The charger seems to update the temperature compensation only when the mains power is cut off. I assumed that the compensation would adjust throughout the charging process, especially since this charger has been charging a motorcycle battery all winter.
The storage voltage throughout the winter was 13.5v, and now in warmer weather I used the mains power off and the voltage is currently 13.42v.
I have not tested with other models, I have the 5A and 10A versions as well.
The history saving also seems to be somehow faulty as no new cycle came, it says 0 cycles started, 0 completed. No graphics. With the older firmware at least something was saved in the history.
Firmware 3.61 (latest)
