Leaf Spy is an application that allows you to connect to your Nissan Leaf to track the car’s information for performance from its computer.
Leaf Spy is commonly used when you want to know the status of your battery’s health.
In this article, we are going to cover the following:
- Equipment used with the Leaf Spy.
- How to use the Leaf Spy.
- What information you should expect to get from the Leaf Spy app?
- The best way to use the Leaf Spy.
Equipment used with the Leaf Spy
There are two key things that you will need when you want to use the Leaf Spy. They include;
- OBD-II dongle.
- Leaf Spy app.
In order to access the vehicle’s computer through the Leaf Spy, you need to have an Onboard Diagnostic Tool (OBD-II) dongle.
Its main function is to act as the medium that feeds you information from the vehicle’s computer system through the Leaf Spy app on your smartphone.
ODB-II works well with all types of vehicles from 1996 to date.
There are two types of OBD-II dongles to choose from. These include;
- Bluetooth OBD-II.
- WIFI OBD-II.
They all work the same way but differ in the method of connection.
Whether you want a WIFI or Bluetooth OBD-II dongle is up to you.
However, the Bluetooth OBD-II is slightly cheaper than the WIFI OBD-II.
If you decide to go with the Bluetooth OBD-II, I would suggest you have a look at this OBD-II on Amazon.
After getting the OBD-II, you will need to have software to connect it. That software is the Leaf Spy for the Nissan Leaf.
This takes us to the next step.
NOTE: Before you install the OBD-II make sure the car is turned on already.

Install the LeafSpy on your phone
The leaf Spy Leaf can be found both on the iOS Play Store and the Android Play Store.
Android allows you to choose between Leaf Spy’s 3 versions; Leaf Spy Lite (free), Leaf Spy, and Leaf Spy Pro.
However, you have only one option in the iOS Play Store, which is LeafSpy Pro.
What’s the difference between Leaf Spy and Leaf Spy Pro
Leaf Spy is for Nissan Leaf models that are from 2011 to 2017 whereas the Leaf Spy Pro is for Nissan Leaf models that are from 2018 onwards.
The Leaf Spy is cheaper than the Leaf Spy Pro.
If you are looking to buy a used Nissan Leaf, I would recommend you get the Leaf Spy Lite(free version). It will give you just enough information about the battery’s health.
See what to check before buying a used Nissan Leaf (Nissan Leaf Inspection).
So, now that you have the OBD-II and Leaf Spy installed we can now talk about how to use the Leaf Spy app on your phone.
1. Make sure the Nissan Leaf is ON.
2. Insert the OBD-II in the vehicle.

How to use the Leaf Spy.
STEP 1: Go to your phone’s settings and connect the Leaf Spy with the OBD-II.
Note that, if you bought a Bluetooth OBDI you will have to go to the Bluetooth settings. And the same case applies to the WIFI OBDI for wifi settings.
Step 2: Open the Leaf Spy app on your phone.
I recommend that once you open the app, you go to the app’s settings. Then set it based on your preferences and check whether the information is correct.
Some of the features that you will find in the settings include:
- The vehicle’s battery size.
- Model year.
- Units (Celsius or Fahrenheit, miles or kilometers, Bar, PSI, or kPa).
- Tire pressure.
NOTE: Ensure that the right battery size and model year is exactly what you see on the settings.

How to know whether the OBD-II is connected to your Leaf Spy app
On the app, you will see a green status indicating that you are connected.
Once it is connected, you will be able to see the vehicle’s information loading on the app.
What will happen if you leave the app running while driving?
The app will give you real-time data, like a live feed of the battery, and will also automatically calculate your trip.

What information you should expect to get from the Leaf Spy app?
The following is the information that you will find on the Leaf Spy app once it is successfully connected to your Nissan Leaf:
(i) Battery Cells
On the Battery Cells, you should expect to find the following information:
- Battery stats (Bat Sts).
This gives you the AHr, State Of Health (SOH) of your battery, odometer reading, and the number of quick charging and Level 1 & 2 charging, etc.
- Battery cell graph.
- Lines on the graph.
Each line on the graph represents the battery cells of your Nissan Leaf.
When you see the red lines, it means the battery cells are trying to balance themselves out, especially after a long drive.
- On top of the graph, you will see mV.
This number shows the difference between the highest and the lowest battery cell in your Nissan Leaf.
- The temperature of the battery.
- The State of Charge (SOC)

(ii) Graphs (Voltage Histogram)
This shows you the voltage differences between the battery cells.
The lesser the battery voltage the more charge the car can hold.
In this graph, you will be able to see the max voltage difference.
NOTE: You can tap on this graph to view the next graph.
(iii) Battery Temperature Graph
This graph shows you the different battery temperatures, on all your battery sensors.
(iv) Charging power graph.
This graph will show you how you charge and how you use the charge.
