Antigravity ATX12-HD. Heavy Duty Lithium Motorcycle and Powersport Battery with Built in Jump Starting, 8Ah, ATV, Quad, UTV, Scooter, Lawn Mower, Generator Battery - Harley, Honda, Kawasaki

Needed stronger battery for the Pan America and this is it. Arrived in the box with 13.4 volts present. This thing is lighter and more powerful than the stocker. Once you get a low voltage on the Pan America there are a bunch of false error code like 'check engine' the dreaded 'triangle' that only says something is wrong. Usually false but worrisome non the less. This solves those issues. Starts the bike much easier. holds it's charge much longer.

Works as described!Plenty of power!

It’s light, cranks well, and powers my accessories.

Extra cold cranking amps helps. Size was a little shorter. So you need to add spacers that were not provided to take up the extra space. Very light compared to lead acid battery was nice.

So, I forgot a device sucking power from the battery, and it shut off like it was supposed to. Then I put a charger on it and... wtf? It won't charge?!Oh yeah, have to push the button on top to allow it to charge.When it turns off, it turns off. There was enough power to start it after I pushed the button, but I decided to trickle charge it with my regular lithium-capable battery charger anyhow, because putting a hundred watts of juice into the thing like my alternator would have done would reduce its life.

Don't waste your money. Mine died after a 18 months and while they claim to offer a warranty - it's a pro-rated discount to buy another one. This is fine, except they make you send in your dead battery which costs an arm and a leg (up to $100) because it's a damaged lithium product (technically it's illegal to ship this via USPS).So at the end of the day, the warranty is pretty worthless and given the fact that it died on me within the products estimated lifespan, I give it a 1/5 stars and that's generous.

Used in an 09 Corolla. Was worried about overtemp causing issues but it worked on 90 degree days in stop and go traffic without any issues. Parked at the airport for a week and the car started right up without using the jump start feature. Had to buy screw in terminals and zip tie the battery down (I didn't like any of the small battery holders) but it's a great car replacement considering a fancy agm is about the same cost for my car.

I have now owned two of these batteries. I use them on my 1100 V Star. Holds a full charge for a year. Read that again. Noticeably increased cranking power. OEM size case fits in the batt compartment perfectly. The two things every biker has to babysit during idle months - carbs and battery. For the carbs I add Seafoam to the gas as a fuel stabilizer and detergent cleanser. For the battery I go with the Anti Gravity, and look ma! No trickle charger needed! They are expensive compared to conventional batteries, but I want the strongest, most reliable, no hassle battery available. This is it! My last one lasted for over five years, surviving 100 degree summer rides in SoCal, and etc.
