Coin Cell: CR2032, 3V | |||
Reasons: | |||
* Cheap | |||
* Low self-discharge | |||
Unsolved problems: | |||
* Does not deliver a lot of power (~0.1mA per spec) | |||
* Not a lot of capacity | |||
Alternatives: | |||
* AA battery (large, but cheap and easily available — only delivers 1-1.5V though) | |||
* 2xAA battery for 2-3V (very large!) | |||
* Lithium Polymer Battery (like the one used in the Magic Shifter) | |||
* Solar Panel | |||
