About the Alternator 110A 12V For 2015 Honda Accord
Alternator failure on a 2015 Honda Accord 2.4L typically shows up as a battery warning light, repeated battery deaths, dimming headlights at idle, or radio resets. As alternator output drops below battery voltage, the vehicle runs off stored battery capacity instead of charging from the alternator, eventually leading to a no-start condition.
A verified used 110A alternator restores reliable charging at a fraction of new dealer pricing. We bench-test every alternator at the 110A target rating, verify bearings, confirm pulley spin (including OWC pulley function where equipped), assess brush wear, and test diode pack continuity. We confirm the 2.4L K24W application against your VIN before shipping.

Will a 2014 or 2016 Accord 2.4L alternator fit my 2015?
Yes typically. Honda used the same 110A alternator across the 9th generation Accord (2013 to 2017) for the 2.4L K24W I4 applications. A 110A alternator sourced from a 2013, 2014, 2016 or 2017 Accord 2.4L donor will typically cross-reference perfectly to your 2015 Accord 2.4L. We verify Honda part number against your VIN before shipping.
I have a 2015 Accord V6 EX-L. Will this 110A alternator fit?
No, do not order this listing. The 2015 Accord V6 (EX-L V6, Touring trims with J35Y6 3.5L V6) uses a different higher-amperage alternator, typically 130A or 150A. The V6 has higher accessory load due to standard premium audio, navigation, heated/ventilated seats and other equipment. The 110A alternator will be undersized for the V6 application and will fail prematurely. Call (240) 301-0095 and we will source the correct V6 alternator for your specific trim.
I have a 2015 Accord Hybrid. Does this apply?
No. The 2015 Accord Hybrid uses a fundamentally different charging system where a DC-to-DC converter from the high-voltage hybrid battery handles the 12V system. The conventional belt-driven alternator is either much smaller or absent on the hybrid variant. This listing does NOT apply to hybrid trim. Call us for separate hybrid charging component sourcing.
How do I install the alternator?
Installation overview: (1) Disconnect battery negative terminal. (2) Release accessory belt tension at tensioner and slip belt off alternator pulley. (3) Disconnect the field connector. (4) Remove B+ stud nut and lift off the heavy battery cable. (5) Unbolt alternator from mounting bracket (typically 2 bolts). (6) Lift alternator out. (7) Install replacement in reverse order. (8) Torque B+ stud nut to spec. (9) Reconnect field connector. (10) Install belt and verify tension. (11) Reconnect battery. (12) Start engine and verify charging at 14.0-14.7V with multimeter. Total time 30 to 60 minutes for the 2.4L application (V6 takes longer due to packaging).
My 2015 Accord 2.4L has battery issues but charging looks OK on a basic test. Could it still be the alternator?
Possibly. Modern multi-circuit testing requires more than just measuring voltage at the battery. Some alternator failure modes show up only under specific load conditions. Diagnostic steps for thorough alternator testing: (1) measure voltage at battery with engine running and no load (should be 14.0-14.7V), (2) measure voltage with high load applied (headlights, A/C max, rear defroster, brake pedal pressed). If voltage drops significantly under load, the alternator is undersized or failing. (3) Use a clamp-on ammeter at the B+ cable to verify amperage output. (4) Check for parasitic drain when key off. Some shops have load testers that simulate worst-case conditions. If basic tests pass but you still have chronic battery issues, an undersized or failing alternator (or aftermarket accessory overload) may still be the cause.
Do you provide OWC (one-way clutch) pulley testing?
Yes. Many 9th gen Accord 2.4L alternators use a one-way clutch pulley (OWC, also called overrunning alternator pulley OAP) to reduce belt vibration during engine speed transitions. We verify OWC pulley function on bench by checking that it engages cleanly in the drive direction (turns the alternator shaft) and spins freely in the coast direction (does not transmit deceleration torque from the engine). A failed OWC pulley causes belt squeal or noise even with a healthy alternator otherwise.
How much does shop installation cost?
Independent shop labor for 2015 Accord 2.4L alternator replacement typically runs $80 to $200 depending on shop rate. Total job cost including the used alternator part: $210 to $330. Dealer pricing for new OEM alternator and labor typically runs $500 to $800. The DIY route saves significant money for owners comfortable with basic mechanical work.
How does shipping work?
Free shipping to all 50 US states. The alternator weighs 9 to 12 lbs and ships in a padded box via UPS or FedEx Ground. Typical transit is 3 to 7 business days from order confirmation. The B+ stud and field connector are protected during transit.
