    What is the difference between Ni-Cd, Ni-MH and Lithium Ion batteries?

    Batteries in portable consumer devices such as a laptop, camcorder, cellular phone, etc., are typically made using either Nickel Cadmium (Ni-Cd), Nickel Metal Hydride (Ni-MH) or Lithium Ion (Li-Ion) battery cell chemistry. Each type of rechargeable battery chemistry has its own unique characteristic…

    What are the possible reasons for zero voltage or low voltage?

    1. When batteries are short circuit from outside or over discharged/over charged or charge reverse.2. When battery is continuously charged with high current, the electrode swells so that the two electrodes contact directly, short circuit is caused.3. Batteries are short circuit or slightly short cir…

    How over discharge affect battery characteristics?

    After the battery has been fully discharged and voltage lowers to the designated value, if we continue to discharge the battery, the battery will be over discharged. We usually set the cut-off voltage according to the discharging current. We often set cut-off voltage as 3.0V (Lipo cell) for battery …

    What problem will occur when mixed use batteries of different capacities and different voltages?

    When mix use batteries of different capacities and different voltages, leakage or short circuit may occur. These problems occurred because some of the batteries will be over charged and some others are not charged to full capacity. When these batteries are discharged together, the batteries with ful…
