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.

This was a drop in fit for my 2006 Yamaha R1 and I’ve had it installed for about three months now riding on a regular basis and have had no issues with it. The last battery I installed in May of 2025 only lasted a year despite keeping it on a tender when I was t riding in the winter and it cost over $100, so if this one lasts a year or more I’ll call it a bargain!

Doesn't hold charge

Cheap.. but so far pleasantly surprised. The only bad thing about it so far was the terminals made it hard to install - they are basically bare piece of metal. Besides that, my motorcycle has been fine with it. It holds charge and I trickle charge it every week or two and it's still going!

What a deal .. fitted perfectly on my R1.. terminal polarity was setup the same as my oem yuasa that it replaced And started right up like a champ

Is a Good batery

Fits in the stock battery box of a Honda Shadow 1100, good cheap alternative to the “T” shaped battery’s that have a lower CCA capacity this one is 190CCA it starts that 1100 V-Twin right up Ive also had good luck with these batteries and their lifespans the last onr i had for over 2 years before i sold the bike with it, gotta love Mighty Max batteries

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.

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...

Parece que todo bien , solo falta instalarla y ver que funcione bien.

It works.

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

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