    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.

    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.

    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.

    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.

    replaced the battery in my block rocker, this lasts even longer than the original. I just bought an extra one, now when i head out for the weekend i just bring the spare and swap it out without having to recharge.

Cool looking battery., will be placing in a Pontoon Boat soon. 👍
Received the replacement ML4-6 battery for my Coleman lantern and it was an exact match. I’m very happy with the battery and it works as it should. Update, ordered another mighty max battery. This time it was for my battery backup. Exact for and extremely easy to swap out. For $20 i got my $80 backup working again. Thank you mighty max battery another satisfier customer with an excellent retutation, i highly recommend.
Excellent Product and Seller!!!
I placed it as you can see from the old to the new on my EverStart Jumper as you can see in the pics it fit perfectly and I gave it a 24 hour initial charge on my house outlet with a thick orange cable and as I tried it it worked perfectly in all functions, I woulkd give it a 100% Excellent Recommendation!
I had an old harbor freight 3 in 1 auto battery jumper that no longer would hold a charge. This ML 18-12 MIGHTY MAX REPLACEMENT BATTERY, fits exactly as original and is holding a stat of charge greater than 13 volts after first time charge. The photo is the old battery. I've already installed the he MIGHTY MAX and don't want to open again.
Packaging was very good.
Let's see how long it lasts.
Works like original
They are what I ordered and they came sooner than I thought then was told to me
New home rough but comfortable
Excited to try a GEL battery and hoping for extended Life in Florida. Engine starter spins like brand new.
Great Battery!
Great price! Heavy duty!
