Mighty Max Battery Charging Instructions

The Mighty Max batteries are deep-cycle batteries. That’s why you better know how to charge a deep-cycle battery. Obviously, these are not car batteries or marine batteries, or any other standard batteries. So, you must know some vital points about charging the Mighty Max battery.

You can charge these batteries using either a portable charger or a fixed charging source. Nonetheless, I prefer using a portable charger to a fixed charging source.

First and foremost, you have to use the correct charger, which is fast. Unfortunately, the Mighty Max batteries don’t come with a charger in the package, though. You have to buy a charger separately.

Not charging in a sealed container is vital as the company instructs this for each of its batteries.

Although the batteries come fully charged, and you can use them right off the bat, equalization charging is necessary at least once a month or for every 10 discharge cycles.

If you don’t know what equalization charging is, it’s the process of charging a 12V battery with at least 14.4 volts for at least one hour.
