MULTI 6
The MULTI 6 is designed for charging 4 to 8 NiCad & NIMH cells and 2 to 12 V lead-acid
batteries from a mains supply (230 V / 50 Hz). Battery capacity can be in the range 0.1 to 10
Amp/Hours (Ah). The unit provides six charge outputs with 6 different current ranges. Each
output is fitted with a LED which glows when charging is in progress.
All outputs are protected against short circuit, reversed polarity and overload.
Using the MULTI 6
The following six charge currents are available: 50 mA, 60 mA, 80 mA, 140 mA, 180 mA and
500 mA. The charge currents should be selected to match the capacity of the battery to be
charged. The standard rate is around 1/10th of the battery capacity indicated on the battery
pack.
Example:
Slow charge
Battery capacity = 500 mAh
500 mAh : 10 X 1,4 = 14h at 50 mAh
Fast charge
Battery capacity = 500 mAh
500 mAh X 1 X 1,1 = 66 min at 500 mAh
In our example the charge current should be 50 mA and the charge period 14 hours. These
figures apply to fully discharged packs. You should interrupt the charge process if:
1. The battery pack warms up, or
2. The lead/acid battery produces a slight, audible sissing noise
There is no danger of overcharging NC batteries if you keep to the 1/10 charge rate.
This means that you can safely recharge partially discharged packs for the full period
(up to 14 hours).
Note:
You can connect several NC packs to the MULTI 6 for simultaneous charging, but the total
charge current should not exceed 700 mA. For example, if you use the 500 mA output then
you can still use the 140 mA and one 60 mA output.
Connections and charging procedure:
First connect the charger to the mains supply (240 V / 50 Hz), then connect the charge lead
to the charger. Take care to maintain correct polarity (red = +; black = -).
The battery can now be connected to the charge lead. Please keep to this sequence as it
prevents the danger of short-circuiting the battery by allowing the banana plugs to touch.
If the connections are correct the LED above the charge output will light up, and the charge
process begins.
Caution: The charger does not switch itself off automatically. Disconnect the
battery or batteries when the charging period is over.

OPERATING INSTRUCTIONS
When a battery is fully charged, unplug the pack first, then the
charge lead, and finally – for safety's reasons – disconnect the
charger from the mains supply.
