    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.

This is my second mighty max awesome batteries for Minnkota trolling motors
So far so good with this one!!!!
Liked how we got it in a timely manner...no problems with the package...
Excellent 9ah SLA battery. Much cheaper than a replacement 2.7ah battery for my old Amazon Basics UPS. Didn’t fit in the original case naturally, but I had already planned to us a short extension cable for the 12v leads. Only using the ups to power overhead LED strip lights, so 9ah should be more than enough to let me see when the power goes out.
Arrived on time and in great condition
