    Perfect for Predator 9000 generator. Started it in a split second. So far no complaints. Tested it with my 200$ battery tester and it said it was 100% charged and all cells good. Ready for hurricane season now.

    This battery performed well, even just out of the box. With my limited use so far the battery is cranking up my 10K watt generator well.

    After accidentally leaving the lights on my ATV and killing the battery I placed my order for this battery. Dropped it in and instantly fired up the engine, no problem. I’ve been using the battery for months and have zero user issues. Reasonable price, perfect fit, working well.

The Ebay seller was very gracious and replaced the battery that failed after 11 months. Thank you for the replacement.
Marc McDermott
Looks good.

So far so good, came fully charged ready to go. For a TTR230. Will update later if there are problems. I treat my batteries well. Bring them in the house over winter when not in use and charge them periodically. So it would have to be a manufactures defect or poor quality if it doesn't last five years.

Purchased from Amazon. Shipped and arrived timely, as expected. Perfectly fit my CyberPower ur700 just as Mighty Max said they would and they brought my CyberPower back to life.

I purchased the Mighty Max Battery YB12A-A for my 1982 Honda CM450E motorcycle. The battery arrived in excellent condition and was fully charged. It fit my motorcycle perfectly. After installing the battery it turned engine over like the bike was new again. I am looking forward to the upcoming motorcycle riding season. This was a good purchase.
