These are the batteries most famous for powering the BIOS chip in your PC. Besides that application, we use these batteries in our Tiny Lantern Kit and around the office to test LEDs, they are handy little suckers! Stack 2 together to get 6V, or 3 to get 9V, or.....you can do the math, the gist of it is that they are easily stackable to achieve higher voltages. And because they are made with Lithium they are quite the powerhouse for their size! You'll find these for $5+ a piece in stores but we have them for a more affordable price here.
