First question - am I right in thinking that when you plug in the 240 volt external electric lead you are charging BOTH the engine battery and the leisure battery? Both are normal 72 amp Varta car batteries and are only 18 months old.

Second question - my leisure battery is going flat when the camper is not used for week or two. I understand that the only job of the leisure battery is to power the Eberspacher and to power the 12 volt fridge when driving between say home and the campsite?

I cannot understand why the leisure battery is being drained down so quickly when it is "resting". Surely the clock and lights on the Eberspacher control panel cannot be using much juice or are they?

I did get in the habit of disconnecting the negative lead on the leisure battery, when leaving the camper unused for a few weeks and maybe I need to go back to this practice.

Any thoughts on this? Is there perhaps a component that I should be checking?

Thanks for your responses.

I dunno mate.......... I only does the sewers,
But the Joker manual I have saved (for just such an occasion) in my docs. Says.................

Battery Charger:
The battery charger operates automatically. As soon as you have attached the 220V current to the vehicles external socket, the charger is ready for use. The charger status of the starter and second battery comes from electrics in the charger. The batteries are then charged up the max setting. Once the batteries are fully charged, the charger will switch itself off.
3 control lights on the right of the display show the charge status of the second battery.

Green = more than 12.5 volts
Yellow = less than 12.5 volts
Red = less than 12 volts

Elderly batterys become incontinent, (won't hold a charge) just as we all do. (I dribble as well, sorry should be drivel I'm told)....A lamp and bulb, (or a multimeter) in place of the disconnected earth lead of the leisure battery, (bulb will glow/light, meter indicates a voltage...you've got a leakage) and then pulling one by one any fuses connected to the leisure battery circuit, will isolate the problem item.... which will be connected to the fuse that when removed, puts the light out. Unless you have two problems in which case...... I'll get me coat.
