Thank you for purchasing the Powerex MH-C9000
Charger-Analyzer. Read these instructions carefully
and thoroughly before operating this unit. IMPORTANT
SAFETY INSTRUCTIONS. READ AND SAVE THESE
INSTRUCTIONS.
OPERATING THIS PRODUCT INCORRECTLY CAN
CAUSE DAMAGE TO THE BATTERIES.
READ MANUAL COMPLETELY BEFORE USE.
GENERAL BATTERY EDUCATION
GENERAL PRECAUTIONS
•
Do not charge battery cells other than NiMH or NiCD. Please check
with the battery manufacturer to ensure it can accept the
programmed charging and discharging rates. Do not expose the unit
to rain or moisture due to the risk of fire.
What is 0.1C, 0.2C, etc?
“C” stands for the battery capacity and the number in front of it is the
fraction of the battery capacity. For example, 0.1C means 0.1 times the
capacity for the battery. For a 2700mAh battery, 0.1C would be 0.1 times
2700mAh which equals 270mA.
•
•
Do not operate the charger if it appears damaged in any way.
Always place the battery cells with positive tip facing the top.
Incorrect polarity may cause fire or explosion. Observe polarity
diagrams located on the charger.
Choosing the right charging & discharging rate
•
Do not allow the unit to be exposed to direct sunlight. Operate in
well-ventilated area. Do not place unit on the carpet.
Charging at a rate below 0.33C and above 1.0C is not
recommended.
•
•
Do not allow the battery terminals to become shorted.
To reduce the risk of damage to the power cord, always pull by
connector rather than the cord.
Charging too slow may prevent the charger from terminating correctly.
Charging too fast may damage the battery.
•
Use only the supplied adapter or optional regional and car adapter
offered by Maha Energy. Using third party accessories voids the
product warranty.
Typically speaking, slower charging rate will yield better battery
performance but requires longer time. Faster charging rate may not
charge as fully and battery temperature can be higher.
Battery Matching
FEATURES & SPECIFICATIONS
In most devices, usually two or more batteries are used together. When
batteries are used in a series, the performance is limited by the worst
one. In other words, one poorly performing battery can significantly
reduce the device runtime.
•
•
•
•
Four independent slots for AA or AAA NiMH batteries.
Backlit LCD display.
Battery matching refers to grouping batteries with similar “actual”
capacity. To perform this, use the Refresh & Analyze mode to determine
the battery capacity. Group batteries with capacity within about +/- 5% of
the rated capacity.
Digitally displays capacity, voltage, time and current.
Five modes of operation: Charge, Refresh & Analyze, Break-In,
Discharge and Cycle.
•
•
•
19 selectable charging current from 0.2A to 2.0A.
10 selectable discharging current from 0.1A to 1.0A.
Worldwide power supply.
Battery “Forming”
New batteries and those stored for extended period become chemically
deactivated. Battery forming is a charge-discharge-charge cycle which
forces a full charge into the battery at a very slow rate. This process
activates the battery. In certain cases, it needs to be repeated two or
three times.
Charging Current:
Programmable from 0.2A to 2.0A in
increments of 0.1A
Battery forming can be performed using the Break-In mode.
Topoff Charging Current:
100mA
Maintenance Charging
Current:
10mA
Discharge Termination:
Voltage 1.00V
Discharging Current:
Programmable from 0.1A to 1.0A in
increments of 0.1A
Capacity Storage Memory:
12 (Cycle mode only)
PRINTED IN TAIWAN A03-3713420-496
If REFRESH & ANALYZE mode is selected:
The charger will prompt for the charging rate by flashing “SET CHG
RATE.” Use the UP and DOWN key to choose the desired current.
Press ENTER to make the selection.
Then it will prompt from the discharging rate by flashing “SET
DISCHG RATE.” Follow the same procedure as above.
6. To ensure safety, the charger performs an “impedance check” at the
beginning of the program. If the battery fails this test, “HIGH” would
be displayed and program will be terminated.
If BREAK-IN mode is selected:
The charger will prompt for the battery capacity in order to calculate
the charging and discharging rate automatically. “SET BATTERY
CAPACITY” will flash. Use the UP and DOWN key to choose the
desired current. Press ENTER to make the selection.
Typically alkaline and extremely aged battery will fail this test. For a
rechargeable battery, it is recommended for the battery to be
discarded.
NOTE: This test is not performed for the discharge mode.
If this detection is believed to be incorrect, a discharge can be
performed first.
7. While executing the programmed function, the charger will display
the battery status for each occupied slot consecutively. The screen
will first show an arrow below the active bank and display the
information. The next slot(s) occupied follows.
If DISCHARGE mode is selected:
Press the SLOT button at anytime will jump to the next occupied
slot. Press this button multiple times if necessary to go to the desired
slot.
The charger will prompt for the discharging rate by flashing “SET
DISCHG RATE.” Use the UP and DOWN key to choose the desired
current. Press ENTER to make the selection.
The following information is displayed on the screen:
Current:
This is the number followed by the unit “MA.” This is the
approximate charging or discharging current. Note that this number
will go up and down due to the pulse charging.
If CYCLE mode is selected:
The charger will prompt for the charging rate and discharging rate
similar to the other modes. In addition, it will also prompt for the
number of cycles to be performed by flashing “SET CYCLES.” Use
the UP and DOWN keys to choose the desired cycles. Press
ENTER to make the selection.
Capacity:
This is the number followed by the unit “MAH.” This is the
accumulated charging or discharging capacity. If it is charging
capacity, “CHARGE” in black box will be shown. If it is discharging
capacity, “DISCHG” in black box will be shown.
PRINTED IN TAIWAN A03-3713420-496
For CYCLE mode, the discharge capacity of the final cycle is
displayed. “CYCLE HISTORY” icon will also be shown. Use the UP
and DOWN key to access discharge capacity for all the cycles
performed.
The capacity information will be stored as long as the battery is
inserted in the charger. It will be lost upon removal of the battery.
Note the charging capacity is usually higher than the actual capacity
of the battery owing to some energy lost as heat. Charging capacity
cannot be used to judge the performance the battery. Instead, it can
only be used to determine the progress of the charger. It is normal
for this number to exceed the actual capacity by as much as 20-
30%.
