@sysop408@sfba.social @jalager@mastodon.nu @kwayk42@sechtor.social @astrid@infosec.exchange I used to have a flashlight that took 4.5V batteries that were actually three A cells in a bigger box. Unlike the 9V ones, which are quite hard to dismantle, these had a top that was very easy to pop off and so you could see the wiring inside. I've never seen an A cell anywhere outside of these ones, but when I was young you could buy the 4.5V ones in most hardware stores. I haven't looked for one for a very long time, so I've no idea if that's a good thing.
