    Hello me again lol,is the battery on the NP530U3C a 2 ,3S ?
    What the connection color on the battery corresponds to?
    I want to try to charge it externally using a RC charger and try to see if can put more amps then it is taking now ,the 45000 takes only 31000 at the moment using the laptop charger.
    Can it be done?
    Thanx

    If the battery is two to three years old then about 70% of original capacity is a reasonable level of wear.

    The only thing you can to to try to recover some lost capacity is to run the battery calibration utility in the BIOS. I wouldn't contemplate trying to mess with the charging. It might kill the battery or even start a fire.

    You can work out how any cells in series from the nominal battery voltage with a single cell being around 3.6 to 3.7V.

    I think, but am not sure, that batteries of around the 45Whr rating use 2 sets of cells in parallel.

    I have a NP530U3C-AD5BR Samsung Ultrabook. Despite being on the energy he will not charge batteries. I have changed the batteries with new ones but this problem persist.
    This ultrabook use 4 Cells of LiPolymer battery amounting to 45Wh each cell is 3,7V. There are a board into the packet that control charging, temperature, overcharging, undercharging using a Maxim Max1788 microcontroler. There are 9 wires. 6 wires (3 red and 3 black) that I thing that are for power supply. There are 3 wires, 2 are SMData e SMClock for SMBus V1.1 comunication to the motherboard.
    I don't know what happen because my ultrabook was working normally until when I left it for 2 months without connecting it to light. After that he never charged the battery.

    To your issue, my understanding is once one of the cells die the entire pack is done for. Now without load all the cells on a MultiMeter may look fine but once one of the cells under load collapse the circuitry on the smart batteries just gets lost.

    Even rebuilding these, again from what I've heard, can be an issue as well.
