This VMAX MR137-120 Deep Cycle 12V 120Ah Battery is better version of any of the batteries they have in the market. It belongs to group 31, which means, you can expect it to take load of high powered motors by minnkota. This battery can easily be connected into the minnkota motor.
This vmax battery has one of the solid bodies in the market. They have used better materials than traditional batteries. The body is made of industrial grade plastic, which is shock proof and acid proof. You can install the battery in MinniKota power kit to further protect it from jerks and rough use.
The battery is integrated with electrolyte suspension system. It contains AGM, which stands for absorbed glass matt, having very high porosity and absorbing factor. As a result, electrolyte is uniformly distributed and absorbed by it, making it to deliver constant power throughout the operation. No silica gels and other absorbers are used. Tin alloy is used for making the grids of the battery. This provide good conduction, and increase the life of the group 31 agm deep cycle marine battery. Grid prevents the hysteric effect caused by repeated discharging and charging of the battery.
It can repeatedly discharged and charged, without having an impact on the maximum power of the battery. This is due to the AGM technology used, it gives extremely good results on a deep cycle recharge. The battery when used for motor boats, it can deliver non-stop, constant power. Deep cycle capability of this battery is really commendable.
This group 31 deep cycle marine battery can get charged twice fast as much as traditional batteries. It depends upon the charger initially, but you will find that with same charger, this battery takes less time, around 40% less than any other battery on the board. The battery also charge well, giving constant power.
Due to the solid body, tin alloy plates, and materials, it offers better resistance against vibrations, this 12v 120ah deep cycle battery won’t go anywhere in 10 years of time. You may need to change the acid, but never the outer part. If it is installed in minnkota saltwater power unit, than you may expect it to run as much as you want.
Price of the battery is little more than traditional batteries, but that is obvious due to features, tin alloy plates, and AGM technology. The battery has very good performance, and deep cycle capabilities. Buying at the price won’t make your pocket burn, because the product you’re getting is worth it.
