On elbilwiki I found the following under "Hva er feil når..."

La 12volten stå til lading med en intelligent vedlikeholdslader (C-tek for eksempel) før man reiser fra bilen i en lengre periode .

Nothing is mentioned about what SOC the traction battery shall have when parked for a longer period.

NASA also says that connections to each cell must be provided. That is not the case with the Saft STM5-100MRE block.

I shorted the blocks after discharging with a light bulb. After some weeks, a couple of the blocks have devloped a white, hairy-like substance on the positive pole. Someone told me it is crystals. I think this is because some cells in the block are reversed and some are not completely discharged.

I changed two blocks that were reported by PakTrakr to be bad, and one of them had this white substance on negative in the car.
It is only dust. I think this is lye (the electrolyte) that has leaked and dried, rather than Cd-crystals.

I can probably find the information on where to find this info somewhere on elbilwiki but I ask you guys instead.

You have to read the BMS program number with the original diagnostic tool FR-2000 or the nikometer.

I assume that you in this case shorted the whole pack and not on an individual block level ?
Shorting individual cells is obviously impossible on SAFT batteries.

No, I discharged each block with a 12V lightbulb, then shorted each block.

In that case it is strange/weird that the white substance appeared after storing for a few weeks and not on all poles on all blocks. The blocks are stored in the same place.

Jeg har en bil som er langtidslagret over vinter og jeg holder den mellom 30 og 40% ladet med vedlikeholdslader koblet på. Det blir interesant å vite kapasitet av pakken når bilen settes i drift igjen. Jeg antar at noe selvutlading har skjedd og at Paktrakr har tømt noen blokker. Mye overlading skal til før batteripakken er balansert.

Checked today with Nikometer : B111   What does it mean

B111 is a good program. Improvements over earlier programs:
* energy meter more accurate than before
* energy meter does not suddenly drop to 0%
* possibly other improvements which is not noticeable

7A/7 hr maintenence charge with fans on all the time, saves batteries in a profesionel workshop enviorment, but for DIY, B116 is better giving 10A on maintenence charge.

Some confusion here I think. The earliest program one will experience is B111. 10 A maintenance charge. The later version, B116 Charges at 7 to 8 A and has a more stable energy meter.
