Where are Mighty Max Batteries Made\Manufactured?
Answer: Mighty Max is a U.S. brand based in Brooklyn, New York.
Mighty Max batteries any good?
Answer: Yes, of course. Yes, the batteries that I am mentioning here are AGM deep-cycle batteries used for your portable devices and tools.
They all share the general traits of any AGM battery such as they are maintenance-free, spilled proof and resistance to shocks and vibrations, valved-regulated, corrosion-free, long-lasting charge holding ability, slightly shorter charging time when compared to traditional batteries and of course safe & reliable fully.
Of course, all these deep-cycle batteries are good for the price and also inexpensive.
Mighty Max Battery Charging Instructions
They’re deep-cycle batteries. And that’s why you’d better know how to charge a deep-cycle battery. These aren’t car batteries, marine batteries, or made-up name-brand batteries. Now, you should have some critical knowledge about the battery charging.
These batteries can be charged with a portable charger or a fixed charging source. That said, I would sooner use a portable charger than a stationary charging outlet.
To begin with, you must use the right charger — a fast one. Sadly, batteries don’t include a charger in the package. The charger must be purchased separately.
Failing to charge in an enclosed container is critical, with the company giving this instruction for each battery.
The batteries are delivered and charged, so you can start using them right away, but equalization charging is done at least once per month or every ten discharge cycles.
In case you are not familiar with what equalization charging is, equalization charging means charging a 12V battery at or above 14.4 volts for a duration of at least one hour.
Final Words
In this Mighty Max battery reviews article, I’ve reviewed the eight numbers elaborating on their highs and lows.
I have also been writing about some of the major applications of each of them.
I hope you didn’t skip over the FAQ section and battery charging directions.
The best aspect of these batteries is that they provide performance and reliability without hurting the pocket.
They are low–weight and portable with good mounting and transportation facilities.
The small hiccups aside, I can bet you will not regret buying from this brand.
