Battery Type Button

Use this button to select the type of battery.

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 efciency. 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.

Aborted Charge

TYT8155—UN—19MAR20

Error Code

If charging cannot be completed normally, charging

aborts. When charging aborts, the charger output is

shut off and the display shows FNN (where nn is an

error code). See Troubleshooting for a description of the

error codes. Do not continue attempting to charge the

battery. Have it checked or replaced.

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.
