4.1 Operation with NiMh Battery Pack 45-56

4.1.1 Battery notes

• The battery pack must be charged before it is used for the first time.
• The battery pack reaches its maximum capacity only after several char-
ge/discharge cycles.
• Avoid deep-discharging of the battery pack. Never attempt to fully dischar-
ge the battery pack (with a lamp or similar load). Deep-discharging may
destroy the battery pack.
• Rechargeable batteries discharge themselves gradually even if they are not
used. The self-discharge rate increases at higher ambient temperatures.
We therefore recommend that you store the battery pack at a temperature
of 2 °C to 8 ° C (e.g. in a refrigerator).
• Keep the battery pack charged and recharge it at suitable intervals.
• Protect the battery pack against frost and heat!

4.1.2 Connecting the charger to the mains

The charger is supplied complete with interchangeable adapters for different
mains sockets (Fig. 5). To change the adapter, disconnect the charger from
the mains socket, release the currently installed adapter by pressing the key a
and at the same time pull off the adapter y (Fig. 6).
With no adapter fitted, the battery charger can be connected to a mains
socket with the aid of a mains cable (not included) which is inserted into the
integrated mains connection socket (Fig. 7).

4.1.3 Charging the batteries

The NiMH battery pack 45-56 can be charged either in the flashgun or
3)
separately. If it is charged in the flashgun, the flashgun must be switched off !
DO NOT switch on the flash unit while the battery is being charged in
the flash unit! The battery must only be charged with the original Metz
battery charger envisaged for this purpose! DO NOT use any other
charger!
The battery pack is exhausted if the recharging time after a full-power flash
(e.g. in manual flash mode M) exceeds about 60 seconds.
3)
The charging operation is monitored by a microcontroller in the battery char-
ger. When the battery pack is fully charged, the charging operation is termi-
nated automatically and the battery charger switches to trickle-charge mode.
For safety reasons, the temperature of the battery pack is monitored during
charging and the charging time is also limited by a timer. The charging time
is about 2.5 hours for a fully discharged battery pack and correspondingly
shorter for a partially discharged battery pack.
• Connect the battery charger 970 to a mains outlet socket and to the
battery pack (the connector for the charger is on the bottom of the
pack). The charging operation starts automatically. The status of the
battery charger is indicated by a two-colour LED.
> LED lights with green light: The battery charger is connected to the
mains outlet socket but no battery pack to be charged is
connected.
> LED lights with red light: the battery pack is being charged.
> LED lights with red light: charging erro
- The battery pack has a short circuit.
- The battery pack is not connected correctly.
- The temperature of the battery pack is too low (<0°C).
- The temperature of the battery pack is too high (>40°C).
> LED lights with green light: the battery pack has been fully charged
and the charger has switched to trickle-charge mode.
Identifying a discharged battery pack 45-56
move the ribbed slide on the battery cover to the black position.
Identifying a fully charged battery pack 45-56
move the ribbed slide on the battery cover to the white position.
You can leave the battery pack connected to the charger in order to
ensure continuous readiness. However, if you do not intend to use
the battery pack for a long period, you should disconnect it from the
charger.
