CT200h weak battery lights flickering

My 2011 Lexus CT200h hybrid with 170310 km is showing some worrying signs. The battery seems weak when starting, and the lights are flickering occasionally. I've checked the battery voltage and it seems a bit low. Could this be a bad battery sensor?

Hey! I drive a CT200h too. Had similar issues last year: weak starts and the lights dimming. Definitely sounds like a battery issue. Have you checked the voltage sensor specifically? That was my problem.

Yeah, the voltage seems off. Was it just the sensor itself, or did you have any other battery problems at the same time?

For me, replacing the sensor fixed it completely. But if your battery is old, it might be on its way out too. I'd get it checked at a workshop just to be sure. Could save you some headaches later.

Thanks a lot! It was the battery sensor as you suspected. Cost me 315€ to get it replaced. Appreciate the help!
