Mighty Max Battery Mighty Max Battery ML22-12 - 12 Volt 22 AH, Nut and Bolt (NB) Terminal, Rechargeable SLA AGM Battery

I am a HAM Radio operator and this is my favorite choice for operating in the field. I go with two of them. The second is a backup.

wonderful

I replaced my original battery in my Jump-N-Carry JNC660 from 2016 with the MightyMax, it was 100% charged out of the box. Can't wait to get the opportunity to jump start someone's car to test!

Used in a battery jump pack that somebody had thrown away when the original battery had failed. I bought a similar Mighty Max battery back in 2017 which fixed it. That battery was now not holding its charge so well and this one replaced it. Eight years for a battery I think is great "mileage". It is used quite frequently and also used with a 12v winch on a utility trailer to unload leaves etc.

These batteries are awesome Will last two days at theme park per charge.

I waited 3 days longer then what I paid for it to get here then I open it up to see the whole back is busted out

Shipping was fast, however I'm disappointed with this battery. It doesn't hold proper charge as per the stats. With nothing but a multi-meter connected to it, you can watch as the voltage plummets. I'm not taking about dropping to storage voltage, I mean falling off a cliff. The next thing is the battery terminals. You have to have fingers like match sticks to connect anything to them. They are so small, and the space is so limited. You can't properly tighten the terminals properly either. Why? Because you risk stripping the screw head because you can't use bigger screws - the terminal holes are too small. I'm tired of returning products, tired of dealing with customer service that takes days to respond.... Edit- 10/12/23 (increased ⭐ rating) I reached out to their service dept, and I couldn't believe how quickly I was helped. I bought 3 other batteries from them, before this review, and they're working great, so it was really nice to get the issue sorted. I still don't like the terminals, however the battery service is excellent.

I replaced the battery in my old jump box with this and it works fine, it starts cars and trucks, my mower and golf cart. I have used it with an inverter plugged in to the jump box during power outages to power and charge phones , laptop, lights, etc.

super bien ,, test ok ,bon remplacement, ; je suis satisfait,, André.

Livraison plus longue que abitude Batterie 1iere cavité

Came quickly and arrived as described it would recommend

I purchased this battery in oct 2024, it is not good as it no longer holds or take a charge. However after contacting the sellers support they were able to help and sent a replacement battery. They acted swiftly and where very understanding. Great support, I will update once the replacement battery arrives and see how it holds up.

Works great, used it for my UPS.
