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.

I bought this for the electric start on a portable generator. Once fully charged, I connected it to an Ancel battery tester. The first test showed 156 CCA. I then attempted a 5 hour, 2 Amp constant current load test with a 10.5 Volt cutoff. The datasheet doesn't show a 5 hour rating and the 10 AH is likely based on a 10 or 20 hour discharge. The first shutdown was at 4:25:15 and 8841 mAH. I reapplied the load several times as the voltage recovered to 11.2+ Volts. The final time was 4:50:34 with 9675 mAH. I like the battery but find the performance data lacking. I contacted the factory and they responded the next day. The datasheet they sent, didn't match and didn't have the curves or tables that I wanted. By adjusting the 5 hour data for a ML9-12 battery, I would say this battery does better than spec. After recharging the battery, I checked it twice with the Ancel tester. 160 CCA both times. The battery is installed in the generator and provides plenty of cranking power. This battery is also the right size and has the proper terminals for H.F. generators. The shipping box should have had sone filler to keep the inner box in place but it arrived undamaged. Edit 12/05/25: I replied to the company Email, thanking them for the datasheet, but noting that it didn't match my battery. They responded the next morning with the correct sheet. The 10 AH rating is based on a 1 Amp , 10 hour discharge to 10.5V. You can't beat their responsiveness!

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!

Using it in a 2016 Honda PCX 150. Fired bike right up. Smaller in height than OEM. Fits compartment area, but height is about an inch shorter, so a block of wood was used under to make up difference. Installation was extremely frustrating in my use case, since the battery is angled in under the seat, and the included hardware screws were too short to start threading the nut. Nuts are also too small for under terminals, so they were constantly sliding around, thus misaligning nut and screw. That frustration alone would probably stop me from buying this battery again. Longevity/durability is unknown at time of writing. It's 6Ah vs OEM's 7.4Ah, and CCA is listed as 130 CCA vs OEM's 120 CCA.

Excellent battery for my hawk 250 works great and pretty reliable

Excelente desempeño en mi NMAX 155, tamaño preciso, calidad y precio, estoy muy satisfecho.

Great fit for my Triumph Tiger 1050. Has a few more cold cranking amps than standard, works well.

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

The delivery was a little bit late, actually Two hours behind the promised time, but still acceptable. The battery working well so far, it just started.

Très satisfait
