🚤 Before you buy a new boat battery… make sure you know what job it needs to do.

Starting?
Deep cycle?
Dual purpose?

They might look similar, but they’re designed for different types of work — and choosing the wrong one can leave you with a battery that doesn’t perform the way you expect.

We’ve broken it down in our latest Battery Hub article

Thinking about buying a new deep cycle battery for your camping, caravan or boat? 🤔

One of the most common questions we get asked is:

“What size battery do I actually need?”

The answer isn’t always as simple as buying the biggest battery you can find. The right battery depends on:

✅ How long you need power for
✅ What appliances you’re running
✅ How much power they use each day
✅ Whether you’re choosing AGM or Lithium

We’ve put together this simple Battery Runtime Decision Flowchart to help take the guesswork out of choosing the right battery.

Have a look and let us know what you think.

We’d love to know…

What’s the biggest thing you’re powering with your deep cycle battery?

* Camping fridge?
* Caravan?
* Boat?
* Something else?

The Cost of Being Caught Out

Last week should have been all about celebrating my daughter’s birthday.

Instead, I spent the day dealing with the aftermath of an attempted burglary.

The burglar didn’t manage to get into the house and didn’t steal anything, but they still left me with more than $400 worth of damage after destroying the external meter box. The result? A day without power, an unexpected electrician’s bill, and plenty of stress.

It was one of those frustrating situations where you’re left thinking, “What a waste.”

Nothing was gained. Money was spent. Time was lost. Stress levels went through the roof.

As I stood there waiting for the electrician, it got me thinking about all the other unexpected problems that can suddenly derail your day.

One of the most common?

A flat car battery.

Unlike a burglary, a battery failure is often something you can see coming—if you know what to look for.

I’ve written a new article about how small problems can quickly become big, expensive headaches, and why a simple battery health check could save you from being caught out when you least expect it.

Here’s your reminder that New Zealand is pretty bloody spectacular.

Somewhere out there, a jet boat is carving through an icy river, surrounded by snow-capped mountains, while most of us are sitting at our desks wondering what’s for dinner.

⚡ What’s the worst place your car battery has ever died?

❄️ Cold winter morning?
🛒 Supermarket carpark?
🏖️ Holiday road trip?
🚜 Out on the farm?

Most of us have a story.

That’s why buying a battery based on price alone can sometimes become an expensive mistake.

We’ve just published a guide explaining why some batteries are so much cheaper than others, what you’re actually paying for, and when a cheaper battery might be perfectly fine.

Have a read and let us know if you’ve ever been caught out by a flat battery.
