I have a CR2032 battery connected to a DS3231 module as backup battery. When the module is connected to 5V the battery voltage is at 4.3V and without power 3.7V.
That means the module is trying to charge the nonchargeable battery. I couldn't find a rechargeable (LIR23032) battery to buy and after some research someone in forums suggested to remove the diode from the module...
If I keep using the CR2032 battery for long run 24/7, how long will it last? Is there a risk of explosion?
Is there any other way than modifying the module itself?
