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. Read more
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! Read more

Received this battery today and immediately connected it to a trickle charger.. got home from work and installed it on one of my Honda Fury’s. (Man, Honda made that switch out a tough process - to no fault of the battery at all). It’s a great fit and a super great price. Works like a charm and no issues at all. Buy with confidence 👍🏼 Read more
