Vivaro no power, battery new, bridged

Good morning, Monday at shopping. Wants to start the engine, starts, ruptures, goes off. Control lamps start again after another ignition attempt, then very weak flickering until nothing more. With foreign vehicle bridged, jumped immediately, ran impeccable (driving time approx. 30 minutes) to refuel. At the gas station, same problem, short mess in the mouse cinema (control lights) dead again. Friendly petrol station owner fetches battery on latches, with starting aid cables bridged, sc Statement Tankman: Battery broken Home driven, tried again on Tuesday morning. All lamps light up briefly together, flicker together afterwards nothing more. New battery fetched, built in, ignition everything lights up immediately, can also hear power off pump, I think, but lights don’t extinguish as usual (I always wait this off, then I start) I ignite, flicker, light buzzing, violent flickering, everything goes out, light glimmering, then black. uch (so turn on the ignition) everything black, with the ignition switched on very slowly 4 lights first come to glimmer, burn then stable, ignition-dead. Researched all night in the net and thanks to the Super-Foren (of course here primarily ) I now tap on a mass error. Are there similar experiences, or even solutions? I always want to understand this a little bit and describe the reason as well as possible to the workshop. Have already 150 euros for a battery moaned, which I didn’t need. (I was to blame for that myself, but could have checked before, but nevertheless somehow assumed that the old batt. had a Macke) Panning service wanted to arrive from 50 km away, had no test or measuring instruments, wanted to to tow. I refused and agreed with Renault workshop a meeting if it can be started again. Question: Why does it work while bridged, has to do with the circuit (laidally depicted). Spie Does a mass error matter? Thank you for listening Oh yes: old battery on electronic charger, after 20 minutes green and full.
