What is a battery? A device that produces electricity from a chemical reaction.
What does a battery consist of? Six cells, which each contain: Electrolyte Positive & negative plates Separators A positive & negative electrode
ALL ABOUT BATTERIES
5
Electrolyte:
A mixture of sulphuric acid and distilled water, which has been stripped of minerals and nutrients.
Fully charged battery has 36% acid & 64% water
Reacts chemically with the active materials on the plates
Creates an electrical pressure (voltage)
Conducts the electrical current produced by that pressure from plate to plate.
BATTERY COMPONENTS
6
Separators:
Thin, porous insulators
Made of woven glass or plastic envelopes
Placed between positive and negative plates
Allow passage of electrolyte
Prevent the plates from touching and shorting out
BATTERY COMPONENTS
7
Plates:
Flat, typically rectangular components that contain a mechanical support structure called a grid
Active material is pasted to the grid
Are either positive or negative, depending on the active material they hold.
Brown-coloured lead dioxide on the positive plates
Grey-coloured sponge lead on the negative plates
BATTERY COMPONENTS

Proper care of a battery is essential to its longevityBe sure to check your battery monthly for the following:
Dirt
Loose or corroded terminals
Cracked cell cover or case
Frayed or broken cables
Remember! A clean and well-maintained battery always lasts longer than a neglected one.
GENERAL MAINTENANCE
11
Batteries are very often damaged and destroyed through constant vibration and severe impact.
Avoid this by checking for the following:Deteriorated battery cablesLoose or slack connections between the terminals and polesCracked or broken battery trayLoose or defective battery hold-down clampCorroded battery hold down clampMisfit battery too small or too large
Where applicable, make repairs immediately!
NEVER hammer or shove terminals onto poles this is sure to drastically decrease the life of the battery.GENERAL MAINTENANCE

15
Characteristics of an AGM Battery:
Allows for extremely deep discharges, of up to 80%, without being damaged.
Has a charging rate that is five times faster than that of a flooded lead acid battery!
Extreme vibration protection resists vibration damage for better performance and longer life.
Tough, stainless steel terminals prevent corrosion for more power and better performance.AGM BATTERIES
16
A tool used to measure the state of charge of the battery, via the specific gravity
Specific gravity = exact weight
Hydrometer compares exact weight of electrolyte with that of water.
Each cell in a fully charged battery has a specific gravity of 1.265 or a voltage of 2.10.HYDROMETER
17
Several Battery Capacity Ratings have been established to determine the current capacity of a battery.
The current capacity is an indication of the batterys ability to develop and deliver high amperage current to the starter, and provide reserve power to the electrical system.
Some commonly used ratings are:-
Cold Cranking AmpsCranking AmpsHot Cranking AmpsReserve CapacityAmpere Hours
CAAhHCACCARCCAPACITY RATINGS
COLD CRANKING AMPS (CCA)
This rating indicates the batterys ability to deliver a specified current at low temperature.
It is determined by the amount of current a fully charged battery can supply for thirty (30) seconds at 0 F without the voltage falling below 7.2V.
CAAhHCACCARCCAPACITY RATINGS
CRANKING AMPS (CA)
This rating indicates the batterys ability to deliver cranking current at 32 F.
To convert CCA to CA, multiply the Cold Cranking Amps by 1.25.
For example, 650 CCA x 1.25 = 812 CA
CAAhHCACCARCCAPACITY RATINGS
HOT CRANKING AMPS (HCA)
This rating indicates the batterys ability to deliver cranking current at 80 F.
To convert CCA to HCA, multiply the Cold Cranking Amps by 1.5.
For example, 650 CCA x 1.5 = 975 HCA
CAAhHCACCARCCAPACITY RATINGS
RESERVE CAPACITY (RC)
This is the time in minutes that a vehicle can be driven after the charging system fails.
The assumed battery load is a constant discharge current of 25 Amps.
The Reserve Capacity is the length of time a fully charged battery at 80 F can supply 25 Amps before the voltage falls below 10.5 V.
CAAhHCACCARCCAPACITY RATINGS
AMPERE HOURS (Ah)
This is the amount of current a fully charged battery can supply for 20 hours without the voltage falling below 10.5 V at 80 F.
For example, if a battery can deliver 4 Amps under these conditions, it is an 80 Ah battery.
4 Amps x 20 Hours = 80 Ah.

CLEANING A BATTERY
24
Reminders:
Wash away dirt and residue from positive and negative terminals.
Use a solution of baking soda and water to neutralise corrosion.
Dry with a clean rag.
Reconnect the terminals to the battery, replacing the positive cable first and the negative cable last.
Replace/Repair damaged and deteriorated items.
Spray battery terminals with a solvent-free rust retardant, such as Fluid Film, to protect against rust and corrosion.

CHANGING A BATTERY
26
Ensure you have the correct battery for your vehicle by measuring the dimensions of the tray in which the battery sits, including width, length and depth.
Make certain the hand brake is up, the engine is switched off and the keys are out of the ignition.
Disconnect the negative connector first and then the positive connector. Reconnect in the opposite sequence.
Ensure the terminals and posts are clean and all tightening devices, such as nuts and bolts are in sound working order.
Before re-fitting the clamp and lid, try turning on the vehicle to make sure the battery is correctly inserted.
Once clamp is refitted, ensure the battery is secured properly and there is no sign of movement.
CHANGING A BATTERY
27
Storing a Battery Safely:
Disconnect the battery cables negative (black) first and positive (red) last.
Inspect battery, conducting general maintenance checks.
Check the electrolyte level in each cell, if it is a serviceable battery.
Refill where necessary with distilled water.
Remove the battery from the vehicle.
Store it in a cool, dry location, out of direct sunlight, elevated at least 12 inches off of the ground.
STORAGE OF BATTERIES
28
Storing a Battery Safely:
Ensure the battery is fully charged when storing.
Where possible, a smart or float charger should be used, to maintain the charge during storage.
For extended storage, a battery needs to be checked monthly to ensure charge isnt being extensively depleted.
Recharge as needed.
Batteries stored in a partially discharged state will self-destruct.
STORAGE OF BATTERIES
29
Using the correct method of charging a battery is essential to its longevity.
Both too much or too little charging can be disastrous to the battery and result in a shorter life.
Batteries should be tested regularly to ensure they are being correctly charged and are running at the proper amount of voltage.
CHARGING A BATTERY
30
Batteries can easily be under-charged. Having to frequently jump-start a battery signifies inferior charging. This can be a result of any of the following:
Damaged or Frayed Battery Cables Dirt or Corrosion on Battery Terminals and Poles Slack Terminals Cracked Battery Case Defective Alternator : Inspect the alternator or serpentine belts to be sure they are properly tensioned.
They should move less than an inch from their resting place.
If they are torn, cracked or frayed, they should be replaced.UNDER-CHARGING BATTERIES
31
Constant over-charging of a battery will rapidly destroy it. Batteries that have been over-charged can be identified by the following traits:
Swollen case Strong odourTwisted or deformed shape
How to check your battery for overcharging:
Start your vehicle.
Ensure the engine is running at a fast idle.
Measure the voltage that runs through the battery terminals.
It should be between 12.8V and 14.7V. Anything higher than 14.7V indicates overcharging in the battery.
Also measure the alternator voltage, which should be between 12.8V and 14.7V as well.OVER-CHARGING BATTERIES
32
Avoid over-charging by:
Having your alternator checked regularly by a mechanic to make sure it is operating efficiently. Malfunctioning alternators often send too much voltage to the battery, causing overcharging.
Conducting a battery load test on your battery every six months.
Using a modern battery charger if you need to charge the battery, as these will shut off before the battery becomes overcharged while older models may not have this safety feature.
OVER-CHARGING BATTERIES
33
Before jump-starting a battery, ensure the following criteria is met:
No signs of damage to the batteryNo loose or slack terminalsAll electrical devices are offLightsAir ConditionerWipersRadioThe vehicle is in neutral (manual) or park (automatic)The handbrake is engaged
When jump-starting, always use power from a battery with the same voltage, usually 12 volt.
After the engine has started, leave the vehicle running for some time to build up charge in the battery, before turning off.
JUMP-STARTING BATTERIES
34

Discharge a battery any deeper than you possibly have to.
Mix sizes and types of batteries.
Allow slack connections.
Smoke around a battery.
Hammer or shove terminals onto battery poles.BATTERY DONTS
37
When do I need to replace my battery?
Battery replacement may be necessary if you experience any of the following: Loss of power in cold or extended startsSlow or interrupted turnover of the starting motorBattery discharge light on the vehicle instrument panel is litCracks or other obvious damage to battery case
If you are experiencing any of these symptoms, you should have your battery and electrical system checked.
Why are slack or loose connections between terminals and poles so destructive to a battery?
Loose connections cause an electrical arching effect This destroys and damages battery poles and terminalsCan also cause damage to the electrical system and alternator.FREQUENTLY-ASKED QUESTIONS
38
How does excessive heat affect my battery?
Heat increases the rate of evaporationThis causes a loss of water from the electrolyteExtreme heat also increases the rate of self-discharge and promotes the corrosion of the positive plate grids. Heat is the number one killer of a batteryIt may increase performance in the short-term, but battery life is drastically reduced over time.
What characteristics should I look for in a battery?
Characteristics of a reliable battery: Maintenance Free Heat Resistant Vibration Resistant High Cranking Amps Warranty on both gas and diesel vehiclesFREQUENTLY-ASKED QUESTIONS
39
FREQUENTLY-ASKED QUESTIONSWhat causes a battery to explode?
Batteries contain sulphuric acid electrolyteThis is a highly corrosive substance that produces gases When ignited, it will explode. Explosions could result from the following:
Metal objects, such as rings, watch straps or hand tools brushing the battery and creating a spark
Jump-starting a battery that is leaking
Having smoke or naked flames near batteries which could ignite the gases released.
