FAQ for Wearable Health Monitor & Hearing Aid Batteries

A: We specialize in extreme miniaturization, producing coin cells with diameters as small as [e.g., 6mm] and custom free-form shapes to fit the most compact devices.

A: Safety is paramount. We use a combination of stable cell chemistry, multi-layered internal safety features, a reliable protection circuit, and can work with biocompatible external materials. All designs are rigorously tested to meet standards like IEC 62133.

A: Due to the high degree of custom engineering and validation, our MOQ for a new design in this category typically starts at 50,000 to 100,000] units.

A: Our batteries are engineered for a long service life, typically designed to retain high capacity after 500-1000+ charge cycles, which covers several years of daily use.

Can you support wireless charging?

  • A: Yes, absolutely. We can design the battery and its protection circuit to be fully compatible with wireless charging standards like Qi, which is common for hearing aids and other sealed wearable devices.

A: Given the precision required, the lead time for the first batch of functional prototypes is generally 6-8 weeks after design finalization.

A: We focus on two key areas: maximizing the cell’s energy density (mAh per volume) and designing the integrated protection circuit for ultra-low quiescent current (power consumption in standby).

A: We provide a full documentation package, including detailed specifications, manufacturing quality data, and all safety certifications (IEC 62133, UN38.3, etc.) to support your technical file for regulatory bodies.

A: Yes, this is our core strength. We excel at creating free-form, custom-shaped batteries that maximize the use of every cubic millimeter within your device’s unique industrial design.

A: Please provide a 3D model of the available space, the target capacity (mAh), voltage (3.7V), charging/discharging current requirements, and your estimated annual volume.
