    Did exactly what it was supposed to do. Switched battery, charged overnight and generator that had not run for a year fired up like a charm. Thanks.

    The Battery is an exact replacement for what fits into a portable air pump and jump started pac. The only thing I can point out is the terminals are facing 90 degrees from the original battery in my jump starter. I had knew the cables to the new battery would be no problem. So be aware of ter battery terminal positions.

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.
Perfect replacement for the battery in the LiftMaster garage door opener.
Great little battery. Perfect fit for Cub Cadet XT1 series. Came fast from Amazon fully charged. Started my mower on first crank.
Very quick service from Walmart. Have not installed battery yet, but it looks to be exactly what it says mighty max.
I took it out of the box put it in the motorcycle and haven’t had a problem yet
Installed and fired right up!
came as expected 4/1/26 by Amazon and works perfect
