Battery Capacity(mAh):
Milliamp hours: mAh is the capacity of the battery or the amount of charge added to a battery.
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.
Choosing the right charging & discharging rate
Charging at a rate below 0.33C and above 1.0C is not recommended. Charging too slow may prevent the
charger from terminating correctly.
Charging too fast may damage the battery.
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
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.
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.
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.
Battery forming can be performed using the Break-In mode.
Trickle charging
After the rechargeable battery is fully charged in any of the operating modes, the charger will give a small
amount of current to the rechargeable batteries to maintain the fully charged level. This mode is
automatically launched after rechargeable batteries are fully charged and kept in the charging unit. The
signal ―
will be displayed on the LCD.
Batteries are getting warm.
It is common for batteries to get warm while charging. The charger has a built in temperature sensor which
will stop the charging cycle if it has become too hot. Charging may resume when the battery has cooled.
Allow batteries to cool before placing into a product to be used.

FEATURES
Four independent slots
There are four independent charger-analyzers for AA and AAA NiMH/NiCd batteries.
Larger LCD display with backlit for easy reading.
Digitally display various modes during operation. Also the charging current (in mA),
accumulated charging capacity (in mAh), the voltage (in Volt) and time elapsed (in hh:mm)
Seven buttons for easy programming and operation
Four Slot Number Buttons (SNB) to display individual slot operation data during the various
operation mode, and other three buttons for programming and operation.
Five modes of operation: Charge, Refresh & Analyze, Break-In, Discharge and Cycle.
Turbo fast charging - 60 minutes to charge up 2500 mAh battery
Charging current from 200mA to 2500mA.

Damaged battery detection: To ensure safety, the charger performs an “impedance check” at the
beginning of the program. If the battery fails this test, “FAIL” would be displayed and program
will be terminated.
Built-In PTC thermistor to avoid over heat and independent negative delta V eliminates over and
undercharging.
