Best Aftermarket Nissan Leaf Batteries for 2019: Top Picks for Range & Reliability
Is your 2019 Nissan Leaf’s 40kWh battery losing range, or are you looking to upgrade to long-distance capability without buying a new EV? The 2019 Leaf—part of the ZE1 generation—rolled off the line with either a 40kWh standard battery (226 miles EPA range) or a 62kWh e+ variant (241 miles EPA range). As these batteries age, 2019 Leaf owners face a choice: overpay for OEM replacements or choose aftermarket options that balance quality, cost, and performance. As CNS BATTERY’s EV specialists, we’re breaking down the best aftermarket Nissan Leaf batteries for 2019, helping you avoid generic duds and invest in a solution that revitalizes your EV.
Key Considerations for 2019 Nissan Leaf Aftermarket Batteries
The 2019 Leaf features advanced NCM (nickel-cobalt-manganese) cell chemistry and a sophisticated BMS (Battery Management System), so not all aftermarket batteries are compatible. Prioritize these factors to ensure a seamless fit and performance:
-
ZE1 Platform Compatibility: The 2019 Leaf’s integrated battery-chassis design requires batteries that match OEM dimensions and mounting points—avoid one-size-fits-all packs.
-
Cell Chemistry Match: NCM cells (not LFP) are required to maintain the 2019 Leaf’s charging speed and thermal performance.
-
BMS Calibration Support: Aftermarket batteries must sync with the 2019 Leaf’s BMS to avoid “ghost range” and charging failures.
-
Warranty Coverage: Reputable aftermarket batteries include 3+ year warranties, protecting against capacity loss and defects.
Top 3 Aftermarket Nissan Leaf Batteries for 2019
We’ve curated the best aftermarket options for 2019 Leaf owners, each tailored to different needs—from budget-friendly replacements to long-range upgrades.
1. CNS BATTERY OEM-Grade 40kWh Refurbished Battery (Best Value)
For 2019 Leaf owners seeking to restore factory performance at a fraction of OEM cost, our refurbished 40kWh battery is the top choice. Priced at $3,899 (all-inclusive), it costs 45% less than Nissan’s $7,299 OEM replacement while delivering 85%+ original capacity.
Each pack undergoes a rigorous 12-point inspection: faulty cells are replaced with NCM cells matching the 2019 Leaf’s factory specs, modules are rebalanced, and the battery is tested for thermal stability (-20°C to 60°C). It integrates seamlessly with the 2019 Leaf’s BMS and retains fast-charging capability (80% charge in 30 minutes), just like the original battery.
Backed by a 3-year/50,000-mile warranty, this battery is ideal for daily commuters who want reliable performance without overspending. Real-world range hits 190-210 miles in mild weather—nearly matching the 2019 Leaf’s original EPA rating.
2. CNS BATTERY 62kWh Upgrade Battery (Long-Range Transformation)
For 2019 Leaf owners wanting to upgrade from the 40kWh to 62kWh capacity (like the factory e+ model), our aftermarket 62kWh battery is a game-changer. Priced at $8,999, it’s 25% cheaper than Nissan’s $12,000 OEM 62kWh pack and delivers a 55% capacity boost.
This battery uses high-energy-density NCM cells (200 Wh/kg) to push real-world range to 220-235 miles—perfect for road trips and eliminating range anxiety. It maintains the 2019 Leaf’s V2G (Vehicle-to-Grid) capability and integrates with existing fast-charging systems, charging to 80% in just 30 minutes.
The 62kWh upgrade also enhances performance, with smoother acceleration and better hill-climbing power—mirroring the factory e+ model’s 214 horsepower output. It’s backed by a 5-year/100,000-mile warranty, matching OEM protection.
3. Premium NCM 40kWh New Aftermarket Battery (Maximum Durability)
For owners wanting like-new performance without OEM pricing, our new 40kWh aftermarket battery ($5,499) is the answer. Built with brand-new NCM cells and OEM-compatible components, it delivers 95%+ original capacity and a 4-year/75,000-mile warranty.
This battery includes enhanced thermal management—critical for 2019 Leaf owners in extreme climates—reducing range loss in hot or cold weather by 10-15%. It’s pre-calibrated for the 2019 Leaf’s BMS, ensuring accurate range readouts and consistent charging from day one.
It’s an excellent choice for owners planning to keep their 2019 Leaf for 5+ years, as it retains 80% capacity after 1,000 charge cycles (8-10 years of daily use).
Why Generic Aftermarket Batteries Fail for 2019 Leafs
Cheap generic batteries ($2,500-$3,500) may seem appealing, but they’re risky for the 2019 Leaf. Here’s why they underperform:
1. Compatibility Issues
Generic packs often use mismatched cell chemistries or incorrect dimensions, leading to poor fit, BMS conflicts, and charging failures. Many can’t support the 2019 Leaf’s V2G technology or fast-charging speeds.
2. Lack of Testing
Unlike our batteries, generic options skip thermal and charge-discharge testing. This leads to premature degradation—most fail within 1-2 years, requiring costly replacements.
3. No Warranty or Support
Generic batteries typically come with 30-90 day warranties (if any) and no technical support. If the battery fails, owners are left with no recourse.
Benefits of Choosing the Right Aftermarket Battery for 2019 Leaf
Investing in a quality aftermarket battery delivers long-term value beyond upfront cost:
1. Cost Savings vs. OEM & New EVs
Our 40kWh refurbished battery saves $3,400 vs. OEM, while the 62kWh upgrade costs 77% less than buying a new 2024 Leaf e+ ($38,500).
2. Restored Resale Value
A 2019 Leaf with a quality aftermarket battery sells for 15-25% more than one with a degraded or generic battery—helping you recoup upgrade costs.
3. Environmental Sustainability
Refurbished batteries keep old cells out of landfills, reducing your carbon footprint—aligning with the 2019 Leaf’s eco-friendly design.
FAQ About Aftermarket Nissan Leaf Batteries for 2019
Will an aftermarket battery void my 2019 Leaf’s warranty?
If your 2019 Leaf is still under Nissan’s 8-year/100,000-mile battery warranty, unauthorized replacements may void coverage. Our batteries use OEM-compatible components and comply with Nissan standards, and our warranty seamlessly takes over once factory coverage expires.
Can I install an aftermarket battery myself?
We don’t recommend DIY installation for the 2019 Leaf. Its integrated battery-chassis design and high-voltage systems require specialized tools and ZE1-specific expertise. Improper installation can cause electrical shock, fire, or BMS damage—costing more to fix than professional service.
Will an aftermarket battery affect my 2019 Leaf’s charging speed?
No—our aftermarket batteries retain the 2019 Leaf’s original charging speeds. The 40kWh and 62kWh options charge to 80% in 30 minutes via fast charger, same as factory batteries. Generic batteries may slow charging due to poor cell quality.
Is the 62kWh upgrade worth it for a 2019 Leaf?
Yes—if you take frequent road trips or struggle with range anxiety. The upgrade boosts range by 55%, making the 2019 Leaf a long-distance capable EV. It’s also a cost-effective alternative to trading in for a newer model.
