Gentlemen,
We've all had this problem at some time or other. Your car's battery
doesn't stay charged for extended periods. Maybe it's 2 weeks, maybe 2
or 3 days. Something is leaching current from your battery and if it's something more involved than a simple boot light not turning off, you
could be in for a world of pain.
In the old days before everything got crazy, we'd just pull fuses one
by one and find the circuit repsonsible easily enough. But things have changed and your car now has a brain and likes to remain sentient at
all times. This can be a major PITA as it means you may have to wait
anything up to 2 hours between fuse-pulls for the systems to settle
down again into a genuine quiescent state. And given the sheer number
of fuses in a modern car, you may be looking at a *huge* amount of
time to get through them all properly. However, there *is* an
alternative which overcomes these issues. This helpful hillbilly
explains how to go about it - and all you need is a cheapo DVM.

Oddly enough my van battery just flattened unexpectedly.

Looking at the charts, I think my vehicles only have two sizes of fuse
in the fuseboxes. The small ones look like "mini", but is the "big" one
what the Americans call Standard or Maxi?

Both of my cars have a battery suicide mode.
One as the battery goes flat will discharge though the door central
locking. It has no current when there is charge in the battery but
once it drops to a low voltage it ensures complete discharge.
The other triggers the alarm, an after market Cobra alarm. This again
ensures the battery is pancake flat. If I'm away when it starts going
off I have no way to detect that it's done this.
I have small solar battery maintainers. These are not effective in
winter with lack of use. Last winter during lockdown and only one
shopping trip every 8 days (time to use 4 pints of milk) I had to put
the cars on charge every week.

All the central locking systems I've come across with electronic timers (other than perhaps vacuum operated early ones) have some quiescent
current. And if it has remote operation, the receiver too.

Why not simply disconnect the battery when the car is unused for a while?

It sounds as though you need one of the chargers that are usually sold
by Aldi or Lidl.You can leave them connected for ever, they adapt to
whatever the battery requires.
the XP power battery charger I got from Aldi resets and stops charging
if power is lost.
