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.

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
