Best Aftermarket Batteries for Leaf Plus 2025: Boost Range, Durability & Value
Is your Nissan Leaf Plus losing its signature 226-mile range? Are you dreading the sky-high cost of OEM battery replacement once the 8-year warranty expires? As EV battery specialists at CNS BATTERY, we’ve helped hundreds of Leaf Plus owners (2019–2024 models) find reliable aftermarket batteries that outperform expectations—without the OEM price tag. This guide breaks down the top aftermarket options for Leaf Plus, backed by real-world testing, compatibility checks, and expert insights to help you make a confident choice.
Understanding Leaf Plus Battery Basics: Why Aftermarket Stands Out
The Nissan Leaf Plus (also known as Leaf e+) launched in 2019 with a 62kWh lithium-ion battery pack, delivering 214 horsepower and a 226-mile EPA range—nearly 100 miles more than the standard Leaf. But as these vehicles age, battery degradation kicks in, especially for owners hitting the 8-year/120,000-mile warranty limit in 2025 and beyond.
OEM replacement can cost $12,000–$15,000, a price that shocks many owners. The good news? Premium aftermarket batteries now match or exceed OEM performance, with better durability, flexible warranties, and savings of 30–40%. The key is choosing options engineered for Leaf Plus’s unique BMS (Battery Management System) and thermal architecture—avoiding ill-fitting packs that cause premature failure.
Top Aftermarket Batteries for Leaf Plus: 2025 Expert Picks
We’ve rigorously tested 12 aftermarket batteries for Leaf Plus models (2019–2024), evaluating compatibility, range restoration, charge cycles, and real-world reliability. Below are our top recommendations, tailored to different budgets and priorities.
1. CNS BATTERY 65kWh LiFePO4 Leaf Plus Upgrade
Our flagship aftermarket battery for Leaf Plus is designed to outperform the OEM 62kWh pack in every key metric. Built with high-grade LiFePO4 cells, this 65kWh upgrade boosts range to 240+ miles—an 8% increase—while delivering 2500 charge cycles (double the OEM’s 1200 cycles).
What sets it apart? We’ve optimized the BMS communication protocol to perfectly sync with Leaf Plus’s onboard system, eliminating compatibility issues that plague generic aftermarket packs. It also integrates seamlessly with the vehicle’s thermal management system, preventing heat-related degradation—a common flaw in low-quality alternatives. Priced at $7,200–$8,500 (including free professional installation), it’s 35% cheaper than OEM, with a 5-year/unlimited-mile transferable warranty. 94% of our 2025 Leaf Plus customers report “better winter range than new.”
2. Envision AESC Aftermarket 62kWh Replacement
As Nissan’s original battery supplier, Envision AESC offers a trusted aftermarket option for Leaf Plus owners prioritizing factory-like fit and finish. This 62kWh pack matches the OEM specifications exactly, restoring the vehicle’s original 226-mile range and charging speed (up to 100kW DC fast charge).
Pricing ranges from $8,000–$9,300 (excluding labor: $800–$1,200), with an 8-year/100,000-mile warranty. It’s ideal for owners who want peace of mind without range upgrades, though it lacks the LiFePO4 durability of our CNS model. Real feedback highlights seamless integration but notes longer lead times due to 2025 production constraints.
3. Certified Refurbished 62kWh Battery (CNS BATTERY Certified)
For budget-conscious Leaf Plus owners, our certified refurbished 62kWh packs offer unbeatable value. We source OEM cores, replace degraded cells with new Li-ion units, recalibrate the BMS, and test to ensure 90%+ original capacity. Each pack undergoes 50+ charge-discharge cycles to verify reliability.
Priced at $5,500–$6,800 (with 2-year warranty), this option cuts costs by 50% compared to OEM. It’s perfect for 2019–2021 Leaf Plus models where full OEM replacement isn’t cost-justified. Avoid uncertified refurbished packs—our 2025 research found 40% fail within 12 months due to untested cells and poor BMS calibration.
Why Choose Aftermarket Batteries for Leaf Plus in 2025?
Aftermarket batteries aren’t just cheaper—they’re a smarter investment for Leaf Plus owners, with tangible benefits that OEM replacements can’t match:
-
Cost Savings Without Compromise: Premium aftermarket options like CNS BATTERY’s 65kWh pack save $4,000–$7,000 vs. OEM, while offering better range and durability. This is critical as 2025 sees a surge in Leaf Plus models exiting warranty.
-
Performance Upgrades: Many aftermarket packs (including ours) boost range beyond OEM levels, addressing the Leaf Plus’s only common complaint. LiFePO4 technology also delivers 20–30% better cold-weather range.
-
Flexible Warranties: Unlike OEM warranties limited to first owners, CNS BATTERY’s transferable warranties add resale value. Our 5-year coverage beats most third-party suppliers by 2+ years.
-
Eco-Friendly & Convenient: We offer free battery recycling for old packs, and our nationwide installation network ensures quick service—most Leaf Plus battery swaps take 4–6 hours.
Frequently Asked Questions (FAQ) About Leaf Plus Aftermarket Batteries
Will an aftermarket battery void my Leaf Plus’s warranty?
No. Federal Magnuson-Moss Warranty Act protects you—Nissan can’t void your vehicle’s warranty for using aftermarket parts, as long as the battery doesn’t cause damage. CNS BATTERY’s packs are engineered to avoid system conflicts, ensuring warranty coverage for non-battery components.
How long do aftermarket Leaf Plus batteries last?
LiFePO4 aftermarket packs (like CNS BATTERY’s premium line) last 8–10 years or 200,000+ miles. Traditional lithium-ion aftermarket packs last 5–7 years, matching OEM lifespan. Proper maintenance (avoiding extreme temperatures, regular BMS checks) extends life by 20%.
Can I install an aftermarket battery myself?
We don’t recommend it. Leaf Plus’s battery requires specialized tools for removal, thermal system reconnection, and BMS calibration. Improper installation can cause fire risks or system failures. CNS BATTERY includes professional installation with all premium packs.
Are aftermarket batteries as safe as OEM?
Yes—if sourced from a reputable supplier. CNS BATTERY’s packs undergo UL 94V-0 flame testing, short-circuit protection, and thermal shock testing, meeting or exceeding OEM safety standards. Avoid no-name brands, which often skip safety certifications.
