TYT8117—UN—24MAY18
Standard
Used in cars, trucks, and motorcycles, these batteries
have vent caps and are often marked as low
maintenance or maintenance-free. This type of battery
is designed to deliver quick bursts of energy, such as for
starting engines, and has a greater plate count. The
plates are thinner and have different material
composition. Standard batteries should not be used for
deep-cycle applications.
TYT8116—UN—24MAY18
Absorbed Glass Mat
The absorbed glass mat (AGM) construction allows the
electrolyte to be suspended near the active material of
the plates. In theory, it enhances both the discharge and
recharge efciency. The AGM batteries are a variant of
sealed valve regulated lead-acid (VRLA) batteries.
Popular uses include high-performance engine starting,
power sports, deep-cycle, solar, and storage batteries.
TYT8115—UN—24MAY18
GEL
The electrolyte in a GEL cell has a silica additive that
Control Panel
15-2
causes it to set up or stiffen. The recharge voltages on
this type of cell are lower than other styles of the lead-
acid battery. It is probably the most sensitive cell in
terms of adverse reactions to overcharging. GEL
batteries are best used in very deep-cycle applications
and may last a bit longer in hot-weather applications. If
the wrong battery charger is used on a GEL cell battery,
poor performance and premature failure results.

Operating Instructions
It is important to fully assemble your charger before use.
Remove all cord wraps and uncoil the cables before
using the battery charger.
Charging the Battery
Keep in mind: when charging a battery, the more a
battery is discharged, the faster it absorbs charge from
the charger. In other words, it takes longer for the
battery to absorb the last few percents of charge than
the rst several percents.
CAUTION: Avoid injury or death from battery
explosions. When the start button is pressed in
either boost mode, charge/maintain mode, or
engine start mode, the clamps are energized
and spark if touched together. A spark near the
battery can cause an explosion. Make sure that
the charger is OFF before performing any
connection or disconnection operation.

Desulfation Mode
TYT8125—UN—23MAY18
Error Code
TYT8154—UN—18MAR20
Error Display
The display shows “SUL” when a sulfated battery is
detected and the charger goes into desulfation mode.
Desulfation could take 8 to 10 hours. If desulfation fails,
the display shows “F02”, charging aborts, and the bad
battery LED (red) illuminates.
Completion of Charge
TYT8119—UN—24MAY18
Charged/Maintaining
Charge completion is indicated by the charged/
maintainting LED (green). When lit, the charger has
switched to the maintain mode of operation.
Maintain Mode (Float Mode Monitoring)
TYT8119—UN—24MAY18
Charged/Maintaining
When the charged/maintaining LED (green) is
illuminated, the charger has started maintain mode. In
this mode, the charger keeps the battery fully charged
by delivering a small current when necessary. If the
charger has to provide its maximum maintain current for
a continuous 12 hours, it goes into abort mode. See
Aborted Charge section. This is caused by a drain on
the battery or the battery could be bad. Make sure that
there are no loads on the battery. If there are any loads,
remove them. If there no loads, have the battery
checked or replaced.
Maintaining A Battery
NOTE: The maintain mode technology allows the safe
charging and maintaining of a healthy battery for
extended periods of time. However, problems with
the battery, electrical problems in the vehicle,
improper connections, or other unanticipated
conditions could cause excessive current draws. As
such, occasionally monitoring your battery and the
charging process is required.
Operation
20-2
The TY27731 charges and maintains 6 V and 12 V
batteries, keeping them at a full charge.
Power-Up, Auto-Start
This charger is equipped with an auto-start feature that
triggers only when the charger is rst powered up. If the
START button is not pressed within 30 seconds, the unit
searches for a battery. If the unit detects a battery that is
properly connected, the unit sets the rate to boost,
battery type is set to AGM, it automatically starts the
charge process, and the ON LED (yellow/orange)
illuminates.
Using the Engine Start Feature
TYT8111—UN—24MAY18
Engine Start
If the battery is low, your battery charger can be used to
jump-start your car.
CAUTION: Follow the same safety instructions
and precautions as when charging the battery.
Wear complete eye protection and clothing
protection. Charge your battery in a well-
ventilated area.
IMPORTANT: Using the engine start feature without
a battery installed in the vehicle damages the
vehicle electrical system. Make sure that a
battery is installed to avoid damage.
NOTE: If the engine turns over but does not start, there
is not a problem with the starting system. There is a
problem somewhere else on the vehicle. Stop
cranking the engine until the other problem has
been diagnosed and corrected.
NOTE: During cold weather, or if the battery is under 2
volts, charge the battery for 5 minutes before using
the engine start feature.
IMPORTANT: If you have charged the battery and
engine still does not start, do not use the engine
start feature. Damage to the vehicle electrical
system occurs. Have the battery checked.
Engine Start Mode
1. Connect the charger to the battery and AC power.
TYT8111—UN—24MAY18
Engine Start Position
2. With the charger plugged in and connected to the
battery and chassis, press the rate selection button
until the engine start LED is illuminated, then press
the start button.
3. Crank the engine until it starts or crank for 7 seconds.
If the engine does not start, repeat. Do not crank
during the cool down period. The cool down period
allows the charger and the battery to cool down.
4. If the engine fails to start, charge the battery for 5
more minutes before attempting to crank the engine
again.
NOTE: After three minutes in engine start mode, the
charger will allow the charger and the battery to
cool down for 180 seconds. If the engine fails to
start, use the 50 A boost mode to charge the
battery for several minutes before attempting to
start the engine again.
5. After the engine starts, press the STOP button,
unplug the AC power cord, and disconnect the
battery clamps from the vehicle.
6. Clean and store the charger in a dry location.
Engine Starting Notes
During the starting sequence listed above, the charger
is set to one of 4 states:
● Wait for ready: The charger charges the battery for
2 minutes before the wait for cranking state. While
waiting for ready, the digital display shows and the
engine can be started. For severely discharged
batteries, it is not recommended to crank during this
time.
● Wait for cranking: The charger waits until the
engine is actually being cranked before delivering the
amps for engine start. While waiting for cranking, the
digital display shows “rdy”.
● Cranking:When cranking is detected, the charger
automatically delivers up to its maximum output, as
required by the starting system, for up to 7 seconds.
● Cool Down: After repeated cranking during a 3-
minute ready period, the charger enters a mandatory
3 minute (180 seconds) cool down state. The digital
display indicates the remaining cool down time in
seconds. It starts at 180 and counts down to zero.
After 3 minutes, the digital display will change from
displaying the countdown to displaying “rdy”. After 2
hours of engine starting, the unit will automatically

Maintenance and Care
A minimal amount of care can keep your battery charger
working properly for years.
● Clean the clamps each time you are nished
charging. Wipe off any battery uid that comes in
contact with the clamps to prevent corrosion.
● Occasionally cleaning the case of the charger with a
soft cloth keeps the nish shiny and help prevent
corrosion.
● Coil the input and output cords neatly when storing
the charger. This helps prevent accidental damage to
the cords and charger.
● Store the charger unplugged from the AC power
outlet in an upright position.
● Store inside, in a cool, dry place. Do not store the
clamps on the handle, clipped together, on or around
metal, or clipped to the cables.
