My M arrived today--it is black, I paid list for it, and I got on the list shortly after announcement.

 

Everything is working fine, except the battery. The camera shows it at 50% charge when it should be showing full charged. I took the battery out of the charger when the both the green and yellow/orange lights were solid (not blinking).

 

I put it back in the charger and let it sit for about 45 more minutes and when placed back in camera the display still showed the level at 50%.

 

Is this normal behavior? Has anyone else had a similar issue?

 

Thanks

Agree not normal. My battery was draining VERY rapidly until I charged it about three times. Suggest you drain that battery by turning on everything you can and attempt to get it down to like 25% and re charge to see if it improves. In the meantime, put Leica or your dealer on notice so that you can learn the camera while they get you a new one. OR if they have a demo in the store, swap that one into your camera.

 

No battery, no fun.

See Jaaps reply to similar queries on the M9

 

It can be due to the camera thinking that fully charged is 50%.......

 

I think its a bit like my car which shows different 'miles to empty' depending on what my driving was before I filled up last.....

 

The solution (if I remember correctly) is to run the battery down completely to zero, ignoring various warnings and making sure the camera will not work when switched on and the battery is really flat.

 

Fully recharge and insert. The camera now has correct calibration for full and empty and should show 100%.....

I went out today and drained the battery shooting. Now I feel a little conflicted about what to do. I recharged the battery and it now shows 100%, so it seems to be working fine. Yet MJH says to replace the battery.

Battery capacity is not estimated by measuring the voltage output or anything like that. Rather, electronics in the battery counts the current inflow into the battery when charged and outflow on discharge and the camera interprets both figures to arrive at a capacity figure, ideally compensating for ageing and temperature. It's always a good idea to deep discharge the battery so that the counters are forced to reset and the battery learns the true capacity.

 

If it's fine after a few charge/discharge cycles, I don't think you have anything to worry about.
