Package Contents: 2 * PX625 Battery Adapters Review: A well machined adaptor which allows LR44 battery's as replacements - Back in the day 1950’s through to 1080’s many cameras and small electronic items like calculators etc; used a Mercury Battery know as a PX625 or similar designation which were about 1.35Volts. then they were discontinued and for some years there as not an alternative. Then people started to produce these adaptors which allowed a LR44 1.5v silver oxide battery to be used as a replacement. Whilst having a recent sortout of my unused cameras, among which was a Olympus OM 1 and a Pentax Spotmatic camera both used the old PX625, these two adaptors provided the answer to see if they still worked. The adaptors are of reasonable machined standard, with the LR44 fitting perfectly into the adaptor, likewise the adaptors fitted into the cameras as they should. So overall I was pleased with them as I have now have two useable cameras.
