I would recommend letting your battery go completely flat before you begin. I would imagine that there is less chance of a fire if the gets damaged while completely discharged compared to a fully charged battery. I bent my battery really out of shape extracting it. A scary moment. It was some comfort to me knowing it wasn’t carrying a lot of energy.
