hello,
I own an FXS and following an accident at work I could not charge it for 4 months.
When I wanted to take it back, the battery no longer charges, the dealer tells me that the battery is dead and that it must be changed. :o
I'm surprised we can't recharge it.
Do you have a solution to get it going again?
thx.

Try and get hold of one of the Delta Quiq chargers, those will start charging from a much lower voltage than the built in charger.
-
Thank you for the reply.
You know where I can find this kind of charger and where do I have to plug into the bike?
-
A Zero dealer should be able to order one in, I'm guessing your dealer didn't have one to hand if they didn't try it. Or maybe they did and it didn't work, worth asking them before you put the order in. It plugs into a connector just above the motor (looking from the back of the bike), it's a standardised Anderson connector so you can hook up any other charger that's programmed with the right settings.

OK thanks,
what is the voltage and amperage to charge the battery from this connector?
-
The full charged voltage is 116v and you'll want to keep it under 1C, so 7.2kW for the FXS, but I doubt you'll be spending the money on a charger capable of that. The Quiq charger is 1kW if I remember correctly, so even a little faster than the built in charger and handy to keep hold of if it does fix your problem. You can even use both chargers at once.

I have had to recharge dead lith's before.
STart slow, and it may take half an hour or so but once you get the voltage up to a 'normal' discharged battery voltage, you should be able to use your normal charger on it. GO SLOW for the entire recharge, Lith batteries that were allowed to goto zero can create internal faults that may ruin the battery, if there is an issue it'd be better to find it with a fault code, or something opening up rather than overheating and arcing over and a catastrophic thermal runaway.
The biggest problem if you got a lith battery down to close to zero is the current limiting on the battery charger, most are NOT created with a dead battery recovery mode and will just not start, or almost immediately shut down on over current because of the huge difference in expected .vs. actual battery voltages.
Good Luck.
as a side note, telling the manu / dealer that you bricked your battery probably immediately voids the warranty as well. New batteries won't be cheap and considering YOU let it get that way, they will probably not be nice and just 'give' you a new battery.

Thank you for your answer, 116v in AC or DC?

The 116v is the battery max voltage, which is DC, of course.

this might get you in the right direction for a charger.
