TYT8117—UN—24MAY18

STD

Used in cars, trucks, and motorcycles, these batteries

have vent caps and are often marked "low

maintenance" or "maintenance-free". This type of

battery is designed to deliver quick bursts of energy

(such as starting engines) and has a greater plate

count. The plates are thinner and have dierent material

composition. Standard batteries should not be used for

deep-cycle applications.

TYT8116—UN—24MAY18

ABSORBED GLASS MAT

The Absorbed Glass Mat construction allows the

electrolyte to be suspended near the active material of

the plates. In theory, this enhances both the discharge

Control Panel

15-2

and recharge eciency. The AGM batteries are a

variant of Sealed VRLA (valve regulated lead-acid)

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

causes it to set up or stien. The recharge voltages on

this type of cell are lower than those for other styles of

the lead-acid battery. This is probably the most sensitive

cell in terms of adverse reactions to the over voltage

charging. Gel batteries are best used in VERY deep-

cycle application 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.

precautions for charging your battery. Wear complete

eye protection and protective clothing.

IMPORTANT: Using the ENGINE START feature

WITHOUT a battery installed in the vehicle

damages the vehicle’s electrical system.

NOTE: During cold weather, or if the battery is under 2

volts, boost the battery for 5 minutes before starting

the engine.

NOTE: If you have charged the battery and it still will not

start your car, do not use the ENGINE/START

feature, as it damages the vehicle’s electrical

system. Have the battery checked.

1. Set the switch to the OFF position.

2. With the charger unplugged from the AC outlet,

connect the charger to the battery while following the

instructions given in Charging a Battery in the Vehicle

CHARGED/MAINTAINING (green) LED

Charge completion is indicated by the CHARGED/

MAINTAINING (green) LED. When lit, the charger has

switched to the maintain mode of operation.

Maintain Mode (Float Mode Monitoring)

TYT8119—UN—24MAY18

CHARGED/MAINTAINING (green) LED

When the CHARGED/MAINTAINING (green) LED is lit,

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-hour period, it goes into the abort mode (see Aborted

Charge in this 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, remove

them. If there is none, have the battery checked or

replaced.

Operation

Maintaining a Battery

The TY27732 charges and maintains 6- and 12-V

batteries to keep them at a full charge.

NOTE: The maintain mode allows a healthy battery to

be safely charged and maintain for an extended

period of time. However, problems with the battery,

electrical problems in the vehicle, improper

connections, or other conditions could cause

excessive current draws. Monitoring your battery

and the charging process is required.

Fan Operation

It is normal for the fan to be on for a while after ENGINE

START operation to allow the charger to cool down. To

allow the fan to operate eciently, keep the area near

the charger clear of obstructions.
