The utility model discloses a zinc air button battery for a specific hearing aid, which comprises a positive pole shell, a negative pole cover is arranged in the positive pole shell, a sealing ring is arranged in the positive pole shell, and the negative pole cover, the sealing ring and the top end of the positive pole shell are all conical. According to the technical scheme, the zinc air button battery can be better and tightly matched with a specific hearing aid battery bin, the zinc air button battery can be kept stable and is not prone to loosening or falling off in the using process, the stability ensures that the hearing aid can continuously and stably work, the problem that the tone quality is reduced or interrupted due to battery loosening is solved, and the hearing aid is more stable in use. Meanwhile, a tight sealing structure can be formed between the battery negative electrode cover and the battery bin, so that electrolyte leakage is effectively prevented, the hearing aid is protected from being damaged by the electrolyte through the sealing performance, the safety of a user is ensured, and potential risks caused by electrolyte leakage are avoided.

A state of health of a battery cell used in a hearing instrument is ascertained. For each of a plurality of charging cycles, a battery manager of the hearing instrument ascertains a charge transferred to the battery cell and a number of charging characteristic values that provides information about the change in a state of charge of the battery cell brought about by the charge. Based on the transferred charge and the charging characteristic values a capacity characteristic value is ascertained that forms a characteristic variable for a present charging capability of the battery cell. A signal processor averages respective capacity characteristic values of at least some past charging cycles at a specific time and calculates an averaged charging capacity. The averaged charging capacity is compared with a reference value representing an original capacity of the battery cell to determine the state of health of the battery cell.
