Abstract
Various embodiments of a battery detector are provided. In one aspect, a battery detector of a portable electronic device is applied to a battery module without an identification (ID) terminal. When the portable electronic device receives a direct current (DC) voltage provided by an external transformer to conduct a startup procedure, the battery detector detects whether the battery module is connected to the portable electronic device or not, and prevents the portable electronic device from conducting erroneous operations.
