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 - Heavy and outdated tech.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 Warranty Conclusion: 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!

Great batteries.
I have used quite a few of these over the years. They last quite a while and are worth every penny compared to some other battery's out there. Quick and easy to fill. People saying it's a pain to fill and charge probably shouldn't be changing a battery out in the first place. I like the fact it needs the acid added that way you know you're getting a fresh battery that hasn't been sitting around. Highly recommend this battery.

Some hassles, but GREAT battery!
I ordered this battery from DVolt Batteries via Amazon. The battery arrives un-activated. That means that you have to fill it with sulfuric acid and then charge it. Sounds fairly easy, just realize that it takes quite a while before it will be ready to use. And Sulfuric acid is kinda scary stuff to work with. The battery arrived quicker than expected. Brownie points for DVolt for very quick shipping. The acid is actually very easy and safe to use - it's in a container with six cells that match/line-up with the battery cells exactly. you align the acid cells with the battery cells and press down, the battery will puncture the acid cells and then the acid flows into the battery. Slowly. This takes over half an hour, closer to an hour. After the battery has been filled with acid, you remove the empty acid cells, place a permenant cap on the battery (make sure you line it up exactly), then let it sit for a coyuple hours. Next, check the voltage - it will be low. There are guidelines supplied by the manufacturer. finally you have to trickle charge it, basically overnight. Next day you're ready to go. My bettery came slightly damaged in shipping. I didn't notice the damage until I was ready to install it. I let DVolt know via Amazon and they were very good to work with. It took a couple tries to get the problem resolved, but I now have a good, functional battery. Another brownie point for DVolt. I have another YUASA battery, the same model, and it's performed flawlessly for 6 years now, even sitting outside one Minnesota winter. I love these batteries! I don't care much for the mail order activation part of it, but it's really not that bad.

Can't Keep a Charge
I bought this battery for my Seadoo GTI. I followed the instructions, put the electrolytes in, and charged it. When I put the battery in my Seadoo, I was getting iBR fault errors like crazy and my iBR wouldn't work. After a day of troubleshooting, I took the battery back out, charged it again. This time my Seadoo worked properly, but it was too late and I couldn't get out to the lake until Friday. 5 days later, I tried to go to the lake but this damn battery was dead again! This is a brand new battery and should not be dead from sitting for 5 days. My Continental sat for months without an issue. I will never buy this brand again or a battery from Amazon again. I knew better but did not trust my gut. Always buy locally!!!

Pretty Amazing Stuff
Well - my first self installed YUSA electrolytes battery was a great success to my surprise. The plastic fill bottles and seals all looked kind of flimsy but in the end it all worked out quite well. I measured the voltage upon receipt and it was about 4.57, installed the electrolytes making sure I got all of the fluid in the cells and five minutes later it measured 12.57. My 5 year old battery was measuring less than 11 and struggling. Seems all of these are good for about 5 years if you are lucky. Just make sure you get the cap seal back on there even with the top of the battery - that was a bit touchy - use your hands no hammer. The bottom of the battery gets hot upon electrolyte fill. Thanks to Amazon for the quick ship to my house via UPS. I am an original Prime member and plan to stay that way!

Excelente bateria! La compre para un Can Am Defender y funciona muy bien. Igual a la que traía de fabrica. Recomiendo.

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.
