I observe that the more I drive my car, the longer the battery will sit at 100% before it starts to drop off. After a week of no use, the battery SoC will drop to about 80% and then sit there for a long long time. Less temperature related than you may think: the same behavior occurs at 9°C (Winter garage temperature) and 18°C (Summer garage temp). For temperature related issues, you need to get down to freezing point. I parked a 1-year old car for a week when skiing, it sat in the shade at -10°C to -20°C for the entire week, the doors and windows froze closed, I just managed to get one back boor open, and only just managed to start the diesel motor. THAT was a cold battery! Quote:

I complained to CTEK that the displayed graph time intervals are nonsense. The graph should show :00, :05, :15/30/45/60 etc to make it easier for the human mind to understand. But the display issue is nothing to do with the sample period. Quote:

And it will give you peace of mind when on holiday, which is great thing to have!

Thanks Swiss for addressing all the points in your customary thorough manner.
I'm a lot more comfortable now and am pleased I followed your advice in the first place. Make sure you keep warm this winter... Cheers Dave |
