Hi Tianya,
It is likely that your battery experienced a permanent failure (PF) which means that the safety circuitry determined there is an unsafe condition and the pack needs to be permanently disabled. Typically a chemical fuse is blown inside the pack so you cannot charge or discharge it. It is recommended to safely recycle the battery.

High, unseal code is secret to avoid unauthorized access to the battery settings.
It's set by pack manufacturer (usually Taiwan or Chinese companies), and they know this code, you should mail them and provide sufficient reason you need this code and warranty you will not make it public.
