What batteries can i use to replace the varta 50 DK in the Mark 3. And will they be leak proof. Also diagrams and schematics as I may try to fix this myself. I am a retired printed circuit designer.
Thanks, RFK42

Hi RFK42,

The replacement for the V50s are the Varta V80s. They are slightly larger in dimensions, but should snap into the black bottom the same way as the old ones. I've also used V40s which make for a smaller footprint, but they lack the capacity of the larger ones.
