For BMW i3 owners in 2026, battery degradation isn’t just inevitable—it’s expensive. The original 94Ah battery, once capable of 114 miles, now struggles to hit 80 miles after 7–8 years. Dealerships exploit this, charging 300% markups for “official” replacements that often use recycled cells with shortened lifespans.
But here’s the 2026 game-changer: Aftermarket batteries now outperform OEM options in range, durability, and cost.
At CNS Battery, we’ve engineered a 120Ah battery pack (built with brand-new CATL cells, the same supplier as Tesla) for $5,899—including free installation support and a 24-month warranty.

2026’s Best BMW i3 Battery Deals: Why Smart Drivers Choose Aftermarket
1. The $16,000 Rip-Off: What Dealerships Won’t Tell You
Dealerships claim their “refurbished” batteries are “as good as new.” But the truth is:
- Recycled cells (often from crashed EVs) with degraded performance.
- No thermal management (risk of overheating).
- 12-month warranty (half of CNS Battery’s coverage).
“I bought BMW’s $16,000 battery. It failed after 10 months. Never again.”
—Emily S., California
