Naw, lithium ion batteries have a high self-discharge rate. Not a good idea for this kind of project.

Since we're talking eWaste, my guess is a bunch of 6V alkaline batteries strung together in an old CRT monitor.



It's a good idea to use primary cells for this case, but did they?


They seem to be vague about the device and its batteries, but they do say they utilized an external battery.

With no mode of recharging, why bother with rechargeables?


Lithium ion batteries have the lowest rates of self-discharge.
