Battery change Rollei 35
The battery is a Varta V625PX Mercury button cell. I still have some stock but it is out of sale for many years for environmental reasons. I also own an adaptor to use LR44 (S76) Silver Oxide button cells. The adaptor accepts the LR44 cell and lowers its 1.55 V voltage to the desired 1.35 V.
This is just a ‘test’ video, but you are wellcome to watch it.
