Top Nissan Leaf Battery Suppliers Worldwide: Choose the Best for Your EV Upgrade
Are you struggling to find a reliable battery for your Nissan Leaf upgrade or replacement? With so many suppliers claiming premium quality, it’s hard to tell which one delivers on performance, durability, and compatibility. For Nissan Leaf owners, the right battery supplier can make or break your EV experience—especially when dealing with degraded packs or seeking a range boost. Whether you own a first-generation Leaf or a newer model, knowing the top Nissan Leaf battery suppliers worldwide helps you make an informed decision that protects your investment. As experts at CNS BATTERY, we’re breaking down the leading suppliers, their strengths, and why we stand out for Leaf-specific solutions.
Leading Global Suppliers for Nissan Leaf Batteries
The Nissan Leaf has relied on a handful of trusted battery suppliers since its 2010 launch, with both OEM (Original Equipment Manufacturer) and aftermarket options dominating the market. Each supplier brings unique technologies and advantages, catering to different Leaf owner needs—from factory replacements to high-performance upgrades.
Envision AESC: The Original Nissan Leaf Battery Supplier
Envision AESC (formerly Automotive Energy Supply Corporation) is the cornerstone supplier for Nissan Leaf batteries, with a partnership dating back to the first-generation model. Founded as a joint venture between Nissan and NEC, the company was acquired by China’s Envision Group in 2019, now operating with a 80-20 ownership split (Envision-Nissan). Today, Envision AESC supplies over 90% of the batteries used in Nissan Leaf vehicles globally.
Their lithium-ion battery packs are engineered specifically for Leaf models, featuring seamless integration with the vehicle’s BMS (Battery Management System). Envision AESC is expanding its capabilities, with plans to produce batteries offering 1000km+ range and 30% faster charging by 2024. The supplier also prioritizes sustainability, building carbon-neutral factories powered by solar energy to manufacture its packs. However, recent reports note occasional良品率 (yield rate) issues that have impacted Leaf production, highlighting potential supply chain risks.
CATL: Global Powerhouse for Aftermarket Leaf Upgrades
Contemporary Amperex Technology Co., Limited (CATL) is the world’s largest动力电池 (power battery) supplier, holding a 36.8% global market share in 2023. While not an OEM supplier for Nissan Leaf, CATL’s high-performance lithium-ion batteries are widely used for aftermarket upgrades, especially for owners seeking extended range.
CATL’s packs offer exceptional energy density and durability, backed by partnerships with major automakers like BMW, Volkswagen, and Tesla. For Nissan Leaf owners, CATL’s modules can be adapted for swaps, providing higher capacity than factory packs. The supplier’s advanced thermal management systems reduce degradation, making their batteries suitable for extreme climates. However, CATL’s focus on mass production means limited Leaf-specific customization, requiring additional adapters for seamless integration.
LG Energy Solution: Reliable OEM-Alternative for Leaf Models
LG Energy Solution is a leading South Korean battery supplier with a strong presence in the EV market. While not the primary supplier for Nissan Leaf, LG’s batteries are a popular OEM-alternative for replacement and upgrades, thanks to their consistent performance and strict quality control.
LG’s lithium-ion packs feature robust construction and long cycle life, making them ideal for older Leaf models with degraded batteries. The supplier’s focus on safety—including advanced cell separation technology—minimizes fire risks, a key concern for EV owners. LG also offers global distribution, ensuring easy access to replacement parts. However, their Leaf-specific offerings are limited compared to Envision AESC, and pricing tends to be higher than aftermarket competitors.
CNS BATTERY: Leaf-Specific Expertise for Custom Upgrades
Unlike generalist suppliers, CNS BATTERY specializes exclusively in Nissan Leaf battery solutions, combining OEM-level quality with aftermarket flexibility. As a trusted name in Leaf battery swaps, we focus on solving the unique pain points of Leaf owners—from range anxiety to compatibility issues.
Our batteries are engineered for every Leaf generation (2011–2017 ZOE1 and 2018+ ZE1), with pre-programmed BMS to avoid error codes and ensure 400V voltage compatibility. We prioritize durability with liquid cooling systems (a rare feature in aftermarket packs) and rigorous testing to withstand extreme temperatures and thousands of charge cycles. Unlike Envision AESC’s supply chain risks or CATL’s one-size-fits-all approach, CNS BATTERY offers tailored solutions with 24/7 technical support and a 3-year warranty.
Key Benefits of Choosing the Right Nissan Leaf Battery Supplier
Selecting a top-tier supplier for your Nissan Leaf battery isn’t just about quality—it’s about enhancing your entire EV experience and maximizing your vehicle’s value.
Seamless Compatibility & Performance
Leading suppliers like Envision AESC and CNS BATTERY design batteries specifically for the Nissan Leaf, ensuring perfect integration with the vehicle’s electrical system. This eliminates error codes, optimizes charging speeds, and delivers consistent range—something generic batteries often fail to achieve. A compatible battery also maintains the Leaf’s factory safety features, protecting you and your vehicle.
Long-Term Durability & Cost Savings
Premium suppliers use high-grade lithium-ion cells and advanced thermal management, extending battery lifespan to 8–10 years or 100,000+ miles. This avoids frequent replacements, saving you thousands in the long run. For example, CNS BATTERY’s packs outlast generic alternatives by 30%, making them a cost-effective choice for Leaf owners.
Enhanced Resale Value
A Leaf with a battery from a top supplier commands a higher resale price. Buyers prioritize battery quality and reliability, so upgrading with a pack from Envision AESC, CATL, or CNS BATTERY makes your vehicle stand out in the used market. Many owners recover 50%+ of their upgrade cost when selling.
Why CNS BATTERY Stands Out Among Global Nissan Leaf Suppliers

Frequently Asked Questions (FAQ)
Will a battery from a non-OEM supplier affect my Nissan Leaf’s warranty?
