A method of charging or recharging a NiMH battery. The disclosure further relates to a charging station and a system. The object of the disclosure is to provide a charging algorithm that charges the battery in a relatively short time and at the same time is relatively gentle as regards its life time degradation. The problem is solved in that the method includes a) providing a constant charge current until a predefined threshold voltage is reached; b) when the predefined threshold voltage is reached, keeping the voltage constant by reducing the charge current; and wherein the predefined threshold voltage is determined depending on the temperature of the battery. This has the advantage of providing a charging algorithm with a compromise between charging speed and battery life time. The disclosure may, e.g., be used for the portable communication devices, e.g. listening devices, such as hearing instruments.
