The invention relates to a method for dispensing a lubricant (3) in a metered manner by means of a lubricant dispenser which comprises a lubricant cartridge (2) filled with lubricant (3) at least one electrochemical gas generating cell (4) and on control electronics (1) for controlling the gas generating cell (4). The control electronics (1) comprise a microcontroller (8) and a switch (9) for interrupting the current flowing through the gas generating cell (4). At adjustable time intervals the circuit through the gas generating cell (4) is closed by the control electronics (1) and lubricant (3) is displaced from the cartridge (2) by the released gas. During the gas generation the electric current flowing through the gas generating cell (4) is measured and the charge that has flowed through the gas generating cell (4) is added up. The circuit is interrupted when the added up charge has exceeded a specified cumulative amount of charge. |
