1. A device battery, comprising: a battery controlling microprocessor, an electrically erasable programmable read-only memory and a storing component,
the battery controlling microprocessor being connected to the electrically erasable programmable read-only memory, and the storing component being connected to the battery controlling microprocessor and the electrically erasable programmable read-only memory;
the storing component being configured to store a storage address to which battery data is written last time; and
the battery controlling microprocessor being configured to write battery data to the electrically erasable programmable read-only memory in a cyclic erasing writing mode according to a storage address currently stored by the storing component;
wherein the storing component comprises: a monitoring unit,
the monitoring unit being connected to the battery controlling microprocessor;
the monitoring unit being configured to monitor whether a battery data writing event occurs; and
the storing component being specifically configured to, when the monitoring unit detects the occurrence of the battery data writing event, clear the currently stored storage address and store a storage address for writing this time.
