    Just installed this battery on my new, slightly USED, low hours Generator. It fired the generator up quickly. I will edit this review in about 9 months and will report on how this battery holds up in the Florida heat. So far, so good.

  5. Rated 5 out of 5

    Very intriguing

    I have always had good luck with Mighty Max batteries. Some have lasted 6 years so that’s a great return on the dollar spent. Depending on the battery and application, the cost can be as little as $3 per year. Not bad at all. They are excellent batteries.

    I figured it would be cheaper to replace the battery in my 15 year old Xantrex powerpack 400 plus than buy a new unit. Decided to upgrade to the gel battery over the standard since it did not cost that much more and is a deep cycle battery. I was very disappointed to see the terminals were inboard on the battery I received not outboard like the stock photo everybody has. It was immensely difficult to connect the cables in the booster box since the cables were a fixed length. I had to dismantle the booster box and carefully bend everything so I could connect the battery and get the cover back on.

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
