Essential Item and Great Value
Only time will tell if this replacement holds up better than the lousy battery that came new with the mower. That original battery did the job well and held enough charge to start the mower every two weeks all through that first season. But, after sitting for several months during the winter, it didn't hold enough charge to even crank the mower the first time we tried starting the next spring. Not a big deal since it also has the usual recoil pull starter and we haven't gotten too old yet to use that. But having the key start is nice and having the original battery no longer holding or building much charge after just one year was a disappointment. So, we're eager to see if this one does better. It fits, it cranked the mower instantly the first time I hit the key. Now we'll see how well it holds charge between uses. There are battery maintenance chargers available. But, there is no recharging port on the mower. You have to take apart the battery box to plug the battery into any charger you buy. Just not worth the trouble except during the winter when the mower is not being used for months; especially when there is always the pull rope as backup. Whatever you do, if you buy a charger, buy it here or some place like Harbor Freight Tools where you can get it for under $20. If you look it up on the Honda website, they are asking OVER TWO HUNDRED DOLLARS for it. Has to be a pricing mistake but until they fix it...

Litter-robot 4 compatible
This is the same battery litter-robot sells for $40 on their website. Save money and buy it here. Works great and installation is easy. They also offer a 3 month extended warranty when you register.

Perfect fit for the original
ML1.3-12 - 12 Volt 1.3 AH SLA Battery - Mighty Max Battery Brand Product We bought this battery to replace the one in our lawnmower, not in a battery backup UPS as a lot of the applications seem to fit. This was the exact part number on our original one in our self-propelled more, and the battery fit perfectly and works well to start the mower. The original one lasted about 2 years, which I figure is about right considering we live in Florida and it's hot as the Dark Side of Hades down here, considering we get a lot of sun. if you need to replace your original battery, whether it's in a UPS or Mower, and it happens to be this part number give this one a shot. It seems to work just great for us.

I use it as a testing battery for projects, I have killed it down to 10v twice and it always charges back up. I froze it for half the winter down to -51c and it still works great. I’ve dead shorted it, ran light bars off of it and lots more. It’s not often that I am truely impressed by a product. High quality, good performance and cheap.
