Car Batteries

While car battery technology has changed over the years, the primary function of the battery hasn’t.  A battery provides a charge of electricity that is utilised by the starter motor and ignition system so the engine can turn over and start.  The battery then maintains a constant electrical charge to keep it going, along with any extra power required when a car’s electrical system needs are more than the alternator is capable of supplying.

The battery also acts as a voltage stabilizer in the electrical system and smooths out any transient voltages that may occur.  The battery also supplies power to items like the ECU, radio and clock when the vehicle is not being used.

Like any part in your car, your battery has a lifespan.  As batteries age they slowly lose capacity simply through general use.  In addition to this, electrical shorts can occur, components can corrode over time and vibration can also cause damage.  The average age of a passenger car battery is about 42 months. In addition to general age, the following issues can impact battery life:

• Accidentally leaving the lights on, including the interior lights
• Items like dash cams can also run down the battery when the car is off
• Lots of short trips can mean the battery doesn’t get the opportunity to recharge
• Vehicles sitting unused for long periods of time will shorten the battery life 

Having your battery tested regularly can save you a lot of time and hassle by identifying the potential life left in your car’s battery.

The short answer is no, you should only use a battery that is specially designed for your vehicle type and usage.
