I got this for my champion 3500 generator. It is much smaller than what I had. I got it and put a trickle charger on it and it was charged. I just hooked this battery up and it cranked my generator up great. So far so good.

These battery 's are so light weight, I didn't think they would even work, but they are fantastic, I am very happy with my purchase of them.

The media could not be loaded. I used this Acoucou YTX4L-NA battery to replace my YTX4L-BS battery in my daughter's 4 wheeler. The very first thing I noticed was that this battery is WAY lighter. The battery is exactly the same size as the one I replaced. It does start and crank the 4 wheeler no problem. The issue I'm having is the included hardware isn't even close to the right size for this battery, and it's not the right size for something that is supposed to use the YTX4L battery size. The bolts are too big, and with the built in washer and lock washer, they are not long enough to start into the included not that is supposed to go into the battery post area. The nuts that were included are also hex nuts, but these style batteries use square or rectangular nuts so that you can slide them in, they stop themselves, and you only have to worry about the bolt head on top. The hex nuts simply spin inside the battery post, so you have to get something in there to stop it from spinning and a wrench doesn't fit, and a socket won't fit, so you're left basically using a flat headed screwdriver to try and wedge between the nut and the inside of the battery post. Having limited room makes this almost impossible, and even then, when you do get it, you can't really torque it down very tightly. You really need to replace the hardware, and it's more of a specialty size, so it's hard to find. The next issue is that the bolt is too big, so for something that is supposed to use m4-m5 bolts, you'll need to replace the ring terminal on the wiring if you want to use the included hardware, but again, with the lock washer and the regular washer, you'll still need to get a flat blade under it to space it up enough to get the threads started, then move the screwdriver to the side to wedge it to try and get it tight. The installation trying to get the hardware to work, and then trying to swap the old battery hardware, was so aggravating and the worst part about the whole battery. In the end, I was able to get it to work, but I had to go to the local hardware store and spend another $6 for a couple of square headed nuts that would fit, and then the matching bolts. I gave this 4 stars because the battery does work, and my issue is mainly with the hardware that it uses and comes with. I would really like to give it 3.5 stars, but rounded up because I can only rate it in whole stars.
