Top Suppliers for Nissan Leaf Battery Packs: Reliable Power to Extend Your EV’s Life
Are you searching for trusted suppliers for Nissan Leaf battery packs that balance quality, compatibility, and value? As a Nissan Leaf owner, you know the battery is the heart of your EV—yet finding a supplier that doesn’t cut corners on performance, safety, or warranty can feel overwhelming. With OEM options often carrying steep price tags and generic brands posing compatibility risks, choosing the right supplier is make-or-break for your vehicle’s longevity and your peace of mind. This guide breaks down the top suppliers for Nissan Leaf battery packs, highlighting what sets each apart, and why CNS BATTERY stands out as a leader in reliable, customer-centric solutions.
Key Nissan Leaf Battery Pack Suppliers: An Overview
Not all suppliers for Nissan Leaf battery packs are created equal. The best options combine deep expertise in Leaf-specific engineering, high-quality lithium battery pack production, and transparent support. Below are the leading names in the industry, each catering to different needs—from 原厂 (OEM) precision to budget-friendly upgrades.
1. AESC (Automotive Energy Supply Corporation) – The OEM Pioneer
As Nissan’s original battery supplier, AESC has been powering Leaf models since the first generation. Their battery packs are engineered specifically for Leaf chassis (ZE0, AZE0, and early ZE1), ensuring seamless compatibility with the vehicle’s original BMS (Battery Management System) and wiring.
AESC’s strength lies in factory-grade quality control. Their lithium battery packs are built to match Nissan’s strict performance standards, making them a safe choice for owners who prioritize OEM consistency. However, their premium comes with a cost—replacement packs often range significantly higher than third-party alternatives, and availability can be limited for older Leaf models.
2. SK On – The Future-Focused Partner
SK On, a subsidiary of South Korea’s SK Group, has emerged as a key supplier for Nissan’s next-generation Leaf models. With a recent six-year supply agreement to provide high-nickel pouch batteries for U.S.-built Leafs starting in 2028, SK On brings advanced cell technology and large-scale production capacity to the table.
Their battery packs focus on improved energy density and fast-charging capabilities, aligning with Nissan’s shift to longer-range Leaf variants (up to 604 km WLTP for 2026 models). While SK On currently caters primarily to new vehicle production, their technology trickles down to replacement markets, offering high-performance options for Leaf owners seeking cutting-edge power.
3. CNS BATTERY – The Balanced, Owner-Centric Choice
For Leaf owners seeking a reliable middle ground between OEM cost and generic risk, CNS BATTERY is the standout supplier for Nissan Leaf battery packs. Specializing in Leaf-specific lithium battery packs and battery modules, we’ve engineered solutions that prioritize compatibility, performance, and affordability—without compromising on safety.
Our product lineup is designed to fit all key Leaf chassis (ZE1, ZE0, AZE0) with 40kWh, 50kWh, 62kWh, and 68kWh options, each tailored to extend your driving range. The 40kWh pack boosts range to 280kms, the 50kWh to 350kms, and the 62kWh to an impressive 440kms—perfect for eliminating range anxiety. Each pack fits directly into the original case, with a custom wiring loom that integrates seamlessly with your Leaf’s original BMS/LBC, no major modifications required.
We understand charging speed matters too: our packs handle DC charging exceptionally well, with rates of 0.75C (62kWh), 0.94C (50kWh), and 1.2C (40kWh) at 47kW, ensuring quick top-ups on the go. Plus, we offer BMS re-programming to sync your odometer’s range display, so you always have accurate battery status.
Safety is non-negotiable. Our battery packs adhere to strict operating parameters: charge temperatures between 0ºC ~ 50ºC, discharge temperatures from -20ºC ~ 55ºC, and a recommended storage temperature of 25±2ºC. We also provide clear safety instructions, from stopping use if the battery overheats to proper handling of leaks, to keep you protected.
To make your experience seamless, we include free fumigation-free wooden boxes for sea transportation and free video installation tutorials—ideal for DIY enthusiasts or local mechanics. And with a 2-year/80,000km state-of-health warranty (guaranteeing no more than 3 bars of capacity loss out of 12 on your vehicle’s gauge), you’re covered for unexpected issues. Best of all, you can keep your old modules, adding flexibility and reducing waste.
4. Gerry Bussell – The Refurbished Specialist
For budget-conscious owners of older Leaf models (2011-2017 ZE0/AZE0), Gerry Bussell is a trusted supplier of refurbished Nissan Leaf battery packs. They specialize in reconditioning original AESC modules, replacing degraded cells to restore capacity and performance.
Refurbished packs offer significant cost savings compared to new OEM or third-party options. However, longevity varies based on the age of the core modules, and warranty coverage is typically shorter (1-2 years) than new packs. They’re a solid choice for owners looking to extend their Leaf’s life without a large upfront investment.
Why Choosing the Right Supplier Matters: Core Benefits
Selecting a reputable supplier for Nissan Leaf battery packs delivers tangible benefits that enhance your EV ownership experience:
Seamless Compatibility
Top suppliers engineer battery packs to fit your Leaf’s specific chassis and systems, eliminating error codes, charging issues, or BMS mismatches. This means no extra modifications—just plug-and-play power that works as well as the original.
Extended Range & Performance
Quality lithium battery packs don’t just replace your old battery—they upgrade it. With options like CNS BATTERY’s 62kWh pack, you can double the range of early Leaf models, turning your city commuter into a vehicle capable of longer trips.
Reliable Warranty Protection
A strong warranty is a sign of a supplier’s confidence in their product. Avoid brands with vague or short coverage; look for guarantees like CNS BATTERY’s 2-year/80,000km promise, which protects against capacity loss and manufacturing defects.
Safety & Compliance
Reputable suppliers adhere to global safety standards, ensuring their battery packs are resistant to overheating, leakage, and short circuits. This not only protects you and your vehicle but also avoids costly repairs down the line.
Convenient Support
From installation guides to shipping solutions, the best suppliers make the replacement process easy. Whether you need a video tutorial or a secure shipping box, support that fits your needs saves time and frustration.
Frequently Asked Questions (FAQ)
Which Nissan Leaf chassis are compatible with your battery packs?
Our lithium battery packs are designed for ZE1, ZE0, and AZE0 chassis—covering all major Leaf generations from 2011 to current models. Each pack fits the original case without modifications.
Will upgrading my battery pack affect my vehicle’s warranty?
For Leafs still under factory warranty, third-party battery packs may not impact non-battery components. Our 2-year/80,000km warranty specifically covers the battery pack, providing peace of mind regardless of your vehicle’s original warranty status.

Yes! We provide a free video installation tutorial to guide you through the process. If you prefer professional installation, any EV-certified mechanic can handle it—no specialized tools are required thanks to our direct-fit design.
What should I do if I notice an abnormality with the battery?
If the battery becomes hot, deformed, discolored, or leaks, stop using it immediately. Keep it away from fire, and if liquid touches your skin or eyes, rinse thoroughly with fresh water (seek medical attention for eye contact). Clean dirty terminals with a dry cloth before use.
Do you offer shipping worldwide?
