Is your BMW i3 losing range? Discover everything you need to know about battery capacity, degradation, and replacement options in 2026.
The BMW i3 has been a pioneer in the electric vehicle market since its launch. However, like all EVs, battery capacity degradation is a reality that owners must face. If you’re experiencing reduced range or performance issues, this comprehensive guide will help you understand your options.
Understanding BMW i3 Battery Specifications
The BMW i3 comes with different battery configurations depending on the model year:
- 60 Ah (22 kWh) – Early models (2014-2016)
- 94 Ah (33 kWh) – Mid-generation models (2017-2018)
- 120 Ah (42.2 kWh) – Later models (2019-2022)
- New i3 (2022+) – Up to 70.2-79.1 kWh for the Chinese market variant
Understanding your specific battery capacity is the first step in diagnosing performance issues.
Signs Your BMW i3 Battery Needs Replacement
How do you know if it’s time for a battery upgrade? Watch for these critical warning signs:
