2-3 CHARGING BATTERIES
Step 1. With the appropriate battery adapter installed, insert the first battery to be
charged in the Port-1 Channel-A battery location. Insure the battery is fully
seated into the adapter. Observe that CHARGE LED (amber) for the
corresponding location is lit or blinking rapidly. The CHARGE LED for the B
battery location will continue to blink if it is searching for a battery on that
channel. If the FAULT LED (red) is lit, the battery or adapter may be
defective. Check by removing battery and adapter. Then reinstall adapter
and battery. If the FAULT LED again lights, go to the Trouble Shooting
section of this Guide.
Step 2. Install the next battery into the Port-1 Channel-B battery location.
Step 3. Install the rest of the batteries. The indicators for these batteries will not
light until the charger has finished the batteries in the preceding Port
locations.
Step 4. After fast charging is complete, the CHARGE LED extinguishes and the
READY LED is lit. After the charger cycles through the batteries, it will top-
off batteries that have completed fast charge. The battery is slow-charged to
full capacity, as indicated by the blinking READY LED (green). The battery is
charged for five minutes at a time (10 minutes for dual section batteries)
then the charger will move on to the next battery. For Lithium type batteries,
the cycle will stop after the battery is 100% charged. For other types the
cycle is repeated indefinitely to keep the battery at 100% charge. As long as
the READY LED is lit (blinking or solid) the battery may be removed and
returned to service and another battery may be installed for charging.
NOTE
Battery charger power may be left ON while batteries and/or adapters
are removed or replaced. Batteries may be left in the charger for long
periods of time without damaging the batteries or charger.
2-4 BATTERY REVITALIZATION AND DESTORAGE
The procedures outlined below describe the means of invoking the Revitalization and
Destorage functions of the ALT 170C Charger as well as the sequence of operations
the charger will execute to perform the commanded tasks.
a. NiCad Revitalization (ALI 116 and ALI 124) – requires BTA-70589 Adapter
Revitalization exists on PORT 1 and is available for both the A and B channels of the
ALT 170C Charger. Due to the increased power dissipation from discharging the
batteries, this function will not operate above 40º C. The following procedure is used
to invoke the Revitalization process:
