Discharging 4x Sanyo GA at 1A with 50mA D.REDUCE and down to 2.7V I'm only getting ~3250mAh from these, is this normal?
Discharging 4x Sanyo GA at 1A with 50mA D.REDUCE and down to 2.7V I'm only getting ~3250mAh from these, is this normal?
Edit: Same test with my Opus 3100 v2.2: ~3450m/mAh. But I read the opus has higher reading than usual.
My MC3000 had a little episode after i removed a charged 18650 from the 3rd slot:
With the stock fan the internal temperature can raise up to 75C while discharging 4 cells at 1A, this is no good for the life of the components.
Can programming parameters be saved to file (pc or android) and then be uploaded to a second MC3000?
Can the programs be renamed to display on the UI, eg. Instead of 'program 1' can we display "AA dcd 1.25", or even better, someone's name, ie 'PeterD'?
Has anyone attempted to charge 3 aa's in a 1s3p setup in the charger using the quality white D cell adapters available from eBay at about $1/unit and can 4 adapters fit in the charger?
Can the charger be locked so settings and programs are not accidentally changed or lost?
The answer is no to all your questions, except a squirrel has played with parallel charging of NiMH cells (Usual it is not a good idea, they have to be discharged exactly the same for it to work).
The AA cells will be mounted in the adapter permantly except for occasional checking. They will be discharged in the adapter. Would you think that sufficient or should capacity checking on each cell be undertaken to initially match them and ongoing capacity checking be done say every 50 discharges or 6 months? We are using eneloop pro's.
Edit. Has anyone saved and uploaded 'ideal' programming parameters for download if possible and if not is there a ready reference available with most common battery types in the one place?
I would expect that to work. To get them in balance it would probably be a good idea to start with a slow charger: 16 hours at C/10. If you start with full batteries, you can reduce the 16 hours significantly.
Individually charged or inserted in the adapter?
Has anyone tested charging termination problems at the C/10 rate in this charger? Terminate on voltage to avoid this?
In the adapter.
I would not expect the charger to terminate at C/10 and with the above charge it is not supposed to terminate, except on time or capacity.
What was the overall final opinion of the thermal design of this charger? Terrible? Average? Good?
I know that Gauss163 thinks it's terrible, HKJ's review mentions it could be better but doesn't really say there's any issues. Kreisl has his on a laptop cooler. richardcpf is installing his own fans!
Is there anything here to be really concerned about? If so, always, or only when discharging 4 x batteries at 1amp?
The cooling is not really enough to handle the full discharge power, but due to the thermal safety reduction of current it is not a problem. The charger will limit the heatsink to 85C, that is fairly cool for power electronic, they cold have increased this temperature to avoid current reduction, but that would increase the risk of wearing the capacitors out after a few 1000 hours of discharging.
hehe not exactly trueKreisl has his on a laptop cooler.
