Client Background
The client produces modern rechargeable hearing aid systems, combining small in-ear devices with desktop or pocket charging cases.
Their products target users transitioning away from disposable button cells toward more convenient rechargeable solutions.
Challenges
The client needed a robust energy solution for the charging case and associated accessories:
• Sufficient capacity to support multiple full hearing-aid recharge cycles between mains charges.
• Reliable performance over thousands of daily charge and discharge events.
• Compact pack dimensions compatible with slim charging-case designs.
• Pressure from distributors and end users to reduce waste from single-use cells while maintaining safety.
Battery Solution
HIMAX ELECTRONICS provided NiMH cells in AA format, with capacities ranging from 300mAh to 2700mAh at 1.2 V, for use in charging bases and related accessories.
The NiMH chemistry was chosen for its robustness, tolerance to frequent cycling, and established safety profile in consumer devices.
Pack designs were created using selected AA NiMH cells in series and/or parallel, depending on the output voltage and capacity required by the client’s systems.
HIMAX optimized cell selection and matching to ensure consistent behavior across packs and stable performance over the product lifetime.
Testing & Compliance
The NiMH solutions were tested for:
• Electrical performance and cycle life under repeated daily charge-and-discharge patterns typical of hearing-aid charging cases.
• Temperature rise during charging and discharging in confined housings.
• Safety and reliability per the client’s internal standards for medical-adjacent consumer devices. Documentation was provided to help the client prepare product safety files and user guidance.
Results & Performance
With HIMAX NiMH solutions, the client’s charging cases delivered predictable numbers of recharges for hearing aids before needing to be plugged in again.
The energy system showed stable performance over long-term use, with low failure rates and minimal capacity loss in typical service life.
Customer Benefits
End users enjoyed the convenience of rechargeable systems and reduced dependence on disposable button cells, aligning with environmental expectations.
The client strengthened its product offering with a reliable, well-supported power platform and reduced after-sales issues related to charging performance.
