The term identifies the maximum capacity of the power source used in a specific bone conduction hearing device model. Understanding this characteristic is essential because it directly influences the device’s operational lifespan between charges. For example, a power source rated at 300 milliampere-hours (mAh) would generally allow for longer continuous use than one rated at 200 mAh, assuming similar usage patterns.
Knowing the upper limit of a power source’s capacity is critical for users seeking extended functionality. It allows for better planning of usage, especially during activities where recharging opportunities are limited. Historically, improvements in power source technology have led to smaller, more efficient devices with longer battery lives, significantly enhancing the user experience.
