## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value
*by S***F on August 31, 2025*

Put this one into a Yamaha VStar 1300 where the battery refused to charge. This battery was easy to install, and my motorcycle works again like a charm :) Make sure to bring any battery you replace to a recycling center!

### ⭐⭐⭐⭐⭐ AMAZING BATTERY FOR THE PRICE
*by A***R on September 1, 2025*

For a 2016 Indian Scout. YES it fits. It's a bear getting the feeds on. That has NOTHING to do with the battery. That's on Indian for bad cable management. Just be prepared to be calm, and take your time. :)Battery is a beast! I can't believe you can get a battery this good, hassle free for this price! Would buy again for sure. Rather just get a new battery each year honestly!

### ⭐⭐⭐⭐⭐ Replacement for MX14-4 Battery on Husky Snowblower
*by E***R on September 10, 2025*

This replaces an MX14-4 battery in my Husqvarna ST24 snowblower. It fits well and starts the Husky right up. So far, so good. The supplied nuts and bolts used to connect the battery cables are kinda fussy to install, especially in the tight quarters of the Husky battery compartment. I’d rather see the battery terminals threaded to accept the bolts but maybe theyre too soft? Anyway, I got it installed. Hopefully I’m ready for winter. We’ll see how long this battery lasts.
