Operation of the Magnum Inverter charger.

Called Magnum tech support, We went thru all the settings, I had them right, 13.2 v is the proper setting for flooded batteries so I asked why the batteries run down so quickly. and as I Thought the batteries are showing their age, he asked If I had ever ran an equlizer charge, and I had not, So we are doing one now.

Thanks for the help..
