What must be down? A lot of people have done it. All is in that description. Where is the problem?

I think he wants to know how to properly replace the battery
- whether when the voltage is connected to the programmer 12v,
- whether USB is connected,
- or simply replace the batteries without any external 3_volt connections

Hi
I want to replace the battery before it goes flat and the unit useless. So I found this post but not too sure how to go about replacing the battery in a preventative way to avoid ending up with a flat battery

[sniegavirs]

It is all written in that post. That is why it exists.

I plan to replace the battery.
For this:
- solder a socket from an old PC motherboard for the CR2032 battery and solder it to the battery contacts CR2354 on the VVDI board(where CR2354 soldering will not be performed)
- insert a new CR2032 battery into the socket (parallel with CR2354)
- solder out the old CR2354 and solder in the new CR2354 (at the same time, the CR2032 will hold 3V for the VVDI board)
- remove CR2032 and unsolder its socket

Using external power supply is way more easier. If you are that scared add USB cable power as well. That additional battery socket could make it more problematic..

I don't know, maybe you are right, if you do everything carefull

Returning to the topic of the infineon XC2361A 72.
I decided to check.
Is the MCU Reflesh V3 cable that I have really V3.
After disassembly, you can see that it looks like V2, only a different color of the board.
And these two resistors are installed where they should not be in the V3 version.
Can someone more experienced comment on whether my cable needs to be modified?

I wrote about replacing the battery a dozen or so topics ago.
In my case, I powered it via USB.
You have to do it carefully so as not to short circuit it and make sure that the programmer is not deprived of power.
I would suggest using an external power supply.
Because the computer's USB will turn off the voltage when it is overloaded.
