Hello dear forum, two weeks ago I wanted to get my C70 out of the winter break and drove to the underground car park/double parker to replace the vehicles. No sign of life at the C70 when activating the radio key (he has an alarm system…). Well, called the ADAC and he could revive it with a power bench. After that the car drove out of the TG and checked the charging power again at the surface of the earth… the ADAC man measured 63A, what goes out of the light engine in the battery and 9A in the vehicle. He said that this would not be a bad value for an 80Ah battery and meant that I probably didn’t have to change urgently. The battery has a sticker 2016, so I don’t want to complain. After 4-5 years, the things are just through. Now I’m looking for a power bank start aid and a new battery, mine is a lead acid, no AGM. In the TG I don’t want to keep groping around besides starting aid, so that I don’t have to fall under the double parkers. If someone has a tip for start aid/power bank, I don’t want to change the battery for me, I can’t let it be good for the battery.
