The invention relates to a method of diagnosis of a state of end of life of a determined type of battery such as a cell, in particular a lithium/manganese cell. According to this method, during the use of a battery of the determined type within the framework of a given application, periodic measurements are performed of the voltage across the terminals of the battery and of the corresponding ambient temperature, each measured value of the voltage across the terminals of the battery is compared with corresponding values previously stored during a specific preliminary calibration phase, a counting is established of the number of measured values below the corresponding values measured, and an alert signal warning that the end of the life of the battery is delivered after counting of a number n of measured values below the corresponding values stored.
