| Abstract: |
Background: The aim of this study was to evaluate the performance of three disposable hearing aid battery brands available in Wales. Hearing-impaired individuals who utilise hearing aids rely on the functionality of their devices, which is often contingent upon the quality and longevity of disposable batteries. Materials and Methods: A grey literature review foregrounded the battery standards. The “real-life” use of batteries was supplemented through laboratory testing. Parameters relating to performance quality were used to quantify an overall service life of five PR44- and four PR48-size batteries per manufacturer. Results: The literature review signalled a large gap in hearing aid battery consumption research. All battery brands underperformed compared to their specifications but met IEC standards. Conclusions: Revisions to battery consumption test conditions should reflect new technological features and refine expectations of real-life use. It was possible to statistically identify the best performing hearing aid battery brand. |
