Anti-Gravity AG-ATZ-10-RS LITHIUM-ION Battery

After being so impressed with another Antigravity battery on a different bike, I knew exactly where to turn when my other motorcycle needed a new one. I went with the ATZ-10, and it has completely lived up to the high expectations set by the brand. It’s another fantastic product that delivers on every promise. Installation and Form Factor: Just like other batteries from Antigravity, the first thing that hits you is how unbelievably light this thing is. You're easily shedding 5+ pounds off the top of your bike, and you can feel it. The ATZ-10 is a replacement for the stock YTZ10S and is slightly smaller than the OEM case size, but it comes with adhesive-backed foam to ensure a perfect, snug fit in the battery box. The four-terminal design is also brilliant, giving you flexibility and making the connections simple and clean. Performance and Key Features: The cranking power is just immense. The bike fires up instantly with a speed and authority the old lead-acid battery never had. But the real reason you buy an Antigravity battery is for the RE-START technology. The peace of mind knowing the battery has its own built-in jump starter is invaluable. I had an instance where I accidentally left my accessories on, and instead of being stranded, I just pressed the RE-START button on the battery, and the bike fired right up. It’s a feature that you hope you never need, but you'll be incredibly thankful for it when you do. Conclusion: Antigravity has proven itself to me once again. The ATZ-10 is a top-tier battery that provides a noticeable performance upgrade through weight savings and massive cranking power. The RE-START feature is a true innovation that every motorcycle battery should have. It's a premium product, but the quality, performance, and built-in safety net make it an essential upgrade for any serious rider.

My son purchased this battery for his bike when the factory original gave out. I recommended it as it is significantly small and lighter but with increased cranking amperage. I purchased one myself to put in my Triumph Daytona 675 and have had great service from it! Both bikes start easier and turn over quicker with the battery and the reduced size makes them easier to install and lighter is always better on a motorcycle. Included foam shims allow you to shim up the battery in the battery box so it won't wander around when riding. I have had the battery in my Triumph for going on 2 years and have never even had to use the build in jump start feature! Excellent battery! A bit more expensive than a regular battery but the increased power and lighter weight are worth every penny!! I would recommend a battery maintainer/charger to get the most life out of the battery. One that is recommended for lithium batteries.

Motorcyle: 2018 Kawasaki Z650 I'll start by saying I am no mechanic, but that doesn't stop me from trying to do the work myself. My old battery started to drain regularly, prompting the replacement need. This battery came with easy instructions and easy mounting options with positive and negative terminals on two corners each. The battery weighs just about nothing, feeling almost fake with how light it was compared to the original battery. The only annoyance of the installation was the small space to work, though this is likely related to my not being familiar with the practice. Starting the motorcycle had never felt quite so good, with it turning over almost instantly. I also felt the throttle became more responsive with the new battery, feeling more responsive. I have not had to use the auto-jump feature of the battery, but having the option to auto-jump the battery feels very reassuring, especially with so many accessories that can drain the battery without you knowing.

Awesome features and dependable. Love the reset button.

I've owned many brands of power sport and motorcycle batteries. This battery and brand is THE worst I have ever bought. Complete waste of money, equal to just throwing it away. They are overpriced at that, probably due to their advertised functions that don't even work, on top of the battery being terrible quality. Failed in well under a year. Restart function is a total gimmick and never once worked. Supposedly if it fails in under a year they will replace it. Mine did in far less than a year, but unfortunately due to how busy I am I didn't place my warranty claim until almost the 13 month mark. I went to the website, downloaded the claim form, filled it out, and submitted it to the stated email address and included my proof of purchase. Followed everything to a T. Never heard back for over a week so I sent a follow up email. Waited about another week and still no reply. So I tried calling the warranty department. Could only get a voicemail so I left a detailed voicemail stating the above. Waited several days and no call back. So I gave another call and still, right to voicemail. It's as if I'm actually being purposely avoided, like the calls are being dodged. To this day I have never gotten a response. So I went ahead and bought a NoCo brand battery and WOW, the design is MUCH better, everything about it seems higher quality and the terminals are exceptionally well designed, MUCH better than this brand, and MUCH higher quality. The NoCo battery is much more reliable and works much better overall. I'd recommend NoCo or at least ANY other brand than Antigravity who sells gimmick functions purely for show, are total garbage, and who refuse to honor their warranty.
