Sv: Nicometer i Nye Think

[jim3cantos]

Hi, I have left the car outside in the cold for 3 days and when I came back it refused to start. Power limit flashing, some weird sounds and the symbol of the battery in red. The car doesn't charge either. I read 10v in 12v battery from OVMS and also windows go up and down very slowly.  From other threads I suspect (and hope) 12v battery is the culprit. Anybody has tried to recharge it using one charger/manteiner connected to the 12v outlet (cigarette lighter) or it should be better to connect directly to the battery? Does the procedure from the image below also apply to zebra Thinks when trying to access to the battery?

Thanks

...Good news. I came back this evening and that the car went "online" OK. I left it plugged this morning and it has charged from 60 to 85% even though it didn't begin to charge when I plugged it. I have just discovered that this one:

...seems to be charging the 12v battery when the car is plugged:

Only then?

Yes, some users have upgraded their car with an external 12V charger to keep the 12V battery in good condition. It helps a lot in cases just like yours.

Wow, I believe  that's a really good SMPS charger.
Prima also plug-in connector and different adapters.
It from 2V battery voltage works (Datasheet)? My device work only above 8 volts.
Cheers

Doesn't this charger (CTEK) come standard in every Think A306? I didn't put it there inside the hood. It came with the car.
