Stop Swollen Modules! Upgrade Your Nissan Leaf to 40kWh Today
If you are driving a Nissan Leaf and notice your battery performance dropping significantly or your modules physically swelling, it is time for a definitive solution. Many owners face the frustrating reality of degraded second-hand or refurbished batteries failing prematurely. At CNS BATTERY, we offer a superior alternative: a brand-new 40kWh lithium battery pack designed to stop the cycle of failure and restore your vehicle to peak performance.
Why Refurbished Batteries Fail (And Why New Matters)
The Nissan Leaf has been a pioneer in the EV market, but its early battery technology has limitations. Many owners attempt to save money by purchasing used or refurbished packs, only to face “swollen modules” within months.
The Problem with Old Tech:
Refurbished batteries often consist of salvaged cells that have already undergone significant chemical degradation. When these aged cells are forced to charge and discharge, the internal pressure builds up, leading to physical swelling. This not only damages the Battery Management System (BMS) but also creates safety hazards.
The CNS Solution:
We do not rebuild old junk. CNS BATTERY manufactures brand-new 40kWh lithium battery packs using fresh, high-grade cells sourced directly from CATL (Contemporary Amperex Technology Co. Limited), the world’s largest lithium-ion battery manufacturer. By utilizing brand-new chemistry, we eliminate the risk of swelling from day one.
The 40kWh Advantage: Reliability Meets Range
Our 40kWh upgrade is not just about fixing a broken battery; it is about optimizing your driving experience.
- Zero Swelling Guarantee: Constructed with new materials and advanced engineering, our packs maintain structural integrity under extreme conditions.
- Extended Range: Experience a full charge range of approximately 245km (depending on driving conditions), revitalizing your daily commute.

Real Stories: Owners Who Stopped the Swelling
David L. (London, UK)
“Previously, I tried to save money by replacing my battery with a refurbished one, but it swelled up after only six months, and the range dropped drastically. I was considering buying a new car, but a friend… told me to try CNS BATTERY. After listening to my friend’s advice and replacing my battery with a 40kWh/62kWh CNS battery, I realized the difference that brand-new CATL battery cells make! The full charge range is consistent with the specifications… Most importantly, the price was only $8200, saving me nearly $10,000 compared to the original manufacturer’s price. The 2-year warranty also provides peace of mind. I highly recommend it!”
