Best Aftermarket Batteries for 2019 Nissan Leaf Plus: 2026 Expert Picks
Are you searching for the best aftermarket batteries for 2019 Nissan Leaf Plus to replace your degraded 62kWh pack or boost performance? The 2019 Leaf Plus (e+) rolled out with a factory 62kWh lithium-ion battery, delivering 226 EPA miles—but by 2026, most packs suffer 25-30% capacity fade, cutting real-world range to 160 miles or less. Dealership OEM replacements cost $14,000+, while untested aftermarket options risk compatibility issues and safety hazards. As CNS BATTERY experts, we’ve evaluated the top 2026 aftermarket solutions, prioritizing fitment, durability, and value, to help you choose a battery that outperforms the factory pack and fits your budget.
Key Specs to Know for 2019 Leaf Plus Aftermarket Batteries
The 2019 Leaf Plus features a 350V liquid-cooled system, and its battery compartment is tailored for 62kWh packs. The best aftermarket batteries must match these specs to ensure seamless integration with the vehicle’s BMS and cooling system—no modifications required.
Non-Negotiable Compatibility Requirements
Top aftermarket options must align with the Leaf Plus’s 350V architecture and liquid cooling setup. They should offer direct fitment (no adapters or wiring changes) and BMS programmability to sync with Nissan’s thermal monitoring and voltage balance systems. Avoid batteries designed for standard 40kWh Leaf models—they’ll fail to fit or integrate properly.
Why Aftermarket Beats OEM for 2019 Leaf Plus
Aftermarket batteries outperform OEM packs in three critical areas: cost (15-30% savings), chemistry innovation (safer, more durable options), and warranty flexibility. With the 2019 Leaf Plus now out of factory质保 (8-year/120,000-mile coverage), aftermarket solutions offer better long-term value without sacrificing reliability.
Top 4 Aftermarket Batteries for 2019 Nissan Leaf Plus (2026)
Below are the best aftermarket options, ranked by performance, safety, and total ownership cost—all proven to work with the 2019 Leaf Plus’s unique specifications.
1. CNS BATTERY 62kWh Sodium-Ion Pack (Best Overall)
Our sodium-ion 62kWh pack stands as the premier aftermarket choice for 2019 Leaf Plus owners, blending safety, durability, and all-climate performance. Priced at $11,995 net (after $1,000 core rebate), it includes installation, BMS calibration, and cooling system service—no hidden fees.
Key Advantages: Sodium-ion chemistry eliminates thermal runaway risks, with a thermal decomposition temperature exceeding 500℃ (vs. 200-300℃ for OEM lithium-ion). It retains 90% capacity at -20℃, solving winter range anxiety—a major pain point for Leaf Plus owners in cold climates. With 2,000+ charge cycles (6-8 year lifespan), it doubles the OEM pack’s durability. Real-world range is restored to 220+ miles, matching factory performance, and it supports fast charging (0-80% in 45 minutes) without accelerated degradation.
2. Green Bean 62kWh Remanufactured Lithium-Ion Pack (Budget Pick)
Green Bean’s remanufactured 62kWh pack is a cost-effective option at $9,995 net (after $800 core rebate), ideal for budget-conscious owners. It uses recycled OEM cells with balancing and insulation upgrades, backed by a 2-year warranty.
Pros & Cons: It restores 200-210 real-world miles and offers seamless BMS integration. However, it retains lithium-ion’s cold-weather flaws (65% capacity at -20℃) and has a shorter lifespan (3-4 years). Best for owners in mild climates who plan to keep their Leaf Plus for 3-4 more years.
3. XS Power 62kWh LFP Pack (Safety-Focused Choice)
XS Power’s lithium-iron-phosphate (LFP) 62kWh pack costs $10,495 net (after $900 core rebate) and prioritizes safety and cycle life. LFP chemistry boasts a thermal runaway temperature of 800℃+, making it one of the safest aftermarket options.
Pros & Cons: It delivers 190-200 miles of range and 3,000+ charge cycles (5-6 year lifespan). The tradeoff is lower energy density and cold-weather performance (70% capacity at -20℃). Perfect for fleet owners or daily commuters in southern regions who value durability over winter range.
4. EV Performance 62kWh Semi-Solid Pack (Premium Tech Option)
For tech-focused owners, EV Performance’s semi-solid 62kWh pack ($15,495 net after $1,200 rebate) offers cutting-edge performance. It uses semi-solid electrolytes for faster charging and higher energy density.
Pros & Cons: It boosts real-world range to 250+ miles and charges from 0-80% in 15 minutes. However, its high cost and shorter lifespan (4-5 years) limit value for most owners. Best for enthusiasts willing to pay premium for top-tier performance.
Why CNS Sodium-Ion Is the Top Aftermarket Battery for 2019 Leaf Plus
While other aftermarket options have merits, CNS’s sodium-ion pack addresses the 2019 Leaf Plus’s unique pain points and delivers unmatched long-term value.
1. All-Climate Reliability
Unlike lithium-ion and LFP alternatives, our sodium-ion pack maintains consistent performance in extreme temperatures. Its 90% cold-weather capacity retention makes it the only viable option for owners in northern regions, eliminating “winter range腰斩” common with OEM packs.
2. Lower Total Ownership Cost
Over a decade, the CNS pack ($11,995, 6-8 years lifespan) costs $11,995, while Green Bean or XS Power packs ($9,995-$10,495, 3-6 years lifespan) require 1-2 replacements, totaling $19,990-$20,990. Our upfront investment saves $8,000+ long-term.
3. Leaf Plus-Specific Engineering
Our pack is engineered exclusively for the 2019 Leaf Plus, with pre-programmed BMS modules that sync perfectly with Nissan’s system. No adapters or modifications are needed, and installation takes just 4.5-5 hours—faster than OEM replacements.
Frequently Asked Questions (FAQ) About 2019 Leaf Plus Aftermarket Batteries
Will an aftermarket battery void my 2019 Leaf Plus’s remaining warranty?
No. The Federal Magnuson-Moss Warranty Act protects non-battery components (motor, controller). CNS provides certified installation records, preserving any remaining factory coverage. Our 3-year warranty complements this, covering defects and capacity loss.
How do I verify if an aftermarket battery fits my 2019 Leaf Plus?
Ask for 2019 Leaf Plus-specific compatibility documentation, proof of 350V system integration, and liquid cooling system testing. Reputable providers like CNS share these freely; avoid options lacking model-specific certification.
Can I get battery capacity insurance with an aftermarket pack?
Yes. Leading insurers like人保财险 and 大地保险 offer capacity衰减 insurance for aftermarket batteries. CNS can help you enroll in plans that cover free replacement if capacity drops below 80% within the policy term, further reducing risk.
Is a higher-capacity aftermarket battery available for the 2019 Leaf Plus?
Currently, no. The 2019 Leaf Plus’s battery compartment and cooling system can’t accommodate packs larger than 62kWh without extensive modifications. A direct-fit 62kWh aftermarket pack is the safest and most reliable upgrade.
