My grandpa used this method to check if batteries work. He used a flashlight battery, and a piece of wire. This is kinda a ghetto multimeter.

oh my god, i am amazed. never before have i seen any way to check if a battery works or not. i have in past times spent seconds sticking them into the appliance,hoping that one day, a device will be produced to help with my battery related needs.
