On the negative side, there is not too much to say. The labelling on this battery is a little sparse and if you have a few different batteries in one place you might have trouble remembering exactly what the voltage and amperage on this one is.

If you use it heavily for around 6 months, it can start to lose the charge very quickly. The terminals are also quite thin, so if you want to connect it for testing reports you can have difficulty.

Verdict

This mighty max battery has a set of pros in its favor that really outweighs its negative side. It is priced well for what it can do, it does not need any maintenance and is nice and compact. It is powerful for its size and can be recharged with alternative methods, like solar panels.

It is suitable to marine applications, but can also keep your ham radio happy for hours. The terminals are thin, but should not be a problem unless you plan to test this battery often. Mighty Max has made a versatile and robust battery that you can easily use in a variety of settings.
