VelSatis Undervoltage Issue

I'm having undervoltage issues with my 2007 Renault VelSatis gasoline. Poor starting, system failures, flickering headlights, and weak battery. I suspect a bad battery or parasitic draw. Anyone seen this?

The conversation centers around a 2007 Renault VelSatis experiencing undervoltage issues, leading to poor starting, system failures, flickering headlights, and a weak battery. The initial suspicion was a bad battery or parasitic draw. A suggestion was made to check and clean the battery terminal connections for corrosion. Ultimately, the problem was resolved by replacing the faulty battery, as confirmed by a workshop.

Did this summary help you solve your problem?

I had something similar on my VelSatis. Check the battery terminal connections for corrosion. Clean them up good and make sure they're tight. Also, how old is the battery?

Thanks. I'll check the terminals. Was your issue also undervoltage and system failures? Did cleaning the terminals fix it completely?

Cleaning the terminals helped for a bit, but the problem kept coming back. Turned out the battery was just plain shot. Needed a new one. I'd say get it checked at a workshop.

Thanks for the advice. I went to a workshop, and they confirmed the battery was bad and needed replacement. Total cost was 290€.
