OUTBACK CHALLENGE

I take issue with you saying a car’s battery life “is about three to five years”. It’s heavily dependent on climate. In nearly 60 years of motoring in Australia’s north, I’ve found average battery life is rarely over two years. Here in Darwin, anything more is a bonus. Robert Fox, email

Fair call, it’s a tough climate up there. I note battery brand Supercharge sells Gladiator batteries – suited to extreme hot climates – with a 48-month warranty for non-commercial use. They have dealers in Darwin and may be worth a try.
