mA = milliamp

1000 millimeters per meter
1000 milliamps per amp
etc.

Interesting Fact:
Three nations have not officially adopted the International System of Units as their primary or sole system of measurement: Liberia, Myanmar and the United States.

When using the refesh and analyze mode on the C9000, at the end of the cycle I get Mah reading and voltage reading and time(in minutes).

1) Basicaly do I use the Mah and voltage reading I get at the end of the cycle to match my batteries?
2) The final Mah reading is smaller then the actual rated 9000 Mah of the battery, but the battery's performance in the Miniz is fine. Why is this Mah number smaller?
3) The time it takes to charge should I take this into consideration when matching cells?
4) Is there a way to obtain internal resistance of the cell with the C9000? I know the charger does an impedance test and if its high then its recomended to git rid of the battery but can I get actual numbers for resistance?

Thanks

1,bit of both,mine are matched by mah and volts(you can match mins but 90%of the time they do match up the same if you do mah anyway)
2,the manufacturers rating is not correct under normal circumstances,they probably obtain that figure from the lowest charge/discharge they can get away with.
my orion 900's are all around 700-780mah,duracell 1000's 800-900mah the closest ive measured is intellect 750's at 740-760mah but they only tend to last a season.
3,nope
4,no reading for it,i use a muchmore cell master for that but 1 cell at a time

Hi Maha.
First would lake to thanks this company for the excellent fine product specially the Maha C-9000 and the superb customers support service we as consumers can enjoy
Well to the point that bring me here. My reading after I charge my Orion’s 900's on both of my C-9000, the final reading is practically the same as the ones posted here by mk2kompressor, @ 700-780mah. However if I charge the same batteries in another charger (not mentioning name as respect to Maha) the readings are higher, been charged at the same mA, any particular reason for this?
Perhaps the other charger delivers imprudent amount of mA that overloads the batteries?
Conceivably a battery issue?
Thanks in advance for your time & cordial reply to my dilemma.
Cheers
