Top Nissan Leaf Battery Suppliers for All Models: Trusted Options for Every Generation
Are you struggling to find a reliable battery supplier for your Nissan Leaf—whether it’s a first-gen 2011 ZE0, a 2018-2023 ZE1, or a 2022 e+ model? With countless suppliers claiming “OEM-quality” batteries, distinguishing between trustworthy providers and risky alternatives is a challenge. The right Nissan Leaf battery supplier can make or break your EV’s performance, lifespan, and safety. As experts at CNS BATTERY, we’ve curated the top suppliers for all Leaf models, breaking down their strengths, compatibility, and value to help you make an informed choice. This guide prioritizes transparency, expertise, and real-world reliability—key to choosing the best battery for your Leaf.
Key Criteria for Evaluating Nissan Leaf Battery Suppliers
Not all suppliers are equipped to serve every Leaf generation. When evaluating options, prioritize these non-negotiable factors to avoid costly mistakes and safety hazards:
• Model Compatibility: Ensure the supplier offers batteries for your specific Leaf generation (ZE0, ZE1) and battery size (24kWh, 30kWh, 40kWh, 62kWh). • Quality Assurance: Look for suppliers with certified testing processes, including state of health (SOH) verification and thermal stability checks. • Warranty Coverage: A reliable supplier backs products with a 1-2 year warranty, covering parts and potential performance issues. • Leaf-Specific Expertise: Avoid generic EV battery suppliers—opt for those specializing in Nissan Leaf systems, including BMS pairing and wiring protocols.
Top Nissan Leaf Battery Suppliers for All Models
Below are the industry’s most trusted suppliers, each catering to different Leaf models, budgets, and performance needs. We’ve highlighted their unique offerings and compatibility to match your vehicle.
1. AESC Group – OEM Supplier for Original Leaf Batteries
AESC Group (formerly Envision AESC) is the founding supplier of Nissan Leaf batteries, dating back to the first-gen 2010 model. With a 20% ownership stake held by Nissan, AESC remains a primary OEM supplier, producing batteries for both ZE0 and ZE1 Leaf models <superscript:1superscript:3. Their manganese-based lithium-ion batteries are known for safety and durability, making them ideal for owners seeking factory-matching parts.
Compatibility: All Leaf generations (24kWh, 30kWh, 40kWh, 62kWh). AESC’s U.S. factories in Kentucky and the Carolinas supply batteries for North American Leaf models, ensuring regional availability <superscript:1. Note that AESC has expanded beyond Nissan to supply other automakers, but their Leaf-specific lines retain OEM specifications.
Pros: OEM authenticity, seamless BMS compatibility, and rigorous quality control. Cons: Premium pricing (40%+ higher than refurbished options) and limited refurbished inventory.
2. CNS BATTERY – Best for Refurbished & Upgraded Batteries
As a leader in Leaf-specific battery solutions, CNS BATTERY stands out for its comprehensive coverage of all Leaf models and cost-effective options. We specialize in certified refurbished batteries—sourced from low-mileage Leafs, reconditioned with genuine Nissan cells, and tested to 90%+ SOH <superscript:5. Our offerings span every battery size, from 24kWh for 2011-2017 ZE0 models to 62kWh for 2022 e+ ZE1 models.
What sets us apart? Every Nissan Leaf battery undergoes a 15-point inspection, including cell balancing, BMS calibration, and thermal testing. We also offer cross-grade upgrades (e.g., 30kWh to 40kWh) for eligible models, backed by a 2-year warranty covering parts and technical support. Our U.S.-based team provides personalized compatibility checks for any Leaf generation.
Pros: Competitive pricing (30-50% less than OEM), model-specific expertise, and 24/7 support. Cons: Refurbished inventory may vary for rare 62kWh packs (we offer pre-order options for high-demand models).
3. LG Energy Solution – Secondary OEM Supplier for Late-Model Leafs
LG Energy Solution became a secondary OEM supplier for Nissan Leaf in 2015, providing batteries for select ZE1 models (2018+) with 40kWh and 62kWh packs <superscript:3. Their lithium-ion polymer batteries offer slightly higher energy density than AESC’s manganese-based cells, making them a popular choice for owners seeking extended range.
Compatibility: ZE1 models (2018-2023) with 40kWh/62kWh batteries. LG’s batteries are fully compatible with Leaf’s BMS but require OEM-specific pairing to avoid fault codes.
Pros: High energy density, reliable performance, and OEM certification. Cons: Limited availability for ZE0 models, and pricing is only marginally lower than AESC.
4. EV Battery Solutions – Regional Expert for Refurbished ZE0 Batteries
EV Battery Solutions specializes in refurbished batteries for first-gen ZE0 Leafs (2011-2017), focusing on 24kWh and 30kWh packs. They source cores from retired fleet vehicles and recondition them with new cells, offering a budget-friendly option for older Leaf owners.
Compatibility: ZE0 models only (24kWh, 30kWh). They provide CAN-bridge adapters for 2011-2012 models, ensuring BMS compatibility. Pros: Low cost ($2,500-$3,500) and fast regional shipping. Cons: No coverage for ZE1 models, and warranty is limited to 1 year.

Frequently Asked Questions (FAQ)
How do I verify if a supplier’s battery fits my Leaf model?
Provide your Leaf’s VIN to the supplier—reputable providers like CNS BATTERY will cross-check it against battery compatibility databases. We also confirm your battery size (via Leaf Spy Pro data, if available) to ensure a perfect fit.
Will a non-OEM supplier’s battery void my Leaf’s warranty?
If your Leaf is still under factory warranty (8 years/100,000 miles for batteries), third-party batteries may void coverage. However, CNS BATTERY’s 2-year warranty provides comparable protection, covering all battery-related issues. For warranty-eligible vehicles, we offer OEM-aligned options to minimize risk.
Are refurbished batteries from trusted suppliers reliable?
Yes—when sourced from suppliers like CNS BATTERY. Our refurbished packs undergo the same testing as OEM units, including cycle life validation and thermal stability checks <superscript:5. They retain 90%+ SOH and last 5-7 years with proper care, matching OEM lifespan at lower cost.
Do suppliers provide installation support?
CNS BATTERY offers 24/7 technical support for DIY installations and partners with a nationwide network of certified technicians for professional service. AESC and LG only provide installation support through Nissan dealerships, while smaller suppliers offer limited guidance.
