BMW i3 94Ah to 120Ah Upgrade Review: Unleashing More Range, Power, and Value
Introduction: Is Your BMW i3 Battery Holding You Back?
You love your BMW i3 for its eco-friendly drive, compact design, and urban agility. But after a few years, you’ve noticed a frustrating drop in range—especially when using air conditioning or climbing hills.
- Original 94Ah battery: Once offered ~180km of real-world range.
- Now: Down to 120–140km per charge.
What if you could upgrade to a 120Ah battery for less than half the cost of BMW’s official replacement?
In this honest, data-backed review, I’ll explain why the CNS Battery 120Ah upgrade is the smartest, most cost-effective way to restore—and even boost—your BMW i3’s performance.
Why Upgrade from 94Ah to 120Ah? The Real-World Benefits
1. More Range, Fewer Charging Stops
A 120Ah battery increases your i3’s usable capacity from 33kWh to 42kWh, delivering:
- ~220–240km of range (EPA-estimated 440km full charge).
- 30%+ more driving per charge—perfect for road trips or longer commutes.
2. Future-Proof Your EV
BMW no longer sells new 94Ah batteries, forcing owners into:
- Refurbished OEM batteries (prone to failure).
- Overpriced aftermarket options with poor warranties.
The CNS Battery 120Ah uses brand-new CATL cells (the same supplier as Tesla and BMW’s latest models), ensuring long-term reliability.
3. Save Thousands vs. OEM Replacement
BMW’s official 120Ah replacement costs $16,000+—but CNS Battery offers:
- 7,800–9,500 (depending on specs).
- 24-month/80,000km warranty (vs. BMW’s 12-month coverage).
- Free compatibility check & installation support.
