Top Suppliers for Nissan Leaf 62kWh Packs: Trusted Brands for Reliable Replacements
Are you searching for top suppliers for Nissan Leaf 62kWh packs to replace a degraded battery in your Leaf e+ (2019-2023 models)? With the 62kWh pack being exclusive to the high-range Leaf e+ variant, finding a supplier that delivers compatibility, safety, and performance is critical. Many Leaf e+ owners struggle with inconsistent quality from generic vendors or exorbitant prices from dealerships, leaving them stuck between risk and overspending. As CNS BATTERY’s EV experts, we’ve curated the leading suppliers for Nissan Leaf 62kWh packs, backed by industry credentials, user reviews, and technical rigor, to help you make a confident, cost-effective choice.
Key Criteria for Evaluating Nissan Leaf 62kWh Pack Suppliers
Not all suppliers of 62kWh packs meet the strict standards required for Nissan Leaf e+ compatibility. The top suppliers distinguish themselves by adhering to non-negotiable criteria that ensure safety, longevity, and seamless integration with your EV.
• Cell Quality & Certification: Premium suppliers use NMC (nickel-manganese-cobalt) cells—matching the Leaf e+’s original specifications—with ISO 9001 and IEC 62133 certifications. Avoid suppliers using low-grade LFP cells that lack energy density. • ZE1-Specific Engineering: The Leaf e+ (ZE1 platform) requires packs calibrated to its advanced BMS and thermal management system. Top suppliers offer ZE1-optimized designs, not one-size-fits-all solutions. • Warranty & Support: Reliable suppliers back their packs with 2-5 year warranties and post-installation support, including BMS recalibration. • Transparent Testing: Leading brands provide third-party test reports verifying cycle life (1,000+ charges), SOH (state of health) retention, and thermal stability.
Top 4 Suppliers for Nissan Leaf 62kWh Packs
Below are the most trusted suppliers, ranked by quality, value, and Leaf e+ compatibility. Each has a proven track record of delivering reliable 62kWh packs for Nissan’s high-range EV.
1. CNS BATTERY (Best Overall for Value & Compatibility)
As a leading specialist in Nissan Leaf batteries, CNS BATTERY stands out as the top choice for 62kWh packs, with a 4.8/5 star rating from 500+ Leaf e+ owners. Our OEM-equivalent and remanufactured 62kWh packs are engineered exclusively for the Leaf e+ ZE1 platform, using A-grade NMC cells sourced from CATL—one of the world’s largest EV cell manufacturers.
Our 62kWh OEM-equivalent packs ($12,500-$15,000) deliver 90%+ SOH, 3-year warranties, and seamless integration with the Leaf e+’s fast-charging system (20-80% charge in 45 minutes). The remanufactured option ($8,000-$12,000) reuses viable components from original packs, undergoes 15+ safety tests, and includes free BMS calibration. Unlike generic suppliers, we offer end-to-end support, including professional installation and core credits ($200-$400), eliminating hidden costs.
2. AESC (Genuine OEM Supplier & Nissan Partner)
Automotive Energy Supply Corporation (AESC)—a joint venture between Nissan and Envision Group—is the original supplier of 62kWh packs for the Leaf e+. As the OEM supplier, AESC’s packs ($17,000-$19,500) are identical to the factory-installed batteries, ensuring 100% compatibility and a 5-year Nissan warranty.
AESC’s 62kWh packs use proprietary NMC cells with enhanced thermal resistance, addressing the minor良品率 challenges the supplier faced in 2025. They’re ideal for owners prioritizing exact factory specifications and dealership-backed support, though the premium price reflects Nissan’s branding and overhead costs. AESC packs are available exclusively through Nissan dealerships or authorized distributors.
3. Greentec Auto (Top Aftermarket Remanufacturer)
Greentec Auto is a trusted name in EV battery remanufacturing, with a 4.6/5 star rating for its Nissan Leaf 62kWh packs. Priced at $9,500-$13,000, their remanufactured packs reuse original AESC modules, replace worn cells with OEM-grade units, and undergo rigorous BMS recalibration for Leaf e+ compatibility.
Greentec’s strength lies in sustainable engineering—their 62kWh packs require 30% less energy to produce than new alternatives—while maintaining performance parity with OEM. They offer a 2-year warranty and mobile installation services, making them a convenient choice for owners seeking reliability without dealership prices. Greentec also provides detailed test reports for each pack, verifying SOH and cycle life.
4. CATL (Premium Cell Supplier for Custom/Aftermarket Packs)
CATL— the global leader in EV cell production—supplies high-quality NMC cells for custom and OEM-equivalent 62kWh packs, available through authorized distributors at $11,000-$14,000. Their 4s1p 180Ah NMC cells are the gold standard for Leaf e+ replacements, delivering 1,500+ charge cycles and 70%+ SOH retention after 7 years.
CATL cells are used by top aftermarket brands (including CNS BATTERY) for their superior energy density and thermal stability. While CATL doesn’t sell complete packs directly to consumers, authorized distributors assemble ZE1-optimized 62kWh packs using CATL cells, backed by 3-year warranties. This option is ideal for owners who prioritize cell quality and are willing to work with a trusted distributor for assembly.
Why These Suppliers Outperform Generic Vendors
1. Avoid Low-Quality Generic Risks
Generic 62kWh packs from unvetted suppliers (often priced $5,000-$7,000) use substandard cells and skip ZE1-specific calibration. These packs frequently fail within 6-12 months, causing BMS miscommunication, overheating, or reduced range—costing more in repairs than a quality pack from a top supplier.
2. Ensure Leaf e+ Specific Compatibility
The Leaf e+’s unique thermal cooling channels and BMS protocol demand packs engineered for its platform. Top suppliers like CNS BATTERY and AESC optimize their 62kWh packs for these systems, avoiding premature degradation and ensuring accurate range readings—something generic suppliers rarely deliver.
3. Transparent Warranties & Support
Unlike generic vendors that offer vague or no warranties, the top suppliers provide clear coverage (2-5 years) for defects and premature degradation. They also offer post-installation support, including BMS recalibration and diagnostic checks, eliminating the hassle of troubleshooting on your own.
FAQ About Top Suppliers for Nissan Leaf 62kWh Packs
Are aftermarket 62kWh packs from top suppliers as reliable as OEM?
Yes. OEM-equivalent and remanufactured packs from CNS BATTERY, Greentec Auto, and CATL-authorized distributors match OEM reliability. They use identical cell chemistry and undergo the same testing, with warranties that back their performance.
Will a pack from a non-OEM supplier void my Leaf e+’s warranty?
No. Professional installations with certified packs from top suppliers do not affect warranties on non-battery components (motor, steering). All top suppliers offer their own warranties (2-3 years), adding an extra layer of protection.
How do I verify a supplier’s 62kWh pack quality?
Request third-party test reports, check user reviews (focus on Leaf e+ owners), and confirm ZE1 compatibility. Top suppliers like CNS BATTERY provide these documents upfront, while generic vendors avoid transparency.
Do top suppliers include installation in their pricing?
CNS BATTERY and Greentec Auto include professional installation in package prices, while AESC and CATL distributors may offer it as an add-on ($800-$1,500). All top suppliers use technicians trained on Leaf e+ battery swaps to avoid damage.
