|herveyw||Shorai in my 916 for the last few years, quite happy with it as the bike fires up much more readily compared with the old Yuasa (which spat acid over the frame). I don't care about cold weather starting, this is a fair weather only bike. I either disconnect or use the Shorai charger in store mode over the winter, then charge mode one time when spring comes.|

|Brushpuppy||Shorai here too. My battery is 3 years old and right where I want it to be. I do the same as Chuckracer and disconnect the hot lead. Over the long winter months just monitor the charge condition. I very occasionally give the idle battery a bit of a trickle charge for part of a day. Seems to work for me.|

|Chuckracer||Shorai batteries WILL hold a charge for an extended period of time...provided your bike does not have a parasitic draw and Ducatis are notorious for parasitic draw. If it's going to sit, no matter the battery, unhook the hot lead.|

Yuasa batteries have always served me well. I see no reason to switch to a battery that requires constant charging & a warming up period for cold weather, especially at double the cost.
Lead acid batteries arte simple ...and provven..that being said the Shorai Battery chemistry has its own appeal...though not for everyone..
I have used them for several years..with good results.
My issue with them has been the charger...it fried twio batteries before I replaced it...I have a new charger ready for its replacement Shorai!
I got about 3 years out of them...went back to AGM last fall
I also added a digital voltmeter to monitor the battery,charge state ...also adds peace of mind

If you HAVE to rely on a charger them something is wrong, good cables with good contacts good ground should be all you need. Put some rpms to it when it sits for a while when you are warming it up between extended non use. Turn off the high beams and all other power users (GPS PHONES RADAR DETECTORS HEATED GEAR etc.) for some time before you get home. And somes revs in the driveway before shutting down. I wouldn't buy a special charger.
On power tool batteries when they are DEAD dead I have seen videos where you jump just 2
of the multiple contacts from a good battery for just a minute then they charged normally!??? Worth a try ?

|Redcoat||That's good to hear. I will take another chance & buy one for st3s, but I do not plan to trickle charge or float charge as it will be ridden every week to two weeks - some things are still possible in CA.|

Started the multi after months of sitting. Battery is 3+ years old. 12.8 V reading on dash before cranking, fired right up with some mild cranking. When I bought it I put it on trickle charge for a short time maybe 1/2 hour or so. Gas was a month or 2 old, max. Fresh fuel after siphoning the "stale gas"out, bike is in a heated garage.
I am under the impression that it should hold a charge for extended periods of time. I do start the bike at least every couple of months and run it till the fans activate. So far so good

I was considering a Shorai for the 2006 ST3s abs, but after having a 1 year old Shorai crap out on the 2008 Triumph Tiger abs, I am looking closely at LT Snyder's recommendation on Bike Master Gel or Li ion, p. 132 4th edition.
Details of failure. I bought the Shorai 12/2017 since I wanted a battery that could stay dormant for 2 weeks and still start the bike. For over 2 years, it always started every week to 2 weeks and I never had to wait to "warm" up in the SF Bay Area (40-100F) or leave it on a tender.
In Dec. of 2018, I bought a Deltran dual Acid/Lithium Battery Tender specifically for the lead acid battery of the newly purchased ST3s. Then, I decided to connect it to the Tiger's Lithium battery using the dual mode set to Lithium. No charging just float mode as the indicator light was not flashing.
The next morning, the head lights did not light and turning the key over, there was zero power. I check the voltage with a meter and it was 2 volts.
There are some possible other explanations, but my gut tells me that the float mode of the Deltran Battery Tender in Li mode may have overcharged my Shorai. Or, the battery just coincidentally crapped out after 2 years.
