    I would say this battery is as good as the original, if not better, we have used our block rocker multiple times since I put the battery back in, and it still doesn’t need a charge. We have a ION Block rocker, with LED lights, and it fit exactly, and was easy to install.

  15. Randy O.

    i bought this battery last year. i didn’t have the time to put it in my 4 wheeler so it sat on the shelf all winter in my cold garage. along came spring and i finally installed. the quad started right up. Great battery.

    I replaced my Rock Blocker Max battery after 3 years of hard use. It was super easy to switch out, and the new battery is amazing. It came fully charged. I’ve been using the Rock Blocker Max periodically for several weeks and it is no where near empty. Don’t hesitate to buy this item.

  17. William E.

    Perfect fit, solved the charging problem instantly.

  18. Cornell L. P.

    Great power & long lasting.

  19. Jesus

    I used this to replace my ion block rocker max battery and it works like a charm. It?s even better than the original battery.

  20. Jack

    I did not buy this battery for the Ion Block Rocker. Instead I bought it for an electric scooter of mine to replace a 2 year old 6.5 Ah battery and now it works very good by lasting longer.

  21. Luis Mares

    Really good battery, i used for my Ion max speaker, it’s holding charge really good. Thanks

  22. Reagan Owens

    Received it quickly and worked great!

  23. champ

    Fit in my block rocker no issue. The original battery is wrapped in rubber so it?s a little loose fitting. I cut a couple pieces of cardboard to fill in the gaps and all is well. I had the extended battery which was 7.2ah and this one is 9ah so curious to see how long it lasts.

  24. Branden B

    This Battery is a good replacement battery for the Ion Block Rocker.

Mighty max brings the battery backup back.
Arrived well packed in unopened sturdy box. Was replacement for identical Mighty Max battery I ordered 2 years ago. Taking 1 star off because didn’t include the needed terminal clips - was able to use the old battery’s clips
Same model fits in each of our four wheelers great product
Replacement for my Murray MT100 riding lawnmower. Murray does not make replacement batteries and you are on your own if the battery goes bad. Bought Murray MT100 in 2023, battery went bad in 1 year and all other Murray replacement batteries are LARGER so it won't fit.This Mighty Max Battery fit the MT100 fine and it starts it perfectly too.
Direct replacement for generac portable electric start generator. Works great.
Received really quick. Boxed well and fit great. Worked like a charm! I would definitely recommend this battery.
As an athletic trainer I rely on our water units every day to provide the water to our athletes. We have over 900 student athletes enrolled, and these units get used daily, so it is imperative these batteries are reliable. On a side note, I also use these batteries on my fishing kayak to power my fish finder. I can use my fish finder for about 20 hours before it turns off. These batteries are great! Highly recommend. I have not had any issues so I haven't spoken to customer service yet, but if they are as good as these batteries have been, I think I am in good hands.
Needed a replacement battery and the manufacturer wanted $50 whereas you only required $20. Made it worth it!
satisfy with price and easy installation.
Arrived in great condition comes with the bolts to attach the wire over all very satisfied
