Antigravity ATX20 Performance Lithium Motorcycle Powersport Battery - Built-In Jump Starting, 10Ah, UTV, Jet Ski, Generator, Victory, Harley, Indian

This battery is great. Fits perfect and works better than expected. Very pleased, would definitely recommend this to others needing a strong battery. The 4 posts is more helpful than I thought I ended up rerouting some wires which as a bonus cleaned up my whole under seat wiring and fuse block. And the restart feature hopefully won't be needed but glad to have it if I do. Great for my peace of mind when I go out on the road to the mountains or some place aways away.

Works great in my 2014 Victory CCT. Whips engine over fast and all accessories functioning normally. I'm still amazed how light it is compared to the original battery I replaced. Worth the investment.

These anti gravity batteries are the most convenient battery you can purchase for your motorcycle. They never need to be hooked up to a battery tender, they are always ready to start up your bike with no hassles whatsoever! They are super light and maintenance free! These batteries make lead acid look like a model T compared to a Bugatti! You won’t be disappointed! Just remember that these batteries are Lithium! You will definitely have to upgrade your rectifier to support a lithium battery. If your bike had a lead acid battery then your rectifier must be changed otherwise the anti gravity will not charge properly and will eventually be ruined. It’s worth the upgrade! Lithium batteries like a nice steady charge. Lead acid likes a fast charge. This is all regulated by the rectifier. So upgrade the rectifier with a Ricks Motorsports lithium rectifier and you will be good to go! Always! No more dead batteries!!!

Initial purchase was good. After a month of delays, waiting on other parts, I installed this battery. It turned out to be a bad battery. Internal failure according to the testing equipment. Neither Syko Helmets, nor Antigravity, would stand behind their product. Antigravity Battery company used the excuse that Syko Helmets were an unauthorized resaler. Syko Helmets denied this and insisted that I argue that with Antigravity Battery company. Then Amazon would not help either. Amazon said the request was “out of the window of return.”I lost. The companies all made money and I got nothing.CROOKSThe antigravity battery is a good product. The product is sod by a GREAT Seller. A good price, quick response after the sell to get product shipped at a fair price and….. the product was delivered weeks ahead of the estimated date of delivery. Thanks Syko Helmets.

I have a s&s high compression 113 displacement motor on my custom bike it eats lead acid battery’s won’t start after one weeks use. Not enough cranking amps arc 20 680 cranking amp does great never has failed never needs maintained best $319.00 I have spent

The weight is unbelievable! It’s so lite. I was going to put pressure reliefs on it till I seen this. They say to charge it first but it spun my bike over and over and started so quick. Whole lot cheaper than head work !!! Thank you

I bought this for my 1986 Harley Heritage Softail. The engine has had a little work done to it (compression > 140 psi) and it was hard for the existing battery (a brand new glass matt type) to turn the engine over. The antigravity spins the engine over really fast. The battery is expensive and well worth it!

first thing is the thing is so light i can't believe it could start anything. i installed it in my problem bike that has trouble starting on a 400 ccv battery with compression releases. skeptical i hit the starter and instantly it cranks faster than ever with out delay. i did it 3 times to be sure i was not dreaming. then i realized i had not pushed the compression releases in. with them in it spun ridiculously fast. after all that the battery terminals were not even hot. i have burned off several on this bike. i am sold. now to see how it holds up over time wrapped in a oil tank in the florida summer. regardless the cranking speed is awesome

lasted 2 months , left me stranded in the middle of no where
