Primastar Weak Battery

Hey, I have a 2013 Nissan Primastar with a gasoline engine. Recently, I've been noticing a weak battery when starting, and the lights are flickering. My multimeter shows low voltage, and battery tests are inconclusive. Suspect it's the battery sensor, anyone else run into this?

A 2013 Nissan Primastar owner experienced weak battery performance and flickering lights, suspecting a faulty battery sensor. Initial checks showed low voltage, and battery tests were inconclusive. After confirming clean terminals and cables, the issue was resolved by replacing the faulty battery sensor, restoring normal function.

Did this summary help you solve your problem?

I had similar issues with my Primastar. Weak starts and flickering lights... Did you check the battery terminals and cables for corrosion or loose connections?

Terminals and cables are clean. Voltage drops considerably under load, even after charging. Could a faulty sensor really cause such a noticeable drain? Is it even worth looking at the sensor or just replace the whole battery?

Yep, turned out to be a bad battery sensor. It was messing with the charging system. Probably best to get it checked at a workshop if you are not able to do it yourself.

Thanks, I appreciate the confirmation. Just got it back from the shop – faulty battery sensor it was! 315€ later and it's running perfectly again.
