Each option uses brand-new ternary lithium cells from CATL, ensuring consistent performance and longevity that refurbished batteries simply cannot match.
Why Choose CNS BATTERY for Your BMW i3?
Premium Cell Quality You Can Trust
Not all replacement batteries are created equal. CNS BATTERY distinguishes itself through:
✓ Brand-New CATL Cells
Unlike refurbished options that recycle aged battery cells, CNS uses exclusively new CATL ternary lithium cells – manufactured by China’s largest and most reputable battery producer. This means no hidden degradation, no surprise failures, and consistent performance from day one.
✓ Extended Warranty Protection
Every CNS battery comes with a 2-year or 80,000-kilometer warranty, whichever comes first. This coverage significantly exceeds industry standards and provides genuine peace of mind for your investment.
✓ Plug-and-Play Installation
For complete battery packs, installation is straightforward – simply connect and go. For module-level purchases, you’ll need to connect 6 power lines and 1 signal line, with comprehensive video tutorials and remote engineering support available throughout the process.
Real Owner Experience: Lisa’s BMW i3 Transformation
“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. When I encountered wiring connection problems during installation, I contacted customer service, and they arranged remote video guidance within an hour. Now, the full charge range has increased from the original 180km to 290km.”

Lisa’s experience reflects what hundreds of CNS customers report: dramatic range restoration, professional support, and exceptional value.
The Hidden Costs of Cheap Battery Solutions
Why Refurbished Batteries Fall Short
Many owners initially gravitate toward refurbished batteries due to lower upfront costs. However, this approach often leads to:
- Premature Failure: Recycled cells degrade faster, sometimes within 6-12 months
- No Reliable Warranty: Most refurbishers offer minimal or non-transferable coverage
- Swelling Risks: Aged cells are prone to expansion, creating safety hazards
- Inconsistent Performance: Range varies significantly and declines rapidly
One UK owner shared: “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.”
The OEM Premium Problem
Dealership replacements guarantee compatibility but come with substantial drawbacks:
- Excessive Pricing: Often 2x the cost of quality aftermarket options
- Limited Innovation: No capacity upgrade options – you get exactly what you had before
- Brand Premium: You’re paying for the logo, not necessarily superior technology
