I tried again today, this time using the charger inside the house instead
of an unheated outbuilding. *Initially I got the same problem so rang the
service center up and they said the charger must be faulty and they'd send
a new one.

However, after a few hours - now the charger has come up to room
temperature (from around freezing) - it seems to be working fine and
charging the batteries

Have others experienced this, or does it sound like a fault? *There's no
operating temperature in the instructions, although the charger does say
for indoor use only (and I'd claim my outbuilding is still indoors!).

Thanks,

Im sure the manual would have informed you it was out of range, mine
does. LiIon will be ruined trying that.

As I said, the manual does not indicate any operating temperature for any
of the equipment.
