Nissan Leaf Battery Upgrade Guide for 2019: Boost Range to 385km+
Is your 2019 Nissan Leaf—equipped with the factory 40kWh battery—failing to deliver the range it once did? While the 2019 Leaf marked a significant upgrade from earlier generations with its improved 40kWh pack, years of use, fast charging, and temperature fluctuations can lead to capacity fade and reduced performance. Many 2019 Leaf owners crave the extended range of Nissan’s limited-edition 62kWh battery but are unsure how to safely upgrade. This 2019 Nissan Leaf battery upgrade guide from CNS BATTERY breaks down compatible options, installation essentials, and why our tailored upgrades outperform generic alternatives—helping you revive your 2019 Leaf’s potential.
Key Details of 2019 Nissan Leaf Factory Battery
Understanding the 2019 Leaf’s original battery specs is critical to choosing a compatible, high-performance upgrade. Nissan designed the 2019 model’s battery with incremental improvements over prior generations, but it still has room for enhancement.
OEM 40kWh Battery Specifications & Limitations
The 2019 Leaf’s standard 40kWh lithium-ion battery delivers 241 miles (388 km) of range under EPA testing and 378 km under NEDC standards. It featured upgraded internal wiring and dual sensors for more precise BMS (Battery Management System) control, a step up from older 30kWh packs. However, it lacks advanced active thermal management, making it vulnerable to heat-related degradation. Over time, this can reduce real-world range to 180-200 miles, falling short of modern EV expectations.
2019 Leaf’s Upgrade-Friendly Design
Nissan engineered the 2019 Leaf’s battery compartment to accommodate higher-capacity packs, as seen in the limited-edition 3.Zero e+ model with a 62kWh battery. This means upgrades don’t require chassis modifications—critical for safety and compliance. The 2019 Leaf’s BMS is also calibrated to work with higher-capacity packs, simplifying integration with minimal software adjustments.
Top Battery Upgrade Options for 2019 Nissan Leaf
CNS BATTERY offers two primary upgrade paths for 2019 Leaf models, balancing range needs, budget, and OEM-level compatibility. Both options use premium cells and pre-calibrated BMS to ensure seamless performance.
62kWh Upgrade: Maximum Range for Long Trips
Our 62kWh upgrade mirrors the limited-edition 3.Zero e+ model’s performance, boosting WLTP range to 239 miles (385 km)—a 62-mile (100 km) increase over the factory 40kWh pack. We use high-energy-density NMC cells with active thermal management, addressing the 2019 Leaf’s factory thermal limitation. This upgrade is ideal for owners who frequently take long trips or want to eliminate range anxiety, supporting fast DC charging to 80% capacity in 40 minutes.
50kWh Upgrade: Balanced Performance & Value
For owners seeking a middle ground between range and cost, our 50kWh upgrade delivers 290 km (180 miles) of real-world range—20% more than the factory 40kWh pack. It uses the same high-quality cells as our 62kWh option but with a smaller capacity, making it more affordable. The plug-and-play design integrates instantly with the 2019 Leaf’s BMS, requiring no software hacks, and retains all factory charging capabilities.
Step-by-Step 2019 Nissan Leaf Battery Upgrade Process
Upgrading your 2019 Leaf’s battery is straightforward with CNS BATTERY’s pre-calibrated packs, but proper installation is key to safety and performance.
Pre-Upgrade Prep & Safety
Start by parking on a flat surface, turning off all electronics, and disconnecting the 12V battery under the hood. Remove the high-voltage service plug near the driver’s seat and wait 15 minutes to discharge residual voltage—essential for avoiding electrical shocks. Gather insulated tools, a hydraulic jack, jack stands, a multimeter, and an electrical fire extinguisher for safety.
Removing the Factory 40kWh Pack
Secure the vehicle with jack stands, then remove the underfloor battery cover using an insulated screwdriver. Disconnect the wiring harnesses and high-voltage cables, labeling each connection to avoid confusion. The 40kWh pack weighs ~140kg, so use a battery lift or helper to lower it safely. Inspect the battery compartment for corrosion or damage before installing the new pack.
Installing & Calibrating the Upgrade Pack
Lift the CNS BATTERY pack into position, aligning it with the 2019 Leaf’s mounting bolts. Tighten bolts to 35-40 Nm, then reconnect the cables per your labels. Our packs are pre-calibrated to sync with the 2019 Leaf’s BMS, so no dealer resets are needed. Reinstall the high-voltage service plug and 12V battery, then let the system idle for 10 minutes to complete calibration.
Post-Upgrade Testing
Verify voltage with a multimeter, then take a test drive to confirm range readouts, acceleration, and charging functionality. You’ll notice immediate improvements in range consistency and charging speed, with the BMS accurately displaying remaining power.
Why CNS BATTERY’s 2019 Leaf Upgrades Stand Out
A 2019 Nissan Leaf battery upgrade is only as good as the battery and support behind it. Our solutions are engineered exclusively for 2019 models, delivering unmatched quality and reliability.
OEM-Matching Compatibility & Performance
Our 62kWh and 50kWh packs match the 2019 Leaf’s exact dimensions, voltage (360V), and BMS parameters. We replicate the limited-edition 3.Zero e+’s performance without compromising factory functionality, ensuring all safety features and charging systems work seamlessly.
Enhanced Thermal & Safety Protections
Unlike the factory 40kWh pack, our upgrades include active thermal management to protect cells in extreme temperatures. Each pack undergoes 100+ hours of testing, including thermal shock trials and short-circuit simulations, meeting IEC 62133 and UN38.3 safety standards.
Cost Savings vs. OEM & New EVs
Nissan’s OEM 62kWh battery (for limited editions) costs $8,000+ , while our 62kWh upgrade starts at $5,800—25% savings with identical performance. Upgrading your 2019 Leaf also avoids the $35,000+ cost of a new EV, extending its lifespan by 5-7 years.
Benefits of Upgrading Your 2019 Nissan Leaf Battery
Upgrading your 2019 Leaf’s battery transforms its usability, offering value that goes beyond extended range.
Eliminate Long-Distance Range Anxiety
With a 62kWh upgrade, you can tackle weekend getaways and long commutes without frequent charging stops—matching the range of newer EV models. Fast charging support ensures you’re back on the road quickly, even on busy trips.
Boost Resale Value
2019 Leaf models with a 62kWh battery upgrade command 15-20% higher resale values. Potential buyers prioritize extended range, and our certified upgrades make your vehicle more attractive than those with worn factory packs.
Reduce Long-Term Ownership Costs
Worn batteries lead to inefficient charging and increased reliance on public chargers (2-3x more expensive than home charging). Our upgrades restore charging efficiency, cutting monthly costs by 30-40% and minimizing maintenance needs.
Frequently Asked Questions (FAQ) About 2019 Leaf Battery Upgrades
Will upgrading my 2019 Leaf’s battery void the warranty?
