Home batteries installed to the standard by an accredited installer are designed to be safe, but where one can go depends on its type and the rules.

By Aaron Midgley, Arlite Energy Last reviewed 30 October 2026 4 minute read

**No DIY.** Electrical work must be done by a licensed electrician. Never open, repair, test or modify electrical equipment yourself, even if it looks simple. This guide explains what is happening; it is not a how-to.

7. Frequently asked questions

Home batteries installed by an accredited installer to the current Australian standard are designed to be safe, but location matters. Whether a garage is allowed depends on the battery type, fire separation and the rules in force at the time. The standard has changed over time, so confirm the current requirements with your installer.

## Are home batteries safe?

A home battery stores a lot of energy, so it needs careful design and installation. Modern products are built with protection systems, and the installation standard exists to reduce risk. Safety depends on a good product, a correct installation and a suitable location.

The standard for battery installations is AS/NZS 5139. It has been updated, and its location rules have changed over time, so an older article or an older installation may not reflect what is required now.

## Can a battery go in the garage?

Often garages are discussed, but there is no simple yes or no. Whether a spot is acceptable depends on the type of battery, how it is fire-separated from the house, how close it is to other things and what the current rules say. A location that was fine under one version of the rules may not be under another.

Your accredited installer should be able to explain what applies to your battery and your property. They should also tell you where the battery has to go before you buy, because moving it later can be difficult.

If a battery is damaged, hot or smells

If a battery is swollen, leaking, hot, noisy or smells of burning, or there is smoke or fire, leave the building and call 000. Keep children and pets away, and do not touch it or go near fumes. For any other concern, contact your installer or a licensed electrician. Do not open the battery or its cabinet.

## What should a proper installation involve?

A licensed electrician, working with an accredited battery installer, should handle the installation and the connection to your home wiring. The network provider also needs to be notified when a battery is connected. That is part of the installer's job, but it is worth asking whether it has been done.

## What should I ask my installer?

- Which version of the standard does this installation follow?
- Why is this the right location, and what would make it unsuitable?
- Is the battery and the installer accredited?
- Has the network provider been notified?
- What does the manufacturer say about location and clearances?
- What should I do if I am worried about the battery?

## If you already have a battery and are unsure about its location

1. Find the paperwork — Locate the installation documents, invoice and the make and model of the battery.
2. Look, without touching — Note where it is, what is nearby and whether it shows any messages on the display or in the app.
3. Ask your installer — Ask whether the position meets current requirements, and keep their answer in writing.
4. Get a second opinion if needed — A licensed electrician can review the installation if your installer is unavailable.

## What about heat, water and other hazards?

Manufacturers publish requirements for temperature range, ventilation, clearances and protection from water and impact. A garage can be hot, can flood and can be knocked by a vehicle. These are things an installer should weigh up when they recommend a location, and it is fair to ask them to explain their reasoning. If you are buying a battery, ask for the location in writing as part of the quote, and avoid agreeing to a spot only because it is convenient. A good installer will be comfortable explaining why a position works and what the alternatives were.

## Frequently asked questions

- It depends on the battery type, fire separation and the rules in force. Your accredited installer can confirm what applies to your property.
- Installers normally notify the network provider as part of the installation. Ask yours to confirm it has been done.
- No. It is electrical work that needs a licensed electrician and an accredited installer.
- Not necessarily. The standard has changed over time, so ask an installer to compare your installation with the current requirements.
- Keep away and keep others away. If there is smoke or fire, leave and call 000. Otherwise call your installer or a licensed electrician.
