Corrosion on the battery terminals is caused by electrolytes that have leaked from the battery and it has crystallised when it has met the air. To remove the corrosion form the battery use boiling water with bicarb soda and a wire brush. Put some bicarb soda in the boiling water and pour over terminals, scrub thoroughly with the wire brush to remove all corrosion.

The average life span of a battery is 3 to 5 years. So if your battery is of this age or you notice a reduction in cranking performance you should have the battery tested immediately by a qualified technician to find out what condition it is in.

Driving short distances does not allow the battery to be fully charged, so over time the batteries capacity can be reduced and in the worst case can cause sulphation which in turn can shorten the life of your car’s battery. A long drive can help the batteries health, though the best way is to periodically charge the battery on an appropriate battery charger.

Having the correct battery in your vehicle is vitally important for longevity and performance. The battery needs to have the right CCA and reserve capacity for starting and running your car, it also has to be held down properly as vibration is one of the biggest factors in batteries failing. The correct size and position of the terminals is also important when selecting the battery for your vehicle, as they can be in different positions and range from small to large.

The cost of replacing your car battery depends on several factors. The functionalities, engineering, and durability of the battery all play a role in the cost of a new battery.
The brand, the model and the type of battery you are replacing it with will also factor into the cost. On average the price of a new battery can range anywhere from
$100.00 to $500.00 depending on the vehicle make, model and the cost of installation.

This can be easily diagnosed by a qualified technician using the correct testing equipment. If you are unsure as to what is the condition of your battery and alternator call into SW Batteries and have them both tested correctly.

A car battery is the vehicles power bank. The box shaped battery stores the power needed to start the vehicles motor and run the car’s electrics and accessories when required.
