    • Genuine Yuasa quality, strong cranking power, and dependable performance
Style: Battery
The Yuasa YTX20L‑BS delivers exactly what you expect from a premium AGM battery. The acid pack is easy to use, the sealing process is clean, and once charged, the battery provides strong, consistent cranking power. Fitment is perfect, and the build quality is noticeably better than the generic replacements you see online. Voltage stability is excellent, and the ATV fires up. This lays on it's side in a Can-Am and after following the instructions for side loading, zero leakage. Yuasa’s reliability track record is the main reason I chose this model, and this unit lives up to that reputation. It’s a true maintenance‑free AGM once activated, and the peace of mind alone makes it worth the price. If you want OEM‑level performance without gambling on cheaper off‑brand batteries, this is the one to buy. ... show more

    • Really a new battery!
Style: Battery
I love the way this battery come with the acid in a separate container. This way it can be new when I fill it. It takes a while to fill and absorb before charging but it seems like a great way to get a real new battery. I think it'll last a long time.

    • 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. ... show more
