Purpose
The VMAX857 AGM Battery is applicable for deep cycle purposes. It is a perfect choice for those who have small boats and less room for a battery to run some onboard accessories like trolling motors. It best suits for small boats and ideal for 18 to 35 lb Minn Kota, cobra, sevylor and other trolling motors that require a 12 volt battery with 35 AH capacity or less, belonging to group U1. It offers good thrust performance and it can be used in all weather situations, without any utility limit.
Advantages and limitations
VMAXTANKS batteries are best known for their long durability and the capability to recover from deep discharges. In the AGM design of this battery, no silica gel or other contaminants were used, due to which the battery is able to offer high performance as the mate is completely able to absorb the electrolyte. No excessive gases are able to accumulate inside the battery as this battery has been designed with safety release valves with automatic reseal feature. The self discharge rate of the VMAX857 AGM Battery is around 1% to 2% per month, which makes it superior as compared to 2% to 3% self discharge rate of other standard deep cycle batteries.
The rugged construction and unique sealing technology of this battery guarantee leak proof operation and mounting ability at any position without causing any effect to the function and durability of the battery. The ultra strong ABS container of the battery reduces issues of case bulging and plate warping, which ensures high performance and enhanced durability. The main heart of this battery lies in the plates of the battery, which has been designed and manufactured using special treatment and technology that gives them distinct physical and chemical structure than the other lead-calcium plates.
One important drawback of this battery is that it is applicable only for deep cycle purpose and strictly recommended not to be used for cranking purposes. Only an AGM smart charger must be used for charging this battery and in case a wet battery charger is used, it might cause permanent damage to this battery. It is only suitable for 18 to 35 lb trolling motors and might not be that powerful for running trolling motors with greater weight.
Conclusion
This battery is a very reliable deep cycle battery and nothing can replace it on its specialization and applications; it is affordable in quite a good deal.
