Effective Battery
Battery was a great price, fit well in the space I needed it,and delivery came on time. It worked great for my needs, as I was able to mow my grass.

As good as the $100 powersports batteries for way less
Is a great replacement for the battery in my cub cadet zero turn. This battery was $30 ish compared to $100+ for a OE replacement. Exact same dimensions, came precharged, has been working great.

Works with Troy Bilt TB30R
I have gone through 2 factory replacement batteries for my Troy Bilt TB30R. The factory batteries are expensive and they do not last. Every winter one of the cells goes dead when it gets cold. This Mighty Max battery is about 3/8 inch taller than the factory battery but will work with all the Cub Cadet Mini Rider, Murray, and Craftsman 30 inch rear engine mowers. Installed the battery and it has plenty of cranking power--twice the cold cranking amps of the factory battery. This replaces batteries with part numbers 490-280-C016 490-280-F016 490-280-Y016 725-17136

Don't buy
Might Max 12 V 11 AH AGM battery (YTZ12S) gave 2 poor starts and a week later only 3 volts. Even the charger says it's finished. Tops at 10 volts and instantly drops down. Going back to seller for refund: not a replacement.

Good but CCA not accurate
Good battery but the CCA is overrated

Perfect fit for a Cub Cadet ZTS1- 42" zero turn mower.
Perfect fit for a Cub Cadet ZTS1- 42" zero turn mower. Batter YTZ12S was a perfect replacement for the over priced Cub Cadet battery 72517335.
