When I bought it, I didn’t know anything at all about all these charges, currents, etc. And even now I don’t really know, but I already want more indication of information about processes and status.
However, the device is positioned for dummies who just need the car to start up in the morning. Copes with the task.
And what would I do with all this information? And so it is clear that if a 5-year-old battery began to get tired in winter, then it's time to change it.
The only thing that bothered me a little, at the first use, is that a cold, from frost, battery, after turning on the charging, does not start charging immediately, but after 15-30 minutes. Heats up, I guess. Or waiting for the room to heat up.
The indication does not display this in any way, I did not find it in the instructions. Maybe he didn't read well?
However, the first time I thought the charger was broken. I connected everything, but only the "MODE" button is lit, and nothing else happens. Does not respond to pressing. But, after half an hour, when all the valerian has already been drunk, it starts charging, the corresponding indicator lights up.
