Renew Cr 2025 Battery In Boots Tens Machine

[Hard@it]

I have had a Tens machine for a good number years, it is now still working but display has gone and I want to replace the disc battery inside. I do not want to break the casing by using a knife roughly, does anyone know how to gain access?

all i can find on the net is this for a mini boots tens machine cant see anything for a full size tens regarding a disc battery
3. Initial use
3,1 Insert the battery
1.Turn the battery
compartment lid anticlockwise using a coin.
2. Use a pointed object to
loosen the lid.
3. Place the battery in the
battery compartment so
that the positive terminal
(+) faces upwards.
4. Close the lid by turning
it clockwise.

i presume the display and power for the tens is from the same battery
