Possl pvc batteries flat!

[Gingernuts]

After a lovely long weekend in Arran, arrived back home and emptied the van!
Forgot to plug it in on hook up, now 2 weeks later both batteries flat, key fob wouldn’t work and wouldn’t start! Nothing showing on battery panel! As the van is new to me I don’t know all the little idiosyncrasies peculiar to this van. The only thing that I found was the 12v switch was left on at the panel! So what’s draining all the power?
Ps It doesn’t have an alarm!

All lead/acid batteries will self discharge, but not that quickly so either the batteries were duff or there is a largish parasitic drain though the latter would normally only drain one battery. Your batteries are dead now and will have to be replaced anyway. When you replace them put a meter in series and see what the drain is.

Was the fridge and tv aerial booster (if fitted) turned off ?

 

[Gingernuts]

No to aerial booster, will check fridge

A lot of control panels just doing nothing other than being on will draw .25 of an amp which is 6 Ah's over a 24-hour period and multiply that by 2 weeks and you have a dead battery.

The panel takes a relatively small drain, but over a couple of weeks it mounts up. 200mA over 2 weeks is 66Ah, a large chunk of a 100Ah leisure battery. and that's without the other items mentioned so far.

Do you have a removable front radio? Found ours drained the battery if left in situ even though switched off.

Ok thanks will check the radio also
