The Ultimate Nissan Leaf e+ Battery Replacement Guide
Is your Nissan Leaf e+ showing signs of aging? If you’re facing drastically reduced range, dashboard warnings, or simply want to breathe new life into your electric vehicle, you’ve likely considered a battery replacement. However, the high cost of Original Equipment Manufacturer (OEM) batteries can be a significant barrier.
This guide is designed to walk you through the process of replacing your Leaf e+ battery, focusing on maximizing value, range, and reliability. We will explore why upgrading to a high-quality aftermarket solution, specifically using brand-new CATL cells, is often the superior choice for savvy EV owners.
Why Replace Your Leaf e+ Battery?
The Nissan Leaf e+ (specifically the ZE1 model) is renowned for its efficiency and durability. However, like all lithium-ion batteries, capacity degrades over time.
- Symptoms of Degradation: Reduced range (e.g., dropping below 150-200km), “Reduced Power” warnings, or complete battery failure.
- The OEM Dilemma: Replacing your battery with a brand-new Nissan factory unit can cost upwards of $12,000 to $16,000 USD. Furthermore, the factory might only offer remanufactured units, which come with their own set of risks regarding cell health.
The Superior Alternative: New CATL Cells
At CNS BATTERY, we advocate for replacing your old Leaf e+ pack with a brand-new, high-capacity lithium-ion battery pack built with cells from CATL (Contemporary Amperex Technology Co. Limited), the world’s largest battery manufacturer.
Why CATL Cells?
- Top-Tier Quality: CATL supplies batteries to Tesla, BMW, and Volvo. Their cells offer superior thermal management and energy density compared to older Leaf chemistry.
- Zero Cycle Count: Unlike “refurbished” batteries that reuse old cells, a new CATL pack starts with a clean slate, offering a lifespan far exceeding the original Nissan battery.
- Cost Efficiency: You can achieve 50%+ savings compared to the dealer price while gaining better performance.
Step-by-Step: Your Replacement Journey
Replacing an EV battery is a significant project, but with the right preparation and partner, it is straightforward.
1. Compatibility Check (The VIN Scan)
Before you order, it is crucial to verify your specific Leaf e+ model (ZE1). Nissan made subtle changes over the years.
- Action: Contact our technical experts with your Vehicle Identification Number (VIN). We will confirm the exact voltage, connector type, and mounting dimensions to ensure a perfect fit.
2. Selecting Your Capacity
The Leaf e+ originally came with a 62kWh pack. However, this is your chance to upgrade.
- Standard: 62kWh (Restores original range).
- Extended: 68kWh+ (Available in some configurations, offering even longer range and better cold-weather performance).
3. Logistics & Delivery
Lithium batteries are classified as dangerous goods (UN 3480). We handle all the complex logistics.
- Service: We offer DDP (Delivered Duty Paid) shipping to over 50 countries. This means we manage customs, duties, and insurance. Your battery arrives at your door in a fumigation-free wooden crate, ready for installation.
4. Installation: DIY or Professional?
While we recommend a certified technician for safety, many of our customers successfully perform the swap themselves.
- Time Required: Approximately 1-2 hours for an experienced mechanic.
- Process: It is largely a “Plug-and-Play” procedure. The steps involve disconnecting the 12V, lifting out the old pack, lowering in the new pack, reconnecting cables, and performing a BMS reset or programming.
Expert Tip: Watch our high-definition installation tutorial videos before starting. We provide step-by-step guidance on cable routing and BMS programming to ensure a smooth handover.

Frequently Asked Questions (FAQ)
1. Is it safe to install a non-Nissan battery in my Leaf e+?
Yes, if sourced from a reputable manufacturer. Our batteries are rigorously tested to meet international safety standards (IATA, UN38.3). We use automotive-grade CATL cells with built-in protection against over-current, over-voltage, and short circuits. Our 2-year warranty provides additional peace of mind.
2. Will this void my car’s remaining warranty?
No. A correctly installed aftermarket battery does not void the warranty on other vehicle components (such as the motor or chassis). We recommend keeping your installation records and using a professional garage if you are concerned about dealership policies.
3. How long does the installation take?
For a professional mechanic, the physical swap usually takes 50 minutes to 2 hours. This includes disconnecting the old unit, installing the new one, and running diagnostics. If you are a DIY enthusiast, we provide video call support to guide you through the BMS programming.
4. What is the range after replacement?
With a brand-new 62kWh or 68kWh CATL pack, you can expect to regain the full original range of your Leaf e+ (approximately 230-250 miles EPA, or 340-400 km WLTP), depending on driving conditions and temperature.
