Exodies Posted September 22, 2017 Share #2 Posted September 22, 2017 Does it have a “check battery age” function? Quote Link to post Share on other sites More sharing options...

Link: http://charger.nitecore.com/CHARGER/CAMERA/ULM240/ I own it (it arrived a few days ago), it charges the battery even with a 1000mA USB power supply. I haven't tried it yet with a power bank or a solar charger. Quote Link to post Share on other sites More sharing options...

Echo63 Posted September 23, 2017 Share #5 Posted September 23, 2017 I havent got one yet - it is on my list of things i need. This way i can charge the battery from the car, computer, solar panel or powerbank when i am away from home. It also appears to be much smaller than the supplied charger.

pop Posted September 23, 2017 Share #6 Posted September 23, 2017 I haven't yet found the time to do any meaningful tests, with the exception of checking to see that it does indeed charge a battery. However, it's small, it's light, it works, it takes only 5V, it's finally available and the maker has a good reputation for chargers, I believe. It also has a very fancy display which looks very scientific; I haven't the foggiest whether I need all that data it throws at me. Some time this winter I might be able to do some comparisons. Don't hold your breath. Quote Link to post Share on other sites More sharing options...
jevidon Posted September 25, 2017 Share #7 Posted September 25, 2017 Advertisement (gone after registration) The M240 has such a long battery life, i really don't worry about losing power or needing a charger on the run. I always carry a second charged battery, but I have never had to switch to it during a day's shooting. But then again, I'm not a wedding shooter and my daily shooting is well within the 300 shot range. Quote Link to post Share on other sites More sharing options...

lawman Posted September 25, 2017 Share #9 Posted September 25, 2017 The charger works well from any USB source. I strongly suggest you get a short USB extension cord with it as the one attached to the charger is very short. 1 Quote Link to post Share on other sites More sharing options...
ymc226 Posted September 26, 2017 Share #10 Posted September 26, 2017 I purchased 2 of the NC USB chargers each for the M9, M240, Q and SL. I tested all the chargers on my batteries and they took comparable times compared to the Leica OEM chargers. In addition the NC ones tell if the battery remaIns in a good versus other condition. The price of the chargers seem so much more reasonable for what it is, a simple device. My reason for getting multiple chargers is the various prior posts reporting unexpected Leica charger failures that seem inevitable. Given their smaller size, I won't be using my Leica ones either at home or when I travel. 1 Quote Link to post Share on other sites More sharing options...

RonM Posted October 2, 2017 Share #13 Posted October 2, 2017 I just received my charger and a partially discharged battery is on it now. The included instruction sheet is very sparse. I am getting alternating displays; one is something like 35degrees C 84mah and the other display shows 8V and 44mah. Both displays change values somewhat with each cycle, and the battery charging icon steps through as I think it should. How will I know when the battery is fully charged? Does the display just turn off? Quote Link to post Share on other sites More sharing options...

I think it displays "done", if I remember that correctly. 1 Quote Link to post Share on other sites More sharing options...
ernst_leitz Posted October 2, 2017 Share #17 Posted October 2, 2017 Manual here http://charger.nitecore.com/pdf/ULM240_UM_EN.pdfThink it says "END" when finished charging 1 Quote Link to post Share on other sites More sharing options...
RonM Posted October 2, 2017 Share #18 Posted October 2, 2017 (edited) Manual here http://charger.nitecore.com/pdf/ULM240_UM_EN.pdf Think it says "END" when finished charging Yes, I have the manual, but if you read through that sheet, it does not say what the displays mean, or what indication there is when charging is complete. That is what I meant by a "sparse" manual. You and pop are correct however, it does show "end" when charging is complete. Thanks for your help. Anyone know what the changing 'mah' displays indicate about the battery or charge conditions? I understand the battery icon display and the final charged voltage dispaly, but not the two changing mah readings.

I had a M-8 charger that misfunctioned. The M & M-P (240) batteries do last a long time and I have never used more than 1 in a day but what happens when you are on a vacation that exceeds a couple of days and your charger, died, got stepped on or was left behind in a hotel room. A very lightweight backup that can be powered by multiple USB sources is nice to have or buy two and leave the Leica one at home. I paid $22.50 USC on eBay with free shipping.

Yes, I know mah is milliamps per hour, but what I was looking for was an explanation of the actual numbers that appear (and change) as the battery is charging. The function of the unit is to charge the battery, and it does appear to do that very well, but since the information is on the display, what use is the information is it giving, since the numbers are constantly changing, and each set is different. Or is this just some fancy bells and whistles to make the unit "look" more technically sophisticated? Edited October 3, 2017 by RonM Quote Link to post Share on other sites More sharing options...
