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 may have

come 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.

Troubleshooting

Problem Possible Cause Solution

Battery clamps do not spark when touched

together.

The charger is equipped with an auto-start

feature. It will not supply current to the battery

clamps until a battery is properly connected.

The clamps will not spark if touched together.

No problem; this is a normal condition.

The charger will not turn on when properly

connected.

AC outlet is dead. Check for open fuse or circuit breaker

supplying AC outlet.

Poor electrical connection. Check power cord and extension cord for the

loose tting plug.

Short or no start cycle when starting engine. No power at receptacle. Check for open fuse or circuit breaker

supplying AC outlet.

AC cord and/or extension cord is loose. Check power cord and extension cord for the

loose tting plug.

The clamps are not making a good

connection.

Check for poor connection at battery and

frame.

Failure to wait 3 minutes (180 seconds)

between cranks.

Wait 3 minutes of rest time before the next

crank to allow the battery and charger to cool

down.

The battery may be severely discharged.

10A BOOST

On a severely discharged battery, use the 10A

Boost setting for few minutes to help assist in

cranking.

The battery is drawing more than the Engine

Start Rate.

Crank time varies with the amount of current

drawn. If the cranking draws more than the

Engine Start Rate, crank time may be less

than 3 seconds.

The charger may be overheated. The thermal protector may have tripped and

needs a little longer to close. Make sure that

the charger vents are not blocked. Wait and

try again.

TYT8120—UN—24MAY18

RED LED

The red LED is lit.

The battery voltage is still below 10 V after 2

hours of charging. In maintain mode, the

output current is more than 1.5A for 12 hours.

The battery may be defective. Make sure that

there are no loads on the battery. If there are,

remove them. If there is none, have the

battery checked or replaced.

Desulfation was unsuccessful. The battery may be defective. Have battery

checked or replaced.

Lack of progress is detected and battery

voltage is below 14.2 V.

The battery may be overheated. If so, allow

the battery to cool. The battery may be too

large or have a short circuit. Have battery

checked or replaced.

The battery’s initial voltage is below 12.2 V

and the total input is less than 1.5 Ah.

The battery capacity is too low, or the battery

is too old. Have it checked or replaced.

The battery voltage drops to below 12.2 V in

Maintain Mode.

The battery won’t hold a charge. May be

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 remove them.

If there is none, have the battery checked or

replaced.
