Frequently Asked Questions

Can you match the exact curvature of my device?

Yes, we can design batteries to match your device's specific radius and arc length, ensuring a perfect fit.

What is the lead time for custom curved batteries?

Typical lead time is 4–6 weeks for prototype and mass production, depending on complexity and volume.

Are curved batteries as safe as flat batteries?

Our curved batteries undergo the same rigorous safety testing as flat cells, including overcharge, short-circuit, and puncture tests.

Can I get samples for testing?

Yes, we provide prototype samples for qualified projects to help you validate performance before full production.
