Perfect fit for Litter Robot 4
I bought this Mighty Max Battery 12 Volt 1.3AH battery after looking into the one Litter Robot sell on their site for $40. The dimensions are very similar and importantly its a 12 volt 1.3 AH battery. The fit is perfect, and was quite easy to install. The attached photos show the little robot 4 after removing the 4 screws (marked in yellow) that cover the motor mechanism. They have instructions on their site, but its dead simple. After unscrewing the cover you can see the wires for the battery. Attach red/positive to positive and black/negative to negative and ensure the terminals are at the rear of the robot, tuck the wire behind the wire holder and screw it back in. This is GREAT value for money for this specific use case, and generally speaking is a good value for a small 12v battery. Given this application, I don't know about battery life or charge rate, this is not something I can measure. For a quarter the price I could replace this more often if needed, but I suspect this will work for several years at a minimum. Solid 5 star product

Works in the Litter Robot 4
Someone on Facebook recommended this battery for the Litter Robot. I purchased this battery for my Litter Robot 4. The one from Whisker is $50. This is the same battery and a whole lot cheaper! Easy to install. Now when the power goes out The Lotus Palace will still be working just fine!

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...

Not an EXACT fit.
It was sold to me a replacement battery for the Amazon Battery Backup 400. Smaller than the original, but we will see if the thing will stop beeping when it is unplugged.

Not powerful enough for Litter Robot 4
Purchased for use in Litter Robot 4. Size is correct. However after installing and fully charging, battery does not have enough power to run a single cycle on the device.

Smaller than I expected but works as a quick fix or testing small devices.
Bought this battery to test and setup/program my fish finder when not on the boat. Worked well and didn't drain in a half hour like I was expecting. It's perfect for small items that require a 12-volt battery, but I wouldn't plan on using it for my fish finder longer than 60 min or more. Not a ton of power but enough for what I needed.

Battery for Toro mower #21464
Needed a new battery for my Toro mower, model #21464. This battery fits perfectly in battery box and will easily start mower. Other batteries too large to fit in this model. Price is much cheaper than original battery. 12volt 1.3ah plenty, but may have to charge more frequently, we will see!
