Standard zinc hearing aid batteries are not rechargeable, according to the Liberty Hearing Centers website. However, some manufacturers do make hearing aid batteries compatible with rechargeable USB components.
Standard hearing aid batteries can last anywhere between three and nine hours; larger batteries tend to last longer than smaller ones, states Liberty Hearing. For patients not wanting to deal with the hassle of changing batteries, surgically implanted devices are available that perform the same duties without the maintenance of traditional hearing aids. With the proper care, a hearing aid should last for four to six years, according to Liberty Hearing Center.
