The $40 hidden inside a 12V battery | Wise Bread
As the video shows, you simply split them open to reveal EIGHT 1.5V button-cell batteries, each one worth around $5. And as these 12V batteries come in pairs that gives you a grand total of 16 new batteries worth around $80. Not bad for an initial investment of $1.66. Kipkay also goes on to split a 9V battery for use in a battery emergency. You could say these hacks are literally "power to the people." (Sorry, couldn't resist).
