Frequently Asked Questions (FAQ)

1. Are CNS batteries compatible with my specific Nissan or BMW model?
Yes. CNS batteries are designed to OEM standards, ensuring compatibility with voltage, capacity, and interface matching (such as Type 2 connectors). To be 100% certain, simply provide our customer service team with your vehicle’s year, model number, and VIN code for instant confirmation.

2. How much can I save compared to buying from a dealer?
You can save 50% or more. For example, replacing a degraded battery in a Nissan Leaf can cost over $16,000 at a dealership. With CNS, the same 62kWh solution can cost approximately half that amount, offering incredible value for money without compromising on the quality of brand-new CATL cells.

3. Is the installation difficult?
Installation typically takes 1-2 hours. We provide comprehensive installation guides, including high-definition tutorial videos and downloadable PDFs. For the BMW i3 and Nissan Leaf models, the process is often plug-and-play. However, we recommend having it installed by a certified technician to avoid warranty issues, though DIY is certainly possible with basic tools.

4. What payment and delivery methods do you offer?
We offer various secure payment options. For delivery, we provide DDP (Delivered Duty Paid) service to most countries, meaning we handle all shipping, customs duties, and clearance. We ship globally via partners like DHL, FedEx, and UPS, adhering to strict IATA dangerous goods regulations for lithium batteries.

5. What if I encounter a problem after purchase?
Our commitment extends beyond the sale. We offer a 24/7 technical support hotline and lifetime technical support. If you encounter a BMS programming issue or have maintenance questions, our team is ready to assist, often resolving issues within 24 hours.
