Explosive mixtures of Hydrogen gas are
present within battery cells at all times. Do
not work with or charge battery in an area
where open flames (including gas furnace
or water heater pilots), sparks, cigarettes,
or any other sources of combustion are
present. Always provide ample ventilation
in rooms where batteries are being
charged. Failure to do so may result in
severe bodily injury and/or property
damage.
CHARGING YOUR VEHICLE
Battery electrolyte is poisonous and
dangerous. It contains sulfuric acid. Avoid
contact with skin eyes or clothing. Wear
rubber gloves and safety glasses while
servicing batteries. DO NOT INGEST! This
may result in severe bodily injury.
Signet Charger Operation, Model HB Series
The Signet ® HB series
chargers use a semi-
automatic charging system.
The charger will turn itself
ON when the AC power cord
is connected to the AC
power source and turn itself
OFF when the batteries are
fully charged. Refer to the data plate on the charger for
the voltage and type power required for the charger.
There is a series of LED’s on the faceplate of the charger
that serve two functions:
1. Status of charge. The LED’s will display an
approximate percent of charge during the charging
cycle. Refer to the table below.
2. Error condition. All three
LED’s flashing is an
indication of a charging
problem (charger will also
be beeping). Refer to the
Charger Troubleshooting
section for information on
error codes.

Signet Charger Operation, Model HBS series
The Signet
®
HBS series
chargers are fully automatic.
The charger will turn itself ON
when the AC power cord is
connected to the AC power
source and turn itself OFF
when the batteries are fully
charged. Once the charge
cycle is complete, the charger
will continue to monitor the
batteries. If the battery
voltage drops during storage, the charger will start a new
cycle to keep the batteries fully charged.
NOTE: If the charger restarts during a short time
period of storage, then it would be an
indication of faulty batteries.
Refer to the data plate on the charger for the voltage
and type power required for the charger.
There is a series of LED’s on the faceplate of the charger
that serve two functions:
1. Status of charge. The STATUS LED’s will display
an approximate percent of charge during the
charging cycle. Refer to the table below.
2. Error condition. The FAULT LED flashing is an
indication of a charging problem (charger may also
be beeping). Refer to the
Charger
Troubleshooting section for information on error
codes.
Typical Signet ® HBS
The key switch must be in the “OFF” position
when charging the batteries. Failure to turn
the key switch “OFF” may result in damage to
the vehicles electrical system.
