Antigravity ATX12 Lithium Motorcycle Battery with Built-in Jump Starting, 360 Cranking Amps, Replaces YTX12/YTX14, 12V Powersport Battery for Motorcycle, ATV, UTV, Scooter

I already have and had tested one of these on one of my other bikes, MT10, and now added this one to my 1290 super duke R because I was so happy with the other one. I wish I had started using these sooner. They fire up the bike faster, removing and installing is so much easier with the light weight and they really do hold a charge for months if you keep them inside unhooked like I do. My bikes are in a storage unit so no power or heat out there so I've got to pull my batteries every winter. Some of these newer bikes are really a pain to pull or install the batteries and these really make it a breeze. You also really don't need to charge them over the winter which is also nice. If they're kept in a warm house they barely lose any charge at all which means I'm not having to charge my batteries and monitor them over the horrible winter months I'm stuck inside. I make sure they're charged when I pull them out of the bikes and just sit them on a shelf and, boom, they start no problem when I put them back in. If you read about them they really hold a charge better and longer than a standard battery so these things really are a lot more worry free. If you're leav8ng them in your bike all winter then you've got to be more attentive but taking them out and bring them inside makes them incredibly easy to deal with.

My 2021 Iron 883 started giving me battery issues and it was time to change it. Originally my battery had 225 CCA. I decided to go with Antigravity and I must say, from the installation, the lightweight, and the CCA it is offering, the bike started up right away without any problems. Some reviews say the battery needs a charge or it doesn't work or whatever. Don't listen to the negative reviews. Honestly, this is my first Antigravity battery and I will continue using it for the rest of my life. Yes it is expensive, but wait until you see the difference. Would you rather pay for a different brand twice in a year or two that comes out to the same price as one Antigravity or would you like to pay for one Antigravity and have it last 3+ years. It even has a 4 year warranty on it on top of that. I would recommend this one to EVERYONE!

Expensive but works good. Piece of mind being alone.

I haven’t been able to ride my bike as much as I would like and the old liquid battery gave up on me after sitting in the garage( on a tender) over the winter. I finally bit the bullet and ordered the antigravity battery. When it arrived I thought it was a mistake because the box was so lite. I installed the battery and the bike started right up with now issues. The battery also has a jumpstart feature which is nice to have but hopefully I won’t need. If you get and intend to keep it on a tender it does require a special lithium ion tender. If you put it on an age tender it will destroy the battery or the tender or both.

Seeing how Shorai kept increasing their capacity for what is the right size for a LiFePO4 i was worried the recommendation for Anti Gravity restart batteries might be regrettable as it's the original 12Ah (equivalent). It's a perfect fit (no shimming needed as with other 12Ah equivalent LiFePO4) and starts bike flawlessly. I'll update when i have used it in winter too, as that's when LiFePO4 really struggle and i needed a new battery now, in summer. Since the restart button isn't reachable on my bike without removing a lot of fairing i added the $20 remote with SAE connector, which wakes up the BMS if it shut down the battery to preserve the last capacity to get you started, if the remote is more than a case for a 9V block with a switch I'll be surprised, but i have it on me, hopefully never need it. Now i just need an appropriate charger as i don't want my constant current bench supply in the garage for that (works great though due to the raising internal resistance lowering the charge current after the battery is full)

Left auxiliary lights on by mistake, went to start bike and it was completely dead. Pressed the jump start button and bike started - very nice feature

The battery is definitely super-light. It comes with the hardware needed for the install, and has a pretty smart arrangement of the terminals for different situations. It went right into my Indian FTR 1200’s battery tray and OMG what a pleasure it was to install it compared to the couple of times I wrestled the old LA battery into place after charging it. After install, the FTR fired right up with authority. I can’t speak to static or dynamic longevity because I literally just put the battery in a couple of weeks ago. Time will tell, but I suspect it will be fine. And even recharges will be more pleasant due to how light the unit is. I just wish these guys were a little less expensive.

Had this installed on my Indian Scout Bobber. It worked great for cold weather starts (cold as in ~50º F) compared to the stock battery. But it did not last through the winter. I went to start it recently and my bike would not even turn on and prime. Took the seat off to get to the 'refresh button' and the bike turned on, but would not start. It tried to turn over but only made half chugs, and now will not turn on anymore. It's been on a trickle charger for about a week and the bike still will not turn on/prime. I expected better. Now I will have to look elsewhere.

A good quality lead acid battery is well over a hundred bucks, will last on average two seasons in my KLR. I decided I needed a change on this whole battery nonsense - went lithium. Wow, what a difference, fires right up after sitting unattended in the bike for the whole winter - amazing. Another summer almost past and this battery has been outstanding. Big bucks, sure, but worth every penny if you are a serious rider turning lots of miles with any amount of electronics on board. Oh, the double terminal setup on these batteries is brilliant. Ride safe.
