Nissan Leaf e+ 62kWh Battery Replacement Guide: Expert Steps & Safety Tips (2026)
Are you a Nissan Leaf e+ owner dealing with a degraded 62kWh battery, unsure how to navigate a safe, effective replacement? The Leaf e+’s 62kWh high-density battery delivers exceptional 385km WLTP range, but after 5+ years of use, many owners face capacity loss, charging issues, or error codes. A Nissan Leaf e+ 62kWh battery replacement requires precision—this model’s advanced 400V system, integrated BMS (Battery Management System), and unique battery packaging demand specialized knowledge. As CNS BATTERY experts, we’ve crafted a step-by-step guide tailored to the Leaf e+, covering safety protocols, replacement steps, compatible batteries, and why our solutions outperform OEM and generic options. This guide ensures you restore your Leaf e+’s range and performance without costly mistakes.
Key Details About the Nissan Leaf e+ 62kWh Battery
The Nissan Leaf e+ (2020+) is equipped with a 62kWh lithium-ion battery pack, engineered for extended range and compatibility with the model’s 400V electrical system. Understanding its specs is critical for a successful replacement:
-
Technical Specifications: 400V nominal voltage, 288 pouch-style cells arranged in modules, weight of 168kg (370lbs), and thermal management via passive air cooling (optimized for high-density cells).
-
Degradation Signs: Common red flags include range drop below 300km WLTP (22% capacity loss), frequent “Battery Health” alerts, slow DC fast charging (taking over 60 minutes for 80% charge), and inconsistent regenerative braking.
-
Safety Standards: The 62kWh pack meets UN38.3 and IEC 62133 certifications. Replacements must match these standards to avoid fire risks or system malfunctions.
Pre-Replacement Safety Protocols (Non-Negotiable)
Working with the Leaf e+’s 400V system demands strict safety measures. Skip these steps at your peril—electrical shock or thermal events can cause severe injury:
1. Disconnect High-Voltage Power
Park the Leaf e+ on a level surface, turn off the ignition, and engage the parking brake. Open the hood, locate the 12V battery, and disconnect the negative terminal first. Wait 10 minutes for the high-voltage capacitor to discharge—use a non-contact high-voltage tester (1000V-rated) to confirm no residual voltage before proceeding.
2. Essential Safety Gear
Wear Class 00+ insulated gloves (1000V-rated, ANSI/IEC certified), a flame-resistant jacket (NFPA 70E standard), and a face shield. Avoid loose clothing or jewelry—even small metal items can cause short circuits.
3. Workspace Preparation
Work in a well-ventilated area, away from flammable materials. Use a hydraulic floor jack (2-ton minimum) with rubber pads to lift the vehicle, and secure it with 3-ton jack stands (never rely on the jack alone). Have a fire extinguisher (Class D for lithium-ion) nearby.
Step-by-Step Nissan Leaf e+ 62kWh Battery Replacement
This process takes 3-4 hours for professionals; allocate extra time if you’re a DIYer. Ensure you have Leaf e+-specific tools (400V-compliant insulated pliers, CONSULT-4 BMS tool) before starting:
Step 1: Remove Underbody Covers & Components
Remove the plastic underbody covers using a 10mm socket wrench—these protect the battery pack from debris. Disconnect the high-voltage wiring harness (located at the front of the battery) using insulated pliers; label connectors to avoid misalignment during reinstallation.
Step 2: Extract the Old 62kWh Battery
The battery is secured by 12 mounting bolts (14mm) torqued to 55 N·m. Use a torque wrench to remove them, then attach a battery lifting hoist to the pack’s designated lift points. Slowly lift the battery (168kg) and place it on a locking dolly for transport—never drag or tip the pack, as this damages cells.
Step 3: Inspect & Prepare the Battery Compartment
Clean the compartment with a brass wire brush to remove corrosion or debris. Inspect wiring harnesses for wear—replace any frayed cables to prevent future issues. Apply a thin layer of anti-seize compound to the mounting bolt threads for easy removal in future maintenance.
Step 4: Install the New 62kWh Battery
Use the hoist to lower the new battery into the compartment, aligning it with the mounting holes. Tighten the 12 bolts to 55 N·m (follow a crisscross pattern to ensure even pressure). Reconnect the high-voltage wiring harness, ensuring connectors click into place—loose connections cause error codes.
Step 5: BMS Calibration & System Testing
Reconnect the 12V battery negative terminal. Use a Leaf e+-specific BMS tool (CONSULT-4) to reprogram the system to recognize the new battery. Run a full diagnostic test to verify charging functionality, range estimates, and regenerative braking. Test DC fast charging to ensure the battery accepts 47kW as designed.
Best 62kWh Battery Replacements for Nissan Leaf e+
Not all replacements are compatible with the Leaf e+’s 400V system. Below are our expert-recommended options:
1. CNS BATTERY 62kWh Direct Replacement (Top Choice)
Our pack is engineered exclusively for the Leaf e+, using 100% new CATL NCM cells (3,000+ charge cycles). Key benefits:
-
Total all-in cost: $8,800-$9,500 (includes battery, installation, BMS calibration, and $300 core credit).
-
Restores 385km WLTP range and 47kW DC fast charging speed; thermal resistance (-20°C to 55°C) outperforms OEM.
-
2-year/80,000km warranty and free post-installation diagnostics—peace of mind for Leaf e+ owners.
2. Nissan OEM 62kWh Battery (Costly Option)
Priced $16,000-$18,000 all-in, OEM batteries offer 100% compatibility but poor value. They use the same cells as the original (1,500-2,000 charge cycles) and lack the durability of our CATL-powered packs.
3. Remanufactured 62kWh Battery (Risky Gamble)
Priced $7,500-$8,500, these packs use refurbished cells with 4-5 year lifespans. They often lack Leaf e+-specific BMS calibration, leading to charging errors and reduced range.

Frequently Asked Questions (FAQ) About Leaf e+ 62kWh Replacement
Q1: Will replacing my Leaf e+’s battery void the warranty?
If your Leaf e+ is under Nissan’s 8-year/100,000km factory warranty, third-party replacements may affect battery coverage. Our 2-year warranty matches OEM protection, and we provide documentation to safeguard non-battery components (motor, electronics).
Q2: Can I replace the 62kWh battery myself?
DIY replacement is not recommended for the Leaf e+. The 400V system and 168kg battery pose safety risks, and improper BMS calibration can damage the vehicle. Our professional installation ensures safety and performance.
Q3: How long will a new 62kWh battery last in my Leaf e+?
Our CNS BATTERY pack lasts 8-10 years (3,000+ charge cycles) with proper maintenance. Avoid extreme temperatures and keep charge levels between 20%-80% to maximize lifespan.
Q4: Does the replacement battery qualify for eco-rebates?
Yes. Many regions offer $200-$500 rebates for high-efficiency EV batteries. Our 62kWh packs qualify, as they use new, energy-dense cells that reduce carbon emissions.
