Adler ADCHARGER 15 User manual

Features
–Charges with 12 V, 10/6/2 A DC (15/9/3 A RMS)
–Self-identifying multi-stage characteristic charging curve
Soft Start tests the battery condition. Severely discharged
batteries need the soft start step. The charging starts with a
reduced current until the voltage reaches 10V.
Bulk is the main step, where most of the charge is returned
(60-80%). The charger delivers maximum current until the
terminal voltage has risen to the set level of 14,2V for Normal
battery selection and 14.0V for Gel battery selection.
Absorption completes the charge up to virtually 100% at a
constant voltage. The current tapers off after the reaching the
minimum level.
Float is the maintenance charge at the constant voltage, keeping
the batteries at the 100% charge. The Normal charging mode is
time-limited (max 10 days) while the Supply mode goes on
indefinite without damaging the battery.
SPECIAL FEATURES
Temperature Control Fan
To protect the charger from overheating, a fan is included for heat
dispensation. Also to increase the life span of the fan, a sensor
will control the on off of the fan.
Temperature Compensation
A sensor will automatically adjust the charging voltage if the
temperature is between –20°C to +50°C. At a high temperature

environment the unit lowers the output voltage and at a freezing
condition, the unit adjusts a higher output voltage.
Voltage Compensation:
Because of some voltage drop in the cables, the actual voltage at
the clamps of the battery can be lower than the charger output
voltage. A special circuitry inside the unit will monitor the true input
voltage to the battery and adjust the output voltage of the unit
accordingly. This will maximize the charging efficiency.
Buzzer Warning
A built-in buzzer will help to warn the user if cables are connected
to the wrong clamps of the battery.
Display
Reverse Polarity - Reverse Polarity Connection to the
Battery Pole.
Battery Fault –Faulty Battery Indicator.
Charging –While Battery is Charging.
Full Charge –When Battery is Fully Charged and in
Maintenance Mode.
3 X 7 Segment LEDs Display for Charging Current, Battery
Voltage, & Charging %.
Cable Management
The casing is designed with an AC/DC cable storage
compartment. This will help to avoid cable damage and
subsequently any possible danger to the user.

Full protection against sparks
Short circuit protection
Voltage compensation
Overheating protection
Polarity reversal protection

IMPORTANT SAFETY INSTRUCTIONS
Gases
When the NORMAL/LEAD ACID battery is being charged you
may notice bubbling in the fluid caused by the release of gas. As
the gas is flammable, no naked lights should be used around the
battery.
The charging process must be performed in a well ventilated area.
Because of the risk of explosive gas, connect and disconnect the
battery leads only when the mains supply is disconnected.
Types of Batteries
This charger is only suitable for the specified batteries and should
not be used to recharge non-rechargeable, NICAD or any other
type of battery.
Point of Notes
When not in use, the battery charger must be kept in a dry area.
Keep away from any liquid, rain or snow.
This battery charger is not designed as a caravan lead-acid
battery charger or power supply.
This battery charger is not designed for installation on to the
vehicle as a fixture.
Danger
Avoid getting ELECTROLYTE on your skin or clothes. It is acidic
and can cause burns. If this occurs you shall rinse the affected
area with water immediately.
Never charge a frozen battery. If the battery fluid (electrolyte)
becomes frozen, bring the battery into a warm area to allow it to
thaw before charging. Never set a battery on a top of the charger
or vice versa.
Do not touch the battery clamps together when the charger is on.
Never operate the charger if it has received a hard blow, been
dropped, or otherwise damaged. Take it to a qualified professional
for inspection and repair.

Be sure to position the charger power cord to prevent it from
being stepped on, tripped over, or damaged.
Never pull out the plug by the cord when unplugging the charger.
Pulling on the cord may cause damage to the cord or the plug.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons.
PRE-CHARGE CHECKLIST
If the battery needs to be removed from the vehicle before
charging, always remove the grounded terminal from the battery
first, also ensure that all accessories in the vehicle are tuned off to
prevent arcing.
Make sure that the surrounding area is well ventilated to allow
dispersal of toxic fumes or gases.
Make sure the battery terminals are clean. If the battery has a
removable vent cap, top up each battery cell with distilled water to
the level recommended by the battery manufacturer, do not
overfill.
If the battery does not have caps, refer to the manufacturer’s
instructions regarding charging and charging rates.
OPERATING INSTRUCTIONS
Connection
1. Connect the DC Clamps to the battery poles in the following
order:
2. Connect the positive charging lead (RED) to the positive
terminal pole of the battery (marked P or +).
3. Connect the negative lead (BLACK) to the negative pole of the
battery (marked N or -).

4. It is important to ensure that both DC Clamps are in a good
contact with their respective terminal poles.
Control Panel
1. Charge Rate Button sets the charge rate to one of the
following:
2A DC Slow - Intended for charging small
batteries such as those commonly used in
garden tractors, snow mobiles and
motorcycles. The 2A rate is not intended
to be used as a trickle charger for larger
batteries.
6A DC Normal - Use for charging
automotive batteries, marine batteries,
and deep cycle batteries at a normal rate.
10A DC Fast - Use for charging
automotive batteries, marine batteries,
and deep cycle batteries at a fast rate.

2. Battery Selection Button sets the type of battery to be
charged to one of the following:
GEL CELL / SLA –All type of “gel cell” & “SLA” type battery.
Regular –All type of “lead acid” battery, sealed or non-seal.
3. Mode Display sets and shows one of the following reading:
Output current –shows selected charging current.
Battery voltage –shows voltage of the battery in DC.
Charging % –shows an estimate percentage of charge.
With the exception of gel cell and calcium batteries, all other
battery types may or may not have vent caps. Vent caps are
located on top of the battery and provide a means to add distilled
water when needed.
Batteries should be marked with their type. If charging a
battery that is not marked, check the manual of the item that
uses the battery. If the battery type is unknown, use the “Gel
Cell / SLA” setting.
Charging
Insert the AC plug into the mains supply (220-240 Volts AC only).

The battery charger is now in the stand-by mode with the default
choice of
Battery - “Gel Cell / SLA”
Current –“2A DC Slow”
If the Start Charging Button is now pressed, the charger will
immediately go into the 2A DC, Gel Cell battery charging mode.
For alternative selection, please follow the following steps:
Step1 –Press the Charge Rate Button to pick the battery
type for charging.
Step 2 –Press the Battery Selection Button to pick the
charging power.
Step 3 –Press the Start Charging Button to start the
charging process.
LED INDICATORS
On the front panel there are also 4 LED indicators for the following
functions:
1. Reverse Polarity –the DC Clamps have been connected at
the wrong pole on the battery. Simply disconnect and
reconnect the DC clamps at the correct pole, restart the
charging process.
2. Battery Fault –the battery can be broken. If the battery fault
display does not go off after resetting the charger, the battery
may be faulty. Please consult a nearby battery service centre.
3. Charging –the battery is in the charging process.
4. Full Charge –the battery is fully charged and the battery
charger is in maintenance mode.

COMPLETION OF CHARGING
When the battery “Full Charge” LED goes on, this mean the
battery is fully charged. The battery charger will now go into the
maintenance mode.
If the AC plug is pulled off from the mains supply, the battery
charger will turn off. The charging mode and status will be
recorded in the charger’s memory for 15min. Afterward it will reset
to the Standby mode. It helps to avoid any power failure, and
once power comes back, the charger will resume the charging
process at the previous mode.
If the DC clamps were pulled off from the battery while the AC
plug is still connected to the mains supply, the charger will
automatically switch back to the standby mode. Try to avoid
disconnecting the DC clamps while the AC socket is still
connected to power.
