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.

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.
