We offer a selection of manufacturer-recommended batteries from budget to top of the range, so if you are looking to replace your car battery in Canberra then you have come to the right place.
All of our batteries come with a minimum 12 month guarantee, with some having a 3 or even 5 year guarantee.
Free Battery Test
In most cases batteries can be tested either on or off the vehicle, using the relevant testing equipment.
A free battery fitting service is available for the majority of vehicles.
Over the years we have saved hundreds of customers the expense of having to buy a new battery by having the experience to know the fundamental difference between a discharged and faulty battery. Often for a small fee we can loan the customer a battery whilst we recharge and check out their battery. This coupled with asking the relevant questions means that we can more often than not pinpoint the actual problem and advise the customer accordingly. We are one of the few battery companies in the country to offer this service, saving the customer the need to buy a new battery.
Why You Need a Good Battery for Reliable Cold Weather Starting
A good battery is essential for reliable starting, especially during cold weather because cold weather increases the cranking load on the battery. Oil gets thicker at low temperatures so it takes more amps to crank a cold engine when you try to start it. At 0 degrees F, the number of cranking amps it takes to start a cold engine may increase as much as 2X depending on the viscosity of the oil in the crankcase. The thicker the oil, the harder is it to crank the engine.
At the same time, cold temperatures also sap the battery's ability to supply amps. At 0 degrees F, most batteries can only deliver about 65% of their normal cranking amps. At -20 degrees, battery power is cut in half!
Car Battery Ratings
Before you can test or replace your car battery, you need to know something about battery ratings:
Cold Cranking Amps (CCA) This is the most common battery capacity rating. The rating is the number of amps the battery can deliver for 30 seconds at 0 degrees F. while maintaining post voltage of 7.2 Volts. For reliable cold weather starting, most vehicles require 400 to 600 cold cranking amps. Larger displacement engines require more cranking amps. Some batteries are rated up to 1000 CCA, but may sacrifice reserve capacity to achieve high short term outputs.
Cranking Amps (CA) This is a less meaningful rating. It is the same as CCA except it is measured at 32 degrees F. A battery's CA rating can be converted to CCA by dividing the number by 1.28 (Example: a CA rating of 500 amps becomes 390 CCA).
Reserve Capacity (RC) Think of this as the battery's staying power. This is the number of minutes the battery will deliver 25 amps and still maintain a post voltage of 10.5 Volts. The higher the reserve capacity rating, the longer the battery will last if the charging system fails.
*Amp Hour Rating (A/H) This rating is not used much any more. It measures low current draw for 20 hours while maintaining a minimum post voltage of 10.5 Volts at 70 degrees F. (Example: a drain of 3 amps for 20 hours = 60 A/H rating).
