    High Quality OEM Brand Always Delivers
    Pros:- Rated for 270CCA, Testing concludes it is producing 404CCA which is absolutely fantastic.- Reliable Brand. YUASA is a standard OEM battery for MANY powersport manufacturers and is known to last a very long time and perform well.Cons:- Requires filling the battery with acid which is included and very easy to do.- Requires charging (at least in my case) after filling the battery with acid.- Cannot be oriented in any angle other than vertical.- Heavy and outdated tech.- No real WarrantyConclusion:Although there are many cons with this battery, the pros are truly worth it for anyone interested in a new powersport battery. YUASA makes arguably the best batteries in the business and they have a high-quality reputation to prove it.I'm a motorcycle mechanic and have seen hundreds of bikes that I've worked on that still have this OEM YUASA battery installed from the factory and it still runs over 8-10 years later in some cases.They are pretty bulletproof batteries and even tho it's still the same-old lead-acid style and not lithium ion or GEL, it still works wonders and does the job flawlessly. It really is worth the price in the end. If you found this review helpful, please indicate it below by hitting the button. Thanks!

    I have used these for years and decided to go to a different brand. Well, I'm back in the Yuasa family. I was getting 2-3 years max out of the "other" brand on my ATVs. I have a few toys I use these on so I put dates on the batteries. i have one of these that is still going strong from 6 years ago. SPEND THE EXTRA $20. Great product

    4.0 out of 5 stars Good AGM battery for my ATV
    Reviewed in the United States on December 16, 2023
    Style: BatteryVerified Purchase
    This battery lasted for 5+ years so, I replaced it with this identical battery. AGM battery holds charge much longer than flooded battery while not in use. So, this battery is good fit for ATV since I use it just every so often. The only drawback is that when you have more than 1 wire being connected to the terminal the connection becomes more cumbersome since the terminal screw does no reach the nut resting on the bottom of the terminal.

    After a wonderful call with Yuasa customer support they confirmed that the battery sold on Amazon are not the same batteries that they manufacture in the United States.

    Prior to buying these batteries from Amazon I used to get 5+ years out of a battery. Using the Amazon batteries I have now gone through three batteries and under three years.

    It is important to note that if you buy these batteries from Amazon, there is no warranty outside of what Amazon will cover. Amazon is not an authorized dealer.

    5.0 out of 5 stars Still the best lead-acid battery on the market.
    Reviewed in Canada on December 17, 2023
    Style: BatteryVerified Purchase
    This battery was very fresh when I received it because it was very active when I added the acid (acid pack included). It's very important to wait until the battery has cooled and properly absorbed the acid into the plates (1-3 hours min.) before the sealing strip is gently installed using only your thumbs. The battery should be room temperature when the acid goes in and room temperature when the the initial charge is applied, this needs to be done with a proper initializing charger, I use an Optimate 6 gold in the 14.4 volt setting until the battery is fully charged, your battery will last a very long time if you ALWAYS keep it fully charged using a charger with a really good maintenance/storage program like the one mentioned.
