Panasonic CR123A Lithium Battery (3V)

Pulled these out of the package and they felt solid, no loose ends. Used them in a flashlight and they've been holding steady for weeks without a drop in brightness. Exactly what I needed for a 3V setup.

These little cells hold their voltage impressively well, I've had a set in my flashlight for over a year of steady use and they're still going strong. The 3V output has been perfectly consistent, which is exactly what my gear needs.

Have been using these in my car key fob for months and the voltage has held steady. Much better than the generic ones that would die every few weeks.
