Bosch lights flashing

Hi, recently after a bad weather ride my battery will not charge anymore. I connect it to the charger, it seems to start, but after two seconds three light are flashing.



Reading about the problem seems to indicate wrong pack temperature, but after 12 hours rest and try again no change.

Put it on the bike and it works then but can't charge it. Have tried this reset-trick, holding button for 10 sec, doesn't help.

Anyone know something about this?

Well... I read on a german forum that some person had the same problem and that it was mouisture related.

I have never had problems with the battery before in about 4000 km of riding so I guess maybe some seal is about to give up.

Put in on the living room radiator (medium temp) for a few hours and tried again and now I can charge it! Have only tried charge to storage and put it away for now. But it feels ok now.
