You'd think a battery like that lasting decades could be quite handy for internet of things devices. You could maybe use a capacitor to accumulate power as the output seems to be in nano amps and low current processors seem to need about 1 uA upwards. Not sure if anyone is working on that stuff?

We probably have to invent a standard that lasts one decade first.


The humble AA/R6 battery has been around since before WW1.

Obviously, the capacity has improved vastly, but the size, terminals and voltage has been with us since your great grandfather wore diapers.


I think GP was referring to a software or service standard for the IoT device to interact with rather than a hardware standard.


Battery technology has improved dramatically since 1840, many quartz watches have battery life measured in years.

What you're proposing exists, it's just expensive because demand is low.


Electrically readable water meters have a lithium battery that lasts for decades.
