i've pretty much noticed this from the start, but have only just got around to posting about it now.

i have found when charging genuine canon batteries (nb-2lh) in a genuine canon battery charger (cb-2lwe) an extremely high pitch noise is emmited. it's generally quite intermittent and doesn't get to me however when working in complete silence, it can get quite annoying.

does anyone know what causes this high pitched noise? any possible fixes? and yes, i have learned to charge my batteries in another room from now on.

do the forums not allow paragraphs? i've tried to fix it several times, just seems to revert to one big clump of text.

Just hit return twice between paragraphs.

It's the AC/DC conversion circuitry making the whine.
