Abstract: The disclosure presents a method and a hearing aid with an improved method for updating a discharge charging profile of a battery. The method comprises following steps; receiving during a first discharge step of the plurality of discharge steps a first primary battery voltage from a voltage monitor unit, receiving during the first discharge step a first primary charge from a charge monitor unit or a storing unit, determining a first secondary charge, where the first secondary charge is one or more discharge steps lower than the first primary charge, determining a first secondary battery voltage difference to be equal to a secondary battery voltage difference of a plurality of secondary battery voltage differences relative to the first secondary charge, wherein the plurality of secondary battery voltage differences is stored in the storing unit, determining a first secondary battery voltage to be equal to a secondary battery voltage of the plurality of secondary battery voltages relative to the first secondary charge, determining a first primary battery voltage difference between the first secondary battery voltage and the first primary battery voltage, determining a new battery voltage difference based on a first weight of the first primary battery voltage difference and a second weight of the first secondary battery voltage difference, and updating the discharge battery profile with the new battery voltage difference.

Abstract: A method for charging a battery of a hearing instrument is disclosed. The method may comprise obtaining (110) a discharge function as a relationship between a battery charge and a voltage of the battery. The method may further comprise obtaining (112) a desired runtime capacity to be achieved by charging the battery. The method may further comprise determining (114) a charging voltage taking into account at least the discharge function and/or the desired runtime capacity. The method may further comprise charging (116) the battery with the determined charging voltage. The method may improve battery longevity while at the same time ensuring that a desired runtime capacity is provided. Furthermore, a charging system (200) for charging a battery of a hearing instrument and a computer program product are disclosed.
