BMW i3 Battery Upgrade: Maximize Range, Slash Costs, and Enjoy Peace of Mind

Why Your BMW i3’s Battery Needs an Upgrade Now

Is your BMW i3’s range shrinking faster than you can say “electric driving”? Do you find yourself planning trips around charging stations instead of enjoying the open road? If you’re tired of your i3’s battery degrading to 180km max range after just 5 years, you’re not alone. Many BMW i3 owners face this frustrating reality, often paying $12,000+ for an OEM replacement that’s simply too expensive for what it delivers.

The Real BMW i3 Battery Solution You’ve Been Waiting For

CNS BATTERY has revolutionized the BMW i3 battery replacement market with genuine, high-performance alternatives that outperform OEM batteries while saving you 50%+ on costs. We don’t just offer batteries—we deliver real range improvements, extended battery life, and hassle-free installation for your BMW i3.

Why CNS BATTERY Stands Out in the BMW i3 Market

Unlike other “battery” suppliers that resell refurbished or aged cells, we provide brand-new CATL lithium cells—the same quality used in original BMW i3 batteries. Our 45kWh, 50kWh, and 62kWh battery packs are engineered for seamless integration with your BMW i3’s system, ensuring:

• Perfect compatibility with all BMW i3 models (2013-2023)
• Plug-and-play installation for complete battery packs
• 2-year/80,000km warranty (longer than most OEM warranties)
• Real-world range improvements (from 180km to 290km+)
• No modifications needed to your vehicle

The CNS BATTERY Advantage: What Makes Us Different

Real BMW i3 Owners’ Success Stories

“After the original battery degraded, the 4S dealership quoted €12,000. I chose CNS, and the new battery with CATL cells was the same quality as original. The range increased from 180km to 290km, and the sea shipping took 6 weeks. The fumigation-free wooden crate ensured no damage. The lifetime technical support was incredible—I even got a customized winter charging guide!”
— Lisa K., Berlin, Germany

“I replaced my BMW i3 battery with CNS’ 45kWh option. The installation was straightforward, and the full charge now provides 290km range. The customer service provided remote video guidance within an hour when I had wiring questions. The value for money is incredible!”
— David L., London, UK

Why Choose CNS for Your BMW i3 Battery Replacement?

1. Genuine CATL Battery Cells, Not Refurbished Junk

We use brand-new CATL ternary lithium cells, the same cells BMW uses in their original batteries. This means you get the same performance, safety, and longevity without the premium price tag.

2. 2-Year/80,000km Warranty That Actually Covers You

Most “aftermarket” batteries offer short warranties with loopholes. Our warranty is clear, comprehensive, and covers the performance you expect. If your battery drops below 9 bars (out of 12) within 2 years or 80,000km, we’ll replace it.

3. Simple Installation with Full Support

For complete battery packs, installation is plug-and-play—no modifications needed. For battery modules, we provide detailed video guides showing exactly how to connect the 6 power lines and 1 signal line. Our technical team is available for remote guidance via video call if you need help.

4. Worldwide Shipping with Robust Packaging

We ship worldwide using fumigation-free wooden packaging that protects your battery during transit. Ocean shipping takes 4-8 weeks (standard), with express options available for urgent needs.
