Each Pick, Reviewed

The 3 picks below run from $104.99 to $194.99, reviewed in rank order.

PHILTOP Alternator for Honda Accord 2.4L

The PHILTOP Alternator for Honda Accord 2.4L is our primary recommendation because it balances a high 4.3 rating with a construction designed to meet OE standards.

What we like: This unit features pure copper windings and an external insulating coating to improve conductivity and durability. It is rated to withstand operating temperatures from -40C to 105C and meets OE standards for performance. The 110A output ensures the alternator supports the high-output requirements of the 2013-2017 Honda Accord electronics, preventing dimming lights or power loss under heavy load.

Keep in mind: At the $194.99 mark, this is the most expensive option on our list. It is best suited for owners who prioritize long-term endurance and OE-standard testing over the lowest possible upfront cost.

Honda Accord 14489N Alternator

The Honda Accord 14489N Alternator serves as a specialized option featuring a 7-Groove Clutch Pulley and upgraded internal components. We selected this model for buyers who need a specific pulley configuration and are comfortable troubleshooting potential software communication issues.

What we like: This alternator includes a 7-Groove Clutch Pulley and carbon brushes designed for greater starting force. The housing is constructed from die-cast aluminum alloy for better heat dissipation. It provides the 110Amp output necessary to power the 2013-2017 Honda Accord electronics without power drops.

Keep in mind: The upgraded regulator may trigger a “check charging system” error with the vehicle CPU, which requires an OBD tester to clear. This makes it less ideal for buyers who want a completely “plug-and-play” experience without potential diagnostic steps.

Honda Accord 2013-2017 Alternator 14489 31100-5A2

The Honda Accord 2013-2017 Alternator 14489 31100-5A2 is our entry-level selection, offering the most accessible way to restore your vehicle’s charging system. It provides the essential 110A output required for your specific engine and transmission configuration at a competitive price point.

What we like: This unit is priced at $104.99, making it the most budget-friendly choice for a replacement. It features an internal fan and regulator for a compact design and matches the 110A requirement for the 2013-2017 Honda Accord electronics.

Keep in mind: Because this is a budget-oriented unit, it lacks some of the advanced material coatings found in the PHILTOP model. It is best for drivers looking for a cost-effective fix rather than a long-term premium upgrade.

What Separates One Car Alternator From the Next

OEM Part Number Compatibility

Verify the OEM part number to ensure the electrical connector and mounting points match your specific vehicle architecture. The Farrme and PHILTOP units both support the 31100-5A2 and 14489 standards, while the ASTOU unit covers a wider range of codes including A005TL0581 and A5TL0581ZC. You should confirm your specific production year’s number before ordering, as even physically fitting units can have different wiring harness layouts that prevent the vehicle from starting. All three options listed are new production units rather than remanufactured parts, and you should check the specific listing to confirm if the wiring harness is included or if you must swap your original harness over.

Cold Cranking Amps

Cold cranking amps and total amperage determine if the alternator can charge the battery under high-load conditions like the AC or headlights. These units are rated at 110A, which meets the 110Amp requirement for the 2.4L engine. If your vehicle experiences under-amperage, it often results in a failure to charge the battery during startup. The PHILTOP alternator is designed to OE standards to ensure consistent voltage regulation across these loads.

Warranty Coverage Period

Warranty coverage period determines your protection against internal component failure after the initial installation. The PHILTOP alternator is rated for 2000H of endurance and features 96H salt spray resistance, though the specific warranty duration is not listed in the data. Because these are new units rather than rebuilt ones, they offer a different reliability profile than a remanufactured unit with a shorter warranty. You must confirm the specific month-based warranty period with the seller before purchase to ensure coverage for your region.

Pulley Tooth Count

Pulley tooth count is critical because an incorrect pulley size causes belt slippage or premature wear on the serpentine belt. The Farrme model features a 7-groove pulley, while the ASTOU unit includes a 7-groove clutch pulley. The PHILTOP unit uses an SC7 pulley, which is the standard for this application. You must confirm that the pulley design matches your current serpentine belt to avoid a pulley diameter mismatch.

Shipping Weight

Shipping weight is a factor for local delivery, but the weight of the unit itself confirms the use of heavy-duty materials. The PHILTOP alternator utilizes a die-cast aluminum housing and pure copper windings to maintain durability. While specific shipping weights are not provided in the data, the use of aluminum alloy die-cast covers on the ASTOU unit helps manage the weight of the assembly without sacrificing the 110A output.

Who Buys Car Alternators, and What It Really Costs

Questions Buyers Ask Before Choosing

How do I know if my alternator is dead or if it is a belt or fuse issue?

You should check for a loose or frayed serpentine belt and inspect the fuse box for blown fuses before purchasing a replacement. If the belt is slipping or a fuse is blown, replacing the alternator will not resolve the charging issue. If the belt is intact and fuses are secure but the battery still fails to charge, the alternator likely requires replacement.

Will these alternators fit my specific engine size without modifications?

These alternators are specifically designed for the 2.4L 2356CC engine found in the 2013-2017 Honda Accord. Because Honda models in this year range use different engine configurations with unique mounting points, you must confirm your engine displacement before ordering. If your vehicle uses a 3.5L engine, these 110A units will not be compatible without custom modifications.

Which alternator should I buy for a 2013-2017 Honda Accord?

The best choice for a budget-conscious buyer is the PHILTOP Alternator for Honda Accord 2.4L, which offers a 4.3 rating at the $194.99 price point. If you prefer a lower cost entry-level option, the Farrme Honda Accord 2013-2017 Alternator 14489 31100-5A2 provides 110A of power for around $104.99. For those prioritizing a high-rated brand with a 7-Groove Clutch Pulley, the ASTOU Honda Accord 14489N Alternator costs approximately $119.99.

Does the ASTOU alternator require a special installation?

Yes, the ASTOU Honda Accord 14489N Alternator features an upgraded regulator that may trigger a “check charging system” error with the vehicle CPU. You should use an OBD tester to connect to the vehicle and clear the error code if it appears after installation. This unit is a direct replacement for OEM part numbers 311005A2A02 and A005TL0581.

Who Should Skip These Car Alternators

If you need to support high-output heavy-duty electrical draws, none of the options on this page meet the 150A requirement. These alternators provide standard power for the 2.4L engine but lack the overhead for heavy-duty aftermarket accessories.

You should look for a high-output alternator if your vehicle requires more than 110A. For specific high-demand applications, you may need a Tier 1 manufacturer unit designed for heavy-duty loads.
