    It should shut off an give you an alarm when done. As long as you put your setting in right. Are you charging thru the balancer?

    I use a Shultz so it just shuts off when done.

      It all depends on how many Mah you need to put back and at what amp rating you charge at...
      If you put back 100% (5000mah) and charge at 5amps it will take 1 hour to charge..
      If you only need 2500mah at 5amp charge then it will take 1/2 hour to charge..

        Man that would worry me. The charge rate must be pretty low. If not toss the charger asap.

            Is this what you bought?

            Ask questions before you wast your money that charger will take years to charge 5000mah
            you want at least a 50watt charger

                650 milliamp.... little over 1/2 amp. It is not bad for the cells but will take forever.

                Get something that goes as least to 5 amp.

                    Does it have any light that turns red or green? If not who knows...not good for cells if it does not sense the charge and shut off.

                    You can put a Astro blinky between the balance connector and pack connector and it will tell you more.

                            it will charge up to 3 cells each led is for one of the cells green means that the cell is done. How many cells is your battery?
