How to choose a suitable battery pack?
- battery voltage is the same with the original.
- battery size same with the original. Or similar/smaller.
- battery plugs same with the original (check the plug diagram)
Match the above three conditions, in general, this battery can be used.
The larger of MAH, the longer use time. Different voltage, battery size, shape, can be same voltage, because the battery combination of different ways, the shape is not the same. You can leave a message about your old battery, please pay attention!!!
