Everyone knows MMC use cheaper alternatives. They appear to be putting cheap electrons into the cars. Probably those free electrons we’ve heard about...maybe they are trying to conduct themselves better?😬

My Plus 4 Trad lose charge in a week or so. But my Roadster will hold charge for weeks and weeks.

Dave,
that is weird!
Now you mention it Aldermog, our S2 Roadster, held charge like a modern car, rather than a Morgan!

My Roadster always seems fine, though I do trickle charge it anyway every so often.

My Plus8 holds a charge well. Odyssey battery that is at least 8 years old and is usually kept on a Ctek. When not the battery has kept its charge. The only drain is from the immobiliser.

My oldish Banner battery seems to hold at between 12.6v and 12.7v for weeks although I sometimes put it on a Ctek especially in this colder weather.
However I have removed the immobiliser and I always turn off the battery isolator switch if the car is left for more than a couple of days.
Possibly a stupid question to the more electrically minded amongst you but to check residual current draw do I simply disconnect the earth lead and run the multimeter between the lead and the battery negative terminal?

Bear in mind the standing voltage of a battery after an hour or so of use gives an indication only of the state of charge of the remaining capacity left in it. Towards end of practical life a high voltage reading may not indicate enough energy to start engine, with natural discharge having an ever increasing effect on voltage measured some time later. Regarding measuring standing current draw make sure you initially use the 10 amp range available on most multi-meters to avoid damage. If current draw is too low to measure you can then try a more sensitive range.

Thanks for the info about the residual current measurement.
Mine has a 15A reading and then the next step down is 200mA.
Also I have to use a different connector on the multimeter for the 15A setting and only use the other for mA readings.

Update: 4 December 20
I haven't used Tarka for 8 or 9 days. When I parked the battery voltage was 12.6v.
Today it was 12.3v
So, I'm beginning to believe that the battery I had was faulty: this on holds its charge.
When it is at 12v I'll either drive the car or put the charger on.
