Rating : 4.8/5

Why is it Our Top Pick ?

This all-weather dual-purpose battery is guaranteed to be both durable and reliable, providing substantial vibration resistance while delivering serious power for such a lightweight battery, we think it’s more than worth the slightly higher price.

BlueTop offers great power for value

Powerful, but reliable. We prefer this battery for a few reasons, but mostly we like its sheer power coupled with its impressive endurance.

When investigating our options, we’re always drawn to the more powerful batteries because—let’s face it—they’re more fun.

However, this battery is also reliable.

As a result of the lower internal resistance, the power output is not muted but it still offers three times more recharges than the average battery.

Durable, but hands off

One of the most admirable features about this product is the fact that it is maintenance free.

Totally spill proof and mountable in any position means that you can stick to enjoying the water and leave the work to the battery.

Also, no need to worry about the weather, as this BlueTop starts in even the fiercest gales.

Long lasting, without being heavy

With the BlueTop, you can run it all day and still make it back home—and the best part—you don’t have to lug a gigantic piece of lead.

This BlueTop is light weight and more portable than competitors.

This battery doesn’t just last all day, some satisfied purchasers have claimed the battery lasted them up to eight years without compromising power.


● 12-Volt, 750 CCA

● Size: 10" x 6 7/8" x 7

● Dual SAE & 5/16" Stainless Steel Stud Posts

As mentioned, this 12 volt BlueTop is dual purpose.

It is a true deep-cycle battery, meaning that it offers, apart from firing up your engine, quick rechargeability without damage to the longevity or integrity of the battery.

So, for you, this means more time spent out on the water without having to head back online to look for a replacement.

Its lightweight body, at about 43 pounds and measuring 10 x 6.9 x 7.8 inches means that you don’t have to throw out your back hauling it around with you.

Compared with the competition, the BlueTop weighs in at “manageable” and so is easily portable.

Thanks to the Dual SAE & 5/16″ Stainless Steel Stud Posts and the unique, patented Sprialcell Technology® AGM, this battery is the king of durability, resisting the damaging vibrations of waves that might otherwise damage its integrity.

In addition to being tough, it’s a workhorse—the BlueTop prides itself on 120 hours reserve capacity even while running with the power at maximum

The Bottom Line

We can’t stress enough that if you’re looking for power, reliability, and durability—this is the battery for you.

Apart from being the all around best product, we think Bluetop takes the cake because BlueTop is a trusted brand. At a slightly higher cost than competitors, the bells and whistles on this one compensate for the price differential.​

- Exide XMC-31 MEGACYCLE AGM-200 Sealed Maintenance Free (AGM) Marine Battery -

Offering a maximum 1110 MCA starting power, for pep when you need it, this deep-cycle marine battery brings a lot to the table in standard features—but the Megacycle blows away the competition with 200 hours of reserve capacity!

Exide XMC-31 review

Rating : 4.5/5

Reserve capacity, means you can reserve your worries for the water.

For power and an assortment of impressive, standard features, look no further for a high quality marine battery for the right price.

The main selling point on this battery is its reserve capacity, but also its deep cycling capabilities which mean less worrying about the durability and longevity of your battery because you can always charge it up to full capacity again—and in flash!

Great reserve capacity, but that’s not all

The run time on this model is almost unmatched— at 200 hours reserve capacity, but this feature does not outshine the other benefits of the Megacycle.

A true deep cycle marine battery, the Megacycle can be almost completely discharged and be quickly returned to its full charge.

The only caveat—it requires a serious charger.

Charges fast—with a monster charger

You will need a serious charger to get this battery to full capacity, but if you have the tools, you won’t be disappointed.

This can be a drawback when comparing prices because buyers don’t always factor in the additional cost of a heavy-duty charger.

Not as vibration resistant as some

While it offers some vibration resistance, it lacks this as a defining feature and has been known to cause an annoying level of vibration… only annoying, not harmful.


● 12-volt

● 925 CCA

● 74.6 pounds

● 15.7 x 13.9 x 9.8 inches

The Exide Megacycle rings in at 74.6 pounds, which is heavier than some competitor models. This might mean a little back pain if you’re planning on hauling it. Close to a standard size, 15.7 x 13.9 x 9.8 inches, it’s mountable in any position, although the manufacturer does not recommend an inverted orientation.

The Bottom Line​

The Exide Megacycle AGM-200 battery is an excellent product. The Megacycle will not leave you wishing for more power and you’d be hard-pressed to find a battery on the market that provides the kind of reserve capacity that the Megacycle offers.​

With the reliable Optima name, this BlueTop delivers power and reliability at a reasonable cost—without sacrificing performance

Optima Batteries 8052-161 D31M BlueTop Starting and Deep Cycle Battery REVIEW

Rating : 4.5/5

Best in class power and dual purpose, but affordable too.

This BlueTop D31M is not just good value, it’s downright affordable for being a best in class choice. With deep-cycle capabilities and greater than average power, this battery has triple the capacity of its competitor class batteries. Like other Optima batteries, you can expect a premium product for the price. This means you can expect power and reliability with this BlueTop, as well as a long-lasting product that will continually deliver.

No maintenance, so zero trouble for you

Like other Optima batteries, this BlueTop is hands-off. Thanks to the fact that it is totally spillproof and vibration resistant. This means there is no need to replace water in the battery and because it’s mountable in any position, it’s basically good to go.

Dual-Purpose is doubly easy

The dual purpose capability of this battery means that you can start up and continually keep going without fear running out of reserve power capacity.

Recharging can be tricky

This battery can recharge very quickly, but you must be careful to ensure that you use the correct voltage when recharging. Otherwise, the battery can be ruined since it’s sealed and can’t be repaired, but instead must be completely replaced. Just follow the instructions and everything should go alright.


● 12-volt, 900 CCA

● 59.8 lb

● 12.81 x 6.56 x 9.38

This BlueTop is a dual-purpose AGM battery with a standard 12 Volts. A deep-cycle top quality marine battery, it has a CCA rating of more than 1000 with a capacity of 75A. It is compatible for variety of uses: commercial watercraft and off-road vehicles, among other uses.

The Bottom Line

Without hesitation we can recommend using this battery because it offers good value for a best in class product, without leaving you to desire more power or surprising you by leaving you stranded somewhere. Optima’s BlueTops offer consistent quality and value for a fair price.

This Optima battery the necessary power for a variety of uses without breaking the bank

Optima Batteries 8027-127-FFP D27M BlueTop Starting and Deep Cycle Marine Battery review

Rating : 4.4/5

This BlueTop is an affordable option for those that don’t need quite the power or reserve capacity of some higher priced models. While offering the same deep-cycle capabilities, you’ll end up spending less for this model while not compromising the quality or integrity of its performance.

You can still expect a premium product for the price that delivers power and reliability, as well as continual function for extended use.

An Optima battery through and through

Optima batteries offer an array of attractive features. They’re maintenance-free, spill proof, all-weather, shock resistant and vibration proof. This means, you get a quality product and a guarantee of top-notch manufacturing.

Dual-Purpose for starting and deep cycle

This BlueTop is still dual purpose so you can start it up and while being certain you will still be able to tap into that reserve power, should you need it.

Less power, means dual purpose might not suffice

Depending on your intended use for this battery, you may find that the dual function does not pack enough punch to crank up the amps and continually run deep cycle for as long as some competitors. However, for most purposes, this battery packs the necessary power and reserve capacity.


● 12-volt, 800 CCA

● 12.2 x 6.8 x 8.7

● 57 lbs​

The Bottom Line

This BlueTop guarantees superior value by offering the power and reserve capacity matched in similar models, but at a lower price when taking quality and longevity into consideration.

Including all of the starting and deep-cycle capabilities you require, you’ll end up spending less for this model without failing to benefit from its performance.
