ENDURA™EC12M

Introduction
Thank you for purchasing an ENDURA™ EC12M, 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 EC12M can charge twelve batteries at the same time and
the batteries may be the same or different chemistries. Separate LEDs confirm 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, EC12M can charge these battery chemistries:
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, visit www.powerproducts.com, 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 fire or excessive heat may explode.
3. For best battery performance, charge NiCd and NiMH batteries when they are fully
discharged.
Caution
1. Based on the pod selected, EC12M can charge Li-Ion / LiPo or NiMH / NiCd batteries.
If the pod is designed for Li-Ion / LiPo only, do not attempt to charge NiMH / NiCd
batteries. If the pod is designed for NiMH / NiCd only, do not attempt to charge Li-
Ion / LiPo batteries. Do not use EC12M to charge batteries with other chemistries or
batteries that do not have overcharge protection.
2. Use charger in areas protected from the weather. Do not expose the charger to rain,
any liquids, or excessive moisture.

CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER. NO
USER SERVICEABLE PARTS ARE INSIDE. REFER ANY SERVICING TO QUALIFIED SER-
VICE PERSONNEL.
The lightning flash and arrowhead within the triangle is a
warning sign alerting you of ‘dangerous voltage’ inside the
product.
3. Do not attempt to charge a battery without first installing the appropriate charging
pod. Use only charging pods designed for the EC12M charger. Disconnect charger
from power source before installing, adjusting, or removing the charging pod.
4. Make sure contacts in the 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 modification to the charger.
6. Use only the power supply provided with EC12M. If a replacement power sup-
ply is required, order part number TWC12M-PS. Use of other power sup-
plies may damage the charger or batteries you may be attempting to charge.
Caution (continued)

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 specific
radio; the two batteries may have different capacities or chemistries.
Follow these steps to change the charging pod:
1. Obtain a charging pod made specifically for the EC12M. Confirm that the charging pod is com-
patible with the battery you want to charge.
2. Unplug the power supply from the EC12M.
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 EC12M. 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 EC12M is connected to power.
Charging A Battery
1. Confirm 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 EC12M, connect the AC wall plug to a 120V out-
let, and turn the power switch (left side) to the on position. The
status LEDs marked “P” illuminate GREEN to confirm 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 confirm which position is charging the battery. The
battery may be charged while attached to the radio and two
batteries may be charged simultaneously.

9
Charging A Battery (continued)
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 flashing to indicate normal charging.
5. If the charge status LED is RED and flashes, a fault has been detected. The flash pat-
tern represents a specific fault condition. If the status LED is ORANGE (solid or flash-
ing), an advisement is being provided. See section Fault Conditions & Advisements.
6. 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.
7. The charge status LED will illuminate GREEN with no flashing when the battery is fully
charged.
8. 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
battery in the charging pod.
9. EC12M is designed to charge batteries with a temperature monitoring circuit when
the battery temperature is between 0°C and 45°C (32° F – 113° F); batteries outside
this temperature will not be charged. The ambient temperature should be 5°C - 40°C
(41° F - 104° F) while charging a battery.

10
Fault Conditions & Advisements
When the charge status LED flashes RED, a fault condition exists. A fault condition
requires immediate attention. When the status LED is solid or flashes ORANGE, you are
receiving an advisement about the battery.
The flash patterns for fault conditions are as follows:
LED Pattern Fault Description
Flashes RED
1 Time
Indicates (A) low voltage battery failure or (B) battery has a short circuit. If (A), the
battery’s voltage is below the minimum level required and cannot be charged. If
(B), the battery is defective and should be recycled. This warning is provided after
the pre-charge stage is completed.
Flashes RED
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 confirm compatibility with battery.
Flashes RED
3 Times
Battery temperature is 45°C (113° F) or above. Charging has terminated, remove
battery from charger. Have battery checked by a qualified technician.

11
Fault Conditions & Advisements (continued)
The flash patterns for advisements are as follows:
LED Pattern Advisement
Solid ORANGE
(Battery removed.)
Brief reset period for charger after battery is removed. Allow the LED to go off before
inserting another battery.
Solid ORANGE
(Battery inserted.)
Indicates battery is too cold when initially inserted. If the battery temperature is 0°C
(32° F) or below, charging is delayed for up to two hours. Battery is monitored and charging
resumes once it is above freezing. Monitoring terminates if the battery temperature remains
below freezing for two hours.
Flashes ORANGE
1 Time
Battery temperature remains at 0°C (32° F) or below after two hours of monitoring.
Remove battery from charger and allow it to warm.
Flashes ORANGE
2 Times
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.
