EEPROM + Backup Battery

Does the EEPROM require the backup battery to be present inorder to work properly?

Don't know. I know that it doesn't need it to maintain it, like flash memory. Why?

The backup battery is necessary in case there is a power overload so that the microcontroller doesn't reset. It is also used to power the pwms (or at the very least the pwms don't produce the necessary voltage without it plugged in, so therefore anything connected to the pwm wouldn't work properly.
