Revive Your EV: Premium Nissan Leaf & BMW i3 Battery Solutions

Is your Nissan Leaf or BMW i3 struggling with reduced range? Are you facing the sticker shock of a dealership replacement? You’re not alone.

The CNS BATTERY Advantage: More Than Just Cells

What sets us apart from generic aftermarket brands or risky refurbished batteries? It’s our commitment to quality and customer care.

1. Premium CATL Cells vs. The Competition
We refuse to cut corners. While many competitors reuse discarded or degraded cells, CNS BATTERY utilizes brand-new, original CATL cells. This guarantees top-tier performance, thermal stability, and a lifespan that far exceeds refurbished alternatives.

2. Industry-Leading Warranty
We stand by our products. That’s why we offer an unbeatable 2-year / 80,000 km warranty (whichever comes first). This comprehensive coverage includes protection against defects in materials and workmanship, as well as prorated coverage for performance degradation (ensuring at least 70% capacity). This warranty is significantly longer than the industry standard, reflecting our confidence in our quality.

Switching batteries can be daunting, but you’re never alone. We provide:

  • Free Pre-Sales Compatibility Checks: Upload your VIN, and we confirm the perfect fit before you buy.
