Hello, I try to powered the DS3231 by backup capacitator 5.5V 0,22F and i can say that is work very good. If I compare price of capacitator and LIR2031 the capacitator is 1/3 price. It can backup time module for 24h sure (tested). Now I try if it possible to backup it for all weekend. That is enough for me.
