    In addition to having the power to start most cars, this battery fits many of the ‘jump boxes’ currently on the market – no need to toss the box, just measure the old battery, and you may find this one fits perfectly!

    i thought this would be bad, but at it’s price it compares really well with the other brands this size, holds a charge well and without starting for two weeks as well.

    Battery size and spec are the same but negative and positive posts are in different locations then original battery will have to make a adapter to use. Great price if I can get it to work.

    Obviously we won’t really know until we’ve had it for a couple of years at least, but – so far so good. It is very slightly thicker than the PC680, so it’s a snug fit in a PC680 battery box but it does fit. It was fully charged right out of the box.Our old PC680 lasted about 9 years, but I was not encouraged by recent reports of their longevity. Of course they’re 3x the cost too. We’ll try this one and see how well it holds up. For the price, if we get 2-3 years it’s still a bargain. I will say it starts the engine better and faster than the old battery did… of course it was an old, tired battery.

    I purchased this to replace a ( yet another ) DEFECTIVE Odyssey PC680 that was about a year old. Good luck trying to get Odyssey to warranty anything- I’ve owned three of them in the last 6 years for two cars and I’ll never buy another. This inexpensive battery has been functioning in my CRX track car for over a year and so far so good- I drive the car occasionally ( at least twice per month ) and the battery seems to tolerate the inactivity pretty well. It’s not an attractive battery, but the price and performance have been very good.

    Advertises as a direct replacement for an Odyssey PC680, which it does fit in my BMW R90/6, but it barely will crank it. I made a couple of calls to the company to find out about the cranking amps, but could never get an answer. I was assured by a tech, it would be plenty for my bike.

Mighty Max Battery
Based on 4688 reviews
Good shipping on time
Bought this for a 4 wheeler that has set for years. Great purchase as I didn’t want to have to fill a battery with the acid
it came in great, sorry, i do not have a camera, and its working good
My go-to battery supplier for APC backup devices.
Quick swap. Out with the old in with the new
Well packaged, battery looks to be good quality, will install on the weekend and update over time. Got it on Amazon.
Arrived quickly, week package. Week put them to use quickly in Spain.
Love my monster music box and my 1st battery lasted a long time.
Had a Legend battery bought in January of 2024 that went bad wouldn’t start under a load. I have a 2005 Volvo xc90 V8 so the battery cranking is important. Ordered the Mighty Max through Amazon I was overnighted to me , delivered to my doorstep. Recharged all ready to go drop in and start, beautiful! Has a 3 year warranty with options to extend that warranty. How great is that!
The batteries were packaged well, and arrived looking good. Now we need to hook them up.
