Advertisement Posted April 25, 2011 Posted April 25, 2011 Hi Washington, Take a look here Non-Leica M9 Battery Test. I'm sure you'll find what you were looking for!
lct Posted April 26, 2011 Share #82 Posted April 26, 2011 You're welcome but full battery drain must be done before each charge otherwise the camera (M8) meter doesn't show 100%. Is it the same with yours? Link to post Share on other sites More sharing options...
Washington Posted April 26, 2011 Author Share #83 Posted April 26, 2011 I don’t know yet. I have been busy on another project and I haven’t done much with the camera. What you say doesn’t surprise me though…. I guessed this may be the case. I would imagine if I put the same battery back in the charger with the battery at say 75% and charged it…. it would do the same old thing…. show 75% in the camera though it’s fully charged. Awww, I’ll just get off my butt and go do it now and see. Link to post Share on other sites More sharing options...
lct Posted April 26, 2011 Share #84 Posted April 26, 2011 …. show 75% in the camera... Or even less... Link to post Share on other sites More sharing options...
Washington Posted April 26, 2011 Author Share #85 Posted April 26, 2011 I was just using that as an example…. the actual battery partial charge one recharged from didn’t matter ….. the camera would show whatever charge % you started from no matter where you started from even though the battery was fully charged. If I was a clever electronic guy I’d modify the charger to drop the battery to 3 volts before it’s fully recharged. But I’m not that electronics savvy. Yes, the charge would take a bit longer… but the meter would alway work in the camera. (maybe) Link to post Share on other sites More sharing options...
tdtaylor Posted April 26, 2011 Share #86 Posted April 26, 2011 Washington, just wanted to thank you for all your effort and reporting. And by all means, do let it mess up the Frankencamera! 1 Link to post Share on other sites More sharing options...
k-hawinkler Posted April 26, 2011 Share #87 Posted April 26, 2011 Advertisement (gone after registration) Washington, The same here. Thanks for sharing your hard work. I have a question. If one is willing to carry a spare fully charged Leica battery, couldn't one just use a fully charged other battery and ignore the false reading? Wouldn't that work? Best, K-H Link to post Share on other sites More sharing options...
Washington Posted April 26, 2011 Author Share #88 Posted April 26, 2011 Sure… the battery is full the camera just doesn’t show it. And, if you use it until the camera stops working THEN you have reached enough discharge for it to recharge AND have the in camera battery meter show full charge. This is all pretty weird but so far this seems to make the meter work. Why? I dunno why. Today my battery meter showed 85%…. I stuck the test battery into the charger, fully charged it and the camera still showed 85%. So, it seems the only way to get the camera meter to work is dropping the voltage. AND, I have only done this with one battery…do all third party batteries work this way??? I dunno. Link to post Share on other sites More sharing options...

lct Posted April 26, 2011 Share #90 Posted April 26, 2011 Problem is full discharges are good for Ni-CD or Ni-MH batteries but not for Li-ion like ours apparently: "The smaller the depth of discharge, the longer the battery will last.

Bert N Posted April 27, 2011 Share #91 Posted April 27, 2011 Full discharge of the battery is apparently recommended by Leica. An excerpt from the M9 user's manual: "A new battery only reaches its full capacity after it has been fully charged and – by use in the camera – discharged 2 or 3 times. This discharge process should be repeated every 25 cycles." Problem is full discharges are good for Ni-CD or Ni-MH batteries but not for Li-ion like ours apparently:"The smaller the depth of discharge, the longer the battery will last.

lct Posted April 27, 2011 Share #92 Posted April 27, 2011 (edited) 2 or 3 times is not each time. Edit: I'll try 3 full discharges with my Oeges and see if the camera meter works but i doubt it much. Edited April 27, 2011 by lct Link to post Share on other sites More sharing options...
Washington Posted April 27, 2011 Author Share #93 Posted April 27, 2011 Sorry Ict, I wasn’t purposely dismissing your observation, rather speaking of what have observed with what I have here… I’m running the drill on another ‘’off-brand’’ right now: this from a different source (but all appear to have identical cases!) And: THANK YOU for that link…. good stuff!! cheers. Link to post Share on other sites More sharing options...
lct Posted April 27, 2011 Share #94 Posted April 27, 2011 No problem at all thanks for keeping us informed of your findings. Link to post Share on other sites More sharing options...
Washington Posted April 27, 2011 Author Share #95 Posted April 27, 2011 Latest observation, er, mistake: I was using the bulb discharge thing to another third-party battery…. I forgot about it and it drained the battery dead-ass flat. Zero. So, expecting nothing would happen I put it in the Leica charger anyway….. and it charged up fine and showed 100% on the camera scale. Link to post Share on other sites More sharing options...
k-hawinkler Posted April 27, 2011 Share #96 Posted April 27, 2011 Washington, Thanks. Good going. Fantastic. Isn't that how they discovered some glass and glue - by mistake? Good luck! Best, K-H. Link to post Share on other sites More sharing options...
Washington Posted April 28, 2011 Author Share #97 Posted April 28, 2011 You betcha! This is goofy fun so I drained another 3rd party flat… and it’s in the charger now. You can’t be too serious about this stuff because it’s all silliness! Link to post Share on other sites More sharing options...
Bert N Posted April 28, 2011 Share #98 Posted April 28, 2011 Would you mind describing what you used to connect the discharge bulb to the battery? Welcome, dear visitor!

lct Posted April 28, 2011 Share #99 Posted April 28, 2011 2 or 3 times is not each time.Edit: I'll try 3 full discharges with my Oeges and see if the camera meter works but i doubt it much. Did three full discharges to no avail as expected. Battery meter shows 100% at first but as soon as i do a partial recharge, the meter stays at its previous level. First time i see this. I'm using 15+ batteries currently, all third party's for Canon, Nikons, Epsons and Digilux 1 with no problem at all. Only exceptions are M8 and M9 so far...

Washington Posted April 28, 2011 Author Share #100 Posted April 28, 2011 Bert N, That’s flat copper braid sold on little spools that’s used for wicking the solder out of connections one is disassembling . I just cut a couple of short strips an soldered about 1/4’’ inch of one end so it would push between the battery contacts in the slot. I believe they sell it at any electrical store that sells soldering supplies. 2 Link to post Share on other sites More sharing options...
