If you own a Hyundai Ioniq, you’ve probably heard that the battery is the most expensive part of the car. When the pack eventually wears out, the obvious question is: what is the Hyundai Ioniq battery replacement cost, and is it worth paying? In this guide, we’ll walk through real‑world price ranges for Ioniq Hybrid, Plug‑In Hybrid, and Electric/Ioniq 5 models, explain your warranty coverage, and help you decide whether to replace the battery or move into a different EV instead.
Quick takeaway
For most Hyundai Ioniq owners, a full high‑voltage battery replacement will land somewhere between $2,800 and $16,000 installed, depending on model, battery size, and whether you choose a new or refurbished pack.
Overview: Typical Hyundai Ioniq Battery Replacement Costs
Real‑world Ioniq battery cost ranges
Those headline numbers are just the starting point. Your actual Hyundai Ioniq battery replacement cost will depend on four big variables: whether you drive a Hybrid, Plug‑In, or full Electric model; if the car is still under warranty; whether you choose a brand‑new OEM pack or a refurbished unit; and local labor rates. Let’s break it down by model so you can get a realistic picture for your specific Ioniq.
Hyundai Ioniq Battery Types by Model
Ioniq Hybrid (2017–2022)
The original Ioniq Hybrid uses a small high‑voltage lithium‑ion polymer pack (roughly 1.56 kWh). It assists the gasoline engine rather than powering the car on electricity alone for long distances.
- Battery lives in the rear of the vehicle.
- Far cheaper to replace than a full EV pack.
- Car can still move (slowly) with a weak pack, but performance and fuel economy suffer.
Ioniq Plug‑In Hybrid & Electric
The Ioniq Plug‑In Hybrid adds a much larger pack (about 8.9 kWh) for meaningful electric‑only range. The original Ioniq Electric and the newer Ioniq 5 use even larger packs more comparable to other EVs.
- Plug‑In Hybrid: still has a gas engine, but the car can run EV‑only for commutes.
- Ioniq Electric: full battery EV with earlier‑generation packs.
- Ioniq 5: modern, high‑capacity pack (up to 77 kWh) and more complex cooling and electronics.
Know which battery you’re pricing
Every Ioniq also has a 12‑volt accessory battery that’s relatively cheap (often under $300 installed). The big numbers in this article refer to the high‑voltage drive battery, which is an entirely different component.
Hyundai Ioniq Hybrid Battery Replacement Cost
When people ask about Hyundai Ioniq battery replacement cost, they’re often thinking about the first‑generation Ioniq Hybrid (2017–2022). This car’s traction battery is small compared with a full EV, and that keeps costs somewhat manageable.
Typical cost ranges: Ioniq Hybrid high‑voltage battery
Real‑world pricing based on independent repair estimates and refurbished pack suppliers for 2017–2019 Ioniq Hybrid models.
| Option | What it is | Estimated Parts Cost | Estimated Installed Cost |
|---|---|---|---|
| Refurbished/remanufactured pack | Used pack that’s been tested, balanced, and reconditioned by a specialist | $1,500 – $3,000 | $2,800 – $4,500 |
| New OEM pack from Hyundai | Brand‑new factory battery ordered through a Hyundai dealer | $4,500 – $6,000+ | $6,000 – $7,000+ in many U.S. markets |
| Used pack from a recycler | Pack pulled from a salvaged Ioniq with lower miles | $1,200 – $2,500 | $2,200 – $3,800 (varies widely) |
Your exact cost depends heavily on whether you choose new OEM parts or a refurbished pack.
As of late 2025, some independent hybrid‑battery shops list remanufactured 2017–2019 Ioniq Hybrid packs around $3,000 plus installation, while mainstream repair estimators put a brand‑new high‑voltage battery replacement for a 2017 Ioniq Hybrid in the $6,300–$6,500 range before taxes and fees. That’s a big spread, and it’s why you’ll want multiple quotes if you’re out of warranty.
Dealer vs. independent shop
A Hyundai dealer will usually insist on a brand‑new OEM battery and may quote the highest total replacement cost, but you get full factory parts and warranty. Independent hybrid‑battery specialists can be thousands cheaper with refurbished packs, but may offer shorter warranties and more variable long‑term reliability.
Hyundai Ioniq Plug‑In Hybrid Battery Replacement Cost
The Ioniq Plug‑In Hybrid (PHEV) carries a much larger battery than the regular hybrid, so replacement costs climb accordingly. You’re still dealing with a dual‑powertrain vehicle (gas + electric), but the pack has to support meaningful EV‑only driving.
- Most plug‑in replacement quotes land between $8,600 and $13,000 installed when out of warranty.
- Parts alone for a new plug‑in pack can easily be $7,000+, depending on model year and availability.
- Refurbished or used PHEV packs are less common than hybrid packs, so discount options may be limited in some regions.
Because of those higher costs, a plug‑in hybrid battery replacement can force a tough decision on an older Ioniq PHEV: do you put five figures into a car that might only be worth slightly more than the repair, or is it time to move on? We’ll walk through that decision a bit later.
Ioniq Electric and Ioniq 5 Battery Replacement Cost
Once you move into the Ioniq Electric and Ioniq 5, you’re talking about full battery‑electric vehicles. Their packs are many times larger than the hybrid’s, and they’re the single most expensive component in the car.
What full EV owners should expect
These are ballpark figures for out‑of‑warranty replacements in the U.S. as of late 2025.
Ioniq Electric (earlier EV)
Early Ioniq Electric models use smaller packs than today’s EVs, but replacements are still not cheap.
- Typical high‑voltage battery replacement: $12,000–$15,000 installed.
- Limited availability of new packs can drive prices higher.
- Used or refurbished packs may reduce that by a few thousand dollars.
Ioniq 5 (modern EV)
The Ioniq 5 uses a high‑capacity pack (up to ~77 kWh) with advanced cooling and power electronics.
- Full pack replacement often quoted in the $13,000–$16,000 range.
- Module‑level repairs are sometimes possible but not always supported by dealers.
- Because the car is newer, many failures today are still handled under warranty.
Important reality check
On an older Ioniq Electric or a high‑mileage Ioniq 5 that’s out of warranty, a five‑figure battery bill can easily exceed the car’s market value. In those cases, replacing the pack may not make financial sense unless you’re committed to keeping the car for many more years.

Warranty Coverage on Hyundai Ioniq Batteries
Before you panic about a big repair bill, you need to know where you stand on battery warranty coverage. Hyundai has been aggressive with hybrid and EV warranties, especially on earlier Ioniq models.
Hyundai Ioniq battery warranty basics
1. Hybrid & PHEV coverage
In the U.S., most Hyundai hybrid and plug‑in hybrid batteries are covered for up to <strong>10 years or 100,000 miles</strong> against defects. Some markets and specific early hybrid programs also advertised lifetime coverage for the original owner.
2. EV (Ioniq Electric & Ioniq 5) coverage
Hyundai typically backs EV batteries for <strong>10 years / 100,000 miles</strong> (sometimes expressed as 10 years / 160,000 km) with a minimum capacity guarantee, often around 70% state of health, while under warranty.
3. CARB states bonus
If your Ioniq was sold and registered in a state that follows California’s emissions rules, hybrid and PHEV batteries sometimes get <strong>extended warranty coverage</strong>, such as 10 years / 150,000 miles. Always confirm with your dealer using your VIN.
4. What’s actually covered
Warranties usually cover <strong>defects in materials or workmanship</strong> and excessive early degradation. They don’t cover damage from accidents, flood, abuse, or modifications.
5. Transferability
Most Hyundai battery warranties are transferable to subsequent owners within the warranty period, though special lifetime promises on early hybrids were often limited to the original owner. Check your warranty booklet for your model year.
Why warranty status matters
If your Ioniq battery fails within the warranty period, Hyundai will typically replace or repair it at no charge. That’s why you should always check warranty status before paying anything out‑of‑pocket for a battery pack.
Signs Your Ioniq Battery May Need Replacement
The good news is that most Ioniq batteries don’t suddenly die overnight. They usually show a pattern of gradual degradation or recurring faults before an outright failure. Catching these signs early can give you more options, including warranty coverage or selling the vehicle before a major bill arrives.
- Noticeable loss of EV range (Electric/Ioniq 5 or Plug‑In) compared with when the car was new, especially if it drops quickly over one or two years.
- Frequent warning lights related to the hybrid or EV system, particularly battery‑related trouble codes that return after being cleared.
- The car refusing to go into EV mode or frequently kicking the engine on in light‑load situations in an Ioniq Hybrid or Plug‑In.
- Unusual behaviors while charging, stopping early, overheating, or taking much longer than usual to reach a given percentage.
- Dealer or independent diagnostics showing state of health (SOH) well below warranty thresholds, or modules with voltages that are badly out of balance.
Get a proper battery health report
A quick scan of dash lights isn’t enough. Ask for a detailed battery health report that shows capacity, module balance, and any trouble codes. At Recharged, every vehicle gets a Recharged Score with verified battery health so you’re not guessing about the pack’s true condition.
Repair, Replace, or Sell Your Ioniq? How to Decide
Once you know your Hyundai Ioniq battery replacement cost and warranty status, you’re left with a practical question: Do you repair the car or move on? The right answer depends on how those costs compare with the vehicle’s current and future value.
When replacement usually makes sense
- Your Ioniq is still under warranty, and the pack is replaced at no cost.
- The car is in excellent shape otherwise, with low mileage and clean history.
- You can install a refurbished hybrid pack for a few thousand dollars, and the car will be kept for several more years.
- The market value of the car after the repair will clearly exceed what you paid for the battery.
When it’s smarter to move on
- Your quote for an EV pack (Ioniq Electric or Ioniq 5) is $12,000+ and the car isn’t worth much more than that.
- The car has other upcoming needs, tires, brakes, cosmetic issues, that push total spending even higher.
- You’re ready for more range or newer tech and don’t plan to keep the car long enough to amortize a big battery bill.
- You can sell or trade the Ioniq as‑is and put that money toward a newer, warrantied EV.
Think in terms of cost per year
Instead of just looking at the battery quote, ask: How many more years of driving am I buying with this money? If a $3,000 hybrid pack gives you five solid years, that’s $600 per year. A $14,000 EV pack on an aging car is a very different equation.
