Abstract: The present invention relates to a battery dispenser and a cartridge for dispensing batteries to a hearing aid. The battery dispenser comprises a housing having a compartment for accommodation of at least one battery, each battery having an air tab attached to a first surface of the battery, the compartment communicating with the surroundings through a battery outlet formed in the housing, a release member movably attached to the housing, an ejector member adapted for interaction with the release member in such a way that a battery in the housing is ejected through the battery outlet along an ejector axis substantially perpendicular to the first surface upon activation of the release member, and wherein the air tab of the battery is retained in the battery dispenser upon ejection of the battery from the battery dispenser.
