Is Your BMW i3 Losing Range? Here’s the Smart Solution You Need
Does your BMW i3 feel like it’s running on empty before you even reach your destination? You’re not alone. Thousands of BMW i3 owners worldwide are facing the same frustrating reality: battery degradation that turns their once-reliable electric vehicle into a range-anxiety nightmare.
The dealership tells you a replacement will cost $16,000 or more. That’s nearly the value of your entire car! But what if there’s a smarter way to restore your i3’s performance without breaking the bank?
Why BMW i3 Owners Are Choosing Aftermarket Battery Solutions
The truth is, original manufacturer batteries come with a hefty price tag that doesn’t always match the value you receive. Smart BMW i3 owners are discovering that high-quality aftermarket batteries offer the same performance at a fraction of the cost.
At CNS BATTERY, we specialize in BMW i3 battery replacement and upgrade solutions that deliver exceptional value without compromising on quality or safety.
Available BMW i3 Battery Options
| Battery Capacity | Range After Installation | Best For |
|---|---|---|
| 45kWh | 300+ km | Daily commuting |
| 50kWh | 350+ km | Extended city driving |
| 62kWh | 430+ km | Long-distance travel |
All batteries feature brand-new CATL ternary lithium cells – the same premium technology used by leading electric vehicle manufacturers worldwide.

Our batteries are designed for long-term durability with stable performance far exceeding refurbished alternatives. With proper care, you can expect many years of reliable service backed by our 2-year/80,000 km warranty.
Can I install the battery myself?
Yes! If you have basic mechanical skills and tools, our video tutorials make installation straightforward. For complete battery packs, it’s truly plug-and-play. For modules, you’ll need to connect 6 power lines and 1 signal line. If you’re not confident, we recommend professional installation or purchasing the complete pack.
What if I have problems after installation?
Contact our support team immediately. If your product is under warranty, we provide free replacement parts or accessories. Our engineers offer remote video support to diagnose and resolve issues quickly.
Are the battery cells really new?
Absolutely. We use brand-new CATL ternary lithium cells, not refurbished or recycled components. This is a key differentiator from many competitors who sell repaired batteries with degraded cells.
Can I cancel my order?
Orders can be cancelled within 24 hours for a full refund. After 24 hours, refunds are evaluated based on production progress. Once shipped, orders cannot be cancelled.
What’s covered under warranty?
The warranty covers manufacturing defects and capacity retention (12 bars should not drop below 9 bars after full charge within 2 years/80,000 km). The warranty is non-transferable and applies only to the original purchaser. Improper installation voids the warranty.
