CONNECTIONS, CHARGING BATTERIES (NC / NIMH / LEAD-ACID)
• Fist connect the charger to the mains (230 V AC / 50 Hz), then plug the charge lead into
the appropriate charge output.
• Take care to maintain correct polarity (red = + / black = -).
• Lead-acid battery: set the nominal voltage using the switch adjacent to the charge
output.
• Only now connect the battery to the charge lead. This sequence reliably eliminates the
danger of short-circuiting the battery via the charge lead banana plugs.
• If the connection is correct, the LED above the charge output lights up, and the charge
process starts. If the "POWER" LED flashes, the battery is connected incorrectly:
disconnect the battery, unplug the charger from the mains, and start again.
• NC / NiMH batteries at output 3 are switched off automatically at the end of the charge
(Delta-Peak process), and the LED above the output flashes.
• The charge time for NC / NiMH batteries at output 4, 5
and 6 must be calculated (see charge currents, charge
time for NC / NiMH batteries).
• Lead-acid batteries at output 7 are automatically switched
off at the end of the charge (CC-CV process, and the LED
above the output flashes.
CHARGE CURRENTS, CHARGE TIMES FOR NC / NIMH BATTERIES
Caution:
Outputs 4, 5 and 6 are not switched off automatically! When the prescribed charge
time has elapsed, disconnect the battery from the charger to avoid the risk of fire.
Always disconnect the battery first, then unplug the charge lead, and finally disconnect the
charger from the mains.
The charge current varies according to the capacity of the NC / NiMH battery to be charged,
and should be in the range 0.1 - 1C. For example, if a battery with a capacity of 250 mAh is
to be charged at a rate of "1C", a current of 250 mA must flow.
Battery capacity (mAh) x 1.4 = charge time (hours)
Charge current (mA)
Example:
Receiver battery 4.8 V / 1200 mAh
Charge time: 1200 mAh x 1.4 = 14 h
120 mA
Our example gives a charge current of 120 mA and a charge time of 14 hours. These
recommendations apply to completely discharged batteries.
It is essential to stop the charge process early if:
1.) the NC / NiMH battery heats up to more than about 45°C, or
2.) you hear a quiet hissing from a lead-acid battery.
