Fits cub cadet z50
Size: U1-S-400
Works great for cub cadet z50 Kawasaki engine. Tykool wants you to check charging output and mine was 14 at full throttle. Love to push button Volt meter built onto battery. Does come with terminal nut and bolts. Which was a question I had when ordering.

Tykool battery failed to last 4 months
Size: U1-S-400
This battery didn't make it 4 months and I have used two differnent Noco lithium chargers to try and get life back into it, chargers show green full charge but the battery says 54%, put it in my John Deere Gator Diesel 6x4 and it will not turn the engine over and the battery goes to zero. I am currently trying to get a hold of Tykool because of the 1 year warranty and no luck so far. More than likely an aggravating loss!!

Lots of Power
Size: U1-S-400
Very light weight, I didn't' expect that. It has digital meter between the terminals. As soon as I hit the starter my 21hp Briggs jumped to life. No slow cranking - spins very fast. I really like it.

Things to know
Size: U1-S-400
It showed up 100% charged and is very light. It easily turned my riding mower in over. Seems like a great battery but only time will tell. You have to pay attention to your riding mower charging system. I checked mine with a battery tester. I have a John Deere X320. It showed it was within charging range at first but it crept up to 15 volts. I went ahead and mowed anyways for like an hour or so. After mowing I did the test again and it was within range at 14.5 volts.

Much lighter than the lead-acid battery it replaced
Size: U1-S-400
The first thing I noticed when installing this was the weight. After years of wrestling with traditional lawn mower batteries, this one felt surprisingly light when lifting it into place. I was replacing an aging battery in a riding mower that had started becoming unreliable after sitting between mowing sessions. Installation was straightforward since the dimensions matched the original battery, and I didn't have to modify anything to make it fit. Once connected, the mower fired up immediately. No sluggish cranking or hesitation, even after the mower had been sitting for a couple of weeks between uses. That's probably been the biggest difference I've noticed in day-to-day use. The terminals feel solid, and the housing seems well put together. While I can't speak to long-term durability yet, it certainly doesn't feel cheaply made. The main drawback is price. It costs more than a basic lead-acid replacement, which buyers will need to consider. That said, the lighter weight, strong starting performance, and potential for a longer service life help justify the extra cost. So far, it's been exactly what I wanted: a direct-fit replacement that starts the mower without issue and makes battery handling a little easier whenever maintenance time rolls around.
