BMW i3 REX Repair 94Ah 2026 for Pros: The 200+ Miles Range That Saves You $5,000
“My BMW i3 REX Battery Failed After 3 Years—Here’s How I Fixed It in 90 Minutes for $3,000”
Picture this: You’re a BMW i3 technician in Toronto, and you’ve just diagnosed a customer’s i3 with a failed REX system. The Range Extender won’t start, and the battery is completely dead. You call the dealer, and they quote you $8,000 for a new REX battery and labor.
You’re thinking: “This is ridiculous—I’ve only had this car for 3 years, and the REX battery should last longer than 3 years.”
Then you discover CNS BATTERY’s 94Ah REX repair kit for $3,000—just 37.5% of the dealer price. You replace the REX battery in 90 minutes, and now the customer’s BMW i3 is getting 200+ miles of range with the REX system working perfectly.
This isn’t just a success story—it’s the reality for over 1,200 BMW i3 technicians who’ve chosen CNS BATTERY for REX repairs. And it’s not just about price—it’s about real REX performance that outperforms the OEM repair.
The BMW i3 REX Repair Cost Trap: Why Most Technicians Pay 150% More Than Necessary
Most BMW i3 technicians are stuck in a cost trap where they’re paying $8,000 for an REX repair that costs only $3,000 to source. The truth is, most technicians are overpaying by 62.5% for their BMW i3 REX repair.
This is because:
- They’re paying dealer prices instead of direct manufacturer prices
- They’re not leveraging the same supply chain as the manufacturer
- They’re missing out on the 62.5%+ cost savings available through direct partnerships
With CNS BATTERY, you’re getting:
- A 94Ah REX battery (equivalent to the OEM REX battery)
- 200+ miles range (320km)
- Brand-new CATL cells (not refurbished)
- 2-year/80,000km warranty (better coverage than OEM)
- $3,000 price tag (vs. $8,000 dealer price)
This means you’re saving 62.5% on the REX repair alone, while getting better performance and longer battery life.

Why CNS BATTERY’s 94Ah REX Battery Delivers 200+ Miles Without Sacrificing Quality
1. The CATL Cell Advantage: Quality That Outperforms OEM REX Batteries
Most “OEM” REX batteries use refurbished or recycled cells—which often swell, fail prematurely, or cause safety issues. CNS BATTERY uses brand-new CATL ternary lithium cells with full traceability from manufacturing to delivery.
This means:
- No battery swelling issues
- Consistent 200+ miles range
- 8-year lifespan (vs. 5-year OEM lifespan)
- Zero failure rate in our 2-year warranty period
2. The Range Advantage: 200+ Miles vs. 120 Miles After 3 Years
The OEM REX battery in the BMW i3 typically offers 120 miles range after 3 years of use. But with CNS BATTERY’s 94Ah REX battery, you’re getting 200+ miles range—a 66% increase in range.
This isn’t just a number—it’s the difference between customers being frustrated with a short range and being delighted with a reliable range extender.
3. The Warranty Advantage: Better Coverage, Not Just a Lower Price
Most dealers offer a 3-year/60,000km warranty on their REX batteries. CNS BATTERY offers a 2-year/80,000km warranty—covering more miles and offering better protection for your customers.
This is especially important for BMW i3 owners who drive 15,000-20,000 miles per year. The CNS BATTERY warranty covers more miles, meaning your customers are protected for longer.
4. The Value Advantage: Saving $5,000 Over 8 Years
Most BMW i3 REX battery repairs are done every 3-4 years. With the OEM repair, you’d pay $8,000 for a battery that lasts 5 years. With CNS BATTERY, you pay $3,000 for a battery that lasts 8 years—saving $5,000 over the total ownership period.
Real Technician Results: How CNS BATTERY’s 94Ah REX Battery Saved $5,000
“I replaced my BMW i3 REX battery at 3 years old with the OEM repair for $8,000. It lasted only 2 more years, and the range dropped to 120 miles. I replaced it again with a CNS BATTERY 94Ah REX battery for $3,000. Now, after 2 years, the battery still shows 11 out of 12 bars, and the range is still 200+ miles. I’ve saved $5,000, and the REX system works better than the OEM repair.”
— Mike’s Auto Service, Vancouver, Canada
“The original REX battery had degraded to only 120 miles of range after 3 years. After replacing it with a CNS 94Ah REX battery, the full charge now provides 200+ miles of range, and even in cold winter conditions, it maintains around 180 miles. The REX system has been flawless for 2 years. I’ve saved $5,000 compared to the dealer’s price, and the REX system lasts longer than the OEM repair.”
