I was following your other thread concerning your bike's charge problems, but when Ken offered assistance by explaining what you were probably doing wrong when testing it, you never followed up with results.

Are you now saying that your bike charge system was functioning correctly and that the battery was defective? What was the result?

Statistically, most anything can fail, but I've been pleased with my Shorai. So much so that I swapped a year old one into a new bike.

After I got the bike back home, I recharged the Shorai battery, and it had 14.3 or so volts, but not enough power to crank.
I swapped the old Yuasa battery back in and it fired right up, but wasn't charging.
I've been too busy with work to diagnose it further. I am upgrading the R/R with a MOSFET unit, so I have been working on the wiring for that.
I have off on Tuesday, so I should be able to figure out then what's going on.

Was your Shorai out of warranty? I'm also curious what's going on; I've seen two now that have been deep discharged and come back okay. One was the result of a failed charging system (my bike) and the other the result of parasitic drain over time (friend's DR-Z400).

Cheers,

It is 20 months old. They have a 24 month warranty, but I don't think they cover discharges under the warranty.

They absolutely should. Cycling a battery is a normal everyday occurrence and if it won't come back then there's a problem with it. I'd follow up...

I completely agree with you!

From their website:

Quote:
Conditions Not Covered

Opening the battery case will void the warranty
Applications Not listed on the Shorai website product finder such as: Custom V-Twin Bikes, Aircraft, Automotive, Total Loss (no alternator), Motive power (LFX as power source).
Over-voltage charging, or other error by charger or user setting of charger.
Use in excess of cranking (CCA) specifications
Short circuit of main terminals or BMS port
Improper connections to the 5-pin BMS port
Over-discharge (i.e. resting voltage allowed to fall below 12.8V/6.4V for Lfx 12V/6V types)
Physical Damage to the pack occurring after purchase (impact, water/salt corrosion, etc)
When I got the bike home, the voltage was around 10.5, well below the 12.8v that they list as covered by warranty!

I'll file a claim and see what they say!

What lawyer wrote those conditions up? Below 12.8 volts? That's a joke! Each cell in a flooded lead acid battery is capable of producing 2.100 volts per (x 6 cells), which equals 12.6 volts. This is at a 100% SOC (state of charge). An AGM battery is supposed to produce 2.125 volts per cell making it slightly higher - 12.75 volts. Again, this is at 100% SOC.
12.8 volts is equal to 2.133v per cell (which seems high to me). So, if your battery ever falls below a 100% SOC you've voided the warranty? I call shenanigans...

Put in a warranty claim. The only way to tell if a battery has been deeply discharged would be to completely disassemble the battery, test the electrolyte, test the plates, analyze the lead and make a decision. And no company is going to do all that for a warranty claim on a powersports battery.

But, getting back to my O.P.; if a Flooded Lead Acid battery should NOT be used in our Sprint ST's because of its orientation, then why does Triumph have one in there from the factory? That is my quandary....

The Shorai batteries are lithium iron, not lead acid. Very different chemistry, very different voltage curve.

Caddydaddy, mine was much less than 20 months old when it went, but Shorai was more than fair with me. They sent me the next size up for free within a few days; IIRC I was to send my old one back in the box the new one came in.

Free? Their website lists that I'd get one at 50% off, at the age it is now.
