I decided to step up to the highly regarded Lithium battery. Actually, I bought two at the same time, one for a Honda CRF 450 X and A Yamaha TTR 125LE. The 450 may be near the max for this battery, the TTR 125 consumes all but nothing. There is zero load when the bike is not running. I ride the bikes about every other week, sometimes more , sometimes less. These were bought and being run from May until mid July, in the Pacific Northwest. Real moderate temperatures, 70-80 degrees Fahrenheit. Just about ideal for any battery. In mid July, after the free return date, these things left both bikes completely dead. The CRF 450X, maybe understandable in that it takes more to crank. The TTR 125 has less than 10 hours from the factory, started and ran like a top with the factory battery. Pull the choke, kick once and she fires. These batteries simply will not hold a charge as advertised, and are way too expensive to be discarded every two months when they turn into garbage.
If you buy this product, buy several spares because you will need them. Hopefully you have way more money then common sense, and a bucket full of patience, because these will flatten your wallet and test your determination.
When you pay for this trash, then realize that you got hosed, know that you had fair warning.
For the money, if there was a way to enter a "Zero" star, or a flaming "I hate This Crap" star, I would send it.
So at this point, I have several hundred dollars wasted on what looked to be a good product. If they take these back and make things right, I will update my post. Until, and if then, stay away like the plague from antigravity ATZ-7-RS Lithium RE-START batteris.
I own seven motorcycles of different types. I’ve used Lipo batteries for years with mixed luck. I’ve purchased three antigravity batteries. Of which I now have none! All toast, after a year or two.
Three weeks ago, January 3, 2020 I Purchased an anti-gravity AG-ATZ-7 for a bike I am building for a long adventure ride. The battery has been in the bike on a stand in my garage for a couple weeks. It has Ben used to start the bike about half a dozen times. One night the key was accidentally left on. I didn’t catch it because the headlight was sitting in my workbench. the battery drained and that was the end of it . It is now dead and worthless. The jump start feature worked a couple time but it will not working on its own. Tried re-charging with a Lipo charger. It shows 13 V on my multimeter now but will not start the bike (wr450). I can start the bike with a portable battery pack and it starts with an alternate battery. But not the anti. Gravity.
So, if you’re thinking about buying one of these batteries keep in mind that if, for any reason, the battery is drained below 10v, it will end up in the trash. Read their warranty. You are SOL. Completely ridiculous and absolutely not worth the weight saving or cost of this battery. The unreliability and risk of losing your battery while on the road, is simply not worth it. And they provide no help. I am done with this brand.
This battery sucks in the cold. I live in Southern California it does not even get that cold here. Yet I have trouble starting my motorcycle in 50 degree weather. Have to crank my bike three times for a good while before it will start. I guess the only plus is that it has yet to leave me stranded
Update- well guess I was wrong another 50 degree night and got off work and my motorcycle would not start tried 3 times and battery would not start my bike so tried the reset button anddddd nope still did not start my bike. Had to use my buddies jump box to start my motorcycle. I would stay away from buying this battery
Seems to be holding up nicely. Definitely reacts only a tad less powerful in colder weather, it seems. I live in the SF Bay Area so freezing isn't really common, but I live in a warm area and then work in SF. I leave late at night at about midnight and the bike works well. but turns over just a bit more sluggish at night. I can't rate on longevity yet, though it is holding its ground. I'm hoping for a good lifespan from this battery!
Very light compared to the AGM battery that I took off the bike. Hoping not to have to use the restart feature but nice to know its there just in case.... Weighs about half that of the previous battery and having the extra battery terminals is a great idea to allow for different mounting options depending on the sides the +ve and -ve terminals are on on your vehicle. You do need a specific Lithium battery charger though - but it holds charge perfectly.

Description
The NEW Antigravity ATZ-7-RS is a hi-power lightweight Lithium-Ion battery, built with our groundbreaking RESTART Technology (built-in jump-starting) so you won’t ever get stranded with a dead battery again! Directly replaces the OEM YTZ7S, YTZ5 and others. 90% of off-road bikes use this size as well as some street bikes.
This thing was a work of wonder for all of 3 months? Fired my bike up 3 weeks ago and it started right up, ran fine for 3 minutes, then it shut down and the battery was COMPLETELY DEAD.
I ONLY HAD A HANDFUL OF HOURS ON IT.
Meanwhile my wife's OEM 5yr old crappy Honda battery still running strong.
Direct fit for my 350 EXC-F. Much better cranking power than stock. Weighs about 1/3to 1/4 of the stock. Haven't gotten to use the restart function or try out the long term reliability, but will update if I have any issues
Installed this batter in my Honda CRF250L Rally (2019) to replace the stock battery. This batter is significantly lighter than the lead-acid battery. This battery is much smaller, and you will need something to help provide support for the battery. The spacers that came with the ATZ-7-RS were not enough.
Roughly half the weight of the battery it replaced. 2 places to mount wires on each of the 4 terminals! (Tops and sides). The re-start feature is the cherry on top! It takes away all anxieties of depleting power from letting my bike sit for long periods of time. Older batteries now seem dumb. I love my new smart battery. I highly recommend!
I don't know if I got a dud or what... Recieved this, super excited to put it in my ninja 250. Only to find it completely depleted upon arrival. The charger won't even recognize the battery. Did you guys just send me a 170 dollar paperweight?
