If your Toyota Prius car’s battery pack dies before the 150,000 (or 100,000) mile warranty expires, the auto manufacturer will replace it for free. But if your vehicle’s warranty is up, you’ll join the 500 or so Prius owners every month experiencing the same dilemma.


When decreased performance and a dashboard warning light signal it is time to visit your Toyota dealership, you have to make a tough choice. Do you buy a new battery pack? Or do you buy a new car?


Thankfully, we’ve got you covered. Here’s everything you need to know about Toyota Prius battery replacement costs.


Understanding the Hybrid Battery


A hybrid car battery is like any other battery. However, it is rechargeable and has enough juice to keep your car chugging along for mile after mile.


A hybrid vehicle utilizes a combination of an internal combustion engine and a battery electric drive system to deliver great fuel economy and drastically reduce emissions.


The Toyota Prius car’s electric motor powers your vehicle, drawing power from the battery. When driving 15 miles per hour or below, the car will only use the electric motor for power. When you’re cruising down the highway at a normal pace, only the gasoline engine is used.


During heavy acceleration, the hybrid car’s electric motor and gasoline engine will work together to increase power to the wheels. This is possible because of the power-split transmission, which combines the torque that each system puts out. 


When you apply pressure to the brakes to slow down or come to a stop your Toyota Prius will utilize a clever system known as “regenerative braking.” Since the car is slowing down, it won’t need to keep the electric motor or gas engine running. Your car will stop delivering power to the wheels and enables the spinning wheels to power its generator. This then creates electricity that is stored in the battery to use at a later date.


When your car comes to a complete stop, both the gas engine and the electric motor will turn off. The Toyota Prius hybrid will use the battery power to run its auxiliary systems, including the radio, cabin light, and air conditioning or heat.


How Long Does a Hybrid Battery Last?


The life of your Toyota Prius battery is not definite because it depends on how far you drive and the conditions that you are driving in. However, the battery warranty will last for either 10 years or 150,000 in states that have California emission laws. In all of the other states, coverage on your Toyota Prius battery is goof for 100,000 miles or eight years. This means that if your battery dies within the warranty period, you will receive a new one with no out-of-pocket costs.


How Does a Toyota Prius Compare to Other Hybrids on the Market?


Despite the Toyota Prius hybrid being one of the first widely marketed and popular hybrid vehicles, there are plenty of other hybrid options available on the market today, in a wide array of makes and models. So, how does the Toyota Prius stand up to its competitors? Firstly, you need to know that there are two types of hybrid vehicles, including full hybrids and plug-in ones.


The main difference between these two types of hybrids is the way the battery charges. A full hybrid charges from a huge battery pack that draws power from the gasoline engine and the brakes. The plug-in hybrids can be just that, plugged in.


The Toyota Prius’ battery is made up of 28 Panasonic nickel-metal hydride modules, each containing six 1.2-volt cells. Connected in a series, they will produce a total of 201.6 volts. This is compared to the Lexus RX 400h which can deliver 500 volts.


Toyota Prius Battery Pack Problems


There are over 1.3 million Toyota hybrids on U.S. roadways, indicating that the number of failing battery pack incidents will rise dramatically during the coming years. But what are the warning signs that drivers should keep an eye out for that show their battery is dying?


Here are some symptoms of a failing Toyota hybrid battery to keep an eye out for:


  • Decreased miles per gallon (MPG): Although there are other issues that can disrupt the efficiency of your fuel efficiency, it is most likely going to be a problem with your battery. If you begin to notice a steady decrease in your miles per gallon for no reason, it’s in your best interest to contact an experienced Toyota hybrid mechanic right away to schedule a health check.


  • Your internal combustion engine is running more than it usually does: If your Toyota Prius sedan’s internal combustion engine (ICE) begins kicking in more often than it typically does, this is another big symptom of a bad hybrid battery. If it runs at odd times or for longer than expected, you could have a failing battery.


  • State of charge: If you look at the screen and notice huge fluctuations in your state of charge (SOC), it’s a definite sign that either your battery or the car’s charging system is having problems. Moreover, large swings in your charge rate point to a bad battery.


  • Unexplained drop in battery bars: Are you noticing a decrease in your hybrid’s battery bars with little to no usage? If you park your car and have full bars and then come back to it with only one bar left, there’s an underlying issue with the battery and it needs to be looked at right away.


  • Weird engine noises: If you notice unusual engine sounds coming from your Toyota Prius, this is because its engine is running more than it typically does. This could indicate that your car is suffering from a failing battery.


If you notice any of the above signs or symptoms, you should take your car into a hybrid mechanic right away for a proper diagnosis and repair.

Why is a Toyota Prius Battery So Expensive?


You may be asking yourself why is the cost so steep for a new Prius hybrid battery. The simple answer to this question is that hybrids have one-of-a-kind batteries and other mechanical components. The Toyota Prius hybrid car runs on two kinds of energy, including an electric motor and the traditional combustion engine. Furthermore, they need a hybrid battery pack to store extra energy.

Due to this, a Toyota Prius car’s mechanical parts are extremely complex. They are also costlier to produce. This is because the parts are often produced in small quantities.

  • 2012 – 2016 Toyota Prius C – $3,807


Each of the aforementioned prices will be reduced by a $1,350 core credit for the old battery pack that is being replaced, which the dealer will then recycle through the long-established Toyota program.


How to Make a Toyota Prius Battery Last Longer


There are some simple steps that you can take to extend the life of your Toyota Prius’ battery. These include:


  • Ensuring that you have the HEV battery pack cooling system checked, cleaned, and certified annually.
  • Every 15,000 miles, or 12 to 15 months, locate the cabin air filter (a part that is in every motor vehicle) and have it serviced or replaced. If the cabin air filter becomes too dirty or clogged, it will affect the air flow to the battery pack, making it run less efficiently.
