School Pick Up Zones Are Harming Your Car Battery: Experts Reveal Hidden Costs
Australians waiting in school pick-up zones with the engine off while running air conditioning could be shortening their car battery's lifespan, battery experts warn.
The daily school pick-up around Australia sees hundreds of cars converging on school zones with parents often arriving well before pick-up times.
But the idling engines running air conditioning, charging phones and listening to the radio will be draining the car battery without replenishing it.
Battery World's national product manager Seb Keane says the habit of using power accessories in stationary cars is one of the most common battery killers he encountered during his years as a roadside assistant.
“We see this all the time with parents during school pick-ups, people watching sports events from their cars, or camping with the power running. They don't realise they're giving their battery an early death sentence,” he said.
He said the problem is compounded by short trips, which don't allow the alternator enough time to recharge the battery after starting the engine.
And while many modern models turn themselves off while idling, parents are often forced to turn on the air conditioning in hot Australian weather.
“If you're only driving 5-10 minutes to school to sit idling for another chunk of time, the alternator can't replace the charge used to start the car. The maths simply doesn't add up – you're using more battery power than you're replenishing," Mr Keane said.
Research shows that with proper maintenance and care, car batteries should provide 3-5 years of reliable service. However, poor habits can, and often, dramatically shorten this lifespan.
Nine tips to extend battery life
- Take longer drives regularly – aim for 1-2 hours every few weeks to allow proper recharging
- Keep vehicles moving – don't leave cars idle for extended periods, especially with work-from-home arrangements
- Never use power accessories when the engine is off
- Charge the battery monthly with an appropriate battery charger
- Clean terminals and remove corrosion regularly
- Ensure the battery is securely mounted
- Minimise exposure to extreme temperatures where possible
- Maintain regular vehicle servicing schedules

“Many people think ‘maintenance-free’ batteries don't need any attention, but even these will benefit from regular care,” Mr Keane said.
“My number one tip is to hook your car battery up to an approved battery charger overnight every 1-2 months. Modern ‘smart’ chargers switch off automatically once the battery's fully charged, so you can leave them connected safely."
The rising trend of working from home has also created unexpected battery problems, with many vehicles sitting unused for days or weeks at a time.
“If you're going on holiday or your car's in storage, either get a friend to take it for a long drive monthly or invest in a charger that can stay connected continuously. Some setups even use solar panels, so your vehicle can remain locked," Mr Keane said.
Battery World offers free battery testing at all stores nationwide, helping drivers identify potential problems before they're stranded with a flat battery.
