  • Boasting 100Ah, this battery offers great performance and can supply plenty of power to your trolling motor, or as an uninterrupted power supply for electrical equipment.

  • VMAX Marine have designed and built this battery using AGM (absorbent glass matt) technology, meaning it charges extremely quickly and doesn’t require the maintenance of a traditional lead acid battery.

  • Because this is a deep cycle battery, it can be discharged and charged many times with no negative effects on the battery’s capacity and performance.

  • Thanks to its thick plastic housing and effective design, this battery is extremely resistant to vibration and doesn’t damage easily.


  • Since this is a deep cycle battery, it can’t deliver the cranking power necessary to start an engine. This means you’ll need to use it alongside a starting battery to power your boat’s main engine.  

  • Weighing in at almost 70 pounds, this is a very large and heavy battery, largely due to its very thick plastic casing.

Thanks to its use of AGM technology, this is a 100% maintenance free battery that doesn’t need water refilling or other care. It charges extremely quickly, making it a convenient option if you’re looking for a battery that will often be used on your boat.

Add its durable, vibration resistant exterior housing into the equation, and the VMAX MR127 is a great deep cycle battery that’s available at a slight premium compared to competing batteries.


  • This is a large Group 27 battery, weighing in at 67 pounds. It’s designed to mount inside any compatible Group 27 battery box, making it relatively simple to mount in your boat or recreational vehicle.
  • Designed and manufactured using an AGM (absorbent glass mat) electrolyte suspension system, which removes the need to maintain the battery.
  • Extremely vibration resistant, with a thick external plastic case that protects the battery from knocks, scratches and vibration damage.

Thanks to its electrolyte suspension system, the VMAX MR127 delivers exceptional deep cycle performance. This battery is reliable and long lasting, making it a great choice for powering an outboard trolling motor or as an uninterrupted power source for 12v electrical devices.

One of the biggest advantages of this battery is its use of AGM technology. This means it needs no regular maintenance. It also improves the battery’s performance, letting it discharge its total capacity and recharge without damaging its ability to recharge or maintain its capacity.

A second advantage of the VMAX MR127 is its charging speed. This battery charges about two times as fast as similar batteries from other manufacturers, putting it near the top of its class regarding charging speed. This is very convenient if you need to use the battery regularly.

Finally, this is an extremely strong and rugged battery. It has one of the sturdiest plastic bodies we’ve ever seen on a commercial battery, giving it excellent durability and protecting the battery from damage caused by vibration.


Although this is a high-quality battery, it does have several weak points. The first is its weight. At almost 70 pounds, this is one of the heaviest deep cycle batteries we’ve tested, making it tough to move within your boat.

Once it’s mounted, this isn’t a particularly major issue — however, it’s important to be aware of the weight of this battery before you order. The battery is fitted with two folding carry handles to make it easier to carry, which come in very handy when moving it from your vehicle.
This is also a fairly expensive battery, with a retail price of almost $250. The price is justified in its performance and durability, but it’s certainly not a cheap product.


The VMAX MR127 is an excellent deep cycle battery. It performs well, charges quickly and has an extremely durable exterior. If you’re looking for a great deep cycle battery and don’t mind the slightly high price, the VMAX MR127 12 Volt 100Ah AGM is worth a serious look.
