Replacing the Battery in 2019 Nissan Leaf Models: Complete Guide & Value Tips
Is your 2019 Nissan Leaf suffering from unexpected range loss, inconsistent charging, or battery warning lights? As part of Nissan’s ZE1 platform, the 2019 Leaf offered two battery options—40kWh (standard) and 62kWh (e+版)—both designed with active thermal management to reduce degradation. Yet, after 7+ years of use, even these advanced packs face capacity loss, with many owners reporting 20-30% diminished range and cold-weather performance drops. Replacing the battery in 2019 Nissan Leaf models is the only way to restore reliability, but navigating OEM costs, compatibility, and aftermarket options can be overwhelming. As CNS BATTERY’s EV experts, we’re breaking down everything you need to know for a seamless, cost-effective battery replacement tailored to your 2019 Leaf.
Key Details About 2019 Nissan Leaf Battery Systems
The 2019 Leaf marked a significant upgrade for Nissan’s EV lineup, with battery technology that addressed earlier generation flaws. Understanding your 2019 model’s battery specs is critical to choosing the right replacement and avoiding compatibility issues.
• 40kWh Standard Model: Delivers 150 EPA miles (241 km) when new, with real-world range of 130-140 miles. Equipped with NMC cells and active thermal cooling, it resists degradation better than Gen 2 Leafs but still loses capacity over time—especially with frequent fast charging. • 62kWh e+ Model: Launched as a limited-edition upgrade (later mass-produced due to high demand), it offers 226 EPA miles (364 km) or 200-230 real-world miles. The larger pack uses optimized cell chemistry and enhanced thermal management, boosting long-distance capability. Both models operate at 394V and require BMS (Battery Management System) recalibration with any battery replacement.
Top Battery Replacement Options for 2019 Nissan Leaf Models
Replacing the battery in 2019 Nissan Leaf models doesn’t mean overpaying for OEM parts. Below are tailored solutions for both 40kWh and 62kWh models, balancing quality, cost, and performance.
1. Remanufactured 40kWh Battery (Best Value for Standard 2019 Leaf)
Priced at $7,500-$8,500 (all-inclusive), our remanufactured 40kWh battery is the top choice for standard 2019 Leaf owners. It saves 35-40% compared to OEM ($12,000-$14,000) while restoring factory range and reliability.
We rebuild these packs using OEM-grade NMC cells, retaining viable components from original AESC modules and replacing worn cells with units optimized for the 2019 Leaf’s thermal system. Each pack undergoes rigorous testing for cell balance, voltage consistency, and thermal stability—critical for avoiding issues like rapid self-discharge or capacity loss. BMS recalibration is included to ensure accurate range readings, and a 2-year warranty covers defects and premature degradation. This option is perfect for daily commuters seeking to extend their 2019 Leaf’s lifespan without breaking the bank.
2. Remanufactured 62kWh Battery (For 2019 Leaf e+ Models)
For 2019 Leaf e+ owners, our remanufactured 62kWh battery ($8,000-$9,500) delivers the same long-distance capability as the original pack at a fraction of OEM cost ($15,000-$17,000). It fits seamlessly into the e+’s battery compartment without modifications, restoring 200-230 real-world miles.
Sourced from CATL (a trusted EV cell supplier), these packs integrate with the e+’s advanced thermal management system to prevent overheating and preserve capacity—even with frequent fast charging. We recalibrate the BMS to sync with the larger pack, retaining fast-charging capability (80% charge in 40 minutes) and NissanConnect features. A 2-year warranty provides peace of mind, making this ideal for e+ owners who prioritize long-range reliability.
3. Certified Used 40kWh/62kWh Battery (Budget Emergency Option)
For 2019 Leaf owners in urgent need of a replacement with minimal upfront cost, certified used batteries ($6,000-$7,000 for 40kWh; $7,500-$8,500 for 62kWh) are a reliable choice. Sourced from low-mileage 2019-2021 Leaf models (30,000 miles or less), these packs undergo 15+ tests to ensure 80%+ state of health (SOH) and no thermal system damage.
Unlike unvetted used batteries (which often suffer from hidden degradation or cell imbalance), our certified options include a 1-year warranty and BMS validation. They’re perfect for secondary vehicles or owners planning to keep their 2019 Leaf for 3-4 more years, delivering immediate reliability at 40% less than OEM. We only source packs from accident-free vehicles, ensuring structural and electrical integrity.
Why Professional Replacement Matters for 2019 Nissan Leaf
The 2019 Leaf’s integrated battery and thermal system demands specialized expertise—DIY or generic shop replacements risk costly mistakes and safety hazards.
Improper installation can damage the thermal cooling lines or misalign the BMS, leading to overheating, battery swelling, or inaccurate range readings—issues that plague owners who opt for unqualified services. Our technicians are trained exclusively on ZE1 platform models, using dedicated tools to remove the battery (180kg for 62kWh packs) safely and recalibrate the BMS to match your replacement pack. We also handle proper battery recycling, complying with environmental regulations and avoiding the risks of improper disposal.
Benefits of Replacing the Battery in 2019 Nissan Leaf Models
1. Restore Factory-Like Range & Reliability
A degraded 2019 Leaf battery may only deliver 80-120 miles (down from 130-230 miles). Our replacement packs restore consistent range, eliminating cold-weather range drops and charging anxiety. You’ll regain the confidence to take weekend trips or daily commutes without monitoring battery levels.
2. Avoid the Cost of a New EV
Replacing the battery costs 15-20% of the price of a new EV ($40,000+), extending your 2019 Leaf’s lifespan by 5-7 years. This is a cost-effective alternative to trading in your vehicle, especially if it’s in good mechanical condition.
3. Preserve Resale Value
A 2019 Leaf with a certified battery replacement retains 15-20% more resale value. Buyers prioritize battery health—our documented replacements make your vehicle far more attractive than one with a degraded or generic battery.
4. Mitigate Fast-Charging Damage
Frequent fast charging accelerates battery degradation in the 2019 Leaf. Our replacement packs use cells optimized for fast charging, reducing future capacity loss and ensuring long-term reliability for high-mileage drivers.
FAQ About Replacing the Battery in 2019 Nissan Leaf Models
Will a battery replacement void my 2019 Leaf’s warranty?
No. Professional replacement with certified packs from CNS BATTERY does not affect warranties on non-battery components (motor, steering). Our packs include their own 1-2 year warranty, adding an extra layer of protection.
Can I upgrade my 2019 40kWh Leaf to a 62kWh battery?
Yes. The 62kWh pack fits the 2019 standard Leaf’s battery compartment, but requires BMS recalibration and minor software updates. This upgrade boosts range by 50%+, turning your standard Leaf into a long-distance capable EV.
How long does battery replacement take for a 2019 Leaf?
Professional installation takes 2-3 hours for both 40kWh and 62kWh models. We complete the process in a single day, minimizing downtime, and include post-installation range testing to ensure optimal performance.
How do I know if my 2019 Leaf needs a battery replacement?
Signs include persistent range loss (20%+ below original), slow charging, battery warning lights, or sudden power drops. Our free diagnostic service can measure SOH and cell balance to confirm if replacement is necessary.
