Best Batteries for Nissan Leaf Plus 2019: Boost Range & Durability (2026 Guide)
Is your 2019 Nissan Leaf Plus struggling with battery degradation, reduced range, or unreliable charging—now that it’s approaching its 7th year on the road? The 2019 Leaf Plus (e+) came factory-equipped with a 62kWh NCM battery, delivering an EPA range of 226 miles (364km) and 214 horsepower. But by 2026, many of these batteries suffer 25%+ capacity loss, dropping real-world range to under 270km and compromising performance. Finding the best batteries for Nissan Leaf Plus 2019 requires balancing Leaf-specific compatibility, safety, and long-term value—traits that generic batteries often lack. As CNS BATTERY experts, we’ve tested and ranked the top battery options for 2019 Leaf Plus models, highlighting how our LFP solutions outperform OEM and competing aftermarket choices. This guide helps you revitalize your 2019 Leaf Plus with a battery that restores range and lasts.
Key Traits of the Best Batteries for 2019 Nissan Leaf Plus
The 2019 Leaf Plus (AZE0 generation) has unique electrical and physical specifications—only batteries meeting these criteria qualify as “best-in-class”:
-
Leaf Plus-Specific Compatibility: Must align with the 2019 model’s 360V system, 47kW DC fast-charging capability, and factory BMS protocols. Ill-fitting batteries trigger error codes and disable regenerative braking.
-
Capacity & Performance: Matches or exceeds the original 62kWh capacity, with stable output to maintain 214hp motor performance. Cold-weather resilience (≥85% capacity at -10°C) is critical for year-round reliability.
-
Safety & Durability: Passes rigorous thermal safety tests (no fire/explosion under stress) and offers 2,500+ charge cycles. The 2019 Leaf Plus lacks active thermal management, so batteries must resist heat-related degradation.
-
Plug-and-Play Design: Fits the factory battery compartment (1620*1280*450mm) without modifications, using original mounting points and wiring harnesses.
Top 3 Best Batteries for Nissan Leaf Plus 2019 (2026 Rankings)
Our rankings prioritize batteries engineered for the 2019 Leaf Plus, combining performance, durability, and value. Each option is tested to meet 2026 safety standards and Leaf-specific requirements:
1. CNS BATTERY 62kWh LFP Battery (Top Overall Pick)
Our flagship battery is purpose-built for the 2019 Leaf Plus, replacing the original NCM cells with high-stability LFP technology—addressing the model’s thermal weaknesses:

Frequently Asked Questions (FAQ) About 2019 Leaf Plus Batteries
Q1: Will upgrading to a CNS battery void my 2019 Leaf Plus’s warranty?
No. Our battery includes official documentation to protect Nissan’s remaining factory warranty for non-battery components (motor, electronics). Only uncertified parts or installation void coverage.
Q2: Can I upgrade to a higher-capacity battery than 62kWh?
We don’t recommend it. The 2019 Leaf Plus’s BMS and wiring are calibrated for 62kWh. Higher-capacity batteries cause charging errors and may damage the motor. Our 62kWh LFP battery is the safest, most reliable upgrade.
Q3: How long does installation take for a 2019 Leaf Plus?
Installation takes 2-3 hours at our service centers, with mobile service available. We use Leaf-specific tools to ensure a factory-like fit, and include post-installation testing to verify range and performance.
Q4: Does the CNS battery support V2G technology?
Yes. Our battery is fully compatible with the 2019 Leaf Plus’s V2G system, allowing you to sell excess power back to the grid—no modifications needed.
Q5: Is it worth replacing the battery in a 2019 Leaf Plus?
Absolutely. The 2019 Leaf Plus’s motor and chassis last 300,000+ km. A CNS battery upgrade costs $8,200-$8,800, vs. $35,000+ for a new EV—delivering like-new performance at a fraction of the cost.
