Nissan Leaf AZE0 Battery Upgrade Tutorial: Boost Range for 1st-Gen Models (2010-2017)
Is your Nissan Leaf AZE0 stuck with fading range and outdated battery performance? As the chassis code for first-generation Leaf models (2010-2017), the AZE0 originally came with 24kWh or 30kWh batteries—delivering just 100-175 miles of real-world range 。 After years of use, these packs degrade rapidly, leaving owners frustrated by range anxiety. The good news? A Nissan Leaf AZE0 battery upgrade can double your range and extend your EV’s lifespan. As CNS BATTERY experts, we’ve crafted this step-by-step tutorial to walk you through the process, from kit selection to post-upgrade calibration, ensuring a smooth and successful upgrade.
Nissan Leaf AZE0 Battery Basics: What You Need to Know
Before starting your upgrade, understanding the AZE0’s battery system is critical to avoid compatibility issues. Unlike second-gen Leafs, the AZE0 lacks active thermal management, making battery degradation more pronounced—especially in extreme climates. Here’s what you need to note:
Original Battery Specs
2010-2014 AZE0 models shipped with 24kWh lithium-ion packs (100-120 miles range), while 2015-2017 versions received a 30kWh upgrade (140-175 miles range) 。 Both use Nissan’s AESC cells and basic BMS (Battery Management System), which requires calibration when upgrading to larger packs.
Key Upgrade Compatibility
The AZE0’s chassis and wiring harness can support up to 62kWh batteries, but you’ll need a compatible upgrade kit with BMS reprogramming tools. Avoid direct swaps without calibration—this can trigger error codes and damage the vehicle’s electrical system.
Step-by-Step Nissan Leaf AZE0 Battery Upgrade Tutorial
This tutorial focuses on upgrading your AZE0 from 24kWh/30kWh to a 40kWh or 62kWh pack using CNS BATTERY’s premium upgrade kit. We recommend professional installation, but this guide outlines the core process for transparency.
1. Gather Tools & Upgrade Kit
First, secure a AZE0-specific upgrade kit. CNS BATTERY’s kit includes a high-grade 40kWh/62kWh battery pack (with AESC cells), BMS reprogramming software, wiring harness adapter, mounting brackets, and safety gloves. You’ll also need a hydraulic lift, torque wrench, and battery terminal cleaner.
2. Safety Preparation & Power Disconnect
Safety is paramount. Park the AZE0 on a level surface, engage the parking brake, and disconnect the 12V battery. Wait 10 minutes for the high-voltage system to discharge. Put on insulated gloves (rated for 1000V+) and remove the battery access panel under the rear seat to disconnect the main high-voltage connector.
3. Remove the Original Battery Pack
The AZE0’s battery pack is located under the vehicle. Use a hydraulic lift to raise the car safely, then remove the 16 mounting bolts (torque to 45 N·m) securing the pack. Disconnect the BMS connector and wiring harness, then carefully lower the old pack using a hoist—wear protective gear to avoid injury (the pack weighs ~300 lbs).
4. Install the New Upgrade Pack
Lift the new 40kWh/62kWh pack into position and secure it with the original mounting bolts (reuse or replace with stainless steel bolts for durability). Connect the wiring harness adapter to the vehicle’s BMS port—ensure all connections are tight to prevent short circuits. For 62kWh upgrades, install the additional cooling fan included in the kit to mitigate heat buildup (critical for AZE0’s passive cooling system).
5. BMS Reprogramming & Calibration
This step is non-negotiable for AZE0 models. Connect the BMS reprogramming tool to the OBD-II port and follow the kit’s instructions to sync the new battery with the vehicle’s ECU. Calibrate the SOC (State of Charge) display to ensure accurate range readings—this process takes 30-45 minutes and requires turning the ignition on/off in specific cycles.
6. Post-Upgrade Testing
Reconnect the 12V battery and start the AZE0. Check for dashboard error codes (use an OBD scanner if needed). Test charging with a Level 2 charger—ensure the battery accepts a full charge and charges at the correct rate (40kWh packs should reach 80% in ~2 hours). Take a test drive to verify regenerative braking and acceleration performance.

Benefits of a Nissan Leaf AZE0 Battery Upgrade
Upgrading your AZE0’s battery isn’t just about range—it’s a game-changer for your EV’s value and usability:
1. Eliminate Range Anxiety
A 40kWh or 62kWh upgrade turns the AZE0 from a city car into a road-trip-ready EV. No more planning routes around charging stations or cutting trips short.
2. Extend AZE0 Lifespan by 5-7 Years
Replacing the battery delays the need for a new EV (costing $30k+). The AZE0’s robust chassis and reliability make it worth upgrading, even for older models.
3. Boost Resale Value
A documented battery upgrade increases your AZE0’s resale value by $2,000-$3,000. Buyers prioritize upgraded AZE0s to avoid costly battery replacements.
4. Improved Charging Efficiency
Newer battery cells charge faster than degraded originals. A 40kWh upgrade cuts Level 2 charging time by 30%, getting you back on the road sooner.
FAQs About Nissan Leaf AZE0 Battery Upgrade
Will upgrading my AZE0’s battery void the remaining warranty?
Most AZE0 models are out of Nissan’s 8-year/100,000-mile battery warranty. For vehicles still under warranty, aftermarket upgrades won’t void non-battery component coverage if installed by certified techs like CNS BATTERY’s team.
Can I install the upgrade kit myself?
We don’t recommend it. The AZE0’s high-voltage system poses safety risks, and improper BMS calibration can damage the vehicle. Professional installation takes 4-6 hours and ensures compliance with safety standards.
How long will the upgraded battery last?
CNS BATTERY’s upgrade packs retain 80% SOH after 5-6 years of use. With proper care—avoiding extreme temperatures and frequent DC fast charging—they can last 7+ years, outperforming the original AZE0 battery.
Do I need to replace the charger for the upgrade?
No. The AZE0’s original Level 2 charger is compatible with 40kWh/62kWh packs. However, we recommend using a charger with voltage regulation to extend battery life.
