Halfords changed the battery without any discussion. Well Done Halfords!
Installing the battery I connected an ammeter between the negative pole and the ground cable.
1.2A with the ignition off.
Clearly something is wrong... it was associated with what sounded like a relay cycling inside the electronics box.
I think this is something for an auto electrician, it is beyond me....!
For now, I'll leave the car connected to the charger.... Was that immediately after switching the car off? It can take some time for various modules like the ECU to power off. Are you positive there isn't a tracker fitted? My son's car had had a black box fitted and not removed by a previous owner. When its internal battery ran out it drew off the main battery and drained it after a few days. I assumed no tracker as I bought the car from Morgan Motor Company.... now you have me wondering. The relay cycling noise occured 2 days after removing the battery connections. When I re-connected the battery and put the Ammeter in circuit I got this strange noise.

Odyssey or try a Varta.
Expect over ten years life.
I had a BL Unipart battery on my MGB - guaranteed as long as you keep your car. They didn't figure 22 years and after about six batteries, they stopped the deal.  Trust a Yorkshire lad to fully exploit an extended warranty

Peter, I've had a clicking from around the passenger dash area when the ignition was off and key out, turned out to be the boot was unlatched.

Update.... Since driving up to Williams for the annual service the car has sat in the garage for 7 days. The battery has lost only 5% of its charge and is showing 12.9v. In the past the battery was golding charge for only 2 or 3 days. So why the improvement? My conclusion is that over the last 12 months the car has not had any good, long runs and the car needs these to charge properly. So, COVID has damaged my Plus 8.....
