Canon

Canon are made from the highest quality parts, the Canon are tailored made according to the original size, whether the Canon appearance, size and quality are the same as with the original. Every Canon should be under strict quality control including filtration and safety testing of voltage,capacity and Canon core before leaving the factory, and has passed the authentication of CE, UL, EMC, CQC, ROHS, etc.

    Common charging method has the following three kinds:
    • Constant current charging: In the charging process to maintain a constant current to the canon battery, it is the most common charging method, the general chargers are constant current charging.
    • Constant voltage Charge: In the charging process to maintain a constant voltage to the canon battery charger, circuit current decreases as the battery voltage gradually increase.
    • Constant current constant voltage charging: First, to constant current charging the battery, when the battery voltage increases to a certain value, the voltage remains the same, to constant voltage charging the camera battery, the circuit current is reduced to small, until the completion of charging. Nickel-cadmium and nickel-metal hydride batteries are used constant current charging mode, lithium-ion batteries generally use constant voltage constant current mode.

    How to choose the right canon charger?


    when the user selects a charger naturally have different preferences, where the recommendations focus on performance options.
    • Charge Speed
      Common canon charger uses constant current charging mode, charge rate mainly related to the current provided by the canon battery charger.The greater the charge current is, the faster the charger charged. And the length of charging time if beyond related to charging speed, also depends on the size of the battery capacity. Should be noted that the greater the charge current on the canon charger and the battery's internal system design higher quality requirements. Under normal circumstances, the greater the charge current, more heat will be caused in charge process, the battery performance may be in greater damage. The inferior quality battery charger and batteries in high current fast-charging is very vulnerable to leakage and other safety issues.
    • Charging efficiency
      Charging energy input the battery not all turned into the battery storage of energy, and part is spent on the battery inside the side-effects, and transformed into heat during charging, so charge efficiency is always less than 100% . The charge current should be controlled within a certain range when charging, the charge current is too big or too small will reduce the charging efficiency. For high-current fast charger, the charger also requires a special charging mode design, in order to improve charging efficiency.
    • Charge termination control
      Small current canon battery charger generally use the time control mode. High-current fast canon charger commonly used -△ V control and other control mode of combining the design, intelligence level higher. The larger the offered
      charger current, more complex the charge termination control method is, the higher the cost and price is. For the user, to choose based on their own actual situation. If the using battery doesn't have a high capacity, or the charge rate is not a particularly value, you can choose an ordinary canon battery charger; If you need to select the higher price rapid charger for canon, you'd better kown many about performance of the battery and the charger. For example, a canon battery charger can provide the maximum charge current of 1000mA to use to 600mAh capacity Ni-MH battery charging, which needs that the battery is specifically designed for high current charging, or to ensure the canon charger can provide a smaller current selection.
