Antigravity AT12-BS Performance Lithium Motorcycle Powersport Battery with Built-In Jump Starting, 12V 6.1Ah Replaces YT12, YT12BS, Scooter, Lawn Mower, Generator Battery - Ducati, KTM, Yamaha, Kawasaki

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.

My 2016 GSX-S1000 came with a FT12A-BS sized lead-acid battery and looking at the dimensions, I figured this would be a fine fit. It was very close -- the increased height basically leaves no room for the terminals to connect. I was able to squeeze them into a nook next to the battery, just barely. The positive battery cover had to go (replaced it with tape) in order for the seat to be installed properly. Anyway, bike started right up, and saved a few pounds.

My only beef is with my particular installation on a 2008 Triumph Speedmaster. I originally ordered the ATX battery which was supposed to fit. However with the way the battery drops into the tray, there needs to be a notch on the top as the lead-acid counterparts have. So I ordered this one that's thinner and it's not an exact fit but perfectly fine. Be sure to order the battery tracker - you get an app that connects via bluetooth. This gives not only a great way to monitor voltage, but also cranking voltage and a charging system test. Having had numerous electrical issues with motorcycles throughout the years, this is absolutely awesome to have. You get peace of mind on road trips that your battery is not going to fail. But even if it failed, this battery will never leave you stranded! It will always kill itself and leave you enough juice to start the bike one more time. The only way you are stranded is if it dies and your charging system is toast for some reason. In my climate, I am able to just leave this battery in over the 3 cold months of storage per year. It will not deplete like lead-acid does. Won't need trickle charging. I contacted customer service and they just recommend I disconnect the negative so accessories won't drain it. But even if they did, it would kill itself and I could just use the Re-Start feature to jump it in the Spring. Can't recommend this battery enough. Even if for some reason, it doesn't last as long as advertised, I would buy it again just for these awesome features.

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 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.

I will update this if it doesn’t go as well as I think it will. First the battery lugs are stainless steel, no square nuts, instead 3/8” stainless square stock is threaded and you can easily stack 1/4” of lugs and still be able to thread in the bolt without needing to do tricks to keep the thin square nut of normal batteries high enough to get engagement. Also this battery was still half the weight but was tall enough that the strap securely held it in place without any foam pads to take up space. I’m already a victim of one li-ion battery leaving me stranded on the side of the road with nothing to do but wait for help, so I was and still am apprehensive about them, I don’t understand yet how my motorcycle will charge it with out damage, but my normal trickle charger will. If there’s a battery balance and charge controller in the battery a led acid charger should not damage it as the power is the same as my alternator on my motorcycle. It’s been almost a year but a very cold winter, I pulled out all my lead acid batteries out and placed them on chargers, BUT not this one. After sitting in my garage all winter I uncovered my bike and it started right up. I did put a gallon of stabilized fuel in my bikes and stored them as I always do, but I did nothing from September until April to this battery. I’m very happy.

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.

So happy I got this. My 1150 GSA takes a lot of power to start and I’m really pleased and surprised with how light, small, and powerful this battery is. Worked better than any AGM or leas acid unit I’ve ever had

Been using it for 3 months without any problems in my 2006 Ducati Monster S2R 1000. Light and plenty of power to start the bike.

I went back and forth about buying this battery but I am glad I did end up getting it. So far it has been an absolute beast. Hold a very good charge. I did end up getting the remote restart adapter for it as I need to remove the entire gas tank to get to it.

My bike needed a battery. My husband is weirdly into reviewing and assessing all bike purchases pre order ( he has a lot of time on his hands and it is a long winter) this battery met his approval. We have no been left stranded. Battery is doing the job for which it is intended. Not leaving me stranded.

Shipped quickly.
