Purpose
The Vmaxtanks MR137 is a deep cycle marine battery and it is designed to be used for deep cycle applications like powering up onboard appliances such as trolling motors and other accessories that require heavy power load. This marine battery is best for producing thrust on 55 lb to 110 lb Minn Kota, cobra, Newport vessels, sevylor and other trolling motors of that weight and for those marine enthusiasts who want a 12 volts group 31 deep cycle battery for their work or hobby. This battery is a very powerful unit and can be used even for off marine use.
Advantages and limitations
The Vmaxtanks MR137 is the most powerful deep cycle battery produced by the VMAXTANKS. With power voltage of 12 volts and 120 amp hour rating, it is able to provide massive deep cycle power than any other standard marine battery in its class. Due to the heavy duty lead-tin alloy grids, this battery is capable of high performance, very long float life and long duration even in cyclic operations. The AGM or absorbed glass mate technology ensures maintenance free operations such as no requirement of routine electrolyte gravity check and refilling of distilled water because of the recombinant technology within the battery. The battery can continuously run for 4 to 7 hours without being recharged for a long time.
The battery has been sealed in a way that the battery is not only resistant to vibrations and shocks but it is also spill proof, which makes the battery flexible to any mounting position without really causing damage to the battery or hampering the battery service life. This battery can withstand the harshest climatic conditions and it can bear extreme hot as well as cold temperature. The container of the battery is flame proof rugged and extremely strong; so one can care freely rely on this battery.
The Vmaxtanks MR137 deep cycle battery is specially designed for 55 lb to 110 lb trolling motors and in case it is used for thrusting lighter trolling motors then it might be too powerful. For the lighter ones you can go for Vmaxtanks MR107 or VMAX857, both of which are also deep cycle AGM marine batteries but designed for the trolling motors with lighter weight. As it is an AGM battery, there is a risk of overcharging, so extra care must be taken while charging it.
Conclusion
This deep cycle marine battery is a very strong, durable and reliable battery with so many tempting features. If you need a battery with the above parameters, then nothing can be as good as this battery and it is also available in a very affordable price.
