Tried the top of the line LI battery, fails when they get cold as they have NO Cold Cranking Amps. When warm they work but get them cold and they do not work. At least for my application the only battery is a Yuasa Z7S.

They don't even rate LI batteries for cold cranking(cold battery scenario) because they cannot even preform the test as they preform so poorly. FYI
Thanks from jon andersson

@Blutor; How you wear your starter grip clutch out!
Lithium Ion I use on the summer track bike, nothing youd use during winter, unless you like changing the starter freewheel/grip clutch, plenty experience here. Keep pounding the bike like that is expensive, and certainly NOT recommended, if it dont fire the first 3-4 strokes something isnt right.
To keep the flange in mint condition you need to stick it max current right away, as much as soon you can. Proper speaker cables or equivilant will help too.

However turning the bike over with any battery and then wait 30 seconds is ALWAYS a good idea below 10 degrees C, as with the low temp of engine components fuel evaporation will be slow, either do that or just put a cc of fuel directly into the throttle body -> instant start with the bonus of no additional wear on the starter, quite convenient with how easy it is to rip the seat off the 570 and then just a prepared syringe with fuel to shot it.

How we do it on the ice when its darn cold, like -20C No hokus pokus, no money, just hillbilly knowledge, well you need to bang a sister with a syringe, that may cost you..

Edit: Whovalley Sweden and not knowing this, just spjewed my beer You cant be from there or 'here' in general?
Thanks from bushmechanic and tourist

If I ride during winter I always start from my garage so the is no problem with a cold engine. mc in the winter. But now I'm thinking of riding with a timbersled kit.
So where are you at?

Not that far north you are but we often start riding at -20C, usually have to travel 200kms to a race so the engine is at ambient temp then.
Injection takes care of most of it on the husa 570, itll start easy even at really low temps, what I meant was dont get the light weight battery, itll be a problem child with winter temps, and for gods sake dont pin the starter like in the vid, get upset seeing that as a tip

Well here it gets max-10c and that is very rare
When I don't ride for a long time in winter I get my lithium battery out of the bike (its not in a heated garage).
And keep the battery in room temperature had the (skyrich) lithium battery for some time now and no problems with it I gues I already have it 3-4 years
Don't know how many years of use I can get out of it but a normal battery is mostly dead after 5-6 years and a yuasa OEM battery costs more than a lithium one so I wille take lithium because of the weight

Hope to not veer off-topic too far, but some of the lithium battery manufacturers say to just turn on a headlight to warm up the battery The KTM SX doesn't have that option so I guess they have to resort to the mash-starter/take-nap procedure

Once talking to a know how guy designing chargers for the lithium ones he said theres no problem storing them cold, just dont charge them below 7 or above 28 degrees C roughly. Also important, do not feed them over 14,5V.
Stay away from that and the battery itself should be fine. I have one on my roadracing trackbike and works just fine (skyrich too), however for winter use its not a good idea.

I'm glad it's freakin hot where I live, 40 Celsius at 11:30 am yesterday. I noticed in winter at 10C the cold cranking was poor so I went 130 cca to 220cca. Anyway bugger this battery business, like husabelg says, how is it goin ?
