I have the 18ah also. Im in north central Indiana and am experiencing the same things gary is talking about. I went out to the garage yesterday to start the fjr and it wouldnt start till I woke the battery up. But it did start. The garage temp was 28 degrees. As far as price- I paid 169 bucks for it and thats what the dealer wanted for a OEM battery.
Yeah, but an OEM battery will start your bike without the shenanigans. AND...If you shopped harder, you could have found an OEM or close for around $100...
yah I know. My luck with batteries has been **** so I was searching for a better mouse trap and was willing to take a chance on it. I hear some you talk about batteries lasting 5 years or so but I have NEVER gotten more than two years out of one.
LAF, two years is not normal.... I suspect you may be letting the bike sit too long allowing the battery to discharge below half charge (approx. 12.3V). Lead acid batteries will deteriorate if that's done too many times. So, the cure is, if it's going to sit a couple of weeks, put a Battery Tender type charger on it.... I still have the original battery in my '07, and while it hasn't had a perfect life, I have tried to keep the 50% discharges to a minimum. I know guys that store their bikes for the winter and don't put a charger on and claim long life.... hard to believe.

Zilla, agree, all those starting attempts at low voltages can't be good for any high draw motor of any kind. There's no compelling reason to buy this expensive thing, lead acid batteries will last 5 years if treated right. The lithiums probably need to grow in size and capacity to be ready for prime time in a bike. That might get even more expensive............

Well ain't that just the *****! That's exactly what zilla's wife says about his pecker..

Glad to see you are back to normal again.

In this case it's not the size that matters, it's the chemistry. The battery is giving the cold shoulder and not putting out. You need to push the right buttons and warm up the chemistry before it will start to spin your crank.

Keep it up *******. Keep it up.

 
Not to blast anyone but this is a battery. It has one function, to fire the bike. Way too much drama over a very expensive battery. When they get the tech caught up to the enviorment I will be interested, till then it is not ready for prime time in my part of PA.
No blast received... But I think all the drama is evidence that the forum is working as it should. I've seen that as I suspected, a number of guys (many of which may well NOT have posted anything on this thread) were thinking about this battery.

On another note I found it interesting that a couple of guys were able to start their FJRs in temperatures WELL below the point where mine will not (on the first attempt).

You probably got a bad one out of stock, dude.....

Me, too.

If I hadn't of had pretty much the exact same 'sperience, I'd consider that as well.

Maybe I'll bring mine to Tech Day VI and we can do whatever with it.

 
so thanks to no money for tires and brakes, the FJR's been sitting for almost two months now. Nighttime temps getting into the low 30's most of the time.

So being stupid I failed to pull the Shorai because I didn't expect to be not riding this long. Went to start the bike, and the battery is completely flat-not enough to even twitch the dials.

I'm assuming these batteries cannot be saved once they've been completely discharged. FML.

I am pretty sure that's what they say on their website somewhere. But they are supposed to hold charge for a long time. Longer than 2 months. Longer than a conventional battery which will hold charge longer than two months in cold temps. I would call them.

 
....and definately let us know what they say as a very large number of us just can't get any sleep over this. I'm still having nightmares about purple oil...

 
it might have held a charge if there wasn't the cold temps and a constant drain from the bike's electrical system. There is no outlet in the parking lot so I couldn't use a maintainer. It might have held had I been smart and disconnected a lead.

Perhaps. But the FJR's doesn't have too much parasitic drain. I still think it should have been ok after two months.

even the Yuasa or BikeMaster wouldn't start if left for a week under similar temperatures without being started. much less two months. The Bikemaster that lasted a whole two and a half seasons needed a jump start if left unridden for more than 4 days if temps were in the 30's.

Then there is something wrong with your FJR. Cold is a GOOD THING for battery storage. Just not for battery performance. A typical battery should start the FJR fine after a week sitting in those temps.

 
Yeah...Unfortunately Greg is right. Sadly, mine has sat for a month and started right up, on the OEM Yausa battery. If yours is killing batteries in a week, something's up.
