TYPES OF BATTERIESThis 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 non-rechargeable batteries.

POINTS TO NOTEWhen 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.

DANGERThe 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.

CHARGING YOUR BATTERY Always charge in a well ventilated area!A)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 BATTERYFirstly 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.

1. CONNECTIONTo 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.

A) Connect the positive charging lead (RED) to the positive post of the battery (marked P or +)B) Connect the negative charging lead (BLACK) to the negative post of the battery (marked N

or -)C) 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.

2. CHARGINGInsert the mains plug into the mains supply (230 Volts AC only). Switch on. Your Battery Charger should now be working and the rate of charge will be shown on the ammeter fitted on the front of the charger. When a flat battery is initially connected to the Battery Charger the charging rate should build up quickly. As the battery becomes more charged the rate of charge will drop, this is normal. The charging current will never fall to zero as the charger will continue to give a small output even when the battery is fully charged.

WARNING! DO NOT ATTEMPT TO START THE VEHICLE WITH THE CHARGER CONNECTED. THIS MAY BLOW THE OUTPUT FUSE OR DAMAGE YOUR BATTERY CHARGER.

A charging time of no more than 10 hours is recommended at no more than 10% of the battery’s ampere hour capacity. i.e. 40 Ah battery should be charged at no more than 4 Amps. The battery charger is fitted with an internal, automatic thermal protection device, if the charger overheats due to overload, environment or for any other reason, charging will be interrupted, charging will restart automatically when the charger has cooled down.Note: With a fully charged or faulty battery, virtually no charge may register on the ammeter.

D) ELECTROLYTERegularly check the specific gravity of the liquid, using a hydrometer, until a reading of “Fully Charged” or 1,250 is reached.

E) WHEN CHARGING IS COMPLETEFor a battery still installed in the vehicle:Disconnect the charger from the mains supply first, then remove the chassis connection. Remove the battery connection last.

Otherwise: Disconnect the charger from the mains supply, then disconnect the crocodile clips from the battery terminal posts.

Inspect the liquid levels in each cell and top up if necessary, using the correct fluid. Now push home or tighten the caps. Any surplus fluid around the cell tops should be wiped off (this should be done with extreme care as it is acidic).If the battery has been removed for charging, replace it and re-connect the cables.

CAR BATTERY MAINTENANCEIt 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.

FAULTY CELLSBatteries are usually made with six cells. One 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. The battery will require replacement if one or more cells are faulty.

CAREIt is important to maintain the battery leads on a regular basis as loose or dirty connections on your battery terminals may prevent the vehicle from starting. Do this by removing the leads from the battery, cleaning the inside of each connector and the terminal posts on the battery. Smear the terminal posts with grease, replace the connectors and tighten firmly.

For standard lead acid batteries, but not maintenance free, it is essential to keep the Electrolyte level above the plates. NOTE, however that you should not overfill the battery, 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 NON SEALED LEAD ACID BATTERIESUsing a hydrometer, which can be purchased from most motor 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 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.

SIMPLE FAULTSA) If the charger fails to work:1. Switch off immediately at mains2. After switching off the mains supply, ensure that the crocodile clips are making good contact

with the correct terminal posts and the correct output voltage has been selected. Ensure that the leads are not damaged.

3. Switch mains supply on and check again.

B) If the charger still does not work:1) Switch off immediately at mains and disconnect the output leads from the battery.2) Check that the output fuse and the fuse in the mains plug are intact.3) Check to see that the positive and negative leads are connected to the correct terminals.
