Sony camera prompts that the camera cannot use the battery. What happened?

Most models of Sony's cameras and camcorders have special requirements for batteries. To put it simply, there is a circuit specially developed by Sony in the battery, which has Sony's parameters and can only be done by Sony's original battery.

If you buy a new battery, you can't use it, which is normal (not before the original battery). If the original battery has been in use, and now it suddenly can't be used, it is that the internal circuit of the battery is broken. It is recommended to replace the battery with a new one. At present, there are some cracked batteries of different brands on the market, but based on Sony's stable model, it is recommended to buy original batteries to replace them.
