One of the best features of the DieHard AGM Marine Battery is its long-lasting performance. This one, believe it or not, features vibration resistance that is 20 times better than most of its competitors. This capability alone secures its ability in extended periods of use.
Furthermore, it doubles the cycle life of the battery, which you can never experience when you are using conventional lead-acid batteries. For motorboats out there, considering this marine battery in your rig should never be a regrettable choice.
The battery also offers a spill-proof design so that you don't have to deal with harmful residues anymore. Moreover, gas and toxic emissions are not part of the trade-offs when using this battery. You can say that it is a sophisticated boating accessory that guarantees an uninhibited power generation.
You can also enjoy the fact that the positive and negative plates of this battery has been optimized so that it won't experience electrical shortages, which can harm its overall lifespan.
You don't need to spend big before you can get a high-quality and perfectly robust marine battery. One suitable proof of that is the Mighty Max Battery ML35-12. This one is a 12-volt 35AH Sealed Lead Acid (SLA) battery that offers a maintenance-free performance. It still provides a spill-proof quality to prevent the creation of harmful residues over time.
The discharge rate is pretty impressive, as well. Meanwhile, its ideal operational temperature is quite extensive. Whether it is hot or cold, this battery can crank power to your boat's engine.
The high-quality engineering that has been employed on this battery maximized its service life and deep discharge recovery. In boating applications, such a performance is worth taking in. You will really need a battery that can crank continuous power without losing its stability.
When it comes to ergonomics, the Might Max Marine Battery proves to be a satisfying choice. It is not as heavy as its counterparts. Moreover, you can mount it in various positions. It provides shock-resistance, too.
As a dual-purpose battery, I cannot help but be amazed by the quality of the Odyssey Marine Battery. It can work for cranking and deep cycle applications without losing an iota of efficiency. It is extremely powerful and stable at the same time! You can rely on it in different conditions without having to worry that it will give up on you.
This battery features 1150 cold crank amps, which enables it to generate huge cranking power. It is capable of powering various outboard and inboard motors without breaking any sweat.
The deep cycling of this battery is almost unreal. Based on some tests, the battery can last up to 400 cycles, even if the depth of discharge is at 80% already. Almost no marine battery can offer such performance. Since the Odyssey is rated 100Ah, it is already a given that it can produce up to 5 amps of current every hour for at least 20 hours. Therefore, even if you do some overnight boating excursions and trolling, this battery won't leave you hanging.
Another marine battery that is worth considering is the VMAX XTR31-135. This one also provides a powerful performance without compromising its service life on the process. Just like all of the batteries here, the VMAX XTR31-135 doesn't require maintenance. Once it is installed in your boat, it will operate on its own.
It has a rugged construction so that it can withstand the test of the elements. Furthermore, it has a great defense against vibration and impact--ensuring that all of its internal parts are secured.
Keep in mind that this one is an AGM battery. Therefore, aside from being a reliable power source, it also allows multiple mounting positions. You can install it on any angle without any problems. Moreover, the VMAX XTR31-135 can be submerged in the water temporarily. After all, it has a seamless shell that prevents the entry of water and other damaging elements. All of the plates used on this battery are downright superior and offers a service lifespan of up to 12 years.
Choosing The Best Marine Battery For Your Boat: Guidelines
The battery of a boat is indeed essential. There's no denying about that. The vessel won't run anyway if it is not equipped with the right kind of battery. Unless you are using a pedal or paddle-operated watercraft such as kayaks and stand-up paddleboards, you will really need to invest in these batteries.
However, the process of selecting a battery for your boat is not that simple. You don't pick a battery without thinking first if it can work for your rig or not. Being smart about this can really affect the performance of your boat for the better. And for me, that's something worth looking forward to.
Here are some of the things that you need to know whenever you are choosing a marine battery for your watercraft.
You can choose a battery based on its intended application.
These starting batteries are capable of cranking the starter of your vessel engine. You can consider them as the sprinter of the entire electrical body of your boat. A starting battery can provide 75 to 400 amperes of power for around 5 to 15 seconds. After that, the alternator of the boat's engine will recharge it for a short order.
Similar to the standard lead-acid batteries, starting batteries features a design where the layers of positive and negative plates alternate with one another. You can see insulation layers in between the plates.
Noticeably, starting batteries are thin, but they contain a lot of plates. Such a construction enables them to provide a larger surface area so that the battery can create currents with high amperage.
However, there are drawbacks for this design. First, the plates are not durable. They are fragile and susceptible to breaking, especially if you put them in harsh environments. Second, this design is not compatible with deep discharges. As a result, their lifespan is not that great.
Deep Cycle Batteries
Most of the boats these days are using deep cycle batteries. You can consider them as the ultimate workhorse or the ultra-durable runners when it comes to powering your engine. They are the ones that operate the electrical loads on your watercraft whenever there is no charge source (i.e. engine alternator, solar panel, or shore power charger). You can see the as efficient piggy banks in where your energy is being saved and withdrawn.
If you place deep cycle batteries side by side with starting batteries, you can easily see that the former is not designed to generate bursts of power in short durations. Instead, deep cycle batteries will only recover when it has been discharged slowly on extended periods. This mechanism is where the battery got its name.
Specifically, deep cycle batteries have thick plates. It is also noticeable that they have high antimony content. In a single night, these deep cycle batteries can deplete up to 70% of its overall capacity. This depends on the loads of being consumed by the boat. When recharging the battery, the power is being deposited again on its bank. The cycling process starts again.
Here is a brief explanation on how deep cycle batteries works:
Dual Purpose Batteries
A dual-purpose battery is somehow designed to get the best features of starting batteries and deep cycle batteries. It has large and thick plates that contain high levels of antimony than starting batteries. It also features unique chemistry that includes an active lead paste composition.
Because of its unique construction, dual-purpose batteries can accommodate deep discharges that are potentially dangerous when it comes to starting batteries. Furthermore, the lower storage capacity of these dual-purpose batteries allows them to generate bursts of energy.
However, the applications where you can use these dual-purpose batteries may be limited. You can use them on small power boats that are utilizing a single battery for both of its running and starting loads. Alternatively, you can have this battery on sailboats that are using similar batteries for its house and starting electrical loads.
Chemistry Of The Battery
Most of the marine batteries are using either of the following chemical compositions: gel, absorbed glass mat (AGM), lithium, and gel. Each of them has been made to accommodate specific marine applications.
Your boat requires the best marine battery. There's no arguing about that. Your vessel wouldn't function the way you expect it if you outfitted it with poorly made and highly volatile batteries.
The ones that I featured here will certainly provide your boat with relentless performance without experiencing hassle in maintenance. They work well as long-term investments because they are built to last long!
