Top Electrical Part Picks for the 2019–2024 Dodge Charger
1. Battery — Odyssey Performance Series / Optima RedTop
The Charger’s electrical demands — especially on Hellcat and Scat Pack models — require a battery that can handle high cranking amps and sustained power draw. The Odyssey Performance Series and Optima RedTop are perennial favorites among Mopar enthusiasts. Both are AGM (Absorbed Glass Mat) batteries offering superior vibration resistance, longer cycle life, and reliable cold cranking amps (CCA) for those bitter winter mornings.
- Pros: High CCA ratings (up to 950 CCA on Odyssey), spill-proof design, excellent deep cycle capability, longer lifespan than standard batteries
- Cons: Premium price point; require AGM-compatible charger
Fitment Note: Look for Group Size 48 (H6) for most 2019–2024 Charger trims. Hellcat models may benefit from Group Size 94R for extra capacity.

2. Alternator — Remy or AC Delco High-Output
A failing alternator on a Charger is no joke — you’ll notice dimming headlights, a warning light on the dash, and eventually a no-start condition. For 2019–2024 models, Remy and AC Delco produce remanufactured and new alternators that meet or exceed OEM output specs. If you’ve added aftermarket audio, lighting, or a supercharger kit, consider a high-output alternator in the 200–250 amp range.
- Pros: OEM-equivalent or better output, plug-and-play fitment, available in standard and high-output versions
- Cons: High-output units are pricier; installation requires some mechanical know-how

3. Oxygen Sensor — Bosch or Denso
A faulty O2 sensor will tank your fuel economy and throw a check engine light faster than almost anything else. For the Charger’s 3.6L Pentastar V6, 5.7L HEMI, 6.4L 392, and 6.2L Hellcat engines, Bosch and Denso are the gold standard in oxygen sensors. Both brands offer direct OEM-style replacements that plug in without modification. Expect genuine wideband sensors that respond faster and last longer than generic knockoffs.
- Pros: Precise fuel trim readings, improved throttle response, clears CEL codes reliably, direct-fit plugs
- Cons: Upstream vs. downstream location matters — buy the right position; penetrating oil may be needed for stuck sensors

4. Ignition Coils — MSD or Accel
Misfires on a HEMI are embarrassing and wasteful. Upgrading to performance ignition coils from MSD or Accel can restore or even improve your Charger’s spark energy, especially on higher-compression variants like the 6.4L 392 and 6.2L Hellcat. These coil packs are a straight swap for OEM units and are a favorite pairing with upgraded spark plugs during a tune-up.
- Pros: Stronger spark output, improved throttle response, great for modified engines, easy installation
- Cons: Slightly higher cost than OEM replacement coils; HEMI engines need 8 coils (buy a full set)

5. Crankshaft Position Sensor — Standard Motor Products or Delphi
The crankshaft position sensor (CKP) is critical for engine timing. When it starts to fail on your Charger, you’ll experience hard starts, stalling, or no-start conditions. Standard Motor Products and Delphi both make OEM-quality replacements that are precise, durable, and covered by solid warranties. This is a DIY-friendly repair for anyone with basic tools.
- Pros: Exact OEM replacement, restores proper timing signal, affordable price, plug-and-play
- Cons: Access can be tight depending on engine configuration; always clear codes after replacement

Buying Guide: What to Consider Before Purchasing Electrical Parts for Your Charger
Match Your Engine and Trim
The 2019–2024 Dodge Charger came in several powertrain configurations — the 3.6L V6 (SXT, GT), 5.7L HEMI V8 (R/T), 6.4L 392 HEMI (Scat Pack), and the supercharged 6.2L Hellcat/Redeye. Electrical components like sensors, coils, and alternators are not always interchangeable between these engines. Always confirm your exact engine code before ordering.
OEM vs. Aftermarket vs. Remanufactured
- OEM (Mopar): Best fit, usually longest warranty, but highest cost
- Quality Aftermarket (Bosch, Denso, Delphi, Standard Motor): Excellent reliability, competitive pricing, widely available
- Budget Aftermarket: Higher failure rates — avoid for critical electrical components like sensors and alternators
- Remanufactured: Good for starters and alternators from reputable brands; check core charge policies
Warranty Matters
For electrical parts, always look for at least a 1-year warranty. Premium brands like Bosch, Denso, and Remy typically offer 2–3 year or lifetime warranties on select components. Avoid no-name brands with no warranty support.
Read the Fault Codes First
Before replacing any electrical component, plug in an OBD-II scanner to pull fault codes. Replacing parts blindly wastes money. A P0300 misfire code doesn’t always mean bad coils — it could be spark plugs or fuel injectors. Diagnose before you buy.
Brief Installation Overview
Battery Replacement (Easy — 15 Minutes)
Disconnect negative terminal first, then positive. Remove the battery hold-down bracket (usually one bolt). Lift out the old battery, clean the tray, and drop in the new unit. Reconnect positive first, then negative. Reset your clock and any radio presets. On newer Chargers, you may need to register the new battery with a scan tool to reset the BMS (Battery Management System).
Oxygen Sensor Replacement (Easy–Moderate — 30–60 Minutes)
Use an O2 sensor socket (special slotted socket) for clean removal. Apply penetrating oil the night before if the sensor is stuck. Upstream sensors are typically easier to access than downstream sensors near the catalytic converter. Always clear codes after installation.
Ignition Coil Replacement (Easy — 20 Minutes per Coil)
Remove the engine cover if equipped. Unplug the coil connector, remove the single retaining bolt, and pull the coil straight up. Push the new coil firmly onto the spark plug, bolt it down, and reconnect the harness. Replace all 8 coils if you’re replacing one — it’s worth the extra insurance on a HEMI.
FAQ: Electrical Parts for 2019–2024 Dodge Charger
How do I know if my Dodge Charger has a bad alternator?
Common symptoms of a failing alternator on the 2019–2024 Charger include dimming headlights, flickering dashboard lights, a battery warning light, whining or grinding noises from the engine bay, and a dead battery after short drives. Use a multimeter to test voltage at the battery — a healthy alternator should show 13.5–14.7 volts with the engine running.
What battery group size does the 2019–2024 Dodge Charger use?
Most 2019–2024 Dodge Charger models use a Group Size 48 (H6) battery. High-performance models like the Hellcat may use a Group Size 94R for greater capacity. Always verify your owner’s manual or use a parts lookup tool with your VIN to confirm the correct group size for your specific trim and engine.
Can I replace the ignition coils myself on a Dodge Charger HEMI?
Yes, ignition coil replacement on the Charger’s HEMI V8 is one of the more DIY-friendly electrical repairs. You’ll need a basic socket set and about 20–30 minutes per coil. It’s highly recommended to replace all 8 coils at once since they tend to fail around the same mileage. Pair the new coils with fresh spark plugs for best results.
How often should oxygen sensors be replaced on the Dodge Charger?
Oxygen sensors on the 2019–2024 Dodge Charger typically last 60,000–100,000 miles under normal driving conditions. However, if you notice a check engine light, reduced fuel economy, or rough idle before that mileage, have the sensor tested. Upstream sensors (before the catalytic converter) tend to wear out faster than downstream sensors.
Is it worth buying OEM Mopar electrical parts or aftermarket for my Charger?
For most electrical components, quality aftermarket brands like Bosch, Denso, Delphi, and Standard Motor Products offer reliability equal to or better than OEM Mopar parts — often at significantly lower cost. However, for complex modules like the PCM (Powertrain Control Module) or TIPM (Totally Integrated Power Module), sticking with OEM or a reputable remanufacturer is strongly advised to avoid programming headaches.
Final Verdict: Best Electrical Parts for Your 2019–2024 Dodge Charger
Your Dodge Charger is a precision muscle machine, and its electrical system deserves components that match that standard. For batteries, the Odyssey Performance Series or Optima RedTop are hard to beat. For sensors and coils, trust Bosch, Denso, and MSD to keep your engine running crisply. For starters and alternators, go with a reputable name like Remy or AC Delco to avoid repeat repairs.
The golden rule: don’t cheap out on electrical parts. A $15 no-name O2 sensor that fails in 6 months costs you more in the long run than doing it right the first time. Use your VIN to confirm fitment, scan for codes before replacing anything, and when in doubt, consult a Mopar-savvy mechanic. Your Charger will reward you with years of reliable, tire-shredding performance.
