Battery life and battery checks in Australia

Phones, laptops, e-bikes, e-scooters, cars and household devices all depend on batteries that wear out over time and, in the case of lithium-ion and button batteries, can be dangerous if damaged, charged badly or swallowed. This page describes what affects battery life, where phone makers say to look for battery health, the signs of a weak car battery and how motoring clubs check them, what fire services and the ACCC say about safe charging and storage, the mandatory button battery standards, how to recycle batteries through the official national scheme, and what consumer law says about faulty batteries, with links to official Australian sources.

The guide

What wears batteries out, how to check phone and car batteries, safe charging and storage, button batteries, recycling, home solar batteries and your consumer rights.

What affects battery life

Most rechargeable batteries in phones, laptops, power tools, e-bikes and e-scooters are lithium-ion. Apple describes lithium-ion batteries as consumables whose capacity to hold charge diminishes as they age, and says this chemical ageing reflects not just time but charge cycles and how the battery has been cared for. Google's Pixel help similarly says temperature, charging and discharging, and device usage all reduce a battery's capacity over time. In practice that means a battery gives fewer hours between charges as it ages, even with careful use. Laptop, tablet and power tool batteries age in the same way; where to find a laptop's battery health indicator depends on the maker and operating system, so use the maker's own support pages.

Heat, cold and storage

Heat is the main thing to avoid. Apple advises against charging or leaving a phone in hot environments, including direct sun, for long periods, and says ambient temperatures above 35° C can permanently damage battery capacity; it says cold weather can reduce battery life temporarily, returning to normal once the battery warms up. The ACCC's lithium-ion batteries guide says to store batteries and devices in cool, dry places out of direct sunlight and to avoid hot places such as parked cars. Apple also warns that storing a battery fully discharged for a long time can leave it in a deep discharge state where it can no longer hold a charge, so store spare devices and batteries partly charged and follow the manufacturer's instructions.

Checking battery health on a phone

On an iPhone, Apple's support page says to open Settings, tap Battery, then tap Battery Health; it shows Maximum Capacity, which Apple defines as the battery's capacity relative to when it was new. On a Google Pixel, Google's help page says to open Settings, tap Battery, then Battery health, with Battery capacity shown under that menu; Google says the feature is available on Pixel 8a and later models, and shows a status of Normal, Reduced (capacity below 80 per cent, where Google suggests considering a replacement) or Unavailable. Menus differ between models and software versions, so check your device maker's own support page.

Signs of a weak car battery

Motoring clubs describe similar warning signs. The NRMA lists a sluggish start, an engine that cranks but will not start or will not crank at all, needing frequent jump-starts, and a cracked or swollen case or leaking acid. RACV adds a clicking sound, dim lights, slow wipers, dead remote locking, corrosion or swelling around the terminals and dashboard warning lights, and says short trips, long periods parked, accessories left on and extreme temperatures all shorten battery life. RAA notes you may not get much warning before a battery dies, and that a battery warning light can point to the car's wider electrical system rather than the battery itself.

Getting a car battery checked

State motoring clubs offer battery checks and mobile replacement, with services, areas and conditions that vary by club and membership. The NRMA describes a battery health check that tests for weak cells and faulty connectors and gives a report on condition and expected lifespan; RAA says its patrols and Battery Service Centres can test batteries with an electronic tester and suggests testing every year, ideally before winter; RACV says its technicians check whether a battery needs replacing or can be fixed; RACQ and RAC WA offer mobile battery replacement. Check the club's own page for what is included and any fees.

Lithium-ion battery fire risks

The ACCC says lithium-ion batteries can be highly flammable and, if faulty or badly handled, stored or disposed of, can catch fire, explode or vent toxic gas. Fire services in New South Wales, Victoria, Queensland and South Australia list the same warning signs: swelling or bulging, leaking, cracks, dents or crushing, overheating, strange smells, hissing or popping, vapour or smoke. Do not use or charge a battery or device showing any of these signs. The ACCC notes there is currently no national mandatory safety standard for lithium-ion batteries or the products that contain them, so buying from reputable suppliers and following the manufacturer's instructions matters. If a battery is smoking or on fire, fire services say to leave the area, close doors behind you if it is safe, and call Triple Zero (000), even if you can no longer see flames or smoke, because lithium-ion batteries can reignite and give off toxic gases; do not touch it or try to put it out. Fire services in NSW and South Australia advise keeping a damaged battery that is not burning outdoors on a non-combustible surface at least 3 metres from buildings and anything that can burn.

Safe charging at home

Fire services and the ACCC give consistent charging advice. Use the charger and cable supplied with the device, or a compatible replacement the manufacturer recommends; a plug that fits is not proof the charger is compatible. Charge on a hard, non-flammable surface such as concrete or tiles, never on beds, sofas or carpet, in a room with a working smoke alarm, and away from exits. Do not leave devices charging while you sleep or are out, unplug them once full, and let batteries cool after use before recharging. The ACCC gives the same advice for power banks and says not to leave them in parked vehicles.

E-bikes and e-scooters

Large e-bike and e-scooter batteries carry more energy, and South Australian fire services say e-micromobility devices are the leading linked cause of lithium-ion battery fires. Fire and Rescue NSW advises charging them in an open area such as a garage or shed, away from exits and not in or near bedrooms or living areas, and never while asleep or away. Fire services warn against modified, second-hand, aftermarket or home-built battery packs and mixing chargers and batteries. NSW has introduced its own safety and information standards for e-bikes, e-scooters, their batteries and chargers, with approval marks to look for, and the ACCC says it is working towards national e-micromobility safety standards.

Button batteries and the mandatory standards

Button and coin batteries are found in remote controls, car key fobs, watches, scales, calculators, greeting cards and many toys. The ACCC says they are dangerous to children if swallowed or inserted, that children up to 5 are at greatest risk, and that serious injury can occur in as little as two hours. Four mandatory standards apply: safety and information standards for button and coin batteries, and for products containing them. They cover secure battery compartments, compliance testing, child-resistant packaging and warnings, and the safety standard for products applies to new and second-hand goods supplied on or after 22 June 2022. Store new and used batteries out of reach, tape both sides of used ones, and if a child may have swallowed one, call the Poisons Information Centre on 13 11 26 immediately without waiting for symptoms.

Recycling batteries: never in kerbside bins

Batteries should never go in household rubbish or recycling bins, because they can start fires in bins, garbage trucks and waste facilities. B-cycle is Australia's official battery recycling scheme, run by the Battery Stewardship Council and authorised by the ACCC; it says drop-off at its points is free and takes loose household batteries, button batteries, rechargeables, power banks and removable e-bike and e-scooter batteries, with a 5 kg drop-off limit. Tape the terminals with clear tape first. B-cycle says phone and laptop batteries, car batteries and home energy storage go through other channels, and damaged or swollen batteries must not go to a drop-off point: contact your local council. Planet Ark's Recycling Near You lists local options.

Home solar batteries

Home battery systems are a specialist area with their own rules, so this page only points to the official bodies. The Clean Energy Regulator's consumer guidance on the Cheaper Home Batteries Program says to ask for evidence that a battery is on the Clean Energy Council's approved list, to make sure installers are accredited by Solar Accreditation Australia, to find sellers through the New Energy Tech Consumer Code, to keep the written documentation, and to have the system checked by a licensed electrician. Electrical safety regulators in each state and territory oversee installation safety.

Faulty batteries and your consumer rights

Under the Australian Consumer Law, products, including batteries and devices, must be of acceptable quality, which the ACCC describes as durable, free from defects and fit for purpose by the standard a reasonable consumer would expect. If a product has a major problem, you can choose a refund or a replacement; for a minor problem the business must at least repair it free of charge. The ACCC says these rights are in addition to any manufacturer's warranty and cannot be taken away. Contact the business first, then your state or territory consumer protection agency if it is not resolved.

Questions to ask about a battery

Plain questions worth asking before you buy, charge, store, replace or throw out a battery, and checking against the official pages linked above.

Is the battery swelling, leaking, cracked, hot or smelling odd?

Fire services and the ACCC say to stop using and charging it straight away. Keep a damaged battery outdoors away from anything that can burn and contact your council about disposal.

Am I using the charger that came with the device, or one the maker recommends?

A plug that fits is not proof of compatibility. A charger with the wrong output can overheat a battery.

Where and when am I charging?

Charge on a hard, non-flammable surface with a working smoke alarm nearby, away from exits and soft furnishings, and not while asleep or away. Unplug once full.

What does my phone's battery health menu show?

Check the maker's support page for the menu path. A reduced capacity reading means shorter use between charges and may be a reason to consider a replacement.

When was my car battery last tested?

Motoring clubs suggest regular checks, especially as a battery ages and before winter or a long trip. A slow start, clicking or dim lights are signs to have it tested.

Does this product use a button battery, and is the compartment secure?

Check that the compartment is screwed or locked shut, store spare and used batteries out of children's reach, and know the Poisons Information Centre number: 13 11 26.

Where will this battery go when I am finished with it?

Never in a kerbside bin. Tape the terminals and take it to a B-cycle drop-off point or another option listed on Recycling Near You; damaged batteries need council advice.

Is the fault covered by the consumer guarantees?

A battery or device that fails sooner than a reasonable consumer would expect may be covered even after the warranty ends. Contact the business first, then your state or territory consumer agency.
