Hearing aids have turned into mini-computers. The current hearing technology on the market is processing so much information in the little computers and the amplifiers are driving louder decibels for patients to hear better that it is hard to imagine the hearing aids drain batteries so quickly. But, yes, the average battery typically lasts about a week if the aids are work about 14 hours per day.
Also batteries in the United States have gone through some changes in the last few years. Many of the batteries are mercury free and are now green for the environment. Unfortunately that affect the voltage initially, but the battery manufacturers have recommended new batteries need air/oxygen prior to activation and use. So very important to know that prior to use of each battery, to remove the tab and allow at least one minute of air/oxygen to activate the battery prior to insertion into the hearing device. That has helped battery performance to be more consistent for the most part since the mercury changes.
