Step-by-Step Nissan Leaf 40kWh Battery Upgrade Tutorial

H3: Pre-Upgrade Preparation

1. Confirm Compatibility: First, verify your Nissan Leaf model (ZE0/AZE0/ZE1) and provide your VIN to CNS BATTERY’s pre-sales team for a free compatibility assessment. This ensures the battery matches your vehicle’s specifications.
2. Gather Tools: You’ll need basic tools including a wrench, screwdriver, and insulated gloves. CNS BATTERY also provides a free installation toolkit with every purchase, including terminal cleaners.
3. Safety First: Park your vehicle in a well-ventilated area, turn off the engine, and disconnect the negative terminal of the 12V battery to prevent electrical accidents.

H3: Installation Process

Option 1: Full Battery Pack Installation (Plug-and-Play)

1. Remove the old battery pack by unscrewing the mounting bolts and disconnecting the power and signal cables.
2. Place the new CNS BATTERY 40kWh pack into the battery compartment. Align the mounting holes with the vehicle’s frame.
3. Connect the plug-and-play connectors—no extra wiring required. The battery is pre-programmed to work with your Leaf’s BMS.
4. Reconnect the 12V battery and start the vehicle. The odometer will automatically display the new range after BMS re-programming.

Option 2: Individual Module Installation

1. Remove the old modules from the battery case. Keep them for future use or recycling.
2. Install the new CNS BATTERY modules (Module A/B/C/D) in the original positions. Each module is labeled for easy alignment.
3. Connect 6 power lines and 1 signal line according to the color-coded instructions in the free video tutorial. Ensure all connections are tight and secure.
4. Close the battery case and perform BMS re-programming using the guidance provided by CNS BATTERY’s technical team.

H3: Post-Installation Check

1. Start the vehicle and check the battery capacity gauge—it should show 12 bars (full capacity).
2. Test the DC fast charging function: the 40kWh battery supports 1.2C charging, meaning it can charge efficiently at 47kW stations.
3. Take a short test drive to confirm smooth acceleration and no error messages on the dashboard.
