more often than not not be exposed to h2o. Ideally, flooded batteries should be stored and operated upright. AGM and lithium batteries tin also exist installed at an angle or vertically (only non upside down). Vibration is an issue for all battery types, and so try to minimize exposure to it for your marine batteries every bit it will shorten the lifespan. Never store the battery on bare footing, or on concrete, as this can damage the lifespan of the battery. And I strongly propose a trickle charger to go on the battery at optimal levels.
Is there whatsoever battery maintenance required?
Flooded batteries crave more than maintenance and need to be properly ventilated. Regularly check all batteries for corrosion, and brand certain they're not exposed to or submerged in water. A trickle charger, like a bombardment tender, is the all-time matter you can buy for your bombardment.
