Key Specifications Of VMAX 6 Volt 225Ah AGM Battery

VMAXTANKS 6 Volt 225Ah AGM Battery: High Capacity & Maintenance Free Deep Cycle Battery for Golf Carts, Solar Energy, Wind Energy. The float service life span of VMAX AGM batteries range between eight to ten years. They are designed for long-running, heavy-duty applications.

The absorbed glass mat technology is designed with high porosity and fully absorbs and contains the battery electrolyte.

This not only provides it with its deep-cycle action, but it also extends the service life of the battery far beyond that of its closest competitors.

This design, which does not include the use of contaminants or silica gels, is also a greener and safer option.

Further enhancement of the battery is provided by the heavy-duty grids employed in the VMAX battery’s manufacturing.

The heavy-duty, lead-tin alloys used for the plates provide VMAX batteries with better performance and a much longer life span.

In either float or cyclic use, VMAX AGM batteries offer better performance and lifespan even after repetitive over-discharging.

This makes these batteries ideal for marine, industrial, and commercial applications.

Because of the free maintenance design, it will never require you to check the electrolyte’s gravity level or need to be filled up with water.

In fact, as you will notice with VMAX AGM batteries, no provisions are made to do such maintenance.

However, if these batteries are to be used on 12v circuitry, it may require the installation of two series-connected batteries to handle the required load.

With such a long lifespan and convenient performance, though, it would not be much of a bother to compensate for this problem.

How To Use The VMAX 6 Volt 225Ah AGM Battery

There isn’t much to do to get the most out of your VMAX 6 Volt AGM Battery.

Once unboxed, it may require charging before use simply to ensure that you get to enjoy the full use and life span of your battery.

During a float charge, it may take 48 to 96 hours to get a full charge.

Alternatively, you can fast-charge your battery for 12 to 24 hours. To fit the connectors to the battery terminals, unscrew the provided bolts, fit the connector, and re-install the terminal.

It is rather basic and straightforward. Of course, for further safety instructions and operation guides, visit the manufacturer’s website and go to the FAQ section.

Who Should Buy

Anyone needing to replace a deep cycle battery for RVs boats can feel free to invest in the VMAX 6 volt battery.

It is also great for commercial systems, home backup generators, golf carts, high powered automobile audio systems, or any other kind of use.

Even people looking to replace the battery on their electric wheelchairs or any similar apparatus would be welcome to try out this VMAX.

However, due to the lower voltage output, it is not meant for powering motor engines or the like that would require the installation of a 12-volt battery.

With deep cycle action, it is suitable for powering boat and RV appliances but may require a couple of batteries connected in series.

These batteries do allow applications in series, and buying multiple units is not a bad idea. These batteries are surely worth the investment.
