You've mentioned those before, but I wonder, just because the
manufacturer declares the maintenance free, does that carry any weight
what so ever, would they be accepted by a BCO as not needing access?

I thought I'd seen various people slagging off similar sprung contacts
which are a bit more common on European fittings?
