Alto (2011 K10B) What's a normal and acceptable battery load with ignition off?

Engine running shows 14.6V on the terminals, with the clamp around the earths on the battery terminal showing about 20A.

Load test on the battery abysmal, and the same with the engine running.

I would like to ensure no parasistic drain, ideally prior to replacing the battery. I'm seeing about 0.04A with ignition off, door open and electrics timed out to turn courtesy light and anything else off.

Thanks in advance for any help given.

The recent back story.

A few weeks ago the car wouldn't start with a sluggish starter turnover speed. Neighbours tried to jump it for her, kept it turning enough to blow the main fuse.

With the starter off the car, it turned over slowly and only showing 40A on the clamp meter so a replacement starter and battery terminal fuse block was sourced and fitted.

At the time the battery was charged and held 14V, load tested between 200-300A on the old school heater element load tester.

Car started for a couple of weeks and all seemed well with the exception of the radio and courtesy light not working, along with the central locking.

All seemed well for a couple of weeks until I had time to look into the minor issues.

The car then started, drove a mile and wouldn't start without a jump again.

It drove an hour home to me to look at, parked for four days, started yesterday to warm up then turned off. Changed oil and filters then back to no starting without a jump. Radio fuse had blown. I don't know if central locking is on the same fuse or if displacing the fuses to check them gave it a clean connection. It peaked at about 200A on the clamp starting, but generally about 70A.
