Command F4 resets the value of a tag’s Battery Counter to zero (0x00). This command is intended to be used when replacing the batteries in an active RFID tag and will reset the value of the Battery Counter to zero (0x00).

Located at tag address 0x0000, the Battery Counter stores a one-byte value that indicates the number of operating hours that the tag has been in use since it has last had its internal batteries replaced. A tag should have its batteries replaced after it has accumulated 15 hours of use. When this value reaches 0x0F, battery life is in a condition of decay and should be replaced.

To retrieve the Battery Counter Value, execute Command 02 and note the value stored at address 0x0000 on the tag. Reading address ZERO on the tag should only be performed by one station in a typical assembly line.
