All vehicles lose value as they age, become worn out, and log more miles. Declining battery “State of Health” is an additional factor to take into account with electric vehicles (SoH). A brand-new automobile will have 100% SoH because this is an estimate of how much charge the battery can hold compared to when it was first produced. It’s advisable to check out SoH before purchasing because it has an impact on how far the car can drive between charges and how long it will be before you need to replace the battery.

Battery State of Health versus year of manufacture
LeafSpy (upper) and dashboard ‘bars’ (lower) for cars are used to measure Nissan Leaf SoH. The percentiles are depicted in the graphs: 50% represents the median (half have greater SoHs, and half have lower SoHs); 5% of the EVs have SoHs below the 5th percentile, while 95% have SoHs above it. When comparing a car to these figures, care must be used because there is ambiguity in the values, especially when estimating the 5% and 95% percentiles.
Be aware that the top (twelfth) bar goes off when the SoH falls to about 85% on the Leaf’s battery health display, which is located on the far right of the dashboard. Following that, the value of each remaining bar approximately equals 6.25% of the charge holding capacity. SoH for a 10-bar Leaf is therefore predicted to be between 72.5 and 78.75% SoH.
The information in this post was compiled using data from the first few days of February 2022, which corresponded to the January 2022 data upload cycle.
The majority of experts suggest that the SoH is significantly more influenced by the car’s age (year of manufacture) than by the amount of travel. The plot below illustrates how SoH and age interact, and it is clear that there is a significant correlation between the two. There is, however, a great deal of variance; for instance, some cars at 3 years old are at 80% SoH, while others are still very close to 100% SoH.
How can a Nissan Leaf battery’s condition be determined?
The actions listed below must be taken in order to obtain a reasonable estimate of the battery health for a Nissan Leaf:
- Activate the automobile.
- You may notice 12 bars that represent the battery’s health and range estimate on the range display screen’s right side.
You must count the number of remaining/gone bars to get an approximate idea of the Nissan Leaf’s battery health. See the illustration below for an example.
Which SOH is ideal for Leaf?
Amount of health (SOH) A Leaf with 12 bars will have a SOH of at least 85%, and each additional bar lost causes the SOH to decrease by 6.5%. The fact that a Leaf with a few years on it still has 12 bars shows that it is not subject to early deterioration.
How long does a Nissan LEAF battery last?
Depending on where you are and what you do, you’ll receive a specific timeline for your car. Extreme heat, frequent recharging (such as twice or three times a day), and city driving all hasten the battery’s depletion. The Nissan LEAF was designed to endure as much of these typical battery killers as possible, so you would have to be very rough on your car before you saw a significant change.
The Nissan LEAF was designed to travel up to 107 miles a day on a highway without recharging (depending on the model you choose.) You may travel up to 90 miles in even the busiest metropolitan traffic without having to worry about running out of juice. The battery will eventually lose power, but the amount of mileage you obtain will steadily decrease. The erosion will probably only have a minimal impact on you because the ordinary American will travel significantly less than the daily maximums. When you take care of your car, the Nissan LEAF battery should last between 8 and 10 years.
How frequently does the Nissan LEAF battery need to be replaced?
Every three to five years, the Nissan LEAF battery needs to be replaced. Given that this is a rather long period of time between services in comparison to other models and their related services, the driver will actually benefit from this.
What makes a good SoH battery?
As previously mentioned, the battery management system’s approach for determining a battery’s SoH is arbitrary.
An application may accept a battery with a SoH of 50% and higher, whereas a more critical application may only allow batteries with a SoH of 90% and above. In a similar vein, the SoH threshold beyond which an application deems a certain battery inappropriate is likewise arbitrary.
[Reference needed] Usually, this has to do with sudden drops in the voltage being supplied and the related power electronics’ inability to function normally as a result.
What is the price of a Nissan LEAF battery replacement?
Additionally, we created a comprehensive LEAF battery replacement tutorial. Although it has some of the same information, going a little deeper might be beneficial.
- A dealership in Canada reportedly gave a 2013 Nissan Leaf owner a quotation for a replacement battery of $15,000 CAD.
- The Nissan Leaf 40 kWh battery costs $5,500, or roughly $137/kWh, which is right in line with the average pricing for 2020, according to a 2020 Greencars assessment.
- It is anticipated that a 62 kWh battery pack will cost between $8,500 and $9,500, or at most $153/kWh.
- Price for a 30 kWh pack is at most $150/kWh and ranges from $3,500 to $4,500.
- Price for a 40 kWh pack was at most $187.5/kWh and varied between $6,500 and $7,500.

How long before needing replacement do EV batteries last?
An electric vehicle obtains its power straight from a large pack of batteries, as opposed to internal combustion engined cars, which get their energy from burning gasoline or fuel.
These resemble an enlarged version of the lithium-ion (Li-ion) battery in your smartphone; however, electric vehicles (EVs) use packs made up of thousands of individual Li-ion cells that cooperate to power the vehicle. Electricity is utilized to change the batteries’ chemical composition while the car is charging. These modifications are then reversed when the vehicle is in motion to create electricity.
Electric car battery technology
While driving, EV batteries go through cycles of “discharge,” and they “charge,” when the car is plugged in. The battery’s ability to keep a charge is affected by how often you repeat this operation. As a result, the distance between charges and the time between trips are reduced. The majority of manufacturers offer a battery guarantee of five to eight years. A battery for an electric vehicle, however, is currently expected to last 1020 years before needing to be replaced.
It’s surprisingly easy to understand how a battery and the car’s electric motor function together.
The wheels are driven by electric motors that are connected to the battery. When you step on the gas, the car immediately supplies the motor with power, which progressively uses up the energy stored in the batteries.
When you release the accelerator, the automobile starts to slow down by turning its forward momentum back into power thanks to the fact that electric motors can also function as generators. This effect is amplified if you apply the brakes. By recovering energy that would otherwise be lost during braking, regenerative braking increases battery life and extends the travel distance of an automobile.
Electric car battery lithium-ion
Electric vehicles and a variety of portable electronics employ lithium-ion (Li-ion) batteries, a type of rechargeable battery. Compared to normal lead-acid or nickel-cadmium rechargeable batteries, they have a higher energy density. As a result, the size of the battery pack as a whole can be decreased by battery makers.
The lightest of all metals is lithium. However, lithium-ion (Li-ion) batteries only have ions and not lithium metal. Ions are atoms or molecules having an electric charge brought on by the loss or gain of one or more electrons, for those who are unsure of what an ion is.
In addition to being safer than many alternatives, lithium-ion batteries must also have safety precautions in place to safeguard consumers in the unlikely case of a battery failure. To protect the batteries during frequent, rapid charging sessions that take place quickly, manufacturers, for example, install charging protections in electric vehicles.
How is a battery for an electric car checked?
There are three simple ways to verify the battery’s charging in the majority of newer electric vehicles.
- by way of the instrument cluster.
- Status Lights for Charging.
- from an app on a remote smartphone.
- EV Charger Types.
What occurs if the battery in a Nissan LEAF dies?
What is more distressing than range anxiety? The guy who kept you engaged during the Scrapheap Challenge series, Robert Llewellyn, claims that range annoyance is worse since it makes you want to run out of battery.
“You might wonder why the hell I would want to do that. Not you. Robert wanted to simply demonstrate what occurs when your Nissan Leaf runs out of electricity so you would know what to anticipate if it did.
Yes, Robert recently decided to abandon his first-generation vehicle and discover what it’s like to run out of “fuel with an electric automobile. Here is the alternative to what happens when a typical car runs on fumes before stopping, which some of you may be familiar with.
Almost 90 miles later, the dashboard displayed a low-energy warning. However, the car kept acting normally, exactly as if its battery was fully charged. For almost 7 miles (11 km), past the “—” range indicator, the dreaded turtle lit up and caused the car to slow down.
In case you’ve never heard of it, when the Nissan Leaf is about to exhaust its battery completely, it enters the “On the instrument panel, a yellow turtle symbol indicated that the vehicle was in crawling mode.
When in turtle mode, the Leaf won’t drive faster than a safe pace of 32 mph (51 km/h), and it will continue for almost a mile before…
To tell you when it will stop, the Leaf won’t produce any jerky motions, unlike a combustion engine that has run out of gasoline. When the electric motor is no longer receiving power, the automobile will begin to coast until its inertia is lost.
Don’t worry, turn on your signal, and look for a safe place to stop if you ever find yourself with the turtle on your dash and the car stops keeping a consistent pace. If you don’t want to get out and push the car, wait until there is a vacant spot to pull into before applying the brakes.
Call roadside assistance or a friend to tow you to the closest charging station or your home so you can plug it in right away. Additionally, avoid totally draining the battery on a regular basis; some owners reported a decrease in range after doing so a few times.
