Once you get the cover off and remove the battery, you probably have dried green battery acid residue inside...Be careful how you clean it because at the bottom of the hole is a round metal piece that might be eaten away by the acid and if it comes loose there are wires underneath... I hope this helps...regards, bob cole In a message dated 6/22/2007 6:11:58 P.M.

The metal battery cover of a cute Petri Color 35 (which I just bought from in the neighbourhood) should be opened with a coin, but does not move, even with larger coins and rather much power. I guess it's strongly oxydated. Can I operate with very small drops of acetic acid, or another acid? Or penetrating oil? Unfortunately the battery compartment is inside the body, so a treatment with liquids should be done very carefully. Thanks in advance for any advice Didier _______________________________________________ Leica Users Group.
