Antigravity Batteries AT12-BS Performance Lithium Battery 12V with Built-In Jump Starter – High-Performance Lithium Powersport Battery for Motorcycles, ATVs, Lawn Mowers, and Scooters – 6.1 Ah

Using this battery in my 2004 Yamaha FJR1300 for a year without any single problem.I thought that the restart feature was more like a marketing gimmick, until I left my motorcycle with ignition switch and the headlight on overnight. Next morning, nothing was working, since the battery shut down, protecting itself against over-discharge. So I pressed the restart button, started the engine and left for a nice long ride.The only downside (of my motorcycle, not the battery) is I had to take a panel off to access the restart button. Perhaps a separate button option, with a small cable, would be nice to have.

I bought the AT12-BS Antigravity Lithium battery for my 2020 Ducati Monsters 821. I am not able to write a review on this battery as far as longevity goes as I just received it and installed it in my motorcycle. I can verify it was a perfect fit as it's near the exact same size/dimensions as the factory Yusa YT12B-BS. My factory battery was getting to be past age 3 and we have had a terribly hot summer and high heat is hard on batteries. This battery started my bike right up after install and it is more powerful than its lead-acid counterpart. Also weighs 2.4 lbs compared to 7.7 pounds but feels like weighs 10 lbs less.

So glad I went lithium! Although this battery, and the recommed charger are expensive (when considering lead-acid or AGM batteries), I think it is worth the price. I put this on a Yamaha FZ6R and it fires up, immediately, every time. With other batteries, some took two or three pushes at times, with this one there are no warmup turnovers, just immediate startup.Because I have accessories that place a constant drain on the battery, I bought the recommended CTEK charger, my "Battery Tender" brand wasn't compatible. This combo works so well, I have not had to test the reset function, so I can't comment on that, but having it makes me less worried when I don't ride and forget to plug in the charger for a few days.I have owned this battery around 4 months at the posting of this review.

I have a 2022 Ducati Scrambler 800. Unit worked great for a few months, I did notice my average voltage was quite a bit higher compared to the original Yuasa battery that came with it. 14v vs 13v on stock. (Installed this one due to corrosion on the stock battery) Suddenly my bike started to shut off randomly. Starting it again resulted in RPM going wacky and instrument cluster turning on/off rapidly. Bought another stock Yuasa battery and issue went away. Sent my Antigravity in for RMA and they called and said it was fine and they wouldn't replace it. So now I'm stuck with a paperweight that I don't want to put back in my bike for fear of being left stranded.

I bought this battery knowing that the lithium batteries would be lighter and because of the convenience of not having to go to the motorcycle shop. I did not expect how light it was going to be! When I received the package I thought a mistake was made. Even I thought it was some kind of battery store display model. It seriously weighs the same as a drill battery. After I installed it on the my it cranked it over no problem. It's been at least four HOT months since I installed it and have had no problems.

Works great. Even the restart button. I plan on buying the remote start dongle. Saves so much time, no need to remove the fairing to get to the button on the battery.

I have these in several of my motorcycles. I had 2 out of 5 fail. The 2 bad ones were either replaced uder warranty or refunded purchase. I just purchased 2 of them at same time and one was bad right out of the box so the bad one was refunded. When they work they are great. Would like to get another for my Duel sport bike but kinda leery about getting another one.

Great option for functional weight savings! Reliable under any circumstances!
