DS3231 RTC No Interrupts on Battery ZS-042 Module

jremington:
How about on battery power? Does this work on the alarm-output-not-functioning modules?

It's like, on battery power, the SQW/INT pin doesn't work at all.

jremington:
People have always wondered whether the chips on these cheap modules might somehow be fakes or rejects, as the module price on eBay is lower that the cost of the chip itself, purchased from the legitimate manufacturer.

And i have 5 of these. xD My hard luck. But this is what is readily available in my area. As I stated earlier, the module still does set the corresponding alarm flags in the status register. It's just that the SQW pin is not pulled low as desired.

Thank you so much for taking out the time to help!
Cheers!
