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.

Please read my review completely to the end. Open your old jump box and see the battery connection before ordering. Make sure you order the AGM battery and 22AH the same as original JNC660 battery. this battery was EXACT FIT, and it was 100% charged out of the box, but still placed it on the NOCO GENIUS 10 battery charger, before installation. Keep the JNC660 plugged after installation. Installation is easy, just make sure to have double sided tape. the price is almost a third of the new jnc660 and worth every penny. Remember to disulfate the battery every year, by connecting the desulfating charger to the positive and negative clamp of the JNC660, and add many years to its life.

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

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!

great price, and the convenience of getting exactly what you need at your door, but the battery only lasted 7 months with no use.

I use these batteries to refurbish cat jump boxes they work very very well the cat jump box at half mast will still jump a car an amazing

ABSOLUTELY Not equivalent to the original JNC-660 jump box. This battery is very weak and mounts differently than the original JNC-660. This output on this "Mightmax" battery is less than 50% compared to a 2 year old genuine JNC battery in my other jump box measures. This jump battery will not start any 4 cylinder I have tried it on unless the battery is already partially charged. Customer service is HORRIBLE - I think it is either Ai, or some very ignorant person working for them. And this battery is self-discharging so it's dead every time I go to get the jump box.

wonderful

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

This Battery is the Best for long time. Strong Power and Lasting Drive with 48 Volt 20Ah. I recomend for You!

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.

My motomaster eliminator 400w power box/jump starter Battery would not hold any charge after 10 years, so I simply directed it and replaced the old battery with this new one. This new battery even has 2 more amp hours (22) than old one (20) works like new now! At a fraction of the cost.
