Could someone tell me what the MAH reading on this charger indicates . The manual calls it charge capacity . Is it the battery’s capacity ? If it is , the two cells I charged so far are well below the stated cell capacity . Maybe it is the added capacity from charging ?
No, to tell the actual cell capacity, you would need a test function capable of discharging the batteries, which the Miboxer does not have. The mAh reading is just how many mAhs have been put into the battery since it started charging. So if you discharge batteries to 50% and put them in the charger, the final mAh reading should be half of the real battery capacity.
If you want to test the total cell capacity, you need an analyzing charger. Check out the Liitokala Lii 500, Zanflare C4, and Opus BT-C3100. All three are capable of performing charge/discharge tests where they fully discharge the battery to measure the capacity.
You can pick up a Lii 500 for under $20 if you look for coupons around here. I would use the C2-6000 (still a great charger, due to its fast-charging ability) as an every-day charger, but use the Lii 500 occasionally to check for battery wear, or if you need to charge a bunch of cells at once. Oh, and I make it a habit to perform a test on every new battery I get (especially if I get them from a place like GearBest or BangGood) to make sure they aren’t fakes.
C2-6000 is not an analyzing charger, so it cannot measure the cell’s full capacity.
The mAh value you see is an estimate of how much capacity was added to the cell during this particular charging cycle.
EDIT: Doh! Delta beat me to it. 
Thanks guys. I knew it had to be something like that .
New question concerning the C2-6000 . Is 4.17 volts coming off the charger within normal range . Tried a 14500 and a 18650 . Both the same . Put them in a different charger and they come off at 4.20 V .
I’d say 4.17-4.18V is pretty normal.
Theres an explanation on battery charging here by HKJ.

I’m sure he has another article somewhere about batteries coming of the charger at your voltages but cant locate it.
There is nothing wrong with your batteries coming of at 4.17 Volts.
Again, thanks . The charger indicates 4.2 V but the cell measures 4.17 V .
Yes, most cells, if not all, settles to its ‘resting voltage’ immediately when taken off the charger. Let it rest overnight and it will go down some more.
In my experience, a charger that measures my cell/s at 4.20v immediately after taken off are those chargers that are terminating at 4.23 to 4.25v, those kind of chargers that are ‘generic’, one-bay ones that are usually found in a package, low-budget, flashlight/charger/cell combo.
Ok , got it I think . So , the charger I have that the batteries come off at 4.2 are probably slightly higher at termination . And the charger that the batteries come off at 4.17 is probably terminating at 4.2 . All are within acceptable range . Thanks .
Yes, even my iCharger hobby charger, which is considered to be more accurate, while terminating at exactly 4.20v too, also give similar figures like yours.
In other words, while almost all decent chargers terminate at 4.20v, your cell will not necessarily ‘store’ that much exact voltage.
hello, MiBOXER here
About the MAH reading on MiBOXER charger,
If you put Li-ion 4.20V batteries,the Voltage lower than 3.4V
and put Ni-CD/Ni-MH batteries, the Voltage lower than 1.05V
when you charged the battery full, the MAH means the total cell capacity.
And if you put the batteries voltage higher than that(3.4V or 1.05V), the MAH means how many mahs had charged into the batteries
Thanks
Thanks tatasal and pennzy for this great info. I also have a iCharger hobby charger that I thought was defective so I haven’t used it very often. Pennzy, I just received a C2-4000 and it reads the same as your terminating numbers. I like the simplicity of the C2-4000 cause when I start charging a battery the charger tells me what percentage the battery is at any time and how many minutes are left before the charge is complete.
