william_roberts4 Posted July 9, 2010 Share Posted July 9, 2010 <p>Hello, I just got a K1000 SE and some lenses. I was trying to put a new battery in the body, but it seems like the compartment is corroded shut. Rather than wrestling with it and messing up the body, is there any way to open it, maybe some cleaner or something that won't mess up the body? <br> Also, is there a source for the tiny screws that tighten up the focus ring on lenses? <br> Thanks for your help!!</p> <p>William</p> Link to comment Share on other sites More sharing options...
charles_stobbs3 Posted July 9, 2010 Share Posted July 9, 2010 How about removing the bottom plate, battery cap and all. Tht would allow you to acces it with different tools. And even buy a bottom plate in better ccondition. Link to comment Share on other sites More sharing options...
curt_saxton Posted July 9, 2010 Share Posted July 9, 2010 <p>Hi William,<br> Generally for corroded battery caps I set the camera upside down and either let a drop of Ronsonol lighter fluid or WD-40 drip around the cap and sit overnight. Usually helps.</p> Link to comment Share on other sites More sharing options...
gabor_szabo3 Posted July 9, 2010 Share Posted July 9, 2010 <p>Unscrew the bottom plate like Charles recommended. Then, use some lemon juice or vinegar on a cotton swab to clean up the<br> battery spillage. Use penetrating lube like PB Blaster as a last resort. </p> Link to comment Share on other sites More sharing options...
tom_cheshire Posted July 9, 2010 Share Posted July 9, 2010 <p>If the battery has been in there a long time it might have expanded a bit thus jamming the cover. In cases like that we have had to apply heat with a soldering iron to make the metal expand a bit or, if that didn't work, grind through the rest of the slot so a proper screw driver could be inserted and spin off the cap. </p> Link to comment Share on other sites More sharing options...
william_roberts4 Posted July 9, 2010 Author Share Posted July 9, 2010 <p>Thanks everyone for your help, I ended up taking off the bottom plate and using some cleaner to loosen up the battery cover. So now I have to get a battery and test the camera out... might have to sell one of my other cameras so I can keep this one......<br> PN is one of the most useful websites...</p> Link to comment Share on other sites More sharing options...

frank.schifano Posted July 10, 2010 Share Posted July 10, 2010 <p>There's heat, and then there's heat. Tom's talking about warming it up a little bit - just enough to get the metal to expand slightly. He's not talking about hitting it with a blow torch.</p> Link to comment Share on other sites More sharing options...
jim_momary Posted July 10, 2010 Share Posted July 10, 2010 <p>Batteries usually 'explode' in a fire due to the boiling of the electrolyte and the issuance of steam. If the battery has leaked, it's probably all dry and when 'cooked', no steam just roasted cell is the probable result.</p> <p>The typical electrolyte used in mercury batteries was either sodium or potassium hydroxide. Thus, using an acidic solution will aid in the dissolution of the 'hoarfrost'.<br> <a href="http://en.wikipedia.org/wiki/Mercury_battery">http://en.wikipedia.org/wiki/Mercury_battery</a></p> <p>Leakage also plays havoc with copper wires. I've fixed some older rangefinders wherein the wires drew up the electrolyte (capillary action perhaps) from the battery holder and slowly had dissolved over time.</p> <p>We all know we should remove batteries from stored equipment, but I dare say we seldom do. I'm guilty.<br> Jim</p> Link to comment Share on other sites More sharing options...
ernest-b Posted July 10, 2010 Share Posted July 10, 2010 <p>Well, okay, Frank.</p> <p>If the cover loosens before the battery explodes, a beginning repairman will know he hasn't warmed it too much.</p> <p>On the other hand...</p> <p>http://www.instructables.com/answers/can-you-safley-solder-a-small-button-cell-battery-/</p> <p>"It will explode, it has happened to me."</p> Link to comment Share on other sites More sharing options...

john_shriver Posted July 10, 2010 Share Posted July 10, 2010 <p>The K1000 (thankfully) doesn't use a Mercuric Oxide battery. It uses a "76" cell, either Manganese Alkaline or Silver Oxide (best).<br> Removing the bottom plate and soaking in vinegar seems best to me.</p> Link to comment Share on other sites More sharing options...

wendell_kelly Posted July 11, 2010 Share Posted July 11, 2010 <p>FWIW-<br> I had a battery cover quite firmly corroded in place on a Spotmatic. The problem was exerting sufficent torque on the cover to have it come free. I wasn't able to do this with the coin slot.<br> I removed it by drilling two small holes in the battery cover near the outer edge. I then inserted two finishing nails to act as pins and applied some WD40 around the circumference of the cover. After about a twenty minute wait, I slipped a slender screwdriver between the "pins" and used it as a lever to twist off the cover. It came right off for me. I was able to clean the threads on the cover and reuse it.<br> I did this with the bottom plate on the camera - one might have to do something like this even if the cover is off the camera.(Use a hand drill to make the holes, not a high speed electric drill)</p> Link to comment Share on other sites More sharing options...
bob_miller4 Posted July 13, 2010 Share Posted July 13, 2010 <p>It might be more cost-effective to use a separate meter or none.</p> Link to comment Share on other sites More sharing options...
william_roberts4 Posted July 19, 2010 Author Share Posted July 19, 2010 <p>Thanks everyone for your responses. What I ended up doing was taking the bottom plate off and soaking the battery cover with lemon juice and then there are two notches on the inside of the battery cover that needle nose pliers fit into snugly and then loosened it up that way. I think I need to clean the battery compartment and check the wiring because the meter isnt working. Thanks again for all the suggestions!!</p> <p>William</p> Link to comment Share on other sites More sharing options...
