First, the battery backup - I must admit that I've never bothered with this on either my London 8 (also 2+6, which rarely sees the light of day) or it's slightly larger brother, my London 16 (which runs 24/7, supporting twelve extensions around the house and connecting to four exchange lines - BT, CNet x 2 and mobile network adaptor). On the latter, I have a label on the master extension (221) setting out the commands I need to re-input after a power outage.

To obtain a seventh extension card (which I could also do with for my London 8, whose second exchange card is faulty) you would probably need to find a dead London 8 with at least one good extension card.

Your mention of using digit 1 (LD only) is equivalent of timed-break recall, which works on my London 16. TBR shouldn't be polarity-sensitive. I don't think earth recall is supported.

Edit: giving further thought to this, I'm not absolutely sure that a seventh extension would be supported.
