Ansmann PX28 / A544 / 4LR44 6V Alkaline

My old film camera's light meter finally works again thanks to this battery—it's the exact 6V size I needed and it slid right into the compartment. No more guessing exposures in manual mode.

This 6V button cell revived my handheld light meter after a year of sitting dead, and the shelf life feels solid so far. Voltage held steady through a weekend of shooting, which is exactly what I needed.

Picked up a pack of these for my vintage camera and they fit the battery compartment perfectly without any wobble. The 6V output powers the light meter just like the original did back in the day.
