Shimano Di2 Charger (SM-BCR2))

Anyone got a SM-BCR2 charger laying around?

No-one?

Somewhat relatedly: anyone in London got one of these chargers I could borrow for like an hour to see if this Di2 set I bought on eBay just has a dead battery or is actually hosed?

Got one based in SE, can charge at mine for a bit?! Pmd if interested

Thanks! As I'm kinda far (W9) I might just end up buying one of these as I'm going to need one sooner or later anyway. I'll PM if I change my mind. Thanks again.
