Of what possible interest could knowledge of the chronological age of a battery be?? The number of charging cycles remaining would be of some interest, but this dating information seems quite useless- unless Leica knows something about these batteries they're not telling us!!

A simple experiment proves that it is indeed data-based:

1. Turn on camera with battery that shows the warning.

2. Set the camera's date back one year.

3. Turn off camera.

4. Turn on camera.

5. Press the info button -> The warning is gone.

I get the message on two different cameras. An original M240 and a M246. For the same battery.

 

I only get this message on the oldest battery. One out of five.

 

So combining all this info, I think a firmware fix is in order. For the entire M line.

What is the problem? Just obey the camera and check battery age. Dig up the receipt if needed. :lol:

Yes, certainly. I have done this several times and still the message persists. I would like to stop checking  my battery age and to go out to take a photograph or two.

This may sound a bit radical... Having read the message once, ignore it and carry on using the camea. You'll know when the battery has reached the end of its serviceable life, ie when it no longer holds charge for more than a few hours. I've used li-ion batteries for yonks and I've never had one fail on me yet, and charge retention fall-off is negligeable, When manufacturers say battery life is 1000 charge/discharge cycles, they're probably being somewhat conservative.

I have an Audi (VW Group)and a Leica. Apparently my Audi isn't affected. No warnings on my battery either.

Ever get the feeling you're being left out?

 

Don't worry, I'll invite you to my birthday party.

Both VW & Leica accept that the issues are legit..  They will rewrite the software/firmware, and engineer the remedies.. If your Audi is not affected & your Leica shows no battery warning, mazeltov..

I had to look up 'mazeltov'. Good word. I'll remember that for crosswords. :)
