The Prius is the hybrid most people picture when they worry about a battery bill, and the fear is usually bigger than the bill. A Prius hybrid battery is one of the least expensive hybrid packs to replace, several honest options exist at different prices, and many cars are still under Toyota’s long battery warranty. A good share of “dead Prius battery” calls also turn out to be the small 12-volt battery, which is a much cheaper fix.
This guide covers what a Prius hybrid battery costs for each generation, the difference between genuine, new-cell, remanufactured and reconditioned packs, when the warranty pays instead, and how to tell a failing hybrid pack from a flat 12-volt battery.
Here is how the options compare for the most common Prius models:
| Option | What You Get | Typical Cost |
|---|---|---|
| Under Toyota’s hybrid battery warranty | Repair or replacement by a Toyota dealer | $0 |
| Genuine Toyota pack, part only | New Toyota pack; refundable core charge extra | About $2,700 to $3,300 list, before labor |
| New-cell pack, independent specialist | Pack built with new cells, often installed | About $2,100 installed, with a multi-year warranty |
| Remanufactured pack | Tested, matched used modules, shorter warranty | About $1,000 to $1,400 installed |
| Reconditioning your own pack | Modules cycled and balanced, weak ones swapped | Usually the cheapest, shortest-lived fix |
| 12-volt battery (often mistaken for the hybrid pack) | Small auxiliary battery that starts the system | A fraction of any hybrid pack price |
Pull over safely if the Prius loses drive power, shuts down its hybrid system while moving, or you smell burning or see smoke. Turn it off, get out and call for help. A hybrid warning with the car still driving normally is not an emergency, but book a diagnosis promptly; a weak pack makes the engine and inverter work harder the longer it is driven.
Is Your Prius Battery Still Under Warranty?
Check this before paying anything. For model year 2020 and later Toyota hybrids, including every Prius, Toyota’s hybrid battery warranty runs 10 years from the date of first use or 150,000 miles, whichever comes first. Earlier model years had 8 years or 100,000 miles. Toyota says the coverage transfers to every later owner, and its warranty page confirms the 10-year, 150,000-mile hybrid battery coverage. The inverter and the hybrid control modules are covered separately for 8 years or 100,000 miles.
In practice that means:
- 2020 and later Prius: covered for 10 years from first use or 150,000 miles. A 2020 Prius first sold in 2020 is covered until 2030 unless it passes 150,000 miles first.
- 2019 and earlier Prius: the 8-year, 100,000-mile coverage has now expired on most of these cars, so a replacement is usually the owner’s cost.
A Toyota dealer can confirm coverage from the VIN, and our Toyota hybrid battery warranty guide explains what is and is not included. If a hybrid warning appears near the limit, report it before the date or mileage runs out and keep the record.
Prius Battery Replacement Cost by Generation
Prices below come from a Toyota parts catalog and a national independent specialist’s listed prices, checked in October 2026. Genuine Toyota pack prices are for the part only and carry a $1,350 core charge, refunded when the old pack is returned. Dealer labor is extra.
Second Generation (2004 to 2009)
The genuine Toyota pack listed for 2004 to 2009 Prius models (part G9510-47031) has an MSRP of $3,300, sold at $3,178.74. An independent new-cell pack for these years is listed at $2,099 with installation and a 48-month warranty, and a remanufactured high-capacity pack at $1,399 with a 24-month warranty. On a car this old, the independent options are usually the better value.
Third Generation (2010 to 2015)
The genuine Toyota pack listed for 2010 and 2011 Prius models (part G9510-47060) has an MSRP of $2,729.35, sold at $2,156.70. Later third-generation cars can use a different part number, so confirm with your VIN. Independent options mirror the second generation: a new-cell pack at $2,099 installed with a 48-month warranty, or a remanufactured pack at $1,399 installed with 24 months.
Fourth Generation (2016 to 2022)
The genuine Toyota pack listed for 2016 to 2021 Prius models (part G9510-47130, also listed for the 2020 and 2021 Corolla Hybrid) has an MSRP of $2,750, sold at $2,172.80. The same independent specialist lists 2016 to 2022 Prius options from $1,250 to $2,250 depending on the type. Note that 2020 to 2022 models in this generation are still inside Toyota’s 10-year hybrid battery warranty.
Fifth Generation (2023 and Later)
The current Prius is fully covered by the 10-year, 150,000-mile hybrid battery warranty, so an out-of-pocket replacement is not a realistic concern for some years yet.
Prius c, Prius v and Prius Prime
The smaller Prius c and larger Prius v use different packs. The independent specialist lists new-cell Prius c packs at $1,999 installed with a 36-month warranty, remanufactured Prius c packs at $1,395 with 18 months, and new-cell Prius v packs at $2,099 installed with 48 months. The plug-in Prius Prime has a much larger battery: 2017 to 2022 Prius Prime packs are listed at $4,995 with new cells or $2,495 remanufactured.
New, Remanufactured or Reconditioned?
Shops use these words loosely, so ask exactly what you are buying:
- Genuine Toyota pack: new, made by Toyota, usually fitted by a dealer. The most expensive route once labor is added, and the most predictable.
- New-cell pack: built by an independent company with new cells or modules. Often around the same price as a genuine pack bought at a discount, with warranties of 3 to 4 years.
- Remanufactured pack: made from used modules that have been tested, matched and balanced. Cheaper, but the cells have already aged, and warranties are typically 12 to 24 months.
- Reconditioning: your own pack is removed, cycled, balanced and any failed modules are swapped. It can restore a pack that has drifted out of balance, but it does not reverse the age of the cells, so it suits a car you will only keep a short while.
- Used pack: pulled from a salvage car with unknown history. Cheapest, and the biggest gamble.
For a Prius you plan to keep for several more years, a new-cell or genuine pack usually works out cheaper per year of use than a remanufactured one, despite the higher upfront price. For a high-mileage car you expect to sell soon, a remanufactured pack is a reasonable compromise. Our wider guide to hybrid battery replacement cost compares the same options across Toyota, Lexus, Honda and Ford.
Is It the Hybrid Battery or the 12-Volt Battery?
Every Prius has two batteries. The large hybrid pack drives the electric motor. A small 12-volt auxiliary battery powers the computers and is needed to start the hybrid system at all. When the 12-volt battery is weak, the Prius may refuse to go into READY mode, the dash may light up with unrelated warnings, or nothing happens when you press the power button. That looks like a hybrid battery failure and usually is not.
Signs that point to the 12-volt battery:
- The car will not start at all, or the dash goes dark or flickers when you press the power button.
- Problems appear after the car has sat for days or weeks unused.
- The car starts and drives normally once it has been jump-started.
Signs that point to the hybrid pack:
- The car starts and drives, but fuel economy has dropped noticeably.
- The battery gauge swings quickly between high and low, and the engine runs more often.
- A hybrid system warning appears while driving, often with reduced power.
Test the 12-volt battery first; it is quick and cheap. Use the jump-start points and procedure in your owner’s manual, since the connection points on a Prius may not be where you expect. If the dash is showing a hybrid system message, our guide to the Check Hybrid System warning covers the other causes, including the inverter faults Toyota extended coverage for on 2010 to 2017 Prius models.
How Long Does a Prius Battery Last?
Long enough that most owners never think about it until the car is well over a decade old. Toyota’s 10-year, 150,000-mile warranty on current models is a floor rather than a ceiling. Many Prius models use nickel-metal hydride packs, which the Department of Energy’s Alternative Fuels Data Center describes as having a much longer life cycle than lead-acid batteries. It also lists heat generation at high temperatures among their main challenges. Heat and a blocked battery cooling intake are the biggest shorteners of pack life. Our guide to how long hybrid batteries last covers the warning signs and what to check before buying a used hybrid.
What to Ask Before You Pay
- What are the trouble codes, and what are the module voltages? A pack with one weak module behaves differently from one that has aged evenly, and the answer affects whether repair or replacement makes sense.
- Was the 12-volt battery tested?
- Was the battery cooling fan and intake checked? A clogged intake overheats the pack and can kill a new one early.
- Is the pack new, new-cell, remanufactured or reconditioned, and what does the warranty cover? Get it in writing.
- Is the core charge included or refunded? On the Toyota parts listings above it is $1,350.
- Is installation included? Many independent prices include it; dealer part prices do not.
Is It Worth Replacing a Prius Battery?
On most Prius models, yes. A Prius with a healthy pack is usually worth noticeably more than the cost of the repair, and the rest of the drivetrain is generally long-lived when maintained. The case weakens on an old, very high-mileage car with other major problems, where a remanufactured pack or selling the car to a hybrid specialist as it is may make more sense. Keep the paperwork either way. A documented new pack is a strong selling point.
Frequently Asked Questions
How much does it cost to replace a Prius battery?
Typically about $1,000 to $2,100 installed at independent specialists, depending on the generation and whether the pack is remanufactured or new-cell. A genuine Toyota pack lists at about $2,700 to $3,300 for the part alone, plus labor and a refundable $1,350 core charge. Under Toyota’s hybrid battery warranty it costs nothing.
Is the Prius hybrid battery covered by warranty?
For 2020 and later models, yes: 10 years from first use or 150,000 miles, whichever comes first, and it transfers to later owners. Earlier models had 8 years or 100,000 miles, which has now expired on most of those cars.
Is a refurbished Prius battery worth it?
It can be for a car you will keep only a short time. Remanufactured packs use tested used modules and cost less, typically around $1,000 to $1,400 installed, but carry 12- to 24-month warranties. New-cell packs cost more and usually come with 3 to 4 years of cover.
How do I know if my Prius hybrid battery is bad?
Common signs are falling fuel economy, a battery gauge that swings quickly between high and low, the engine running more often, weaker acceleration and eventually a hybrid system warning. If the car will not start at all, test the 12-volt battery first.
Why won’t my Prius go into READY?
Most often a weak 12-volt auxiliary battery, which powers the computers that start the hybrid system. It is far cheaper than the hybrid pack. If the 12-volt battery tests fine, have the hybrid system fault codes read.
How long does a Prius battery last?
Typically well over 10 years. Toyota warrants current Prius hybrid batteries for 10 years or 150,000 miles, and many packs last longer. Heat and a blocked battery cooling intake shorten life the most.
