Hmm...Interesting. The only way I know of it making a "voltage spike" is
if it is connected to a battery with an open cell. Batteries absorb the
spikes, normally. It's how they charge...(c;


I think they were talking about higher than normal charger output voltages
in 15+v range that some chargers may put out under certain conditions.

Regarding spikes - Don't we get a "spike" when we turn on the charger?
Instead of say 11.5v, we suddenly have 14.5 or whatever. Anyway, that's
what my voltmeter tells me!
