Mighty Max Battery YTZ10S -12 Volt 8.6 AH, 190 CCA, Rechargeable Maintenance Free SLA AGM Motorcycle Battery

Arrived charged and able to start my bike. My only slight complaint would be that the mounting nuts they send with this battery are sort of hard to work with, they're very thin and are not easy to keep in place as you are putting the battery in. The simple solution is to just keep the mounting nuts and bolts from your previous battery and use them on this one. That's what I did. But depending on the mounting location, you may not have a problem using the hardware they send. (Installation suggestion: if you're putting this under the seat of a motorcycle, where a lot of batteries go, the battery often isn't completely level and that's why the nuts keep sliding out. You can use a small piece of electrical tape rolled up so it is sticky on both sides, and stick the nuts under the battery terminals so they don't keep sliding out of position as you put the battery in. You can just leave the electrical tape there when you're done, there's no reason to try to get it out.) Regarding the size, this battery is physically a little smaller than my bike's OEM battery, but a smaller battery isn't generally going to be a problem, it's a bigger one that you have to worry about because it might not fit. Also take note of the orientation of the positive and negative terminals, which need to be the same as those on the battery you are replacing. If the size is right and those things check out, I would say this battery is a good value and worth considering.

Bought this to use on my Jon boat to crank my Predator 224 mud skipper motor. Works just fine! Looking forward to a good run with this battery. If anything changes I’ll update!

Used this in my 2021 KTM 890 adventure. Fit right in the box but it was about an 3/4 to an inch too short. I had foam battery packing to make it fit luckily. Started right up and the bike seems happy

I paid $112 for this same battery at Walmart for my generator, and purchased this one the same day, to make sure I would be prepared for the upcoming bad weather. It was literally on my porch less than 24 hours later and I was able to return the other battery to Walmart. Incredible value compared to anything in store especially since there is no core charge, and you can buy 4 of these for what they sell one for at Walmart, and since Walmarts warranty is only 3 months for these batteries, it's safe to say this battery is 4x better! If it lasts at least a year it will be the only way I but batteries from now on!

Normally I have good luck with mighty Max batteries but this one was just plain dead. When you're shopping for a good battery always buy new and don't be like me and buy one off of Amazon resale just to save a few bucks. The one I received had a smashed terminal, was deader than a doorknob and held no load charge whatsoever, and also came with no hardware for installation. Normally you can't return lithium ion batteries but for some reason I was able to and that's exactly where it's going so I can spend my money on a different brand, emailed mighty Max And they stated that there was nothing they could do because I bought it from a third party and not them directly.

I work for a high school marching band and you'd be surprised at how often we need to maintain the items that we own and how often we have to look for a good deal on parts and materials and hope that what we got will hold up as well as another option. I bought this battery because the warranty was just as good as the original battery for our Honda EU3000IS generator that we use to power our synths, mixer, amps, wireless system and so much more for our competitions. The generator has the pull start, but when dealing with a lot of high schoolers the key to start system is much easier. But the battery that the generator calls for is $150 from Honda or their authorized repairers or $120 on amazon. But I bought this one for less than a third of that and it was direct plug and play. Fit PERFECT. Starts no problem. And it has a warranty. I dont think its possible to go wrong with this item at the price.

Eazy to install, comes charged, starts the bike right up! Installed on my 2018 Ninja 650

Unhappy with life of battery; using in a Honda 3000 generator which his rarely used; dead as of 1/21/26; less than 13 months since purchase.

It does fit 2009 Honda CBR 600rr as well as 2014 Yamaha R6 I have bought two and im very happy for the price and it does work for me ready to go easy installation you cant go wrong with under $50 bucks a peice i gave it a try by looking at the image and worst case If it didnt fit i was going to return it so far so good. No complaints lets see how it goes for this season...

Hasta el momento me ha funcionado muy bien. La recomiendo, buena calidad a un precio accesible.

The information on battery was correct and works and fits just right. Very happy

Mala batería, no sirve, no compren garantía extendida, no se hacen responsables, te traen vuelta y vuelta y sólo evaden responsabilidad. No lo recomiendo!!

This battery has a very short life span and will start declining as soon as it is put to use. My previous MightyMax battery only lasted 2 years before not being able to provide enough CCA to start my bike (2018 BMW S1000R). I've only had this one for 2 months and it is already down to 90% state of health and about 170CCA. It's a cheap battery and you get exactly what you pay for.
