Replacing A Charging Pod
The charging pod is made from quality materials and designed to provide
years of service when properly used. In most cases, the charging pod will
only be replaced when you want to use the charger with a different battery.
Follow these steps to change the charging pod:
Obtain a charging pod made specifically for the ENDURA™ TWC1. Confirm
that the charging pod is compatible with the battery you want to charge.
Unplug the AC to DC power supply from the ENDURA™ TWC1.
Turn the locking screw on the bottom of the charging pod counter-clock-
wise several rotations. (The screw remains connected to the charging
pod.) Lift the charging pod from the charging base.
Insert the replacement charging pod into the charging base and secure
with the locking screw. Do not over tighten the screw.
Inspect the charging contacts to ensure they are clean and unobstructed.
Connect the AC to DC power supply to the ENDURA™ TWC1. You are now
ready to charge a battery compatible with the charging pod.

Charging A Battery
Confirm that the charging pod and battery are compatible.
Connect the DC end of the power supply to the DC plug on the back of the
charger, then connect the AC adaptor to a wall outlet (120V AC).
Place battery to be charged in the charging pod. The battery may be
charged while attached to the radio. Note: If the battery is attached to
radio, turn the radio off while in the charger.
When a battery is placed in the charging pod, the charge status LED will
illuminate ORANGE for a short period while the charger performs a battery
diagnostic. Once completed, the charge status LED will change to RED.
This indicates the battery is charging.
While a battery is charging, the charge status LED will illuminate RED
with no flashing. If the charge status LED is red and flashes, a fault has
been detected. The flash pattern represents a specific fault condition.
See section Fault Conditions for details.
When the battery is charged to 80% of capacity, the charge status LED will
change to GREEN and begin to flash. It is recommended that the battery be
charged to at least 80% capacity before use.
The charge status LED will illuminate GREEN with no flashing when the
battery is fully charged. Note: Remove battery from charger within 15
hours after charging is complete.
After removing a fully charged battery, the charge status LED may remain
illuminated for a few seconds. Allow the charge status LED to go off before
placing another battery in the charging pod.
The ENDURA™ TWC1 is designed to operate at room temperatures be-
tween 15°C and 30°C. Charging batteries at room temperatures outside
this range may result in under charging of batteries.
