Sorry about the Jeffo reference, that may be a sore spot with some.

ROFL, no worries Kruz, I don't have a serious bone in my body. Site needs more humour. Bring it.

I think you'll get a new one and be on your way. See if you can get them to anny up the freight charges.

Hope so and will ask. Sent them this link. It would be nice to see them make a Post.

From reading the above, starting to sound like buying their charger with the battery is almost a Must. I for one had no intentions of ever charging it. Kinda makes the price a bit Chunky to own one ?

Sounds like they have great customer service which is Awesome and Rare. Also sounds like the shorai company at the present time is not using their get out of jail free cards which they do have them written in under warranty. I will admit I knew none of what they did not cover. Maybe I should read more ? Naaaaa, I would have bought it anyway lol.

Fingers crossed.

my bike sat for this past week, went out to start it up today and it was dead no dash lights or nothing. they say the first batch of these batteries are having issues the chips in them that keep them from overcharging are frying in them. long story short they are overnighting me a new battery from the second batch

---

Wow, are they all doing this, I mean the first batch? I was first to jump on the bandwagon, hope mine doesn't take a dump. So far so good though, no issues yet, fingers crossed!

I have the same charger you do I believe and I won't use it on the Shorai, my manual says something about a de-sulfate mode.

From some of our earlier conversations, I think yours is not the same as mine. I bought mine in 08. Then I bought one for my father in 2009. It was the basic maintainer Schumacher makes but the later one was a bit different--updated somehow. Seemed a bit nicer, actually.

Mine says MODELS 1562A on owners manual. Nothing about de-sulphide that I can find. You would think that would be printed right on the box. I think I'm going to be okay on this but better believe i won't be hooking back onto a charger unless it is a Shorai charger.

Wow Scott. I'll bet there is allot more that don't get reported.

long story short they are overnighting me a new battery from the second batch

18AH or the 14 ? I was waiting for a reply from them yesterday,,,,,,, Still waiting. I will Call Now. Is that what you did ?

romans it was the 18a yes i called them to impatient for email lol, but Shorai doesn't have any in stock right now, sept 26th was the expected date they gave me to get some in. super bike supply is who sent me the replacement kudos to them for doing this shows great customer service on their part

kruz it the 18a batteries i believe

rook yesterday was the first time id ever put a charger on it. that is not whats making these fail its something inside the battery itself a chip is going bad that keeps it from charging a tells the batt to discharge itself from what i got out of it. I'm not dissin the batt here i think its great jus got a bad 1 and they are taking care of it.

rook this is from their web site

Q. Can I use Lead-Acid battery chargers or charger/tenders?
A.Yes. HOWEVER, you may NOT use a charger/tender if it has an automatic "desulfation mode", which cannot be turned off. We have confirmed with Deltran, makers of the "Battery Tender" brand, that their products do NOT have a desulfation mode, and are therefore OK for use with Shorai LFX, for example. But the best possible charger/tender for Shorai LFX is the SHO-BMS01, which will be released on about March 15th 2011, we expect. It uses the 5-pin BMS port in the LFX batteries, in order to monitor, diagnose, and balance the individual cells during charge. And it also has an optimized storage mode that will give the longest possible service life to your LFX.

If you are storing your vehicle and want to check the remaining capacity, or you're a racer with a constant-loss system, you'll want to know how resting voltage (i.e. with no load or load under 200mA) maps to remaining capacity. LFX batteries should be maintained such that 20% capacity remains at minimum, as best practice. Use a good-quality voltmeter to check remaining capacity, and consider recharge whenever the battery capacity falls to about 50% remaining. Of course, if you get the Shorai dedicated BMS01 charger, you can just hit the "Store Mode" button and leave it to do the work for you.

so battery tender is A ok for this

kruz it the 18a batteries i believe

I'm going to contact Shorai and find out, I think Garth had either a 12 or 14 AH and his bit the dust so now I'm curious. I don't want to get stranded out in the middle of nowhere with a dead battery.

Thank God it wasn't a Jeffo map!

I think it was a Jeffo map, didn't Roman report seeing 3 foot flames coming out of his battery box....?

WHEEEEE!!!!!I want one!3 foot flames...AWESOME BABY!Can you imagine...3 foot flames rippin outta yer pipes comin around that sweet dark curve....WooHooooo!

[/quote]..could ask for a 14 amp. I bet those are in stock. Easy to install. just a piece of plywood and a couple zip ties.

a chip is going bad that keeps it from charging a tells the batt to discharge itself from what i got out of it. I'm not dissin the batt here i think its great jus got a bad 1 and they are taking care of it.

I agree, R. I was a little skeptical from the start. The thread we have here has extensive posts by the Rookster himself digging through the internet rumors and heresay and upstart company promotional material......... I never like to be first on this kind of thing. always go with what has been established to work since that info is right there in front of you on the web along with the potential (and proven) snake oil products. I'm not too surprised we are hearing about a longevity issue. That is always the thing that cannot be tested except by time. I will be minimally satisfied with 1 year service for what I spent on the battery. As long as Shorai is willing to make sure we have batteries that last more than 1 year, I would say they are proving themself as a reputable co and deserve repeat business. If this one dies on me this time next year, I'd happily buy another. My stocker lasted 3 years but it is 5x heavier.

Rook, I was really hoping the claims of lasting 4 times longer than a lead acid battery were at least half true,,,, Maybe asking to much ?????

Roman report seeing 3 foot flames coming out of his battery box....?

ROFL, No wasn't me, but I would have been more than happy to trade a 4 foot jeffo flame for a quater inch spark-e the day I was pushing my baby home. I'm sure the toe truck option would been one hell of a heart breaker.

Just thinking, maybe waiting for a new batch is a good thing. New onesmay have the bugs worked out ?

Rook how big is that tiny batt of yours. Maybe we could carry a spare in place of the tool kit ?

Rook, I was really hoping the claims of lasting 4 times longer than a lead acid battery were at least half true,,,, Maybe asking to much ?????

.......that be 12 years. That seems like an awfully long lasting battery. Be nice if they get it ironed out o where that becomes a reality. Time is the only true test of time. They can do accelerated tests but that does not always coincide with reality. Tough to simulate a decade in a few days or weeks. Too many outside variables in a decade of time.

LOL......are you serious????????? hahahaha, yeah, I think there is a recess in the seat bottom over the tool kit . It might actually be possible.

4 3/8" wide x 3 3/4" high x 2 1/4" deep

looks like you might actually fit a couple under there if you want.

Romes, what's your ride profile typically? 100 miles, 200 miles? That could be the difference, I have more months in service and probably more start cycles than most on my Shorai but I do short intense rides on the CBR. Maybe I'm not giving the battery a chance to overcharge and cook? Remember, it has to recover the energy it lost during the start. I'll have to get with the Shorai technical department and see if there is a way to test the chip for proper operation or is it just a ticking time bomb? If they're all failing from the early batch, what do I do? My last tow was $125 and that was only 7 miles. If I'm out in the boondocks a tow could run several hundreds of dollars easily. Just food for thought.

Lead/acids are heavy and old tech but they have one advantage, when they fail they almost always give some advance notice. If you get caught out with a dead L/A you proabably ignored the warning signs. These new LiFe polys sound like they just quit working right out of the blue, kinda like the old NiCad packs did. this is something none of us took into account, I fingered the technology had been around for some time and was thoroughly tested before selling to the public. Not ready to give up yet though, the weight savings and fast cranking are too important to ignore.

Just sent to Shorai Tech Department

Shorai Contact Request
Hello, I am a Shorai battery owner and have had mine in my '07 CBR 1000RR since January of this year. So far I love the battery, cranks way quicker than the standard L/A and is superlight. I am a fan.

I write to you however because of talk of several Shorai failure rumors that are circulating around the various on-line motorcycle forums. The rumors are that some of the early release batteries have a defective chip within that prevents overcharge. When these fail the battery can experience sudden failure. I know one owner personally and he was left stranded when his five month old Shorai quit.

Should I be concerned as I have one of the first Shorais over here, now 9 months old and I am concerned about being left stranded with a dead battery. Is there any way to tell if my battery is affected and how can I test this chip?

Thanks and best regards!

Exactly. Not to mention toe trucks don't always have proper tie down straps.......ugh Hard to watch.

This was the reason I was asking rook about his weee little batt. If the bike dies on the road wife could put a 1 lb batt in her purse and bring it to me lol. Alan key 10 mm all taped together. Sounds corney but as you mentioned A toe can get Chunky on the wallet. Least this way I'm back in the Game.

Or these batteries get taken out when doing a long haul. Peace of mind.

Did you guys read under waranty if you leave lights on and batt dies or volt is run to low it is done,,,, Something like that. Heaven forbid you stop with kill switch and forget lights on...... New batt please. Did I read it wrong ?

Well Romes, I am going to definitely hold off on buying anymore Shorais until we get this all sorted out. I can deal with overweight, finicky Lead/Acids cause I understand 'em and they rarely leave you stranded unless you just 'aint paying attention. Hopefully this is just a minor bump in the road, I really want these batteries to work out and live up to their potential.

ok guys heres the scoop, I talked to the Shorai sales manager today(he called me)the story goes like this:

their first tier supplier was not able to supply the parts earlier this yr due to the tsunami in Japan forcing them to go to a secondary supplier for the parts in which they are finding out now that they were not up to par with the preferred suppliers parts. According to him this is not a widespread problem and they have got it corrected.

FYI: the 18a1 is the recommended size for the zx14 now. the 14a will work but may not last as long as the 18a and the charts on Shorai website now only show the 18a as the batt for the zx14

hmmm, both you and I have 18AH and we are not doing so well.

rook heres the scoop on the chargers(from Shorai sales manager) battery tender brand is ok but their chargers are specifically designed for their batteries they drop the batteries charge down to 50% (when charger is in STORAGE mode)and keeps it at the desired 50% storage mode level. its a 5 pin plug (pigtail that stays in the battery) sounds pretty cool and I'm planning on getting 1 b4 winter hits.

---

romans lol i hear ya and i waited till just 2 months ago to get 1 of these. they did tell me these are starter batteries not deep cycling so if lights are left on to long(how long is too long i don't know) the battery will eventually flat line. I'm guessing that means die lol.

not good news for me with 400 led's running at bike nights lol.
