According to an example aspect of the present invention, there is provided a method for determining the state of health of a battery by monitoring charging of the battery over multiple charging instances. The method is implemented within charging stations by, recognizing the battery via a unique identifier; charging the battery; monitoring conditions of the battery during charging, storing data related to the current charging instance based at least partially on the monitored conditions; retrieving data related to at least one earlier charging instance of the uniquely identified battery; and making a determination of the uniquely identified battery's state of health based at least partially on a comparison of the data related to the current charging instance and the retrieved data related to at least one earlier charging instance.
