Abstract

A method for monitoring charge level or remaining capacity of a battery pack, a disposable battery or a rechargeable battery, which is used to supply energy for an automation technology, field device having a data storage unit associated with the battery pack, disposable battery or rechargeable battery. Specific information about the battery pack, disposable battery or rechargeable battery is stored in the data storage unit and process-specific and operation-specific information about energy consumption is written to the data storage unit. In the case of the battery pack, disposable battery or rechargeable battery being used in a second automation technology field device, remaining service life of the battery pack, the disposable battery or the rechargeable battery is calculated and output on the basis of the process- and operation-specific information.
