Seems we need to replace the CMOS battery ... before we dig in to find Apple have likely used an unbranded/blank battery ...

What spec battery do we need for successful replacement?!

Cheers in advance

Mac Pro, 10.14

Apple uses a BR2032. A CR2032 will work but will have shorter life.

CR2032 are used in garage door opener controls and car-key fobs, so they are readily available.

This is a non-recharging, long life Lithium coin cell, nominal 3 Volts. If the one you take outs under 3 volts, it is used up.

The battery holder is delicate. The risk of breakage if you do not work carefully and use a very bright light is high.

Remove the one you have because it will provide the information you need.
