Hello, I have a bosch c3, as if I bought a new one, I charged it with maybe 5 batteries, but today I wanted to connect and only the blue light on the battery is discharged does not want to detect it. I connected it to a second one in the car and it detected it. It bothered me and I dismantled the rectifier, which turns out a handyman was already sitting with it and did not put other capacitors or anything like that.
