Ensure that cables are regularly inspected and kept in good condition.
Never use the battery charger if the mains lead or plug is damaged.
Never use the battery charger if the output leads or crocodile clips are damaged.
Never use the battery charger if it has been dropped or damaged in any way.
WARNING: Battery charging produces explosive gases. Prevent flames and sparks.
Provide adequate ventilation during charging.
Do not leave charging batteries unattended for long periods or overnight.
Do not operate the charger above its rated output for long periods.
Monitor charging to ensure that a decreasing level of charge is occurring.

Electrical repairs or replacement of the mains cable should only be carried out by the
manufacturer, its service agent or a suitably qualified electrician / electrical technician in
order to avoid a hazard.

GENERAL SAFETY

This battery charger can be used by children aged from 8 years and above, and persons
with reduced physical, sensory or mental capabilities or lack of experience and knowledge if
they have been given supervision or instruction concerning use of the appliance in a safe
way and understand the hazards involved. Children must not play with this battery charger.
Cleaning and user maintenance shall not be carried out by children without supervision.

TYPES OF BATTERIES

This charger is only suitable for Lead Acid batteries and should not be used to recharge
NICAD or any other type of battery. This charger must not be used to recharge non­rechargeable batteries.

POINTS TO NOTE

When not in use store the charger in a dry place to avoid moisture damage. Your Maypole
Battery Charger is suitable for INDOOR USE ONLY. Avoid exposure to rain or liquids at all
time. The Battery Charger should not be opened. Any attempt at modification or repair by
the user will result in the loss of our guarantee. Maintenance work should only be carried
out by a qualified electrical technician.

DANGER

The use of safety goggles and gloves when working with lead acid batteries is strongly
advised.
Avoid contact with the electrolyte as this is acidic and is likely to cause burns to the skin or
clothes. If this occurs you should rinse the affected area with plenty of water immediately. In
the event of burns to the skin, medical advice should be sought if the symptoms persist.

OPERATING INSTRUCTIONS - PLEASE READ CAREFULLY BEFORE USING

Please read the data on the front of this leaflet for the recommended battery capacities
suitable for use with this charger. Use with batteries smaller than this may lead to
overcharging and overheating of the battery.

A) PREPARATION

Always charge in a well ventilated area!
It is recommended that the battery is disconnected from the car when charging, as this will
prevent possible damage to the alternator. Please read your vehicle manufacturer’s
instructions for further information and advice.

B) PREPARATION OF THE BATTERY

Firstly remove the caps from each cell and check the level of liquid. If it is below the
recommended level, top up with ionised or distilled water. UNDER NO CIRCUMSTANCES
SHOULD TAP WATER BE USED

To avoid battery acid splashing, the cell caps should be replaced but not tightened 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 unnecessary to carry out these checks and
charging should be discontinued when the battery reaches a “gassing” voltage of 14.4V.

C) CONNECTION

To avoid sparks which could cause an explosion, the mains supply should be disconnected
before making or breaking battery connections.
Connect the crocodile clips to the battery in the following order.

1) Connect the positive charging lead (RED) to the positive post of the battery (marked P or
+)

2) Connect the negative charging lead (BLACK) to the negative post of the battery (marked
N or -)

3) If connecting to a battery which is still installed in the vehicle, the second connection
should be made to the chassis away from fuel lines, hot or moving parts

It is important to ensure that both crocodile clips are making good contact with their
respective terminal posts. The battery charger is fitted with an external, reverse polarity
protection fuse. If the leads are incorrectly connected the fuse will blow. Disconnect the
battery charger from the mains and battery before replacing the fuse. Make sure the
replacement fuse is of the same design and rating as the one removed.
