Best deal on Yuasa batteries on the Internet.

These batteries are good quality replacements, but probably won't last like a Yuasa. I had to have mine replaced not long after purchase and Rocky Mountain did a good job of taking care of me. EVERY Yuasa I've ever had has been a good battery and lasted well. If you can afford it, step up to the expensive Yuasa battery and you won't regret it.

Works great, but one thing they you should now that they don't include in the description: It will take almost 2 entire containers of acid. Also, shop around for the acid. I paid over $13 at Napa before realizing I needed two of them. Advanced Auto Parts had the exact brand for less than $7 otd.

Purchased this for my Vulcan 900. This is the heavy-duty version and is $20 less at RMATV than on the Shorai site. Lighter and smaller than the stock lead-acid. Bike fired right up after install with no problem. Fired up the bike after a cold night with no problem. Spendy for a battery but I'm happy so far. Hope it lasts for many years.
