I am pretty new with posting here on WUS but following the forum from years.
So on the topic I have bought one G-2300-9v second hand which has faded digits (the previous owner claims 3 months ago the digits were ok and after keeping it in the drawer it became like that) and from what I tested and readed here on the forum I conclude that it is not the battery.
I found a Raysman DW-9350 in bad condition but the module seems to be ok. So my question is if it will be possible to fit Raysman module (1584) to the G-2300 (module 2184)
To me they look the same judging by the display. I couldn't find pictures of the 1584 module itself to compare it more precisely.
The only difference i found looking at the displays was the displaying of the year on 1584 is only with two digits and on 2184 is with four digits.
Here are some images of the G-2300
