If you own a Hyundai Kona Electric, or you’re thinking about buying a used one, the question eventually hits: how much does a Hyundai Kona battery replacement cost? When we talk about the big high‑voltage pack that powers the car, you’re usually looking at $6,000–$10,000 or more before any help from warranty or insurance. The good news: most Kona drivers will never pay that out of pocket, especially if you understand how the warranty works and how to shop smart for a used EV.
Quick answer
For the high‑voltage battery in a Hyundai Kona Electric, most U.S. estimates fall between $6,000 and $10,000 for parts and labor at a dealer, with some independent or refurbished options dipping closer to $5,000. The small 12‑volt battery is completely different and typically costs just $150–$300 installed.
Hyundai Kona battery replacement cost overview
Kona Electric battery costs at a glance
Most reputable EV repair cost guides put a full Hyundai Kona Electric battery pack replacement in roughly the same ballpark: about $10,000–$12,000 MSRP for a 64 kWh pack if you bought it outright, with many owners ultimately paying closer to the $6,000–$8,000 range after dealer discounts or alternative sourcing. Labor usually adds another $600–$1,000 depending on the shop and region. In practice, warranty coverage and recall history mean many packs have been replaced at no charge to the driver.
What type of battery are we talking about? HV pack vs. 12-volt
High-voltage traction battery
This is the big lithium‑ion pack under the floor of your Hyundai Kona Electric (39–40 kWh or 64–65 kWh depending on model year). It powers the motor and gives you hundreds of miles of range. Replacing it is the expensive job, thousands of dollars even before labor.
When people search for Hyundai Kona battery replacement cost, this is usually what they mean.
12‑volt auxiliary battery
Just like a gas car, the Kona has a small 12‑volt battery that runs accessories and wakes up the high‑voltage system. When it dies, the car won’t "start," but the fix is simple.
- Typical parts + labor: $150–$300
- Handled by any Hyundai dealer or good independent shop
- Often replaced every 3–5 years
Don’t confuse the two
Many quick quotes online are for the 12‑volt battery, not the high‑voltage pack. If the price is under $400, you’re almost certainly looking at the 12‑volt replacement, not the EV pack that powers the car.
Hyundai Kona EV battery replacement cost breakdown
Let’s break down what goes into a Hyundai Kona EV battery replacement quote when you’re dealing with the high‑voltage pack, not the little 12‑volt battery.
Typical Hyundai Kona Electric battery replacement costs (U.S.)
Approximate out-of-warranty pricing ranges based on recent EV battery cost research and Kona‑specific estimates.
| Cost component | Typical range | What it covers |
|---|---|---|
| New OEM HV battery pack | $4,000 – $7,000 | Factory Hyundai pack for 39–40 kWh or 64–65 kWh models |
| Refurbished or used pack | $3,000 – $6,000 | Salvage or remanufactured pack, often with shorter warranty |
| Labor (dealer) | $600 – $1,000 | 3–6 hours of work plus shop supplies |
| Diagnostic + programming | $150 – $400 | Battery testing, software updates, calibration |
| Taxes & fees | $300 – $800 | Varies by state, shop fees, hazardous‑material handling |
| Total out-of-warranty bill | $6,000 – $10,000+ | What many owners would see on a final invoice without warranty help |
Real‑world invoices will vary by dealer, region, and model year, but these ranges are a reasonable planning guide.
Why the wide range?
Battery pack prices move with the cost of cells, global supply, and whether you’re buying a brand‑new pack from Hyundai or a used or refurbished unit. Location also matters, a large metro dealership with high labor rates will usually quote more than a smaller‑market shop.
How much does the Kona battery warranty actually cover?
Hyundai has leaned heavily on warranty to build confidence in its EVs, and the Kona Electric is no exception. In the U.S., most Kona EVs carry an 8‑year / 100,000‑mile (or more) warranty on the high‑voltage battery, covering defects and excessive capacity loss. Some markets list even longer mileage or special green‑vehicle coverage, but the key takeaway is the same: for the first eight years, many serious battery issues are Hyundai’s problem, not yours.
- If your Kona battery fails or drops below a defined capacity threshold (often around 70%) during the warranty period, Hyundai will typically repair or replace the pack at no cost to you aside from downtime and incidental fees.
- The warranty generally transfers to the next owner, which matters a lot if you’re shopping used.
- You still need to follow Hyundai’s maintenance and software‑update guidance, abuse, improper repairs, or flood damage can void coverage.
What this means in practice
If you own a 2019–2022 Kona Electric that’s been maintained properly and hasn’t been in a major incident, there’s a good chance your high‑voltage battery is still under warranty today. For many owners, the real out‑of‑pocket risk is much lower than the sticker price of a new pack.
Recalls, replacements, and what they mean for you
The Kona Electric has already lived through one of the largest EV battery recalls of the last decade. Early model years (especially 2019–2020) were subject to a global recall because of fire risk tied to specific cells. Many owners received brand‑new redesigned packs under warranty, effectively resetting the clock on battery age.
- If your Kona was part of the recall and had its pack replaced, you’re likely driving on a relatively young battery even if the car itself is several years old.
- A recall replacement doesn’t mean the car is now fragile, quite the opposite. In many cases, the updated pack is more robust than the original design.
- Documentation matters. If you’re buying used, ask for recall paperwork and service records that show when the pack was replaced.
How to check your car’s history
Run the VIN through Hyundai’s recall lookup, review service records, and ask the seller for the latest battery report. At Recharged, every EV we list comes with a Recharged Score battery health report so you can see pack condition, recall status, and charging history before you buy.

Full replacement vs. module repair and used packs
Not every Kona that’s losing range needs an entire new battery. You and your technician usually have three broad paths: full replacement, partial repair, or a used/remanufactured pack.
Your options when a Kona EV battery needs help
Each path has a different mix of cost, risk, and long‑term confidence.
1. Full OEM replacement
What it is: Brand‑new Hyundai pack installed at a dealer or qualified EV shop.
- Cost: Usually $6,000–$10,000+ out of warranty
- Best for: Severe failures, warranty claims, long‑term ownership
- Pros: Maximum reliability, strongest warranty
- Cons: Highest price, car may be totaled by insurance if damage is accident‑related
2. Module‑level repair
What it is: Replacing only defective modules inside the pack, not the entire thing.
- Cost: Often $1,500–$5,000 depending on how many modules are bad
- Best for: Out‑of‑warranty cars with localized cell problems
- Pros: Cheaper than full pack, can restore range
- Cons: Fewer shops are qualified; warranty is usually shorter
3. Used or refurbished pack
What it is: A pack from a salvage Kona or a remanufactured unit.
- Cost: Roughly $3,000–$6,000 plus labor
- Best for: Budget‑conscious owners, older vehicles
- Pros: Big cost savings
- Cons: Unknown history, shorter warranty, may have some degradation
Be wary of DIY pack surgery
High‑voltage batteries can be lethal if handled incorrectly. Opening a Kona pack at home isn’t like changing brake pads, it requires training, specialized tools, and proper safety procedures. It can also void remaining warranty. Leave internal pack work to qualified EV technicians.
Signs your Kona battery may need testing or replacement
Most Kona Electric packs age gracefully, losing a small amount of range each year. But certain symptoms tell you it’s time for a deeper look, and maybe a warranty conversation.
Watch for these Kona battery warning signs
1. Noticeable range loss
If your real‑world range on the same routes and weather has dropped dramatically, say, from 250 miles to 170, without a clear cause, it’s time for a health check.
2. State-of-charge jumping or stuck gauge
The battery percentage suddenly jumps up or down, or stays stuck for a long time and then plummets. That can indicate cell imbalances or BMS issues.
3. EV warning lights or messages
Battery or powertrain warnings on the dash, reduced‑power (limp) mode, or messages about battery protection mode should be taken seriously.
4. Rapid DC fast-charging slowdown
Your Kona suddenly charges much slower than before on the same DC fast charger, even in mild weather, with no obvious station problem.
5. Overheating or strong chemical smells
Unusual heat from the battery area or a sharp, sweet chemical odor is rare but urgent, don’t drive the car; have it inspected immediately.
6. Very early capacity loss
If a relatively young Kona (under 5–6 years, normal mileage) feels like it’s lost a huge chunk of usable range, you may be in warranty‑claim territory.
How to save money, or avoid paying for a pack at all
A five‑figure repair bill is nobody’s idea of fun. The way you charge, maintain, and insure your Kona can dramatically change your odds of ever facing a full battery replacement invoice.
Ways to reduce your Kona battery replacement risk
Focus on driving habits, documentation, and financial backup.
Smart charging habits
- Avoid living at 100% charge; daily charging to 70–80% is gentler on the pack.
- Don’t regularly run the battery to 0%, try to stay above 10–15% when possible.
- Use DC fast charging for trips, not every single commute.
Use warranty and insurance
- Know your battery warranty dates and mileage limit; set a reminder in your calendar.
- If damage comes from a crash or road debris, comprehensive or collision coverage may pick up the tab.
- Document problems early so you have history if you need to make a claim.
Thinking about refinancing or upgrading?
If you’re staring down a potential out‑of‑warranty battery replacement on an older Kona, it may pencil out better to trade into a newer EV with a fresh warranty and healthier pack. Through Recharged, you can explore used EVs with verified battery health and pre‑qualify for financing with no impact on your credit.
Buying a used Hyundai Kona EV? Battery questions to ask
A used Kona Electric can be a fantastic value, especially if it’s had a recall pack replacement or lived most of its life on gentle home charging. But the battery is where the story is, so you want to interview the seller like a detective.
Questions for any seller
- Has the high-voltage battery ever been replaced or repaired? If yes, who did the work and when?
- Was this car part of the recall? Ask for paperwork if a new pack was installed.
- How was it charged? Mostly home Level 2, or DC fast charging every day?
- What’s the typical real-world range? Compare their answer to the original EPA rating.
Data you should see
- Recent battery health report or capacity test.
- Service history showing recall work and software updates.
- Odometer and in-service date to confirm warranty time & mileage left.
- Any aftermarket modifications to charging equipment or wiring.
When you shop through Recharged, every Kona Electric listing includes a Recharged Score battery health report so you don’t have to guess about pack condition.

Frequently asked questions about Kona battery replacement costs
Bottom line: When a Kona battery replacement makes sense
A full Hyundai Kona Electric battery replacement is a big repair, no question. On paper, a $6,000–$10,000 bill looks intimidating. But most Kona owners will never write that check, thanks to robust battery warranties, the massive recall that already gave many cars fresh packs, and the fact that these batteries generally age more slowly than early EV skeptics predicted.
If you keep an eye on range, charge thoughtfully, and document anything unusual, you’ll be in a strong position to lean on Hyundai’s warranty when it counts, or to make a clear decision about repair versus replacement once the car is older. And if you’d rather skip the uncertainty altogether, shopping for a used Kona Electric with verified battery health through Recharged lets you enjoy the car’s punchy performance and low running costs without losing sleep over what’s happening inside the pack.
