HOW TO
PROPERLY
CHARGE YOUR
TC7000/TC7150
B AT T ERY.
WARNING
ONLY REMOVE THE
BATTERY IN A SAFE AREA.
RUGGED AUTHORITY www.cord-ex.com

The TC7000/7150 battery uses long life lithium based cells, the
expected continuous runtime for a TC7000/7150 from a full charged
battery pack is 6 hours (this can fluctuate depending upon actual
usage parameters). Permanent damage can be caused to Lithium
battery packs if they go into a “deep discharge” state, TC7000/7150
uses a unique method to help prevent this occurring, but the correct
battery usage and charge procedure detailed below must be followed.
BACKGROUND
TC7000/7150 monitors battery status using a coulomb counting technique which measures
the amount of energy used by the camera rather than the actual status of the battery
itself. This is different from many other non-Intrinsically Safe devices and is a result of the
certification restrictions. In order for this technique to function correctly, the camera requires
a fully charged battery to be inserted.
To help prevent the battery going into deep discharge which can cause damage,
TC7000/7150 incorporates a backup shutdown timer. After 6 hours runtime, the camera shuts
down automatically at which point, the battery should be removed and recharged as soon as
is safely possible.
If a partially charged battery is inserted, the battery status indication on the camera screen
will be removed and the shutdown timer will timeout after 2 hours, this mode of operation
is not recommended and may cause result in the battery going into deep discharge which
renders the battery unsafe and in need of replacement*
Even with the camera powered off, the Intrinsically Safe safety circuits are still functioning;
helping to ensure the camera is in a safe state. The trade-off for this continuous safety is that
the battery is being drained even with the camera powered off, which can also lead to deep
discharge. As such, at the end of a working period, the battery must be safely removed from
the camera and placed on charge, never leave the battery in the camera overnight, even if the
camera is powered off.
WARNING. ONLY REMOVE THE BATTERY IN A SAFE AREA.
CAMERA OPERATION
ALWAYS ENSURE A FULLY CHARGED BATTERY IS INSERTED
INTO THE TC7000/7150 OR POOR RUNTIME AND/OR BATTERY
DAMAGE MAY OCCUR.
TC7000/7150 will prompt the user on initial camera power up, to confirm that a
fresh battery has been installed;
• If the user answered Yes, then the battery charge status indicator will be displayed as
normal showing a full charge and the six hour safety timer will start.
• If the user answers No, then the camera will display a second warning screen,
informing the user that the camera will allow power up, but this mode of operation is not
recommended and damaged caused may not be covered by the Warranty. If the user
continues the power up routine in this mode, the battery charge status indicator will not
be displayed as the camera has no method of measuring the charge and the six hour
safety timer will be reduced to two hours.
NOTE, this is not the preferred method of use for the camera and battery damage may
still occur.*
CHARGING THE BATTERY
1. Plug the charger into a wall socket/outlet. The Green LED will illuminate showing mains
power is connected and that the charger is ready.
2. Insert TC7000/7150 battery pack into the charging station. Care must be taken to
ensure that the battery is inserted in the correct orientation, otherwise battery and/
or charger damage may occur. If the battery is properly located in the charging station,
the Yellow LED on the charger will illuminate to indicate
charging. Once the charge cycle is complete, the
Yellow LED will extinguish.
3. If the Yellow LED flashes, this indicates a deep-
discharge or short circuit state. The battery
should be removed from the charging station
immediately and the troubleshooting guide
referred to.

TROUBLESHOOTING
WARRANTY STATEMENT (BATTERIES)
CorDEX Instruments Ltd, take great pride in the products we manufacture and warrant our
products including batteries to be free from manufacturer’s defects. If your battery fails, we
recommend the following: First, determine if the battery needs a boost or replacement. Most
batteries that fail are simply discharged and need a boost. If the battery is simply in need of
a boost, have it re-charged as described in this document. If your battery still fails, please
follow the troubleshooting guide above and then contact us at [e-mail] quoting
the battery voltage, the camera serial number and battery serial number along with your
complete contact details, including telephone number and email. Please note, batteries in
deep-discharge are not covered by Warranty.
* Deep discharge can only occur when a battery is left in the camera for an extended period which is contrary to correct
operation, subsequent damage is not covered by Warranty.
Problem Solution
My camera has poor runtime but
the battery status indicator on the
screen shows full.
When a new battery is inserted, the camera assumes the battery
is fully charged and shows a full charge on the screen. Insert a fully
charged battery into the camera.
My battery will not charge and will
not power up the camera.
Ensure the battery has not gone into “deep-discharge” by using a
multi-meter to check the voltage across the pads on the base of the
battery. If the reading is less than 6V then the battery has gone into
a deep discharge state and must be replaced. If the battery voltage is
above 6V then refer to the battery charging procedure and ensure the
charger LEDs are illuminating correctly.
My camera is unstable and
sometimes hangs.
Check the battery voltage by using a multi-meter across the battery
pads. If the battery has not been fully charged and/or has been
inserted into the camera partially charged, the cut off timer will not
operate and the battery voltage may drop below 6.9V at which stage
the camera may become unstable. Always ensure a fully charged
battery is inserted into the camera.
The battery charger is flashing
yellow.
This indicates either that the battery is short circuited or is in a deep
discharge state. In either event, the battery must be removed from
the charger and disposed of immediately.
WARNING. ONLY REMOVE THE BATTERY IN A SAFE AREA.
