It took a while to get off our butts and get these up on the site for sale, but here they are! Why are we selling these now? Some things that come to mind:

  • They are very light. As in, about 2 lbs!
  • They hold a charge for a ridiculously long time. We let our FZ-09 sit for 9 months last winter/spring. Fired right up!
  • Made in the USA. Yes, American made lithium batteries!
For more details, see here: Antigravity YTZ10 Lithium Nanophosphate Battery | StoltecMoto

We'll be running a special for the rest of the month: pre-orders will be accepted between now and the end of the month. We're going to place one large initial stock purchase, so all orders will ship during early October. Members who pre-order will receive a 5% off coupon good for anything on our site. Yes - anything. With fall and winter coming up around the corner in the northern hemisphere, this would make a nice hibernation companion.

As always, let us know if you have any questions!

We had some questions that I figured I'd share:

Q: Can I use a regular battery charge?

The short answer: you'll need one of Antigravity's or Optimates. The longer answer can be found here: https://antigravitybatteries.com/faq/

But really, you won't need to charge the battery for up to a year of storage UNLESS there is a parasitic draw. As I alluded to above, we let our FZ-09 sit for 9 months one time (don't flame!), and it fired up without any issues whatsoever.


Q: Will you ship internationally?

Yes - anywhere but Russia.

For clarity, this is not the relocated, smaller sized battery used in the Stoltec FZ-09 that was located in the seat tray at one time?

We're running the deal on the OEM sized batteries. If you wanted the smaller battery, we could work out pricing for you. However, that installation required some specialized bracketry and a whole lot of patience.

I have been looking at battery replacements for some time- and this looks like a good deal. Just have some questions.

How long will it last if there IS parasitic drain- which includes a GPS tracker, heated grips and a alarm system? The stock battery keeps dying if I dont ride it for a day or two. I have to use a jump starter- and that's the second question- can you jump start these?
Other questions- Does more CCA mean it can provide more power? Say, for heated gear etc..? And does it face issues starting up in the winter like the other LiFe batteries (remember I ride even if it's <10 outside...)
Also, description says "Excellent for every day use in bikes up to 600cc"...does the FZ require a larger battery?

Well, the capacity on the YTZ10-8 is 9 Ah. So, it really depends on how much of a draw you have. Since that capacity is right about the same as the stock battery, I'm betting you'll get about the same life out of a charge. Without knowing specifics, I'd guess your alarm or GPS tracker is sucking up the juice. Might make sense to disconnect one for a few days and monitor the situation.

Regarding jump starting, you'll need to be careful. If you're using another motorcycle of similar charging output, you'll be fine since the battery won't know (or care) which electrical system is running. But, be wary of larger charging systems from the four wheeled variety (this goes for even the standard lead-acid agm batteries). That said, Antigravity makes a really slick jump starter. It's a bit on the pricey side, but it's got some pretty nice features. Given it's size and capability, it might be something up your alley. You could charge it in your apartment and keep it in a backpack for when you need it. See here: MICRO-START POWER SUPPLY JUMP-STARTER ? by ANTIGRAVITY

There's a few options there. I've handled them all myself and am impressed.

CCA refers to the 'cold cranking amps'. This reflects how well the battery will run the starter. The 'power' you're referring to is capacity - as measured in Ah.

Lithium batteries need a bit of a warm up when around freezing. Typically, turning the bike on and running the fuel pump (along with marker lights, turn signals, etc. will be enough draw to bring the battery to life within a few seconds. The colder it gets, the more time you give it. Turn on your heated grips while you suit up for a minute and you should be golden. Of course, YMMV.

I've used this same battery without issue on our FZ-09 and the same one is going into the FZ-10 this week. This battery actually has more cold cranking amps than the stock Yuasa (240 vs 190) and similar capacity (Yamaha specs 8.6 Ah, but all bikes I've seen have 9.1 Ah; the Antigravity YTZ10-8 is 9 Ah). We wouldn't sell something that would knowing cause an issue for you but like anything else...what you need and how you use it may be different. But like you, I generally ride my machines all year round. I'm good for about 20F-100F. We get more ice on our colder roads than you get in the city, but all that to say our use cases are fairly similar in that regard.

Useful info- we ride the same but not sure we have the same amount of demands off the battery!

As for jumpstarts, I was referring to the portable ones. I actually had the AntiGravity Microstart XP1 (I believe it was Made in China) which I bought last year. Just after the measly 1 year warranty ran out, so did the jumpstart where the battery randomly swelled and cracked the case open! (i had barely charge it 5 times & never overcharged). Seems like it's a common issue- AG would only give a new piece for 75% of cost. Instead, this time went with someone who gives 3 years warranty at more than half the cost. In the end they all seem the same with same issues. That experience made me a little wary of Antigravity though.

Anywho, I looked at this same battery too- but I hope someone who draws as much power as I do can shed light on how well it can withstand all that draw= need the alarm & tracker- esp after it has been stolen once already! Usually battery drain is not an issue if I ride every day and in the winters, the bike probably does not get ridden 7- 10 days max at a time. On a side note, can a larger capacity battery be actually fitted into the bike in the same space- just in case I decide to go that direction?

Yeah, I don't have any parasitic draws like you. Worst I do is run heated gear (jacket, pants, gloves). If you can't eliminate the parasitic draw and you're stuck with the culprit equipment, you might need to get savvy. I'm assuming a battery tender won't work for you and that you've already tried it. Barring that, maybe it's time to invest in a second standalone battery for these accessories. You can either leave it completely standalone and charge it if/when required, or you can work out a parallel circuit - with or without a relay/solenoid to keep the batteries separated until charging is required. A bit of a science experiment, but maybe it's worth it at this point...

I haven't lived with the Microstart for 3 years, so I won't comment on the durability. But initial performance was excellent and handled a customer/friend F350 awesomely. YMMV, of course.

As far as a larger capacity, yes. See here: YTZ10-12 | OEM SIZE 12-CELL LITHIUM BATTERY - Antigravity Batteries 50% more CCA, 33% more capacity. Same case dimensions...

I know this is an old thread, but I just wanted to bump it and attest to the quality of this battery!
I installed the AntiGravity battery roughly 3 years ago. Shortly after installing it, I hit a bit of a slump and didn't touch the 9r for over 2.5 years. No trickle charge, no starting the bike every month, etc.
Well, this past weekend I threw my leg over the bike and it fired right up!
What a great product; I highly recommend it.

Hi Stoltec Folks, Any chance of a post-Christmas / New Years deal on these? I'm closing in on the three-year mark on the stocker, and it's starting to struggle a bit. Either way, hope the holidays have been treating everyone well.
