To test the voltage of the GMCELL USB rechargeable batteries, a precision digital multimeter was used. The batteries were fully charged using a standard USB port on a computer, following the recommended charging time provided by GMCELL. After charging, the open-circuit voltage (OCV) of each battery was measured immediately. Subsequently, the batteries were subjected to a simulated load test. A resistor with a value equivalent to the typical load of a common household device (such as a portable radio) was connected across the battery terminals, and the voltage was measured again under this loaded condition.<\/p>\n
