Well I can assure you Simon, that in this case you are completely and utterly wrong
The actual fault is described as "CANBUS Messages Failure Instrument Pack 3" by T4, and the symptoms are specifically no rev counter, temperature gauge, or heated rear window.
It is not caused by low battery voltage, a spike, or indeed anything other than an internal failure of
one specific IC on the DDE4, and replacing the battery, charging it up, disconnecting it for a while is going to do absolutely nothing
If you wish to try this out, unplug your instrument pack, then see if it is possible to activate the heated rear window

P.S. almost every DDE4 with this defect is from an age range encompassing VIN 1M, and rarely if ever are these units ever water damaged.
I tend to use them as donor units for conversion of NNN100693 ECM units to make them into NNN100692SR
