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.

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.

OPERATING INSTRUCTIONS

Safety notes:

- Place the charger on a firm, level surface for charging.

- Do not cover the ventilation slots.

- Take care over battery polarity, and observe the manufacturer’s recommendations. Avoid
short circuits.

- NC cells become warm when charged. If the pack feels hot, disconnect the battery

- Be sure to set the correct charge current to suit the capacity of the NC pack.

- Do not exceed the recommended charge period.

- Always plug the charge lead into the charger first, then connect the battery.

- If the mains supply fails or you disconnect the mains plug, always disconnect any
batteries from the charger, as the may discharge themselves.

- If batteries are overcharged they become very hot. For this reason it is always best to
place the pack on an insulated, heat-resistant surface for charging.

- The charger must only be used in dry conditions.

Technical specifications:

Input voltage: 240 V / 50 Hz mains supply
No. of battery cells: 4 to 8 NC or NIMH cells

2-12 V lead/acid battery
Battery capacity: 0.1 to 10 Ah
Output currents: 50 mA, 60 mA, 80 mA, 140 mA, 180 mA and 500 mA

We reserve the right to alter technical specifications. We accept no liability for incorrect in­formation, printing errors, misuse of the charger and any damages caused by the unit.

MODE D’EMPLOI

Le chargeur MULTI 6 permet de charger de 4 à 8 éléments NiCad ou NIMH et des accus au
plomb de 2 à 12 volts avec une capacité de 0,1 à 10 ampère/heure (Ah) à partir du secteur
(240 V / 50 Hz). Six sorties de charge avec 6 gammes de courant sont à disposition pour la
charge des accus. Chaque sortie est munie d’une LED de contrôle qui s’allume pendant la
charge. Toutes les sorties sont protégées contre les courts-circuits, l’inversion de polarité et
les surcharges.

Charger avec le MULTI 6

Les six courants de charge suivant sont à disposition pour la charge d’accus : 50 mA, 60
mA, 80 mA, 140 mA, 180 mA and 500 mA. Le courant de charge dépend de la capacité de
l’accu à charger et doit s’élever à approximativement 1/10 de la capacité mentionnée sur
l’accu.

Exemple :
Charge lente
Capacité de la batterie = 500 mAh
500 mAh : 10 X 1,4 = 14h at 50 mAh
Charge rapide
Capacité de la batterie = 500 mAh
500 mAh X 1 X 1,1 = 66 min at 500 mAh

Dans cet exemple, le courant de charge est donc de 50 mA et la
durée de la charge de 14 heures. Ces indications concernent des
