Delivered on time and expected!
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!
Arrived on time. And was exactly what it was described. Exact match
I am really pleased with the performance of the MIGHTY MAX BATTERIES I purchase to replace the ones that came on my RYOBI Zero Turn Mower.
From Amazon.ca arrived on time
It arrived quickly and was ready to use.
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.
The battery arrived in a timely manner.
