Product description
Why the Alternator Matters on the Altima
Once the engine is running, the alternator is the main power source for:
-
Engine control modules and ignition
-
CVT electronics and sensors
-
Electric power steering
-
Headlights and exterior lighting
-
HVAC, infotainment, and accessories
-
Charging and maintaining the battery
When alternator output drops, the battery gets forced into doing the alternator’s job — briefly — and then fails early. Symptoms include:
-
Repeated dead batteries
-
Flickering headlights
-
Charging system warnings
-
Electrical glitches and no-start situations
Replacing the alternator fixes the root cause, not the symptom.
Correct 110 Amp Output — Exactly What Nissan Designed
Nissan engineered the Altima 2.5L charging system around a 110-amp alternator to balance electrical demand and long-term reliability. This alternator provides:
-
Stable voltage at idle and cruising speeds
-
Proper battery recharge after cold starts
-
Consistent output with accessories running
-
Reduced stress on wiring and electronics
Not oversized. Not underpowered. Exactly right.
