Using the DataFID Battery Charger
READ THESE INSTRUCTIONS BEFORE USING THE CHARGER
The DataFID battery charger is only designed for indoor use
and should not come into contact with water or dust. In order to
avoid overheating, the charger should not be covered when it is
in use.
The charger is turned on by connecting it to the mains socket.
Disconnecting it from the mains socket turns the charger off. If
the charger is equipped with a mains cord, verify that the cord
has not been damaged. If the cord is damaged, the charger
must not be used.
The charger contains dangerous voltages and the cover should not be removed.
CHARGER FUNCTIONALITY
This charger is a fast charger for NiMH batteries. The charger will automatically charge the battery at a
fast rate, and then charge to a slow rate near the end of the cycle. This prevents over-charging.
CAUTION: Do not charge batteries at too high or too low temperatures. Charge only in areas between
38-110°F (3-43°C).
HOW TO USE THE CHARGER
The Charger is started by connecting the battery pack to the charger. Once connected, the indicator LED
will start Orange, for the Initialization and Analysis Phase, before switching to Red for the Fast Charge
Phase. When the batteries are fully charged, the charger will go into a top-off charge mode before it goes
over to trickle charge mode. During top-off charge, the LED will be Green with short intermittent Orange
light. When the top-off charge is completed, the charger will go into trickle charge mode and the LED will
be Green. The charge current is now reduced to a safe level, which allows the charger to stay connected
to the NiMH batteries without damaging the battery. If the battery voltage is far below normal, the charger
will cut off the fast charge current and go to trickle charge
mode. The LED will then indicate ‘error’ by
flickering Green and Red light. If the mains is turned off, the charger will reset and start a new charge
cycle if the mains is turned on again. If new batteries are to be connected, the charger must idle for
approximately 15 seconds to make sure all parameters in the microprocessor have been reset. The LED
changing to Orange light shows this and a new charge cycle can begin.
