Introduction – EC6M Chargers
Thank you for purchasing an Endura™ EC6M charger. This User Manual covers two
models: EC6M and EC6M-V2. Both models are designed for desktop use, but may also
be installed in a vehicle with available accessories. The EC6M is compatible with
nearly all Endura TWP charging pods and for those pods that are not compatible, the
model EC6M-V2 is available. Feature differences for EC6M-V2 are noted in this manual
where appropriate.
The EC6M is designed for charging two-way radio batteries whether on or off a radio.
Based on the charging pod installed, it can rapid charge these battery chemistries:
lithium ion (Li-Ion), lithium polymer (LiPo), nickel-metal hydride (NiMH), or nickel
cadmium (NiCd).

If you wish to replace the charging pod in the future, check the model number on
the product label (EC6M or EC6M-V2) to ensure the replacement pod selected is
compatible with your model. For a complete list of charging pods available or to confirm
pod compatibility, contact a 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. Check to make sure a charging pod compatible with your battery is properly
installed before charging a battery or installing the charger in a vehicle.
3. 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 incinerate. Batteries exposed to fire or excessive heat may explode.
4. For best battery performance, charge NiCd and NiMH batteries when they are
fully discharged.

3
Caution
1. Based on the pod selected, EC6M can charge Li-Ion / LiPo / NiMH / NiCd batteries.
If the pod is marked for Li-Ion / LiPo only, do not attempt to charge NiMH / NiCd
batteries. If the pod is marked for NiMH / NiCd only, do not attempt to charge Li-
Ion / LiPo batteries. Do not use EC6M 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.
3. Do not attempt to charge a battery without first installing the appropriate charging
pod. Use only charging pods designed for your EC6M. Disconnect charger from
the power source before installing, adjusting, or removing the charging pod.
4. Make sure contacts in charging pod and on the battery are clean. Do not allow
wire or metal objects to touch contacts in charging pod or any internal part of the
charger.

4
Caution (continued)
5. Do not remove the charger’s housing or make any modification to the charger.
6. Use only the power supply or DC power accessories specified for EC6M. If a
replacement is required, see section EC6M Accessories. Use of other power
supplies or DC power accessories 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.
Follow these steps to change the charging pod:
1. Obtain a charging pod made specifically for EC6M or EC6M-V2. Confirm that the
charging pod is compatible with the battery you want to charge.
2. Unplug the charger from its power source.
3. The charging pod is secured to the base with a single screw. To remove, turn the
locking screw on the bottom of the 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 charger 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 or vehicle power adapter to the charger. You are now
ready to charge a battery compatible with the charging pod.

10
Charging A Battery
1. Confirm that the charging pod and battery are compatible.
2. Connect the charger to power with the power supply included.
3. Place the battery to be charged in the charging pod. The battery may also be
charged while attached to the radio.
4. When a battery is placed in the charging pod and while charging, the status LED
will illuminate RED with no flashing to indicate normal charging.
5. If the status LED is red and flashes, a fault has been detected. The flash pattern
represents a specific fault condition. If the status LED is orange (solid or flashing),
an advisement is being provided. See section Fault Conditions & Advisements for
details.
6. When the battery is charged to 80% of capacity, the 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.

11
Charging A Battery (Continued)
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. The EC6M 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. EC6M-V2 is designed to
charge batteries without a temperature monitoring circuit or with a temperature
monitoring circuit that is not compatible with EC6M and therefore cannot provide
cold and hot battery monitoring. For both EC6M and EC6M-V2, the ambient
temperature should be 5°C - 40°C (41° F - 104° F) while charging a battery.
10. To prevent battery damage, use EC6M-V2 to charge your battery: (A) when the
battery is above freezing (0°C / 32° F) or (B) when the battery is not excessively
warm to the touch (below 45°C / 113° F).
