    I needed to replace the Sunnyway original battery in my MotoMaster Eliminator PowerBox power pack. The PowerBox doesn’t leave much play between the cables and connectors, so I needed to remove the grommet style inserts in the PowerBox in order to get the battery to fit. This is due to the terminals on the new battery being inset a little, compared to the original. I just purchased the battery, so I don’t know about the longevity of the battery, but the PowerBox does work and was able to boost a weak van battery, so that a neighbor could start his van.

Great Battery for the Ion Block Rocker Bluetooth speaker to make it mobile

This is the second pair of batteries that I am using in my Champion 8500 home generator. Manufacturer says replace batteries every two years in Floridas hot summer seasons. Had the first pair of these batteries installed over three tears and still start the 24v generator every time. Installed new ones because hurricane season 2026 started, and I don’t want to install the new ones during a hurricane. Best batteries I have ever had. First set from another company barely made it two years. Go Mighty Max!

I had to replace the battery in my back up generator. Purchased the Mighty Max on Sunday. Delivered on Monday. Installation in the generator was a breeze due to the perfect size and correct terminals. I’m confident this battery will last for years to come and will make powering my home easy when power goes out.

Great price, arrived as promptly and made in the USA.

Delivery was quick from Amazon and the 2 batteries I ordered for my wave runners fit exactly. We'll see how they do this summer as we use them. Attached photo of one installed.
