How to choose the right battery charger?

• 1. 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.
• 2. Charge Speed
  Common battery charger uses constant current charging mode, charge rate mainly related to the current provided by the battery chargers.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 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.
• 3. Charge termination control
  Small current 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 battery charger; If you need to select the higher price rapid charger for camera, you'd better kown many about performance of the battery and the camera battery charger. For example, a 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 battery charger can provide a smaller current selection.

Why does the battery charger always fail to work?

Generally speaking, there are problems in circuit connection for charger, such as interface department, wires and adapters to connect first-class. Because these sites are so easily bent that power line are likely to be broken, or fail to connect well. Once this happens, it could be repaired by changind a new line.
