About Exide Batteries
Take a battery tour to see why Exide batteries are market leaders or read below for further information.
The automotive battery provides starting power for the engine. It also supplies power to accessories such as lights, fans and radio when the engine is not running. Between low engine speeds and when accessory load is greater at higher running speeds, a battery makes up the difference by stabilising the alternator output. This stabilising effect also protects a vehicle’s electrical system by smoothing out sudden high voltages which can damage electrical components.
Batteries produce their power through a chemical reaction which is released when a load such as a globe, starter motor or electric fan is connected to the battery. Electrical current is generated when two different metals are placed separately in a liquid capable of conducting electricity. When the metals are connected together above the liquid, electrical current flows through the connection. The different metals are referred to as electrodes. Pure lead is used for the negative electrode or plate and a lead dioxide paste is used for the positive electrode.
The battery becomes discharged (or flat) when no more current flows through the cell. The cell can be recharged by forcing electrical current back through the cell in the reverse direction. The chemical reaction that takes place during discharge converts both the positive electrode and the negative electrode to lead sulphate. Water is produced and dilutes the strength of the acid. During recharge, the electrodes are converted back to lead dioxide and lead. The water produced during discharge is consumed returning the lead to its original strength. In addition, some electrolysis of the water in the electrolyte occurs breaking it down into its component gases: hydrogen and oxygen

The correct way to test a battery
Batteries must be subjected to regular testing to ensure their starting capacity is maintained at an optimum performance level. Visit your nearest Exide stockist for a professional battery check
A battery must also be scrutinised for any physical condition which may reduce battery life and impede starting performance such as broken or damaged posts and leaks to the battery case or lid.
The first step in evaluating starting capability involves testing a battery's state of charge using a hydrometer or voltmeter. All non-sealed batteries should be checked using a hydrometer.
As a cheap and reliable method of determining state of charge, the hydrometer also reveals differences between cells and allows visual inspection of the electrolyte colour.
Sealed batteries must produce a voltage of 12.5 or greater before a load test may be performed.
Since the loss/fail criteria varies depending on the make of load tester used, be sure to consult the instruction manual provided with the tester to ensure success.

Installing a Battery
Battery installation should only be undertaken by a professional installer and appropriate safety clothing must be worn at all times, including safety glasses.
Before charging begins, provide plenty of ventilation and ensure safety glasses or face shield are worn. Sparks from loose connections or metal tools making contact between the terminals or the undergrounded terminal and nearby grounded metal parts can also be hazardous. Do not remove the vent caps (maintainable product only) and do not charge the battery unless you are thouroughly familiar with the step-by-step procedure of recharging a battery. Ensure you have read the manufacturers instructions for the specific charger you are using prior to commencing the charging procedure.
Never touch the charger leads when the charger is ON. This could break a connection at the battery terminal and create a spark which could ignite the explosive gases in the battery. Never break a 'live' circuit at the battery terminal for the same reason. Always turn the charger OFF before removing a charger lead from the battery.
YOUR GUIDE TO BATTERY RECHARGING
The following charging rates and times assume a fully discharged condition.
Many chargers available will automatically adjust to discharged condition and commence ith a boost charge gradually changing to suit the battery condition and then switching off at the fully charged rate. If not an automatic switch mode charger use the above as a guide. Vew the range of Exide chargers available
Vehicle electrical and charging systems are becoming more complex and we recommend fitting by professional installers only. For more Help and advice (visit your nearest Exide store)

Correct Handling of batteries
Correct Storing of Batteries
Batteries have a limited shelf life and when stored gradually lose their power to perform. On average, a fully-charged battery takes about 13 weeks to gradually discharge to less than its optimum operating level.
The rate of charge loss depends on battery type (low maintenance or maintenance free) and temperature conditions.
Charge loss becomes more evident when temperatures increase. At 20°C low maintenance batteries lose approximately one half of one per cent of charge per day (30 percent in 60 days). At 30°C charge loss is usually double the rate for 20°C.
Under similar temperature conditions, maintenance free batteries lose their charge more slowly than low maintenance batteries. Excessive humidity will also accelerate charge loss.
A battery stored upright in cool and dry conditions is ideal.
Whilst in storage batteries that have not been recharged and allowed to go flat, may be permanently damaged. Recharging every four to eight weeks, depending on storage conditions, will restore batteries to "as new" condition.
It is best to trust Exide and its National network of reputable stores to deliver the optimal product that is professionally managed.
Do's and Don'ts
Deep Cycle Batteries
Why are they different
CAN YOUR DEEP CYCLE BATTERY BE USED FOR ENGINE STARTING?
Having established the number of Ampere Hours required, refer to the Deep Cycle Battery Specification listing to choose the correct battery for your needs. There is one further consideration. Battery capacity varies according to speed of discharge. The faster the battery is discharged, the fewer Ampere Hours it will deliver before requiring a recharge. Therefore, EXIDE Deep Cycle batteries are capacity rated for three lengths of discharge time. You will need to determine the length of time your battery will be discharged over and match to the closest rated discharge time quoted.
If being discharged over a 20 hour period, then a ED6 type will be very suitable.
If in doubt then please contact our professional store network or Exide Australia or New Zealand.
