    This is the second one of these that I have purchased for use in my experimental homebuilt airplane. The originally intended battery which retails for $100+ more than this one is the PC-680. This is a drop in replacement for the PC-680. Has never failed to briskly start my Lycoming 4 cylinder 180 HP engine. I have dual alternators installed so once the engine is running I don’t really care what happens to the battery. If I only had one alternator and needed to rely on the battery for back up power if that single alternator ever failed, well then I might find value in spending 3x’s the price for a battery with a better pedigree. At this price it makes sense to simply replace the battery every year or 2 before the performance starts to get soft, I always have an almost new battery installed.

    This was the exact part number of the battery in my Troy-Bilt generator but the positive and negative were switched I had to put new cables on the generator to make it work I cannot rate the longevity because I’ve only had it a couple of weeks

    I like the top screw down post so I only have to use a screwdriver to attach terminals. It is much easier than attaching with a bolt and nut.

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.
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.
