Hi,
Am new to this forum.
I am using DS3231 RTC and i need it to start time from default each time the battery is connected. No external 5V is available. I understand the every time the battery is removed and re inserted it enters a reset mode and waits for VCC only then will the battery action come in. My question is how can i bypass this as i want the time to start from default the instant i put the battery in.

Thanks in advance.

Without additional hardware, you can't.
If the battery also power an Arduino, then when the Arduino boots, it can check the DS3231's status and start its clock if necessary.
