2.1.3 NiCad OR NiMH Battery Detection
With the lack of a contact, as with Lithium Ion batteries, the CH0003 will assume that the battery is a
Nickel-based chemistry (NiCad or NiMH). The charger will charge at a constant current of 1A while
sampling change in voltage. When a negative change in voltage is detected, the peak has been
found and the charge is complete. There is a 6-hour safety timer that will terminate the charge if the
battery never peaks. On the NiMH battery are thermistor contacts for each section that detect the
battery’s temperature.
2.1.4 Temperature
Detection
If the battery’s temperature is above 65°C when it is put on to charge, the charger goes into a fault
condition and waits until the battery cools down before going into fast charge. If the battery gets
above 65°C while charging, the charger will suspend the charge until the battery cools down, and
then go back into fast charge to complete.
2.1.5 Unattended
Charging
The Charge Modules, which detect open or shorted cells. If a defective cell is detected the CH0003
will not start the charge cycle.
Once Charge is completed the CH0003 will maintain the battery being charged with a trickle charge
if battery is left connected to the CH0003
In no event will a battery be overcharged using the CHARGING ALGORITHM of the CH0003.
2.1.6 Wide Range Input Voltage
Allows for operation from nearly any AC or DC power source likely to be encountered worldwide.
2.1.7 Conditioning
Cycle
Automatic discharge/recharge function included. The conditioning cycle can be activated individually
per battery at operator’s option.
2.1.8 Product Name Plate
