Can Car Batteries Survive Being Wet or Is It a Recipe for Disaster

We’ve all been there. Perth throws one of its cheeky downpours, you pop the bonnet to check something, and suddenly you’re wondering — “Oi, can my car battery get wet?” Short answer? It can... but it shouldn’t.

Car batteries aren’t like your footy socks — they don’t need a rinse. While a bit of rain won’t immediately fry your ride, excess water can cause corrosion on the terminals, short circuits, and eventually, you'll be ringing us to ask why your car's more lifeless than a Sunday arvo after a Bunnings run.

Perth weather loves extremes, 40-degree scorchers one week, surprise storms the next. This combo can crack your battery casing, let water in, and weaken your battery faster than a meat pie disappears at halftime.

So what’s the go?

Here’s how to keep your battery drama-free:

• Don’t leave your bonnet open in the rain (we know, genius right?)

• Clean corrosion off terminals with a bit of bicarb + water

• Check your battery cover or tray isn’t cracked or loose

• If your car's been flooded — stop reading and contact us ASAP
