I bought a battery tender so as to maintain full charge on my
problematic rider battery. It bothers me that the male plug for the
ting is only 2-prong. Seems to me that I connect it to AC source
backwards, that it could cause charging problems. Can it?

Or am I just paranoid?

Hope this is not a joke. The AC reverses 60 times every second so it will
not mater which way you plug it in as far as the output to the battery.
