    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.

12V 9Ah SLA battery for my solar backup and USB charging
I bought two 12V 7Ah F2 terminal Mighty Max batteries to replace aged APCRBC160. After installed them in my APC UPS, i run apctest to reset battery date and tested for 15 minutes with 15% load and run apcaccess every 30s. The BCHARGE from 100% to 60% and TIMELEFT from 40 minutes to 30 minutes, which is perfectly expected. Hopefully they'll last 3 more years.
