Ultimate Guide to BMW i3 EV Battery Range Performance – Must Read
Understanding Your BMW i3 Battery Performance
The BMW i3 has established itself as a pioneering electric vehicle in the luxury segment. For 2026, BMW has optimized the i3’s battery system, delivering up to 625 kilometers of CLTC range with battery capacities ranging from 70.2 to 79.1 kWh. However, as your i3 ages, battery degradation becomes a real concern that impacts daily driving experience.
At CNS BATTERY, we specialize in BMW i3 battery replacement and upgrade solutions that restore your vehicle’s original performance—and potentially exceed it.
