WHY CANT BATTERIES ELECTROCUTE PEOPLE?
They can! But you’d need lots of batteries. Single electric cells are very safe. Everyday batteries are safe because their voltage is so low. First, understand that electrocution is not just caused by electric current. Instead it is caused by an electric current inside your body. Currents themselves are not dangerous as long as the path for current is through a wire! Voltage is important here, but voltage is not dangerous unless it causes a current INSIDE your body. Human skin is electrically conductive, but it is not a good conductor. It takes about 40 volts of electrical “pressure” in order to create a dangerous electric current inside your flesh. 40 volts is the “danger voltage.” Anything higher than 40V can shock you. Fortunately, most batteries are way below 40 volts (most are below 12 volts.) Batteries lack the pumping-force needed to create dangerous currents in humans.

Another way to say it: our skin is insulating enough to keep us safe from batteries, but it cannot protect us
