Good product
Received 2 batteries each in their own  plastic packaging and received them on time.  The batteries look (and measure) exactly like the original PX13 batteries.  Installed them and they worked perfectly.  As far as longevity I won't know for a while Podue to being used in light meters which aren't used very often.<br /><br />In the advertising LR44 batteries were mentioned, but as I have found out, they have nothing to do with these PX13 battery replacements.
