Nissan Leaf 62kWh Battery Specs and Upgrades: 2026 Expert Guide
Are you looking to understand the Nissan Leaf 62kWh battery’s technical specs or seeking reliable upgrades for your Leaf e+ (2019-2022)? The 62kWh battery marked Nissan’s biggest leap in Leaf performance, delivering a 239-mile WLTP range and 340N·m of torque—transforming the Leaf from a commuter EV to a long-distance contender. Yet, many owners struggle to find clear specs or trustworthyNissan Leaf 62kWh battery upgrades, as generic solutions fail to match its advanced liquid cooling system and NCM cell architecture. At CNS BATTERY, we specialize in 62kWh battery specs analysis and upgrades, leveraging 2026’s latest battery technology to enhance performance and durability. This guide breaks down critical specs, compatible upgrades, and why we’re the trusted choice for your Leaf’s battery needs.
Key Specs of the Nissan Leaf 62kWh Battery
The Nissan Leaf 62kWh battery (found in Leaf e+ models) is a third-generation NCM (Nickel-Cobalt-Manganese) pack, engineered for balance, range, and reliability. Understanding its core specs helps you evaluate upgrades and maintain optimal performance.
1. Core Technical Specifications
The battery features 192 prismatic NCM cells arranged in 24 modules, operating at a 360V high-voltage system. It boasts an energy density of 207 Wh/kg—10% higher than the 40kWh Leaf battery—enabling a 239-mile WLTP range (385km) and 150-mile EPA range. The pack weighs 518 lbs (235kg) and fits seamlessly into the Leaf e+’s chassis without compromising interior space.
Charging capabilities include CHAdeMO fast charging, which takes 30 minutes to reach 30-80% capacity with a 50kW charger. The battery’s discharge rate supports a 160kW motor, delivering instant torque for responsive driving. A sophisticated liquid cooling loop maintains cell temperatures between 25-35℃, critical for preserving NCM cell life and performance.
2. Durability and Degradation Metrics
Nissan rates the 62kWh battery to retain 70% of its capacity after 8 years or 100,000 miles under normal use. However, real-world data shows degradation varies by climate—cold weather and frequent fast charging can reduce capacity to 60% in 6-7 years. The battery’s BMS (Battery Management System) continuously monitors cell voltage balance (target variance ≤0.05V) and temperature, triggering protective measures to prevent overcharging or overheating.
Top Nissan Leaf 62kWh Battery Upgrades for 2026
We’ve developed three tailored upgrades for the Leaf 62kWh battery, combining 2026’s advanced battery technology with Leaf-specific compatibility. Each upgrade addresses common pain points like cold-weather range loss and limited lifespan.
1. 62kWh Sodium-Lithium Hybrid Battery – Enhanced Durability & Cold Performance
Our sodium-lithium hybrid upgrade retains the 62kWh capacity while boosting durability and low-temperature performance. Leveraging 2026’s material advancements, this pack uses abundant sodium to reduce reliance on cobalt, cutting production costs by 30% vs. virgin NCM. It delivers 12,000+ charge cycles—equivalent to 27 years of use at 450 charges annually—far exceeding the original battery’s lifespan.
Priced at $8,995 (all-inclusive), it offers 90% capacity retention at -20℃ (vs. 85% for OEM) and integrates seamlessly with the Leaf e+’s liquid cooling system. The pack includes a 3-year/50,000-mile warranty, covering capacity fade and thermal issues—ideal for northern owners seeking long-term reliability.
2. 70kWh LFP Upgrade – Range Boost & Safety
For owners craving more range, our 70kWh LFP (Lithium-Iron Phosphate) upgrade delivers a 26% range increase (239 miles to 301 miles WLTP). Cobalt-free LFP cells eliminate ethical mining concerns and offer 3,000+ charge cycles, with a 10-year lifespan at 80% capacity retention. The pack’s thermal stability prevents thermal runaway, even in extreme conditions.
At $10,495 all-inclusive, it’s 40% cheaper than OEM 70kWh upgrades (if available). We optimize the Leaf e+’s liquid cooling system and reflash the BMS to support the larger pack, ensuring seamless integration. This upgrade is perfect for frequent road trippers wanting to maximize their Leaf’s potential.
3. 62kWh Recycled-Core NCM Battery – Budget-Friendly Replacement
Our recycled-core 62kWh NCM battery is the affordable option for owners needing a direct replacement. Using 60% recycled materials from end-of-life EV batteries (refined to OEM-grade standards), it matches the original’s specs—239-mile range, 30-minute fast charging, and liquid cooling compatibility.
Priced at $7,495 all-inclusive (50% cheaper than OEM), it undergoes rigorous testing for voltage balance and thermal stability. Backed by a 2-year/30,000-mile warranty, it’s ideal for budget-conscious owners looking to restore their Leaf e+ to factory performance without overpaying.
Why OEM 62kWh Upgrades Fall Short vs. CNS BATTERY Solutions
OEM 62kWh battery replacements cost $14,000-$15,500 and use outdated NCM technology, offering no improvements over the original pack. They also lack 2026’s durability enhancements, with the same 8-year lifespan and cold-weather limitations.
Our upgrades outperform OEM in three key areas: longer lifespan (up to 27 years vs. 8 years), better cold-weather performance (90% vs. 85% capacity retention at -20℃), and lower cost (40-50% savings). We also include Leaf-specific BMS calibration and cooling system optimization—services OEM charges extra for, if available.
Benefits of Nissan Leaf 62kWh Battery Upgrades
A quality 62kWh battery upgrade transforms your Leaf e+, delivering value that extends beyond upfront costs.
Extended Range & Daily Usability
Upgrades restore or exceed the original 239-mile range, eliminating range anxiety. The 70kWh LFP option lets you tackle cross-state trips without frequent charging, while the sodium-lithium pack ensures reliable winter performance.
Maximized Vehicle Lifespan
The Leaf e+’s chassis and motor are built for 150,000+ miles—our long-lifespan upgrades extend its usable life by 10+ years, avoiding the $30,000+ cost of a new EV.
Improved Resale Value
A Leaf e+ with an upgraded 62kWh battery sells for 40% more than one with a degraded OEM pack. Buyers prioritize battery health and advanced technology, making upgrades a smart investment.
Frequently Asked Questions (FAQ) About Leaf 62kWh Battery Specs & Upgrades
Will a 62kWh battery upgrade void my Leaf e+’s warranty?
No. Our certified upgrades and professional installation preserve your Leaf’s non-battery warranty (motor, controller, etc.). We provide detailed service records to Nissan, ensuring coverage remains intact for all unaffected components.
Can I upgrade a 40kWh Leaf to 62kWh?
Yes. We offer 62kWh upgrades for 2018-2022 40kWh Leafs (ZE1 generation). The upgrade includes a new battery pack, liquid cooling system optimization, and BMS reflash—delivering a 59% range boost (151 miles to 239 miles).
Do upgrades affect fast-charging performance?
No—our upgrades maintain or improve fast-charging capabilities. The sodium-lithium and recycled-core packs match the OEM’s 30-minute 30-80% charge time, while the 70kWh LFP pack only adds 5 minutes (35 total) due to 2026’s fast-charge optimized cells.
How long does a 62kWh battery upgrade take?
Standard upgrades take 4-6 hours, with most vehicles ready the same day. If cooling system maintenance is needed (e.g., coolant replacement), we complete it during the same visit at a discounted rate.
