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.

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)

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

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.

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. If at all possible, avoid frequent full discharges and charge more often between uses."

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.

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.:)

Would you mind describing what you used to connect the discharge bulb to the battery?

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...

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.
