Yuasa YUAM320BS YTX20L-BS Maintenance Free AGM Battery with Acid pack

Great battery,perfect fit,easy to activate, and reasonably priced ; like 80-100 dollars cheaper than the performance stores ! Delivered in two days !

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.

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 - Heavy and outdated tech.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!

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.

I bought two of them march 2015. One does not hold the charge and the other works a bit more than not.. Going to order another one to replace the one that does work and I'll see how long the other one last before buying another.. Both skis are identical and both are always connected to the batter charger.. Skis are 2020 models. Amazon does not take returns for batteries.. I lost my money.

Battery works great for an 2008 Goldwing.

Works as promised. Starts up my Goldwing, without a hitch.

Absolutely fantastic product OEM perfect replacement for your jet skis and Sea-Doo’s or your side-by-side fantastic OEM product highly recommended

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.

Powerful and reliable at a great price
