Advantages and limitations

The best thing in this battery is its powerful deep cycling ability and true deep cycle feature which is available in an easily affordable price. With the high porosity absorbed glass mate electrolyte suspension system, the mate is able to completely absorb the pure electrolyte that is not contaminated with silicates or other unnecessary elements, which provides the battery with enhanced performance capability.

The sealing is done so smoothly that there is no risk of spill or leak and this battery can be mounted at any position without any functional or physical damage. The lead-tin alloy grids improve the service life of this battery, giving it the same functioning capacity even after several discharges and recharges. The low internal resistance of the Vmaxtanks MR107 marine battery makes it 99% efficient and superior to other standard batteries of its class that are only 85% to 95% efficient. With this battery there is no risk of excessive gas accumulation within the battery as it has a special automatic resealing self releasing valve. A lot of time and also a lifetime expense can be saves as this battery requires least maintenance and needs no distilled water refilling.

A very important drawback of this battery is that is only applicable for deep cycle purpose and in case it is used for cranking the functionality of the battery might be damaged reducing its service life. It is good only for trolling motors with 30 lb to 55 lb weight and might not be powerful enough for heavier ones and it may also be too much powerful for that with lighter weights.
