206 Electric leakage

I took it to the electrician today, the signal arm was malfunctioning, I changed it, and when I was gone I said I would look at the leak. He put on the gauges, said a number like 2.4 and said there was a leak. He said that if you don't ride 10 15 days, it will end like that. What should I do? I'm not always a car rider, but I only ride once a week. I had taken it to another electrician before, that leak did not mean that the battery was weak. I was in a dilemma.

There is no original tape in my vehicle. It also goes into sleep mode.
I think you can have another electrician look at it or do not bother.
If your battery is at least 2 years old, replace it.

Yes, I have an ordinary navitech tape in me for 2 minutes after the contact is closed. Then the car goes to sleep. (The light in kilometer turns off after 2 minutes.)
