Abstract
A method and system for monitoring a non-rechargeable battery of an IoT device are described. Voltage values of the non-rechargeable battery when a load is applied to the non-rechargeable battery are determined over a first interval of time. Based at least in part on these voltage values a determination of whether a voltage of the non-rechargeable battery has decreased for more than a predetermined threshold is performed. In response to determining based at least in part on the voltage values that the voltage of the non-rechargeable battery has decreased for more than the predetermined threshold, a prediction of an end of life parameter value for the non-rechargeable battery is performed, and the end of life parameter value is transmitted to an electronic device of an administrator of the IoT device.
