I've looked back over recent battery posts but nothing
obvious helps. I park up my N reg HSE RR outside the
house and take of for a week's Red Sea Scuba holiday
and when I get back it is flatter than a very flat
thing. Not: won't crank but: nothing even glimmers.

The battery is 70AH and a year old. Is there
something draining it that I can unplug? Assuming it
was reasonably charged when I left it to kill it like
this implies nearly half an amp of drain but when I
charged it and put it back nothing seemed to be drawing.

What am I doing that's stupid here?

Some info here:

Also, I hear that Oregon Scientific weather stations can use a
frequency which somehow keeps part of the electronics awake.

Serves you right for sodding off to the Red Sea whilst the rest of us
are shivering at Stoney.

So it's out with the spectrum analyser then.
I never thought I'd have to use that on the car...

But the sea is still warm and flat so if you're
diving Stoney Cove it's self inflicted.

sounds like the infamous alarm thing. I assume it's a P38A type RR?

basically, something interacts with the alarm and causes battery drain. I
forget the details...

AndyC will be along in a bit, or someone else savvy in this.

Both BMW X5 had the problem, leaving my wife stranded at a railway station
twice, and early Mk111 Range Rovers as well.
They are all sorted now and my own Mk111 has not let us down once yet.
