the battery works and fits well in my old Canadian Tire Motomaster jumper and power supply pack.
Dan Johnson –
Good battery. Terminals point up. Make sure it is what you need.

This battery was a direct replacement for the original battery and has more power

Replaced the original battery in a jump start, light, air compressor, and other various functions pack. Now it works just like new, way better than yet another thing ending up in a landfill.
Charlie M. –
This battery fit just like the original even though it was a different brand and was easy to install and fix my jumping for less than the cost of a new one.

This is a great product. I recommend it to anyone looking for a battery.

It arrived fully charged: 12volts 9AH as advertised. This replaces a Generac OEM 12 volt battery rated at 10AH but it works perfectly. I can’t comment on longevity yet but it’s less than half the price of the Generac original replacement battery and it starts my generator without the slightest bit of strain, even during cranking. I added in a battery tender (trickle charger) with a 7 day timer to keep it topped off. I’ll update the review in a year to see how it holds up over time.

Fit perfect

No stars for longevity, as I haven’t had it that long. Seems strong on the start, holds charge well and got me back in business. Shipped quickly, so my down time wasn’t significant.

Great fit. Can’t speak of longevity, because we didn’t have it that long. Working great so far.

As the title says, I replaced an aging 7Ah battery in my portable jump starter (Cobra CJIC 250) with this and didn’t have to modify a thing. A number of screws, the two terminal bolts, some adhesive foam sheet to give it the same protection that the original had, and it worked right away.

The item was received quickly and as described. Battery took the initial charge and was installed in my portable jump pack. We will have to see how it holds up over time, and whether it has the amperage necessary? So far so good…

Cheaper than buying new emergency charger.

Has plenty of power to crank the 8000 wt . perfect fit in the box. Like the new screw and nuts provided

Used this for a jump starter.
Michael Edwards –
This battery was a perfect fit for my rally 7471 jump starter. I’ve only used it a couple times since installing the battery but it seems to work good.
Web Customer –
The battery that I ordered arrived dead. Tried to charge it but the charger would not accept it. When contacting customer service about the problem they acted fast and sent out a replacement. I needed another battery of the same type and ordered from them again mainly because I found the customer service they offered was great. Not sure how well the batteries will perform, but so far so good.

I’ve never heard of Mighty Max batteries before, but this battery has been doing a good job for a couple of months now.
Web Customer –
Perfect fit replacement on my Generac generator.

Replaced defective jump starter battery. Mighty Max 12v 9 ah battery post slightly shorter in height. Had to drill larger hole on jump starter terminal connector to accommodate screw and bolt. Batteries arrived full charged.

The post are to short. Took longer to install the battery than it did to replace the carburetor on my generator. Had to use smaller nut and bolt to hold the cables on.

Bought this for a 8500w generator that’s only used once or twice a year. It has more than enough power to handle starting it. Decent price, right fit, quick shipping. Do to the infrequent use I will probably have to recharge it periodically but I knew that going in, or maybe not it might surprise me. Happy so far. Aloha

After a few power outages our UPS started the dreaded shriek. This was a simple fix and the UPS is back to happily chugging along, waiting for its time to shine. A better deal than the purchase of a new UPS that would cost upwards of $125.

Installed an electric start kit on my generator and needed a 12 volt battery for it, this fit the bill nicely.

Needed to be charged up first (arrived with almost no charge) but installed in minutes into my Generac GP7500E generator. Started up several times with the battery and works just like the original did. Hopefully this one lasts.

Perfect fit replacement for a jump pack that had died. This was half the cost of a new unit, so it made sense to just get the battery. Too early to see how long it will last at this point.

I needed to replace the original battery in my Cobra Jumpstarter / Powerpack and went with the Mighty Max as an upgrade. It fit well with only a small cutout to fit the terminals. It arrived fully charged and held the charge for 3 months when I recharged the unit. Pleased with my purchase.

Just the right size battery for my generator thanks guys..

Arrived over 90% charged. Just installed, so I can’t indicate about its longevity. As with every other SLD, there is no indication on the markings regarding manufacturing date, so it is left to hope the battery is fresh.
