    If more is available, and it fits, and the price premium is negligible(IMO), why not? I mean, we all bought 990's when a KLR250 would probably work just fine, right? :evil

    I'm looking forward to the day when I wheel up to someone in a parking lot and help them jumpstart their car...LOL

    Hi Mooky, I'm down in sunny Whitstable!

    also guys with reference to the other replies querying the choice of 18Ah battery as against 14Ah..... I chose 18Ah. Once you've been on a rally and had to bump start the 950 I suspect you might too.......:norton

    Hi,

    Thought I would just check with Shorai on suitability of my existing charger. very helpful response see below

    Hi Ian,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>
    <o:p> </o:p>
    Their documentation indicates that the charger should be fine for LFX, as the DESULFATE mode is based on sensing a high battery resistance. Since Shorai LFX ALWAYS have considerably lower resistance than even a brand-new lead-acid battery, the desulfate mode should never “kick in”. The only possible exception I can think of would be extreme cold, if the charger does not compensate for temps. I therefore recommend that it be used only when ambient is 32f (0 C) or higher.

    In order for the recovery mode to engage, the OptiMate circuit needs to "see" a high resistance across the battery<o:p></o:p>

    terminals. In the case where the battery remains connected to the vehicle's wiring system, any battery-supported<o:p></o:p>
    accessories will automatically lower the overall resistance (battery plus accessories) that the OptiMate is going to<o:p></o:p>
    "read" when it tries to pass the limited maximum 200 mA to the battery. Therefore the OptiMate will not read the<o:p></o:p>
    battery resistance as being high enough to indicate deep discharge / sulphation and therefore will not engage the<o:p></o:p>
    recovery mode.

    However, if you ride even once a month, you should never need to charge the LFX. We are NOT lead-acid, do not sulfate, have slow self-discharge, and do not need to be constantly fully charged!!

    Thought I would highlight one of Shorai's responses, which seems to be holding true so far.

    With the help of inmate Head2Wind (Ken) with Adventure Machines, http://www.advmachines.com/ I got a LFX 18A1-BS12 on the way for my 2006 ST1300a.

    Please contact him if you need help ordering one, he was the bestest in working out my issues :deal :D

    Thanks Ken

    I received my Shorai today. I ended up settling on the 18amp battery and will install it in the morning. When I opened the box it had a Wolfman duffel in it also. :evil Thanks CJ

    I saw a pic of a Batter Tender on the first post, but I can't tell if it's the "normal" lead-acid one, or a different one.

    Can a Shorai be charged with a normal Tender? I just bought a 2-port Tender, and I have no desire to replace it, featherlight battery or no.

    Yes, Shorai Tech verified the plain old (lead/acid) standard Battery Tender (Deltran) including the Junior, are just fine. Nothing special needed for the lithium cells. Just do not want a "desulphate" mode. You can go back to the first post and look at the pix. Those were my Battery Tenders and are 'standard' ones. You can also email Shorai with your specific battery tender and ask. They are good about getting back to you.

    I'm aware of those pix, as I mentioned-- they didn't provide the information I needed but you did. Thank you.

    It's nice to have a contingency plan in place in case this winter is the stock battery's last.

    I would worry less about the vibration and bouncing with the lighter battery, if you have it packed correctly in the box. If you let it bounce inside the box, then you will probably induce premature failure.

    Just ordered one from ADVMachines. My OEM from June of 2003 is still doing the job, butt 8 years is too much to ask from any battery. Think I'll retire it to my museum of Over Extended Parts (along with my OEM LC8 water pump, fuel pump, and front rim, to name a few). This Shorai is so light you could carry a spare in the luggage for those long trips, if so inclined. Thanks for the writeup cyborg. Great addition to the HOW.

    Great Post,

    If any of you who are running the Shorai batteries actually deplete the charge in one and have to charge it, please let us know how it responds to your charger. Same for just a preventative trickle charge. AGMs, Gels and LI batteries all respond differently to a charging cycle and have differing "Ideal" charging rates. The problem is that our motorcycle's internal charging circuit as well as the conventional trickle chargers most of us have are optimized for lead acid charging rates. This is why some earlier versions of so called "Super Batteries" end up with much shorter than expected life spans. I'm not saying that is the case here, I'm actually interested enough to want to know the outcome. I'm just saying it may be the only potential down side. :norton

    Just installed one on my 950 adv s and it is nice and strong. Super easy install and so nice of them to include the sticky foam to make it that way.:thumb

    Put one in my GasGas 400 (notorious for killing any battery)... at 25 degrees yesterday morning it would not start my bike.

    The Gassers are fuel injected which requires to have a pretty good battery to kick in the fuel pump, etc. No go.. Ended up pushing it up a hill and push starting it. Within a minute the battery was fully charged and i could stop and start it at will..

    I wouldnt say it's bad, especially with the 950's bigger battery, i think the gasser has the 14a.. may try to switch it out and see if i can get the 950 battery in the gasser battery box.

    At any rate.. i've killed one.. :cry ... but just for a minute.. :clap

    Mark, I've ridden my v-twin Aprilia RXV550 to work a few days this week to keep it limbered up. It's FI as well and can be a bear to start old 27F mornings. As expected, the first crank attempt, no go -- but I know the first cranking warms up the battery. I waited 15 sec or so for the heat to seep through the battery a bit then the next crank runs were full force and it lit right off. :thumb I have the Shorai small case 14ah in that, the only size that will fit in it's battery box.

    Below freezing, these lithium batteries need a warm up pull on the amps.

    yeah, i've watching the thread and realized the shortcomings due to weather. So did try to wait it out, tried 4 or 5 times over about a 10 mins period before I pushed it up the hill.. Still in love with the battery.. as any other battery on this bike kills it right away regardless of the temperature out.. oh and this battery has never been on a charger and it's been in the bike for about a month, used about 2 times a week at Walker.

    Would plugging it in to a battery tender first warm it up enough to wake it up?
