This is the second reply along these lines I've seen, and I have to
interject here that I've often charged batteries from dead flat with this
same Tender. Granted, on bikes that made less extravagant demands on their
batteries, but the point is that it's never taken more than overnight to go
from too-weak-for-the-neutral-lamp to firing right up. That's why I'm
surprised to see it not work this time.
