How am I out of AAA alkaline batteries? Well, fortunately I have a ton of left-over rechargeable AAAs¹ so I guess it's time to throw some into my also left over very nice charger and get them topped up, just in case.
¹ I used to have AAA powered bicycle lights, back before everything went LiIon and became much better. Well, technically I still have the bike lights, I just don't use them any more.
