Nissan Leaf Battery: Complete Guide
The Nissan Leaf battery is all-new for 2026, built on the CMF-EV platform it shares with the Nissan Ariya. In the U.S. it comes with a 75 kWh battery that travels up to 303 miles. A smaller 52 kWh version is sold in Europe and is expected to join the U.S. lineup later as the base model. Both options use liquid cooling to keep the battery at a safe temperature.
The car charges quickly using DC fast charging. The 75 kWh battery reaches a peak of 150 kW, while the 52 kWh battery reaches 105 kW. Both models can charge from 10% to 80% in about 35 minutes.
This is the first Leaf to use the North American Charging Standard (NACS), which replaces the older CHAdeMO plug. Every car comes with two ports: a J1772 port for home charging and a NACS port for fast charging on the road. Nissan launched this third-generation model in the U.S. in fall 2025.
Quick answer
The Nissan Leaf battery is a lithium-ion pack. Sizes run from 24 kWh in the 2011 original to 75 kWh in the 2026 model. Older Leafs cool the pack with air alone and lose capacity faster in hot weather. The 2026 Leaf switches to liquid cooling, NMC chemistry, and up to 303 miles of range.
Key figures: 24 / 30 / 40 / 62 kWh (2011–2025) · 75 kWh (2026) · Most packs keep 70–85% at 100,000 miles · Replacement about $5,500–$9,500 fitted · Warranty 8 years / 100,000 miles

Nissan Leaf Battery Sizes: Every Generation (2011–2026)
The Leaf has used five battery sizes in 15 years. Every one is a lithium-ion pack, but the chemistry, cooling, and range changed a lot along the way. This table is the fastest way to identify what is in any used Leaf.
| Battery | Years | EPA range | Chemistry | Cooling |
|---|---|---|---|---|
| 24 kWh | 2011–2015 | 73–84 miles | LMO (manganese-based) | Air (passive) |
| 30 kWh | 2016–2017 | 107 miles | LMO/NMC blend | Air (passive) |
| 40 kWh | 2018–2025 | 149–151 miles | NMC | Air (passive) |
| 62 kWh (Leaf Plus) | 2019–2025 | 212–226 miles | NMC | Air (passive) |
| 75 kWh | 2026– | 259–303 miles | NMC | Liquid (active) |
Two things stand out. First, no Leaf has ever used an LFP battery — even the cheapest versions stayed with nickel-based or manganese-based cells. Second, every Leaf before 2026 cooled its battery with air alone, which is why battery life on the older cars varies so much.
The Biggest Upgrade in Leaf History
The 2026 Nissan Leaf offers major improvements over the 2025 model. While the older Leaf Plus had a 62 kWh battery and could travel up to 226 miles, the new model goes 77 miles further. Nissan also upgraded the charging system. The 2026 Leaf now uses the NACS charging plug and charges twice as fast as before.
The most important upgrade is the new liquid-cooled battery, which replaces the older air-cooled design. The previous air-cooled battery often lost health in hot weather or when charged quickly too many times. Liquid cooling keeps the battery at a safe temperature, which makes the new car much more reliable.
Liquid Cooling: The Critical Fix
The 2026 Leaf now includes active liquid thermal management. This feature helps the car stay competitive, as other brands have used it for years. Coolant flows through the battery pack to keep the cells at the best temperature. This process stops the battery from getting too hot during summer heat. It also helps the car charge quickly even after repeated fast charging.
This cooling system also saves waste heat from the motor and the onboard charger. It moves this heat to warm the battery in cold weather. You can use the MyNISSAN app to warm up your battery before you stop to charge. This prepares the battery for better performance.
NACS: Native Supercharger Access After 15 Years of CHAdeMO
The original Leaf used CHAdeMO — the Japanese DC charging standard that has become increasingly marginalised in North America and Europe. The 2026 Leaf abandons CHAdeMO entirely in favour of native NACS. This gives direct access to Tesla’s 20,000+ Supercharger network in the U.S. and Canada without an adapter. A dual-port setup keeps SAE J1772 for AC charging. This charging infrastructure improvement alone resolves one of the biggest ownership friction points from every previous Leaf generation.
2026 Leaf Charging Speeds
| Method | Power | 52 kWh Leaf | 75 kWh Leaf |
|---|---|---|---|
| Level 1 (120V) | ~1.4 kW | ~40 hours full | ~60 hours full |
| Level 2 (7.2 kW AC) | 7.2 kW | ~8 hours full | ~12 hours full |
| DC Fast | 105 / 150 kW | ~35 min (10–80%) | ~35 min (10–80%) |
Crossover Body: A New Direction
The 2026 Leaf moves from hatchback to compact crossover body — higher ride height, more ground clearance, and a larger interior. This body change aligned the Leaf with where the compact car segment has shifted. The drag coefficient is 0.26 Cd — efficient for a crossover body. The CMF-EV platform is the same architecture as the Nissan Ariya — meaning the Leaf benefits from the Ariya’s proven EV platform engineering at a significantly lower price point.
Battery Warranty
Nissan covers the 2026 Leaf battery with an 8-year / 100,000-mile warranty — and specifically guarantees capacity retention of at least 9 bars of the 12-bar capacity gauge within this period. This specific retention guarantee is more prescriptive than most competitors’ simple “70% capacity” promises. The liquid cooling significantly reduces the degradation risk that plagued earlier air-cooled Leaf batteries in hot climates.
How Long Does a Nissan Leaf Battery Last?
Most Leaf batteries last 8 to 15 years. Owner and fleet data shows most packs still hold about 70–85% of their original capacity at 100,000 miles. The dashboard shows this as capacity bars: a healthy battery displays 12 bars, and every lost bar means real range is gone.
Heat is the Leaf’s weak point. Every Leaf before 2026 cools its pack with air, not liquid. In hot states like Arizona, early 24 kWh packs lost 20–30% of their capacity in about eight years, and some lost more than 35%. The 40 kWh and 62 kWh packs age more slowly, and the liquid-cooled 2026 pack should age slowest of all.
If you are shopping for a used Leaf, check the bars before anything else, and read our guide to Nissan Leaf battery degradation and the worst models to avoid. A cheap Leaf showing 8 bars can still be a good city car — or a bad buy at the wrong price.
Nissan Leaf Battery Replacement Cost
A replacement Leaf battery typically costs $5,500 to $9,500 fitted, depending on the pack size and whether the pack is new, used, or refurbished. Smaller 24 kWh packs sit at the low end when a good used unit is available. The larger 62 kWh packs sit at the top.
Nissan’s own warranty replacements are 40 kWh packs, even when the failed battery was smaller. Third-party specialists can also fit a bigger used pack into an older Leaf, which is the cheapest way to give a 24 kWh car modern range.

Frequently Asked Questions
What type of battery does the Nissan Leaf use?
Every Nissan Leaf uses a lithium-ion battery. The first cars (2011–2015) used a manganese-based LMO chemistry, later cars moved to an NMC blend, and the 2026 Leaf uses liquid-cooled NMC cells. No Leaf has ever used an LFP battery.
What battery sizes does the Nissan Leaf come in?
Five sizes: 24 kWh (2011–2015), 30 kWh (2016–2017), 40 kWh (2018–2025), 62 kWh in the Leaf Plus (2019–2025), and 75 kWh in the 2026 Leaf. A smaller 52 kWh version of the new Leaf is sold in Europe.
How long does a Nissan Leaf battery last?
Most Leaf batteries last 8 to 15 years, and most still hold 70–85% of their capacity at 100,000 miles. Early air-cooled packs in hot climates age fastest. The liquid-cooled 2026 battery should last longest of all.
How much does a Nissan Leaf battery replacement cost?
Typically $5,500 to $9,500 fitted, depending on pack size and whether the replacement is new, used, or refurbished. Warranty replacements fitted by Nissan are 40 kWh packs.
Does the 2026 Nissan Leaf have an LFP battery?
No. The 2026 Leaf uses an NMC lithium-ion battery with liquid cooling. Nissan has not announced an LFP version of the Leaf for any market.
What is the range of the 2026 Nissan Leaf?
Up to 303 miles (EPA) for the S+, 288 miles for the SV+, and 259 miles for the Platinum+. All three trims use the same 75 kWh battery — the range changes with weight and wheel size.
Conclusion
The Nissan Leaf battery is the biggest upgrade in the car’s 15-year history. This new 75 kWh liquid-cooled battery pack solves the main problems of older models. A liquid-cooled battery uses fluid to keep the battery at the right temperature, which helps it last longer. This new version offers 303 miles of range and fast 150 kW NACS charging. Nissan also added a heat pump and V2L, which lets the car power electronic devices.
Nissan priced this model from $29,990, the lowest starting price of any new EV on sale in the U.S. That undercuts rivals like the Chevrolet Equinox EV. If you want Nissan’s bigger crossover instead, read our Nissan Ariya battery guide.
