Nissan Leaf Plus Battery Replacement: The Ultimate Installation Guide
Is your Nissan Leaf Plus struggling to keep up with your daily commute? If the range anxiety is setting in or the dreaded “Turtle Mode” has appeared, it’s likely time for a battery replacement. The Leaf Plus (specifically the AZE0 chassis code) is a powerful vehicle, but its 62kWh battery pack is a complex system that requires precision when replacing or upgrading.
As a leading manufacturer specializing in Nissan and BMW EV batteries, CNS BATTERY understands the intricacies of the Leaf Plus powertrain. We don’t just sell batteries; we provide comprehensive solutions backed by a decade of R&D. This guide is designed to walk you through the process of replacing your Leaf Plus battery, ensuring you get back on the road with maximum range and safety.
🛠️ Why Choose a Complete Replacement?
Before diving into the installation, it’s crucial to understand why a complete battery pack replacement is often the best solution. Many owners attempt to replace individual modules, but this can lead to mismatches in capacity and health, causing long-term BMS (Battery Management System) errors.
A brand-new, factory-standard lithium battery pack ensures:
- Zero Faults: Perfect synchronization between modules and the BMS.
- Maximum Range: Restoring your vehicle to its original 226-mile (EPA) range potential.
- Safety: Eliminating risks associated with mixing old and new cells.
📋 Pre-Installation Checklist
Safety is paramount when working with high-voltage systems. Before you begin, ensure you have the following:
- The New Battery Pack: Specifically, a 62kWh Lithium Battery Pack compatible with the Nissan Leaf Plus (AZE0).
- Tools: Insulated wrenches, torque wrench, jack stands, and insulated gloves.
- Environment: A dry, flat, and well-ventilated workspace.
- Documentation: Your vehicle’s VIN code for compatibility verification.

🔄 Step-by-Step Installation Process
Follow these steps carefully to ensure a seamless swap. This process typically takes 1-2 hours for a professional technician.
1. Disconnect the Vehicle Power
This is the most critical step.
- Open the hood and disconnect the 12V auxiliary battery negative terminal. This cuts power to the vehicle’s control systems.
- Wait at least 10 minutes to allow the capacitors in the inverter and BMS to discharge.
2. Remove the Underbody Cover
- The Leaf Plus battery is protected by a large plastic underbody cover.
- Use a socket wrench to remove the bolts securing the cover. Carefully slide it out from the front of the vehicle.
3. Disconnect the High-Voltage Pack
- Locate the main service disconnect (MSD) or the high-voltage connector on the side of the battery.
- Disconnect the high-voltage cable. Always wear insulated gloves during this step.
4. Unbolt the Battery Mounts
- The battery is secured by 4 main bolts (2 in the front, 2 in the rear) and a central support bracket.
- Use a torque wrench to loosen these bolts. The rear bolts can be tricky to access and may require an extension.
5. Lower the Old Pack & Install the New
- Using a transmission jack or an EV battery trolley, carefully lower the old battery.
- Caution: The Leaf Plus battery weighs approximately 600 lbs (272 kg). Do not attempt to lift it manually.
- Slide the new 62kWh Lithium Battery Pack into place. Ensure the cable routing matches the original path.
6. Reconnect and Torque
- Reinstall the mounting bolts and torque them to the manufacturer’s specification (typically 80-100 Nm).
- Reconnect the high-voltage cable and secure the underbody cover.
💻 Post-Installation: BMS Programming
Once the physical installation is complete, the electronic handshake begins. The Leaf Plus requires the BMS to recognize the new pack.
- Reconnect the 12V: Restore power to the vehicle.
- System Check: Turn the ignition on (do not start the car). The dashboard should display a battery readiness light.
- First Charge: Plug the vehicle into a Level 2 charger. The first charge cycle allows the BMS to balance the cells and calibrate the State of Charge (SOC).
If you encounter any error codes during this phase, our technical support team offers remote video guidance to walk you through the programming process, ensuring a 100% success rate.

❓ Frequently Asked Questions (FAQ)
1. How do I know if my Leaf is a “Plus” model?
The Leaf Plus uses the AZE0 chassis code. You can find this on the VIN plate inside the driver’s side door jamb. Visually, the Plus models have a charging port on the front left fender, whereas standard Leafs have it on the rear bumper.
2. Can I install this battery myself?
Yes. The installation is plug-and-play and follows the OEM standard. However, due to the high voltage and weight of the pack, we strongly recommend having it installed by a certified technician or someone with experience in EV systems. We provide detailed installation videos and manuals to assist you.
3. What is the warranty on the new 62kWh pack?
We offer an industry-leading 2-year or 80,000 km warranty (whichever comes first). This covers defects in materials and workmanship, and we also provide prorated coverage for performance degradation, ensuring your battery maintains at least 70% capacity over the warranty period.
4. How much range will I get with the new battery?
A brand new 62kWh Lithium Battery Pack will restore your Leaf Plus to its original specifications. You can expect approximately 226 miles (EPA) or 364 km of range under optimal conditions. Real-world range will vary based on driving habits and climate.
5. How long does shipping take?
We offer DDP (Delivered Duty Paid) service worldwide. Shipping times vary by region: North America and Europe typically receive their orders within 3-6 weeks via sea freight, or faster via air freight for urgent needs.
