Uma izinga lokushisa lasebusika liphansi kakhulu, ibhethri lezimoto zikagesi lizophulwa ukuphila (ukubola kwekhono), libe buthakathaka (ukonakala kokusebenza), uma lesi sikhathi ukushaja kuzobeka ingozi efihliwe yokufa ngobudlova (imvula ye-lithium ebangelwa ingozi yesifunda esifushane sangaphakathi. i-thermal runaway).Ngakho-ke, lapho izinga lokushisa liphansi kakhulu, kuyadingeka ukushisa (noma ukufakwa).Isifudumezi esipholile se-ThePTC sisetshenziselwa kakhulu ukushisisa indawo yabagibeli, kanye nokuqeda isithwathwa nokususa inkungu amafasitela, noma amandla okuphatha ibhethri ashisayo ashisa ngaphambili.
