    Disliked the positive and negative terminals being located next to each other. Had to elongate the negative terminal wire to make the battery compatible with my generator. However, the battery is powerful and starts the generator easily.

    Used this to replace the battery in my Champion Electric Start Dual Fuel Generator and its fired up first time without issue. Swap took 5 min and I was back up amd running. I previously put a pair of extension battery leads and quick disconnect spade terminals on it so I can quickly disconnect after use. The original leads may be a little short as these terminals are on the right side of the battery and not the front, this I cant confirm because I modified mine fro the original config. But it is the right voltage and amperage.

    I got this battery to run a home generator. When it arrived, it was suggested that we charge it before use. My husband did not wait, but put it in the generator and tried it out. The generator started and he has been using it since. I would highly recommend this battery.

Just received my battery I ordered from Amazon. Haven’t tried it yet in my ridding lawnmower. It was in the original battery box inside another box from Amazon and had no damaged .
GREAT HAVING THE HANDLE TO HELP GET INTO ITS NEW HOME
Good battery can’t wait to put it in my second Kawasaki kfx450R atv
Came quickly and seems to work good but negative post was bent and couldn’t get the bolt in the hole without drilling it out.
Battery just arrived. I placed it on the maintainer and it showed that the battery was practically fully charged. Looks good, looking forward to installation.
Purchased as direct replacement. Original was on a used DR Chipper I purchased, I used it several years before it expired. Trust the replacement las as long.
Looks ok
Ordered 2 Mighty Max Batteries from Walmart. They arrived by FedEx 3 days later. Right to my door. The Golden Patriot is back up and running like new.
Very good for the price, I have used before and worked fine
Battery arrived perfectly fine. Already installed in my JNC660. Works great!
