Read these instructions before operating this car battery charger and retain for future reference.
SAFETY:
1. GASES:
When the 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, and the area
should be kept well ventilated.
2. REVERSE POLARITY PROTECTION:
In order to protect the charger from anyone incorrectly connecting the positive lead to the
negative terminal or vice versa, the battery charger contains a temperature-sensitive PPTC
resettable fuse. In case the fuse breaks upon short circuit, overload or reverse polarity, the
charger will self-repair.
3. TYPES OF BATTERIES:
This charger is only suitable for lead acid batteries and should not be used to recharge any other
type of battery.
4. IMPORTANT:
When not in use, the battery charger must be kept in a dry area to avoid moisture damaging the
transformer.
Your battery charger is meant for INDOOR USE ONLY. Keep away from liquids at all times.
BATTERY CHARGER
12Volt 4Amp

The mains supply cord of this appliance cannot be replaced; if the cord is damaged, the
appliance should be discarded.
5. DANGER:
Avoid getting electrolyte on your skin or clothes. It is acidic and can cause burns. If this occurs
you should rinse the affected area with water immediately.
INSTRUCTIONS FOR USE:
1. CHARGING YOUR CAR BATTERY
It is essential to disconnect the battery from the car. This will avoid possible damage to the
alternator.
To avoid damage to the bodywork from possible spillage it is advisable to remove the battery
completely.
2. PREPARATION OF THE BATTERY
Firstly remove the caps from each cell and check that the level of liquid is sufficient in each cell.
If it is below the recommended level, top up with ionized, or distilled water.
UNDER NO CIRCUMSTANCES SHOULD TAP WATER BE USED.
The cell caps should not be replaced until charging is complete. This allows any gases formed
during charging to escape. It is inevitable that some minor escape of acid will occur during
charging.
If your battery is permanently sealed it is not necessary to carry out these checks.
3. CONNECTIONS
Connect the crocodile clips to the battery in the following order:
a) Connect the positive charging lead (RED) to the positive terminal post of the battery (marked
P or +).
b) Connect the negative lead (BLACK) to the negative post of the battery (marked N or -).
It is important to ensure that both crocodile clips are making good contact with their respective
terminal posts.
4. CHARGING
Insert the power plug into the mains supply. Your battery charger should now be charging and
the power LED (Red) and the charging LED (Yellow) on the front of the charger will be lit.
When a flat battery is initially connected to the battery charger the Full LED lamp should not be
lit. When the battery is fully charged the Full LED (green) will be lit.
N.B. If you have not connected the crocodile clips to the battery when you turn on the mains
power the “Full” lamp will light up. Similarly, if you disconnect the clips from the battery
without switching off the mains power, the lamp will stay lit. THIS IS NOT A FAULT. If you now
connect the clips to a battery the “Full” lamp will go out, unless the battery is fully charged.
PLEASE NOTE HOWEVER FOR REASONS OF SAFETY YOU SHOULD ALWAYS CONNECT AND
DISCONNECT THE CROCODILE CLIPS TO THE BATTERY WITH THE MAINS POWER OFF.

5. ELECTROLYTE
Regularly check the specific gravity of the liquid, using a hydrometer, until a reading of “Fully
charged” or 1.250 is reached. A charging time of no more than 10 hours is recommended for
batteries of 34-45 ampere hour’s capacity.
6. WHEN CHARGING IS COMPLETE
Switch off the mains supply, unplug the charger, and disconnect the leads from the battery
posts. Inspect the liquid levels in each cell and top up if necessary, using the correct fluid. Now
replace the caps. Any surplus fluid around the cell tops should be wiped off (this should be done
with extreme care as it may be acidic).
If the battery has been removed for charging, replace it and reconnect the cables.
CAR BATTERY MAINTENANCE
It is essential to keep your battery regularly charged up throughout the year, especially during the
winter months.
In the winter the effectiveness of your car battery is reduced by the cold. Oil is thick, engines are
difficult to start and the heater, windscreen wipers and lights are all draining power. It is at this
time that batteries have to be at peak power. If your battery is not regularly maintained and kept
fully charged, it can cause problems and a possible breakdown.
Listed are some helpful hints on how to keep your battery healthy in conjunction with your battery
charger.
FAULTY CELLS
Batteries are usually made with six cells. Any of these cells can deteriorate or get damaged. If after
several hours charging your battery is still flat, you should test the battery. Take hydrometer
readings from each cell in the battery. If one reading is lower than the others this could indicate a
faulty cell. If necessary, get a car electrician to check your battery. One faulty cell is enough to ruin
your battery and you should have it replaced.
CARE
Sometimes the battery may appear flat, but this could simply be dirty or loose connections on your
battery terminals. It is important to maintain the leads on a regular basis. Do this by removing the
leads from the battery, cleaning the inside of each connector and the terminal posts on the battery.
Coat the terminal posts with readily available gels for this purpose. Replace the connectors and
tighten firmly.
It is essential to keep the electrolyte level above the plates. However, you should not overfill it as
the electrolyte is strongly acidic.
When topping up DO NOT USE TAP WATER. Always use distilled or ionised water.
It is important to keep the acid level topped up, if necessary have it checked by your garage.
CHECKING THE CONDITION OF YOUR BATTERY
Using a hydrometer which can be purchased from most car accessory stores, you can check the
specific gravity of the electrolyte in each cell. The hydrometer is used to suck up a quantity of fluid

Car Battery Charger 11123 Instructions for Use
Please read and retain these instructions for future reference v001: 17/04/18
from the cell. The weighted float inside the hydrometer will register the condition of that cell. Put
the fluid back into the cell after testing, taking care not to splash the fluid about.
Always wash out the hydrometer after use.
FAQs
If the “POWER” LED fails to light:
Switch off immediately at the mains.
After switching off the mains supply, switch on and check again.
Ensure the leads are not damaged.
If the panel lights flicker and go out:
Switch off immediately at the mains.
Ensure that the output leads are not touching.
Check to see that the positive and negative leads are connected to the correct terminals.
Important Notice
If the “Power” and “Full” LEDs are illuminated and there is no output charge to your battery, please
check if your battery is defective.
