Leisure Battery discharging?

Hi All,
  I have a two month old Warwick XL, on the Control Panel, I have selected the Leisure Battery as the source battery for power (as I assume that would then be the one that the AS Monitor tracker uses).
I have set the Solar Panel to only charge the Leisure Battery.
I have had about eight notifications of low battery, the last one on Monday morning at 6.00am. That morning I drove down to the secure site where the van is stored, ran the engine for half an hour, left both batteries at 14.1V.
This morning (Friday, so three days later) I get another AS Monitor Low Battery notification at 6.00am.
Am I doing something wrong, or can anyone let me know if I'm doing the right thing and this is a Service Centre issue?

Many thanks,
Synthia

Note also that these days there is quite a lot of variation from van to van.

If your van has the "traditional" split charge system, then running the van at idle for half an hour probably won't get the leisure battery anywhere near fully charged. That's partly because an alternator running at idle can't quite generate the level of power outpt that it would while driving around, and partly because the engine battery gets charged quicker (because of limitations in the wiring between the two batteries).

If your van has a DC-DC charging system then the situation will be better, but you should not expect it to be fully charged in half an hour if it was heavily discharged (e.g. at or below 12V for a lead/acid battery).

Note also that the 14.1V that you saw at the end of the charging is a bit misleading. If you had waited for 30 minutes you would have seen both battery voltages drop away, unless the solar panel was providing input at the time. A fully charged battery should be around 12.8V, but you will only really see that after the effects of charging have settled down (and only then if there are no other loads on, or charging inputs to, the battery).

As Peter says, switch the EC700 off completely to prevent the leisure battery discharging.  Also has the advantage of re-setting the system when you switch it back on.

Many thanks all, I'll give that a go.

Synthia - the advice given is absolutely correct.  What the manual doesn't explain is that when the EC700 PSU is not shutdown, it draws about 7Ah every 24 hours from the leisure battery, even when there is no habitation load, which at this time of year is more than the standard fit solar panel & regulator can generate.  Result flat leisure battery and eventually a flat vehicle battery as the EC700 will draw its power from the vehicle battery when there is none left in the leisure battery.  Solution shutdown the EC700.

As others have intimated, you should take your campervan out of storage and connect to an EHU for a day to ensure that both batteries are fully charged before it goes back into storage and the EC700 shutdown.  When the EC700 is shutdown, no solar charge will go to the leisure battery but if it is fully charged to start with and in good nick, it should be fine without charge for a good 3 months.  The leisure battery's resting voltage and therefore state of charge can be monitored remotely under Locate on AS Monitor when the EC700 is shutdown.

That explains why I'm having the problem and the solution, I will do this tomorrow and have a closer look at my AS Monitor page.
Many thanks!
