• Replacing a Battery with a Solar Panel and a Super-Capacitor

    CR2032 batteries usually power devices with very low energy requirements. A typical use-case for such a battery is, keeping an internal clock active even if the main power supply is not available. The device will be able to maintain the correct date and time even when turned off and not connected to any other power source. An example device that makes use of this is a common mainboard - an essential part of every computer.
