    Guest Battery charger Drawing power OUT of the batteries when its unplugged???-gctid818676

    I have a guest battery charger model 16102, and when its unplugged, it draws power out of my batteries... is this the way its suppose to work with these chargers?

    all other chargers ive ever encountered, when they are unplugged, there is absolutely no power draw back to the charger...

        I had one onboard that did the same thing. Very small draw when unplugged. The manufacturer said it's normal, although I wasn't impressed.

          after talking with Marinco tech support and understanding a bit more about how the guest "smart" charger works and what we should expect when troubleshooting (which is NOT in the manual), the guy (Dave) said when the charger is disconnected from the batteries, then reconnected, it WILL have a draw for about ten minutes, and it will eventually go away ... and although the charger does have a problem with not being able to be adjusted like it should be able to with the buttons, I think it may not be the basic problem... I found a solenoid that has the bakelite housing around the battery stud broken, and it seems the battery post was slightly pushed in and touching the contact bar inside the relay (but not enough to activate the circuit). when I pulled on the wire firmly it came apart... the draw dropped to about 20 milliamps, which is probably the memory in the stereo or some other electronic device., or an error in my meter...

          so I cant blame the entire problem on the charger but Marinco said they would replace the unit under warranty due to the "adjustability" problem found with it.

            IMO the majority of chargers have a back feed draw on the batteries if left connected to them, and the mains supply is disconnected, I have even seen batteries drained to a state of no recovery if left like this for very long (many months) periods, its possible that they were not in the best condition, but it definitely killed them off.

            I agree it should not be the case, but it is always safer to disconnect the batteries from the charger when the supply is off for long periods at a time.

            Hope this helps.
