I got this battery for my yamaha big bear 400 and so far it hasn't let me down, it has easy to follow instructions and is very simple to install you will have to fill it up with the supplied acid then charge it up. I charged mine overnight and in the morning I went to start my quad and it fired right up without hesitation. I HIGHLY RECOMMEND IT.

Worked well but fully discharged after 2 weeks of not riding. I was able to revive it so it holds a days worth of charge. If you buy you need to keep it on a trickle charger. Honestly I recommend spending more and buying a lithium battery.

Excellent battery so far. The previous owner had an agm battery in my bike, it felt like 4-5lbs. I was looking to save some weight and I'm happy I went with the Shorai, its just over 1lb and fit perfectly. The cost isn't a factor when your getting a reliable, stronger product and saving significant weight in the process.
