i dont know why,can someone help me with this ..do i need to replace the battery? or whats wrong?

The battery has possibly developed a fault, one or more of the cells has died so the conditioning system can not read the capacity so it is giving a red sign.
I would say you are due to replace your battery sorry a little tip would be to get one
