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.
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.
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.
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.
本研究旨在评估威尔士现有的三个一次性助听器电池品牌的性能。使用助听器的听力受损者依赖于其设备的功能，而这通常取决于一次性电池的质量和使用寿命。
一项灰色文献综述突出了电池标准。通过实验室测试补充了电池的“实际使用”情况。与性能质量相关的参数用于量化每个制造商的五节PR44尺寸和四节PR48尺寸电池的总体使用寿命。
文献综述表明助听器电池消耗研究存在很大差距。所有电池品牌的实际表现均低于其规格，但符合IEC标准。
电池消耗测试条件的修订应反映新技术特征并完善对实际使用的预期。从统计学上识别出性能最佳的助听器电池品牌是有可能的。
