I finally switched to Duracell’s rechargeable NiMH batteries last year and won’t be going back to alkaline. They work well even for things like flashlights that need low self-discharge, and I no longer feel like I’m creating waste every time I burn through a battery. I also came across some rechargeable lithium batteries packaged in 1.5V AAA, AA, C, D form factors, but they appeared to be newer and I was unsure about long-term reliability.
