Flat batteries are a common cause of breakdowns in Auckland and across New Zealand. Understanding what causes them helps you avoid unexpected failures.
Leaving Lights or Electronics On
Headlights, dome lights, or accessories left on can drain your battery overnight.
Short Trips
Driving only short distances prevents the alternator from fully recharging the battery.
Corroded or Loose Connections
Dirty or loose battery terminals reduce charging efficiency.
Extreme Weather
Cold winter mornings and hot summer days can both shorten battery life.
Faulty Charging System
Problems with your alternator or wiring can leave your battery undercharged.
