Revitalize Your BMW i3: The Budget-Friendly Battery Upgrade That Delivers 60% More Range
Is your once-reliable BMW i3 now struggling to make it through your daily commute? You’re not alone. Many BMW i3 owners face the frustrating reality: after 5-7 years of ownership, their battery’s range has dwindled from 180km to a mere 80km, turning what was once a practical city car into a frustrating daily chore.
The BMW i3 Battery Dilemma: Pay or Replace?
When your BMW i3 battery starts losing capacity, you’re often faced with a painful choice: pay $12,000+ for an OEM replacement from the dealership or consider a costly alternative. The reality? Most BMW dealerships charge over $10,000 for a battery replacement that’s essentially the same as what you could get for half the price from a reputable aftermarket supplier.
The truth is simple: BMW’s official battery replacement program is designed to maximize profit, not customer satisfaction. But what if you could get the same quality, better range, and a 2-year warranty for less than half the price?
Why CNS BATTERY Is the Smart Choice for BMW i3 Owners
CNS BATTERY isn’t just another battery supplier. We’ve spent years perfecting our BMW i3 battery solutions to deliver genuine value without compromising on quality.
Premium Quality, Not Compromised Performance
Unlike competitors who use recycled or refurbished cells, we exclusively use brand new CATL ternary lithium cells – the same high-quality cells used by leading EV manufacturers worldwide. This means:
- Longer lifespan: Our batteries are engineered to outlast OEM replacements
- Consistent performance: No unexpected drops in range or power
- True capacity: Your 45kWh battery delivers 45kWh, not 35kWh like some competitors
Real Range, Real Results
After installing our 45kWh battery in her 2017 BMW i3, Lisa K. from Berlin shared her experience: “After the original battery degraded, the 4S dealership quoted €12,000 for a replacement. My friend recommended CNS, so I decided to give them a try. Unexpectedly, the brand-new CATL battery cells were of the same quality as the original. Now, the full charge range has increased from the original 180km to 290km, and I only need to charge it once a week for daily commuting.”
This isn’t an isolated case. Our customers consistently report 60% more range compared to their degraded OEM batteries.

But don’t worry if you’re not a mechanic: Our technical team provides remote video guidance within hours, as demonstrated in this customer’s experience: “When I encountered wiring connection problems during installation, I contacted customer service, and they arranged remote video guidance within an hour.”
Global Shipping Made Simple
We ship worldwide with:
- Fumigation-free wooden packaging to protect your battery during transit
- Multiple shipping options: Sea shipping (4-8 weeks) or express services (3-8 business days)
- Free shipping to mainland China for customers with shipping agents
“Sea shipping took 6 weeks, and the packaging was a fumigation-free wooden crate, so the battery arrived without any damage,” shared Lisa K.
