When alternator output drops, the battery is forced to compensate — briefly — and then fails early. Common symptoms include:
-
Repeated dead batteries
-
Flickering or dim headlights
-
Charging system warnings
-
Electrical glitches and no-start situations
Replacing the alternator fixes the root cause, not just the symptom.

This alternator was badly built it suck
Just what I needed –
I believe this alternator is already failing. On my way to work this morning the vehicle acted like it was going to stall on me. Had my dash illuminate two times, saying battery saver is turned on. So i will check the alternator tomorrow.
The product was defected, bad quality. I need be compensated/refunded for the Labor cost –
