Battery current calibration. The procedure is as follows on my Sargent ec325 psu :-
With the charger turned off and the power turned off at the control panel with no LED's on, press and hold the leisure battery button, press the power on button and then release both buttons. Wait for the LED cycle to complete while the calibration takes place. The power will now turn on and the calibration is comple.

Isn‘t that a display reset? You can’t calibrate a battery.

If the system has a watts in /watts out = state of charge level then yes the system may be able to be calibrated, but as said above, you can't calibrate the battery.
About the closest thing to a calibration i can think of would be a desulphation charge.

Didn't work on my Sargent

Took my batteries to an auto electrician mate who put a load on them over night and did a drop test and they hold a charge and both reading exactly the same. So looks like the batteries are all good. Hes going to come and check the motorhome electrics to try and find where the electrical drain is.

It might just be a trick of the light, but that top battery indicator is showing red (bad) and the bottom one is green ?

Looks like that to me too...the top battery is dead but those magic eyes arent 100% reliable.
And those terminals need a wire brush and some vasoline smearing on them.

Get your eyes tested Papa They are in perfect condition and well lubricated with proper battery terminal spray (that sticky green stuff you can see but seem to think it's corrosion)
