BMW i3 Battery Replacement: Save 50% Without Sacrificing Range or Reliability
Is Your BMW i3’s Battery Draining Your Budget and Driving Experience?
You’ve invested in a sleek, efficient BMW i3, but now your battery’s range has dropped from 180km to just 120km. The dealership quotes you $12,000 for a replacement, while your daily commute demands more. You’re not alone. Over 60% of BMW i3 owners face this exact dilemma. But what if you could get a high-performance battery that delivers 290km of range for less than half the price of the original manufacturer option?
Why OEM Battery Replacements Don’t Have to Break the Bank
CNS Battery has transformed the BMW i3 battery market by offering genuine OEM-compatible solutions that match factory specifications without the premium price tag. Unlike other aftermarket options that use recycled or refurbished cells, CNS uses brand new CATL ternary lithium cells – the same cells used by leading EV manufacturers worldwide.
Our battery solutions for the BMW i3 are available in 45kWh, 50kWh, and 62kWh configurations, designed specifically for your vehicle’s exact model year and battery management system. Each battery pack undergoes rigorous quality testing to ensure it meets or exceeds OEM performance standards.
The CNS Advantage: Quality You Can Trust
Why BMW i3 Owners Choose CNS Battery

Real BMW i3 Owners, Real Results
“After the original battery degraded, the 4S dealership quoted €12,000 for a replacement. I chose CNS, and the brand-new CATL battery cells were of the same quality as the original. The full charge range increased from 180km to 290km, and I only need to charge it once a week for daily commuting.” – Lisa K., Berlin, Germany
“I was worried about the installation, but the video tutorial was incredibly detailed. The wiring was straightforward with color-coded connectors. The range increased from 120km to 290km, and the battery capacity remains at 11/12 bars after 10 months of use.” – Mark T., California, USA
