Ansmann CR2032 3V Lithium Battery

Popped one into my bike light and it’s been running strong for hours without any drop-off. The 3V output feels reliable, and the battery life is noticeably better than the cheap ones I used before.

The voltage held steady in my digital calipers even after a week of light use, which is better than the last batch I tried. They fit perfectly into my camera’s battery compartment without any wobble.

These 3V cells read a solid 3.08 on my multimeter straight out of the pack, which is better than some other brands I've tried. They've been sitting in my camera's battery compartment for a month now with no voltage drop.
