Easy Install Nissan Leaf Plus EV Battery vs AESC: Which Powers Your Drive Better?
Is Your Nissan Leaf Losing Its Electric Spark?
Does your Nissan Leaf Plus feel like it’s running on empty before you even reach your destination? You’re not alone. Thousands of Leaf owners face the frustrating reality of battery degradation – watching their once-reliable electric companion struggle with shrinking range, slower charging, and unpredictable performance.
When replacement time comes, two names dominate the conversation: CNS BATTERY and AESC. But which one truly delivers the power, reliability, and value your Leaf deserves? This comprehensive comparison cuts through the marketing noise to help you make an informed decision that could save you thousands while restoring your vehicle’s original performance.
Understanding the Battery Replacement Landscape
The Nissan Leaf Plus Battery Challenge
The Nissan Leaf Plus (also known as Leaf e+) launched with a 62kWh battery pack, promising up to 364 kilometers of range. However, like all lithium-ion batteries, capacity naturally declines over time. Many owners report significant degradation after 5-7 years, with range dropping by 30-40%.
When facing replacement, you typically have three options:
- Original AESC battery – The factory-installed brand
- Refurbished batteries – Recycled cells with uncertain history
- Aftermarket premium alternatives – Like CNS BATTERY with new CATL cells
Who Is AESC?
AESC (Automotive Energy Supply Corporation) is the original battery supplier for Nissan Leaf vehicles. Founded as a joint venture between Nissan and NEC, AESC has been the go-to source for OEM Leaf batteries since the model’s inception. While they offer genuine compatibility, their pricing and warranty terms often leave owners searching for better alternatives.
Head-to-Head Comparison: CNS BATTERY vs AESC
Battery Cell Quality
CNS BATTERY utilizes brand-new CATL battery cells – manufactured by China’s largest and most respected battery producer. CATL ranks among the global top three battery manufacturers, supplying premium automotive brands worldwide. Every cell undergoes rigorous quality testing before assembly.
AESC provides original factory cells, which guarantee compatibility but don’t necessarily offer technological advantages over newer alternatives. Their cells meet OEM standards but come at a significant price premium.
Winner: CNS BATTERY – New CATL cells deliver superior performance at a fraction of the cost.
Price Comparison
Here’s where the difference becomes stark:
| Feature | CNS BATTERY | AESC Original |
|---|---|---|
| 62kWh Pack Price | ~$7,800-$8,200 | ~$15,000-$16,000 |
| Cost Savings | 50%+ less | Full retail price |
| Installation Support | Free video guidance | Dealer fees apply |
| Shipping | DDP included | Varies by region |
CNS BATTERY offers original equipment manufacturer (OEM) compatible solutions at approximately 50% of the AESC price. For Leaf owners, this translates to savings of $7,000-$8,000 without compromising quality.
Warranty Coverage
CNS BATTERY provides an unbeatable 2-year/80,000 km warranty – far surpassing standard industry offerings. This comprehensive policy covers:
- Defects in materials and workmanship
- Free replacement or repair options
- Prorated coverage for performance degradation
- Minimum 70% capacity guarantee over warranty period
AESC warranties vary by region and dealer, typically offering shorter coverage periods with more restrictions. Many owners report challenges when claiming warranty service through official channels.
Winner: CNS BATTERY – Longer warranty with clearer terms and easier claims process.
Installation Experience
One of CNS BATTERY’s standout features is the easy install design. The company provides:
- Step-by-step installation videos in high definition
- Free video call guidance via Zoom or Line
- Color-coded connectors matching original factory parts
- Plug-and-play compatibility requiring no modifications
- Complete installation toolkit including insulated gloves and terminal cleaner
Most installations complete within 1-2 hours. Professional technicians can finish in approximately 50 minutes, while DIY enthusiasts typically need 2 hours following the detailed video tutorials.
AESC batteries require dealer installation in most cases, adding £800-$1,200 in labor costs and scheduling delays.
Winner: CNS BATTERY – Flexible installation options with comprehensive support.
Real-World Performance
Customer reviews reveal compelling performance data:
Mark T. from California upgraded his 2015 Leaf ZE0 from 40kWh to 62kWh with CNS BATTERY:

David L. from London shared his experience:
“The full charge range is 440km, consistent with the specifications, and the charging speed is the same as the original. It feels like my car has been revived!”
Javier R. from Paris noted cold weather performance:
“After replacing it with a CNS 68kWh battery, the full charge now provides 470km of range, and even in cold winter conditions, it maintains around 400km.”
These testimonials demonstrate CNS BATTERY’s ability to deliver consistent range, reliable charging speeds, and stable performance across various climates and conditions.
