What sort of charger do you have ?

Is it a simple automobile type or a proper regulated marine charger.

If it a proper marine regulated type your batteries should be looked after
properly and last a long time.

On my boat it was the fridge which caused the interference. A 0.1 mfd
capacitor across the supply close to the fridge cured the problem.

I've got excessive static on my FM radio, and discovered it's my
battery charger. Obviously, I want to keep the charger going, but
wonder if anyone knows how to suppress that noise.

Also, my refrigerator works on my batteries, and my charger charges
them. Is this going to decrease the battery life, to be continually
running the refrigeration on batteries, then charging the batteries to
keep up?

thanks for any information,
