Problems with a dead battery in a Renault Captur

I have a 2020 Renault Captur with a gasoline engine and 50,000 km on the odometer. Since last Thursday, I have a new battery, but the car still won't start and the battery keeps going flat. I went to the dealer this morning, but they couldn't find anything and only tightened the terminals. Now the car is again with a flat battery. Does anyone have an idea what the problem might be or what I can still try?

(Translated from Dutch)

A 2020 Renault Captur with a new battery still experiences starting issues and a flat battery. Possible causes include lights or electronic devices staying on, or an alternator not charging the battery properly. Suggested solutions involve checking for any devices left on and testing the alternator's voltage output. If these steps don't resolve the issue, a professional inspection for parasitic drains in the electrical system is recommended.

Check if there are any lights or electronic devices staying on when the car is off, as this could drain the battery. Also, ensure that the alternator is charging the battery properly by testing the voltage with a multimeter; it should read around 13.8 to 14.4 volts when the engine is running. If these checks don't resolve the issue, it might be best to have a professional inspect the electrical system for any parasitic drains. Let me know how it goes or if you have further questions!
