sanyasi Posted March 29, 2013 Share #1 Posted March 29, 2013 Advertisement (gone after registration) 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 Jack Siegel Link to post Share on other sites More sharing options...

StephenPatterson Posted March 30, 2013 Share #2 Posted March 30, 2013 Definitely not normal. It sounds like a bad battery. 1 Link to post Share on other sites More sharing options...
algrove Posted March 30, 2013 Share #3 Posted March 30, 2013 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. 1 Link to post Share on other sites More sharing options...
thighslapper Posted March 30, 2013 Share #4 Posted March 30, 2013 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%..... 1 Link to post Share on other sites More sharing options...
Salander Posted March 30, 2013 Share #5 Posted March 30, 2013 According to the manual, you may have to repeat the process 3 times before the battery is fully calibrated 1 Link to post Share on other sites More sharing options...
sanyasi Posted March 30, 2013 Author Share #6 Posted March 30, 2013 I'll be out today taking photos so I will follow the recommended course and bring a second camera. Thanks. Jack Siegel Link to post Share on other sites More sharing options...
Bill W Posted March 30, 2013 Share #7 Posted March 30, 2013 Advertisement (gone after registration) I have three batteries for my M9 and MM and I regularly drain them and charge especially if I have not used them for a period of time. Even my oldest battery is still working great. Link to post Share on other sites More sharing options...
mjh Posted March 30, 2013 Share #8 Posted March 30, 2013 Is this normal behavior? Nope. You should get that battery replaced. Link to post Share on other sites More sharing options...
sanyasi Posted March 30, 2013 Author Share #9 Posted March 30, 2013 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. 1 Link to post Share on other sites More sharing options...
mjh Posted March 30, 2013 Share #10 Posted March 30, 2013 If it stays that way it might have been just a temporary glitch. But a battery that stops charging beyond 50 percent ist quite unusual. Link to post Share on other sites More sharing options...
marknorton Posted March 31, 2013 Share #11 Posted March 31, 2013 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. 5 Link to post Share on other sites More sharing options...
