A simple way to test the charge level on alkaline batteries (2015) [video]
Why are people still using alkaline batteries?<p>I have a bunch of Enloops which I pop into everything. Mice, keyboards, game controllers, TV remotes, soap dispensers, etc etc. I also have a bunch sitting in chargers, so I can quickly swap an empty battery with a full one whenever I need to. As far as I can tell, the ones I first bought in ~2015 are still going strong.<p>I do explicitly seek out products which take AAs as opposed to using internal rechargeable batteries, because I can swap out my Enloops in less than a minute, versus plugging the product in and waiting <i>hours</i> for it to finish charging!
