ENDURA™ TWC12M

Introduction
Thank you for purchasing an ENDURA™ TWC12M, Twelve Unit Rapid Charger. This high
quality product is designed for charging two-way radio batteries whether on or off a radio.
Using six replaceable pods, the TWC12M can charge twelve batteries at the same time
and the batteries may be the same or different chemistries. Separate LEDs conrm the
charge status of each battery.
The six replaceable pods may be mixed. For example, six different pods could be installed
allowing two batteries for each of six different radio brands to be charged.
With the appropriate charging pod installed, TWC12M can charge these battery chem-
istries: lithium ion (Li-Ion), lithium polymer (LiPo), nickel-metal hydride (NiMH), or nickel
cadmium (NiCd). For a complete list of charging pods available for this charger, contact
your Power Products dealer or call customer service at 800-529-1618.

Important
1. Read all Caution statements below and this User Manual before attempting to charge
a battery.
2. Always charge new batteries completely before initial use. Recycle batteries when
they can no longer be used. Do not discard unwanted batteries in the trash or inciner-
ate. Batteries exposed to re or excessive heat may explode.
3. For best battery performance, charge NiCd and NiMH batteries when they are fully
discharged.
Caution
1. Never charge alkaline or dry cell batteries with this charger. Do not charge Li-Ion,
LiPo, NiMH, or NiCd batteries unless they are designed with overcharge protec-
tion.
2. Use charger in areas protected from the weather. Do not expose the charger to rain,
any liquids, or excessive moisture.

3. Do not attempt to charge a battery without rst installing the appropriate charging
pod. Use only charging pods designed for the ENDURA TWC12M charger. Disconnect
charger from power supply before installing, adjusting, or removing the charging pod.
4. Make sure contacts in charging pod and battery are clean. Do not allow wire or metal
objects to touch contacts in charging pod or any internal part of the charger.
5. Do not remove the charger’s housing or make any modication to the charger.
6. Use only the power supply provided with the ENDURA TWC12M charger. If a replace-
ment power supply is required, order part number TWC12M-PS. Use of other power
supplies may damage the charger or batteries you may be attempting to charge.

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. Each pod charges two batteries for a specic
radio; the two batteries may have different capacities or chemistries.
Follow these steps to change the charging pod:
1. Obtain a charging pod made specically for the TWC12M. Conrm that the charging pod is
compatible with the battery you want to charge.
2. Unplug the power supply from the TWC12M.
3. The charging pod is secured to the base with a single screw. Turn the locking screw on the bot-
tom of the rear charging pod counter-clockwise until it no longer holds the pod. Lift the charging
pod from the charging base.
4. Insert the replacement charging pod into the charging base and secure with the locking screw.
Do not over tighten the screw.
5. Inspect the charging contacts to ensure they are clean and unobstructed.
6. Connect the power supply to the TWC12M. You are now ready to charge a battery compatible
with the charging pod.

R - Status LED for rear position.
F - Status LED for front position.
P - Illuminates GREEN when TWC12M is connected to power.
Charging A Battery
1. Conrm that the charging pod and battery are compatible.
2. Insert the DC plug from the power supply into the opening on
the right side of TWC12M, connect the AC wall plug to a 120V
outlet, and turn the power switch (left side) to the on position.
The status LEDs marked “P” illuminate GREEN to conrm the
front and rear positions for each pod are receiving power.
3. Place the battery to be charged in either the front or rear posi-
tion of the charging pod. The status LED marked “F” or “R” will
illuminate to conrm which position is charging the battery. The
battery may be charged while attached to the radio and two
batteries may be charged simultaneously.

4. When a battery is placed in the charging pod and while charging, the charge status
LED (F or R) will illuminate RED with no ashing. If the charge status LED is red and
ashes, a fault has been detected. The ash pattern represents a specic fault condi-
tion. See section Fault Conditions for details.
5. When the battery is charged to 80% of capacity, the charge status LED will change to
GREEN and begin to ash. It is recommended that the battery be charged to at least
80% capacity before use.
6. The charge status LED will illuminate GREEN with no ashing when the battery is fully
charged.
7. After removing a fully charged battery, the charge status LED will illuminate ORANGE
for a few seconds. Allow the charge status LED to go off before placing another bat-
tery in the charging pod.
8. The TWC12M is designed to operate at room temperatures between 15°C and 30°C
(59° F – 86° F). Do not charge batteries at temperatures below 0°C (32° F) or above
45°C (113° F).

Fault Conditions
When the F or R charge status LED ashes RED, a fault condition exists. There are three
different ash patterns, each indicating a specic type of fault. The ash patterns and fault
conditions are as follows:
Flash Pattern Fault Type
Flashes 1 Time Indicates charging complete, but battery is under charged.
Battery voltage is below minimum level required. This warning is
provided after the rapid charging stage is complete.
Flashes 2 Times Indicates battery contact is “open” and current is not passing
through the (+) and (-) contacts on the battery. This warning is
provided after the initial diagnostic stage is complete. Check
charging pod to conrm compatibility with battery.
Flashes 3 Times Indicates over-current condition caused by battery short circuit.
Have the battery checked by a qualied technician. Do not
attempt charging the battery if a short circuit exists.
