Most devices & gadgets are rechargeable nowadays. The only thing I have that still requires batteries is a headlamp but even those are available in rechargeable varieties. House smoke detectors need a battery too.

    Lithium disposables beat alkaline in longevity, but lose in cost and are only 1.2V.

    They’re about 1.6V open-circuit, and maintain 1.5V under light load for a large portion of their discharge cycle. They maintain 1.5V much longer than alkaline.

    They’re terribly expensive for regular use compared to pretty much any other option though.
