How to identify the lithium battery of Sony np-fv 100a original camera?

The best method is discharge method, and other methods are difficult to distinguish. Now the high imitation is very clever, and it is difficult to distinguish it from the appearance. Discharge means that the camera is always on or taking pictures to see how long the battery can last. The exact time depends on the camera manual, which will indicate how long the FV 100 battery has been used on that camera. If the difference is not very big, it is original, otherwise it is high imitation. If the original battery is cheap, it must be high imitation. Pay attention to this and don't be greedy for petty gain. Those anti-counterfeiting signs, those with high imitation, can also be made. Really ugly.
