Flat auxiliary battery

Does anyone know whether the charger has a 'low' voltage cut-out? I.e. If the battery voltage drops extremely low (1.0 volts) will the ZIG charger refuse to function?
On a second point has anyone managed to get to the charger to check it? It is located under a seat with no obvious way of getting to it.

I assume that's a hypothetical question because a lead acid battery with a terminal voltage of one volt  is totally stuffed.

You don't say what year but the Zig X7 will drive current into any voltage (up to 13.8V) if the battery is capable of taking current. It will also work as a power supply with no battery connected at all.

I've never seen an X3 but I'd be amazed if it wasn't the same. As far as I know the only difference between the two  is the available current output.

Can't help on how to get at it though.

Thanks Brod
Thing is the aux battery is VRLA. I am concerned that it might be a gonner, only bought last summer. Tayna batteries seemed to think it might be recoverable. It is currently on charge from a separate charger.
We got to this point after verifying everything else was giving correct readings, all fuses ok and relays. The van's charger LED indicates on but even so none of the 12V items will function. Now with the separate charger connected all the 12V items are ok. Waiting until tomorrow to see whether the van's charger will take over when I disconnect the separate charger. If it doesn't then I might be looking at a new ZIG as well as a new battery.
Hope this makes sense.

Sequel is the battery was rescued and has been given the all clear after a load test.

Excellent!  

To be honest I wouldn't have given much for your chances of recovering the battery from such a low state of charge but it shows it's always worth a try. Would I be right in thinking that the battery was in that state for a very short time?

Have you proved that the Zig is defunct? A working Zig should be able to charge anything that's capable of being recharged.

I can't be sure how long it was so low but in it's favour it is relatively new, just six months old.
The Zig did prove to be dead. A/S fitted new one last Fri and all now OK, phew!
Thanks for your interest.
