AAAA is popular and as cost-effective as CR2032 (aka: bad value, but less-bad value than most other batteries of this size). Note that CR2032 is toxic, so AAAA is somewhat preferred. AAA and AA have much more energy-per-dollar. I mean, so does lead-acid but I guess that's too big lol. --------- Specialty batteries, like CR123A, seem to fit the bill for this size much better. But those are so, so much more expensive. I feel like the only two cells worth really considering are AAAA and CR2032, despite their deficiencies. |
