| This is an important safety-based question. A breakable, mercury-filled thermometer should not be used in a lead-acid battery because accidental breakage can cause severe sparking and explosions due to mercury creating conductive paths in the electrolyte. Understanding such safety precautions is essential for students studying electrical, mechanical, and aviation maintenance courses.
