Purchased the Mighty Max 12v 10 Amp hr YTX12-BS. Amazon said it would fit my 2012 Kawasaki Ninja 650. It fits in the spot size wise but it's too tall and won't let the seat safely fasten. I have to return the battery unfortunately. It was a really nice battery and priced well.

Bought for my sons 2023 Kayo Fox 70cc quad. Works very well so far. Fit great as well.

Great battery for an even better price. Don’t waste your time going to the big box stores. Just order the Mighty Max from Amazon. Easy install and perfect fit. Fired right up with no issues.
