They do not last.
I got these for my Gossen Luna Pro light meter. I ordered them about a month before an event I wanted to use them at. Well covid caused the cancellation of the event, so the meter was put away.<br /><br />About six weeks after installation, I went to use the meter to find no response. The batteries were dead, completely dead.<br /><br />So basically this purchase was a complete waste.  Too expensive for such a short life span.
