Quick Reference
•Connect (or Disconnect) a battery only when the charger is either
unplugged from AC (off) or when the display indicates “-not
charging-“.
•For proper polarity connect the Positive (Red / +) charging cable to
the Positive terminal on the battery. Connect the Negative (Black /
-) charging cable to the Negative terminal on the battery.
Reversing these connections will result in the charger displaying a
“Reverse Polarity” error.
•When not charging, the charger screen looks similar to the
illustration shown on the right. The screen is organized in 6 sections as denoted by letters A-F:
•Battery Voltage and Battery Current shown in Screen Section E: this information is shown in
all modes and updates continuously.
▪Indicated Voltage will be 00.0V when a battery is not connected; or will reflect the
voltage of a connected battery.
▪Indicated Amperage will be 00.0A
•Charger Operational Status shown in Screen Section F: indicates whether the charger is “not
charging” and idle, or if a charge cycle is in process.
•Charger Voltage mode: User selects charger voltage for 12V or 24V operation as appropriate
for the battery to be charged by pressing the button in Screen Section A.
▪Caution: If a 12V battery is charged with a 24V charge curve the battery may be
overcharged causing potentially serious damage.
▪Caution: if a 24V battery is charged with a 12V charge curve the battery may be
undercharged, potentially damaging the battery. Please refer to the LT batteries CMM,
Section 5.1.2, 5.1.3, and section 5.1.4 page 11.
•Charger Current mode: User selects for 6A to 1A as appropriate for the battery to be charged
by pressing the button in Screen Section B.
▪Caution: Always follow battery Component Maintenance Manual (CMM) guidance.
•Charge Cycle End Condition: User selects amperage or time limited charge by pressing the
button in Screen Section C.
▪Amperage (.5A) –the charger will follow a three-stage charge mode recommended for
use with all normally discharged lead-acid batteries.
The final stage of the three-stage mode is a constant float maintenance charge. The
battery may be left on constant float and will maintain charge until use.
▪Time-Limited (65 hours to 10 hours) –the charger will follow a two-stage charge mode
recommended for use with deeply discharged or sulphated lead-acid batteries. Follow
CMM and see guidance (section 6) for calculating the recommended time limit.
•Go! Button: User initiated charge cycle
▪After confirming charger configuration, press the button in Screen Section D to start the
charge cycle.

•Quick Start
•Plug in charger, ensure charger shows “not Charging” in Idle Screen Section F.
•Connect battery, verify voltage in Section E has changed.
•Select Charge Voltage (Press button in Screen Section A), Charge Current (Screen Section B)
and Charge Cycle End Condition (Press button in Screen Section C).
•Press Go! (Press button in Screen Section D)
•Screen Section F will show “Charge Complete” when the charge cycle ends successfully.
Product Description
The Teledyne Battery Products TDMC+ is a battery charger for 12V and 24V lead-acid batteries. It
offers two microprocessor-controlled precision charging method: a three-stage charging method for
normally discharged batteries, and a two-stage charging Method for recovering sulphated or overly
discharged batteries.
The charger offers an internationally recognized AC input connector, wide input voltage range
operation, wide operating temperature operation, a sealed chassis with external convection-cooled
heat fins, reverse polarity detection, temperature and voltage protection and integrated voltage and
current monitor. The TDMC includes a battery connection cable with crocodile clips for a wide variety
of battery terminals.

Precautions and Warnings
Batteries
•Use caution when handling or charging batteries
•Use caution when charging at high current; monitor the battery regularly for overheating during
high current charging. Stop charging if the battery temperature exceeds 120F (50C).
Allow battery to cool to room temperature before restarting. Any battery that overheats has an
internal fault and should be rejected and recycled.
•Wear eye protection when handling, cleaning, working around, or charging batteries
•Verify that the battery rating corresponds to the charger output voltage setting, i.e. 12V to 12V,
24V to 24V
•Ensure the charger is “not charging” or off when making or breaking a battery connection.
•Never charge a battery that is, or appears to be: cracked, damaged, swollen, frozen, emitting a
strange odor, or leaking.
•Clean battery terminals. When cleaning, be careful to prevent corrosion from coming in contact
with eyes.
•Never short the terminals of a battery.
Location
•Use charger in a well-ventilated area: Lead-Acid batteries under charge may emit hydrogen gas.
•Remove battery from airplane before connecting charger.
•Place charger and battery on a smooth, even, uncluttered surface.
•Allow adequate airflow around the unit during charging to prevent overheating.
•Maintain minimum 3” (7cm) distance to wall
•Do not use the charger on a soft, carpeted, upholstered, or varnished surface
•Do not mount charger directly over, or directly under a charging battery.
•Use charger indoors only: the unit is closed to external airflow but not sealed, do not expose the
battery charger to water, snow, ice, moisture, fuel, oils, pressurized gasses, combustible or
inflammable substances.
•Only use in an area where all charger electrical cords will avoid hot surfaces, such as exhaust
pipes, and moving parts, such as fan wheels.
•Place the battery in a location where items will not be dropped on it.
•This charger can be used with Lead-Acid batteries only. Avoid charging batteries of differing
chemistries in the same work area in order to prevent accidental connection of charger to any
chemistry other than Lead-Acid.
Grounding and AC Power Cord
•Never use a cable that is worn, frayed or damaged.
•The battery charger must be grounded to reduce risk of electric shock. The charger must use an
electrical cord with a grounding plug. The outlet must be properly installed and grounded in
accordance with applicable codes and ordinances.
•Never connect the AC plug into an electrical outlet if you are wet or barefoot.
•DANGER –Never alter the AC cord or plug- if it will not fit in the outlet, have a proper outlet
installed by a qualified electrician.
