I cannot seem to find one that does not BUZZ. So called desulfation that is a ripoff in that ALL BATTERY CHARGERS BUZZ without any circuit changes. Why should I have to buy a capacitor?Float 13.3 @ 25c temperature compensated.I'm serious. Do any of these gizmos not have Herb Tarlek grade stupidity?

Do I need to look up Herb Tarlek?

Hi,My Magnum sometimes hums even when the batteries are fully charged. It is annoying.

I guess I've got too many other things making noise in my coach? Never noticed sound from my Magnum unless it's working hard charging or inverting.

Mex,I have an older version of one of these. No buzzing at all ... as there's nothing to buzz because they're solid state. However they have the usual problem - expensive. I spent big bucks for mine years ago when I was heavy into bass fishing ... but solid state innards can eliminate the buzz:http://www.promariner.com/fr-fr/products/waterproof-chargers/prosport/gen3
